Seriously, This is one of two pics I have of myself. I guess I need a few more huh? My ugly mug:

And the live in female. I've got a thing for redheads her name is Mocha!

How long for the Suzi pieces?

I had one once that said 'Beware cookies that contain fortunes' I was like

damn it, i sent a PM but I'm after Wheezle. if he doesn't want all of them I'll take whats left!

Dude you have more injuries that most professional riders.

Hence why THEY are professionals, and he is not sorry man gotta bust 'em

Where the hell did you find that? I've been quite a ways up 46 and I've never seen it.

You should thank me for putting up with your cranky butt! "Waaaa, I want a new team, waaaaa!"

LOL you should thank me! who else would put up with your attitude

And then Scrappy I think she thinks I'm out to get her or something

had a good time talkin with ya Trapper!

don't forget the seat when ya come back to cbus

Same here babe! let me know and I'll bring it for sure! Your always welcome, just bring your gear!

me: Trapper? like trapper keeper?

Trapper: no, like Trapper from mash

me: *confused look*

Trapper: yes, like trapper keeper. *sigh*

nice chattin with ya

Ditto! wish I could have gotten you away from the leg humpers a little to actually converse with ya! Maybe next time

Sore as hell though. I'm gonna order a Corbin this week and if that doesn't fix it I'm getting me one of those odd ass BMW Adventure Tourers I put way too many miles on this thing to be uncomfortable

But otherwise I had an AWESOME time this weekend, thanks to everyone involved for the scavenger hunt, and of course the bonfire afterwords! I'll for sure try to make the next Columbus ride.

This is dani. It's all in fun...just givin him a hard time.he said he was gonna be here.

Dave- I was lookin for you along with others then found out you bailed.WTF? LOL

and he took his shirt off why? super ghey

Sorry hun, thats life. I just looked at a T-bird, 1993 they were ready to change cats on (for a VERY exuberant price, there's two cats built into the Y-pipe something like 1200 dollars, way more than the car is worth) because it wouldn't accelerate, Took it for a ride definitely felt like it wasn't getting air in, or out. after a trip around the block, I unplugged the MAF (Mass Air Flow) sensor. Car runs like new again. Tells me several things, A) the cats arn't clogged up, B) the TPS (throttle position sensor) is good, and C) there's an air metering device thats bad. I'm not sure that that car had a MAP (Manifold Absoloute Pressure) sensor, if it did it could be that or the MAF, I'm guessing MAF. I'll test it out Monday when I have time to look at it, but for now he can drive it on the primary programming with no serious effects, just won't be getting optimal milage, which for the 5 miles a day he drives the damn thing he's not worried about it.

By unplugging the MAF I forced the computer to fall back on it's primary programming and just run off the 3 basic sensors. It worked. This means that one of the advanced sensors is bad.

what pisses me off is the 3 shops he's had it at before couldn't figure this out, one being a reputable Ferd dealer in the area. It took me all of 10 min to if not solve the problem, severely narrow it down to 2 choices.

So remember that when you take your car into a dealer. There are maybe one or two actual mechanics there. the rest are parts changers. Hook the computer up, change what the computer says. file it and ship it. In order to get to the 'Mechanic' you've got to either have a SERIOUS problem, or a very expensive problem and good credit, or you have to have gone through all the parts changers.

settle down scrappy. You gotta start somewhere. that was a logical first spot. I would have tested the fuel pump and system first with the tank out, but todays parts changers and overhead don't really like to go out of their way to do it right the first time, get the car in and out asap, if it comes back it comes back.

mmmm... Harleys...

What do you call 1200cc's of American V-Twin?

Lunch

Welcome!

I say make sure nobody stole your spark plugs...

1. As your info states the 2v makes better power at lower speeds, great for around town and big blocks.

2. valve overlap is common in 4v setups to draw in fresh air and make things work less, the 2v swirl actually has to force air in so at higher speeds its less effective.

