heres an update on my CR80.

i bought CR85 tank, radiator shrouds, and fenders off of ebay for a STEAL!!! so this bike, with the powdercoatin, should look pretty tight when its done. especially after the engine is cleaned. and with the CR85 cylinder im puttin on it, you might as well consider it an 85!

got the cases cracked apart and crank pulled.

crank has some small marks on it, so its getting replaced.

here is the crack in the case

then, this came in at Schiets!!! Wiseco crank assembly. Comes with the crank, rod, bearings, seals, and gaskets. all for half of what factory parts are, if not more.

Next, i have to clean the cases, get the crack welded, and put it back together. i will putting a new CR85 cylinder on this motor since itll be the same price as getting my 80 cylinder plated.

Now, i just got done with the prototype of a rear axel block with SME spool/slider.

here is the design...

this pic is the stock chain tensioner, axel, and (partial) swingarm.

the gold piece is the axel block i am drawing. It will use an 8mm SME Slider with spools meant for Ninja 1000's.

with the spool/slider attached.

our 3D printer printing out the prototypes out of ABS plastic.

all printed

now i just have to have our shop cut me the aluminum parts!!!

(i am a plastic packaging designer full time, work at schiets part time, thats where im doing all this!) we have a 3D printer at work that we use for small prototype molds.

if anyone has a solid model of something they want printed, let me know. ill let you know the price!

That printer is so bad ass. when I hit the Mega Lotto first thing Im buying is a CNC an Flowjet.

we have a 5 axis mill comin in a month that we just purchased, and we have had this 3D printer since january. it has already paid for itself twice with the amount of money its saved (just from prototype molds) and from profit b/c an aluminum mold that is 900 bucks to cut on the mill, for a proto, is usually around 100 bucks worth of material to print it on the 3 printer. ive printed off so much stuff for my bikes, and just random things, its awesome!

hell the 3D printer, with warranty and training, was only 20G's. these fuckers were 60 grand 5-7 years ago.

If I had one of them in my garage, I would be able to make my aluminum motor mounts and frame slider brackets with just a push of a button! Looks sweet!

hey, if you need me to print anything for you, let me know. send me a detailed drawing, or a solid if you have it.

email is greg at firstchoicepackaging dot com at that job.

Umm.. I just might... I've got some brackets made up now... you can see what I do here: http://www.teamquazzymoto.com/for%20sale.htm

It just pays for my racing and bike goodies... just something to do on my days off from the FD

yah man, if you get somethin crazy that will be expensive to even make a proto, let me know. send me a pic or solid anytime and ill let you know!

i can print it as high density, or low density. low density uses less material and takes less time. low density still uses a high density outter shell but uses more of a waffle weave in the middle to save time and material. but for fit and function, thats all i usually need. the parts i made really didnt make a difference, b/c they arent real thick.

havent updated this in a while.

Since i printed the chain tensioners I have done a fair amount.

Finally got the motor put back together with a new bottom and top end. Got the cases welded.

I now have a brand new03 CR85 cylinder and top end. It was cheaper than replating the 80 cylinder.

I also bought a set of used CR85 shrouds, tank, and rear fender to update the look of this thing.

Then i printed some brackets for the new tank and test fit those and next week ill have laser cut stainless brackets to mount the new tank.

Here are some pics...

85 cylinder on. i forgot to order the studs on the top of the cylinder, so i put the motor in the frame and waited for new studs to come in.

192615_10150112148188360_514138359_6245210_5668506_o.jpg

all together, just need the brackets for the tank.

the brackets i designed. I want the dog bone look. Only thing im changing frmo these to the stainless brackets are the holes. They will be slots when i have the stainless made. So i can make adjustments if need be.

here are the printed mounts in action. When i get them laser cut, i will leave them raw stainless.

200881_10150139415148360_514138359_6419816_2774224_o.jpg

The plan is...

Black rear fender and white shrouds. leave the white number plates and black front SM fender.

Get the seat modified (taller) and wrapped with a new cover, black on tope, but white on the sides. So it will be like there is a black atripe down the middle of the bike from front fender, tank, seat, and rear fender. then white on the sides with the red powdercoated body. should look good.

I do have a 1994 CR250R.... hmmmm... But being in Zanesville and possibly moving to new lexington, I dont see it getting much use at all set-up that way. Would be funner than a garage full of hookers and blow, but still. little to no use would suck.

lol. I just sold an 88 CR250. Almost put 17" rims and street tires on it. What i really wanna do is sell my 85 and my 89 ninja and buy a new 09 DRZ400 and ride that. trackdays and street. CR250s are usually too big for go kart tracks. And that type of 2 stroke wouldnt be good at mid ohio. too many straights. be better at Grattan in Michigan! thats what i want the 400 for!

very nice!!! now i want to do one.... :nono:

thanks!!