3. no one in this thread asked for your technical ideas so me addding the piston coating isnt out of line

4. What does painting the hood of my car have anything to do with intake porting, each has its varying idea of smooth and rough and 80 is pretty smooth for an intake not a car hood.

5. You assume I am speaking of a Ford 4v head, which in reality i speak of any 4v head. So your bad for assuming.

6. I have flowed enough heads to know I want a 4 or even a 3 valve head on top of my motor if possible.

7. You need to realize your not always right and peoples OPINIONS vary, I know there are plenty of 2v cars out there that perform very well but you never see anyone swaping 4v heads for 2v heads unless its meeting a class requirement.

.....LS1tech.com is also full of people dropping LSx motors into mustangs, I have yet to see anyone drop a mod motor into a GM product... I did see a guy drop a 460 into an old GenI Camaro though, said he had the motor sitting around and it did make very decent numbers.

You also see millions of people building engines who have no business using a microwave, let alone building a motor.

If you've flowed enough heads then you'll have no agruements when I say it's a hard fact that GM's LS7, and I'm pretty sure the first gen LS6 head out flows Fords best 4v head, or allot of 4v heads in general. or haven't you flowed any GM heads? The new heads on the ZR1 and G8 are ignorant. They're getting mid/high lift numbers on stock heads that were high end big block numbers not 10 years ago.

LS7 head

.300 246 cfm 174 cfm

.550 358 cfm 216 cfm

.600 360 cfm 220 cfm

.650 379 cfm 224 cfm

Just to be fair since the STOCK LS7 heads are 'cnc' ported I dug up some CNC ported 4v heads to compare them with.

Best.

Speech.

EVAR.

so very true as well...

Not unreasonably a first inclination would be to assume that both types of mixture motion would work equally well. Up to a point they do but as the piston nears the top of it’s stroke these two forms of mixture motion diverges in characteristics. The tumbling charge motion breaks down to small tumbling eddies where as the swirl, as it gets compacted in the chamber can speed up while still retaining it’s swirling motion form. This swirling motion in conjunction with a well placed spark does a good job of effectively and rapidly burning the charge. On the other hand the tumbling action seen most often in four valve engines tends not to produce enough charge motion at low speed to produce as good results as the two valve engine swirl. Also tumble can be almost cancelled out when high compression ratio’s are used.

In addition to the lower combustion speed the inclined valve four valve heads tendency to allow the fresh incoming charge to cross flow out of the exhaust during overlap also cuts the low speed torque as well as increasing fuel consumption and emissions. With the appropriate proportioning of valves and bore/stroke, a two valve engine, with a well designed cylinder head, can out-perform a four valve engine to about 4000 rpm.

It seems your attn span is limited so I highlighted the extra important parts for ya.

coated pistons > polished pistons- better heat resistance and heat transfer is less into the piston and its a hotter burn.

Nobody asked about coated pistons did they? huh? didn't think so.

4v> 2v- 4v have the plug placed in the center to start the burn from the center and work its way out causing a full, even combustion. 4v heads are meant to swirl they are meant to tumble, 2v heads need swirl to use up the space provided by the cylinder.

theres a stupid amount of info on that site, check it out.

intakes can be ported fairly smooth for carb cars, something around a 60-80 grit. Mostly due to better castings/ intake ports/ fuel

I've looked at a few posts here and why is it a lo of you hate on Hd riders?

Because the utterly vast majority of them are weekend warriorers that think 20 miles a month to the bar and back every weekend is a hell of a lot of riding. You should see the looks I get when I tell some of them that I go through 3 sets of tires a year, it's unfathomable to them.

I 've ridden all types of bikes, and yea some of the HD riders don't wave but others do.

again has to do with whats sitting on top of the bike. if it's a cruiser I generally won't wave first unless it's a Goldwing (i love those guys, there's some great riders) or other obvious metric cruiser.

My boss is an old time HD rider and always waved and looked and commented how much he liked my other bikes.

The old timers are the best. Those are the guys that know it's not the best, know it's issues and still love them. they've got nothing to prove and could give a damn if you do either. they'll talk to you at a fuel stop, shoot the shit and ask where your going and how far they could ride with you till you gotta split. I love the old timers, they ride to ride, not to be cool when their on their way into the office, I've got an uncle like this and as much as he bitches about the bikes, he'll never own anything different. I know several die hard HD owners, they hate the bikes. always something broken, everything costs a fortune for them, and there's always something that needs a fixing. To me thats not a bike, it's an obligation. If i wanted one of those i'd get married. I pull my bike out of the garage, thumb the starter, strap my helmet on, and go. no warming up, not fussing with that or this, nothing. and about every 3-4k miles i change plugs and oil. about.

I currently own a Fat Boy, and the reason I bought it was the zzr1200 I owned was just to fast. I ran 80-85 all the time becasue that is where it like to live.

I bought the HD as a way to slow myself down and I got a GREAT deal on it.

Just an observation.

So if you wave I'll wave back

Mace

If you need to buy a different bike to justify slowing down, you need some serious work. EVERY bike ever created, no matter by whom, has had a throttle. ALL of them, and I have yet to see one make without a speedo of some sort, hell even HD throws on leather tassels like my little cuz's tricycle on the handle bars so you can tell if your moving.

I hate HD because I'm an intelligent person. You cannot sell me shit and claim it's gold. I know better. I live eat and breathe mechanics. It's what I do. I drag race, I street race, I road race. I built my first 10 second small block at age 15. I spec'd my first cam at 22, it went into a 2001 Trans Am that put 433hp/402lbs/ft tq to the wheels. I know why things work and I'm obsessed with the internal combustion engine.

Harley Davidson has failed miserably at this. Their engine is such a joke it's not even funny. for christs sake VW gave up on the air cooled engine. let it go. The sound they tried to trademark is caused by a faulty engineering design that will, and it's a scientific fact, eventually rattle it's self appart. They are cursed with unholy vibrations that they 'solved' with rubber mounts. No shit? rubber mounts? they used them in cars 60 years ago and HD just figured it out what, 6 years ago?! seriously?

Beyond that scope every other manufacturer (almost, cheappo cars still use rubber) has switched to a harder, more aggressive compound like urethane or even solid mounts to improve chassis response and make the most out of their engines. they've done this because they've evolved their engines, making them smoother and less vibrations by balancing the internal parts and making them spin in unisom. The auto industry spends billions a year working on NHV (Noise Harshness and Vibrations) on their engines. HD slaps an old irrigation pump in a frame and tells you it's what all the cool kids are riding, don't you wanna be like peter fonda? and charges your a kings ransom for it.

Jap bikes, sport bikes specifically use the engine as a structural part of the frame they are designed and redesigned every 2 years, even the small 600cc variants make 2x the HP of HD's largest offereing, they have twin beam chassis with inverted forks, their all aluminum magnesium and other exotic metals and are ultra lightweight pumping out upwards of 190 hp in the new Gixxers. All that for less than 10 grand.

A base HD will run you 12 grand. that gets you an 883cc engine designed in 1910 that produces a whopping 42hp (be carefull with that!), forks designed in 1950, and admission to the flock. You still need to throw on 100 lbs of chrome at about 500 dollars, you need the HD gear to show which flock you belong to, not a riding jacket, i mean tee's, jeans boots to PROVE to everyone that you OWN a HD, you don't actually have to ride it, just so long as you own it, and the kicker is the HD window sticker for the back of your lexus, and the license plate bracket that says "I'd rather be riding my XLVSGHETHERTUDLKJJVDOW Harley Davidson" even though it's 80 degrees and sunny out.

The people are a big bitch, but my biggest is that they are junk. Period, any real mechanic who know HOW an engine works, not just someone who can change parts, someone who knows how and why air flows through and engine and what makes it tick, someone with gasoline in their veins.

since someone is bound to bring up the new wonder shitpile the twin cam let me explain that to you. They need chains and sprockets for the cams at 30k miles. which isn't really a problem since most of them never make it that far in the first 5 owners. It's a fact, I know 3 people with them that actually RIDE the damn things, and they all complain about it.

Now, let me explain what HD did here. they took one cam out, seperated it so each cylinder has it's own cam, almost like a SOHC setup. However they knew that if they put the cams on top of the cylinders, there would be many upset sheep in the flock, and they might rebel. so they put TWO cams in the motor, essencially doubling the frictional losses of a single cam. thats all they changed. no wonderus head improvements, well nothing worth speaking of anyways, no fantastic exotic valve train, nothing. they doubled the friction losses of a single cam, and called it an upgrade. and the sheep were happy.

What amazes me is HD has the POTENTIAL to be an amazing company. THIS is why I dispise them with every fiber of my being. They are utter hill jacks that are content with making crap. below 4500RPMS a 2valve head is VASTLY superior to a 4v head. 20lbs/ft tq at 2000 rpms is instantly noticable, 20hp at 10,000 is not. Torque is what moves you, and lets face it, a heavy ass cruiser spends most of it's life at or below 3k rpms. a 4v head here (and in luxury cars for that matter) is a bain, not a blessing. There are things going on inside a cylinder with air swiriling and things burning that a 2v head greatly excentuates.

With a GOOD head design, a SOHC, or cam in block setup and some liquid cooling HD could easily catch up, maybe not to todays standards, but to at least the late 90's. Wht they should do is copy the LSx cylinder head. It's a work of art. In automotive terms it's pure sex. the best cylinder heads ever produced, they flow like mad at low lift, and high (low lift is what really counts, the valve is at half lift 2x and only at peak lift for a millionth of a second, something like 90% of the air injested into the clyinder happens below 1/2 lift, think about that) they have exceptional swirl, the air enters the cylinder in a tornado vortex, spiraling down, and as the piston comes back up it squishes this tonado making it go even faster untill the plug fires, which on a the LSx 2v head is right at the top outside of the tornado making a perfect burn. 4v heads don't do this, infact they prohibit this, the plug is smack dead in the center of a dead spot and it really can't be moved, and up untill about 5k rpms they are nororiously inefficient. they have shitty emmissions, and due to low speed filling issues, make much less tq.

HD could capitalize on this making a high tq low speed motor, which for a cruiser would be ideal. and as much as I love to race, there's millions of people out there who just want to turn the key and go.

Okay this is long, no one is gonna read it, i'm done.

Actually Polishing the piston top/combustion chamber is a good idea. you don't have to go crazy and get it mirror smooth but a smooth surface does several things, eliminates peaks that hold heat and could cause pre-combustion (knocking), allows air to flow more smoothly (which in a 4v head is good because their flow characteristics suck ass anyways, as with all 4v heads) and makes it harder for carbon deposits to build up.

NOW, in a carb setup you need to leave a rough surface on the intake ports, and intake manifold to cause turbulance to keep the fuel in suspension, and should also have the intake manifold floor about 1/16th of an inch above the cylinder head floor to induce turbulance at a key point.

End of lesson

edit, also equal burn across the piston is a character of combustion chamber design mainly, unless of course you have high dome pistons (bad idea) and ideally the spark plug should be on the high outside of the chamber (such as in 2 valve heads) where the most turbulence is taking place, and the worst place for it to be is in the top dead center of the chamber (where it is on a 4v head and hemi heads) where there is little to no movement. 4v heads inheriantly have shit for swirl. Not knocking any brand schmuck so keep your panties on, just a plain old fact, look it up.

God damn L, that sucks. Hope everything is all better soon.
