Got-Boost? Posted October 13, 2005 Report Share Posted October 13, 2005 This is for the Yellowbox---> http://www.blackrobotics.com/yb_home.htm This is for the speedohealer---> http://www.speedohealer.com/eng/intro.htm I have the yellowbox and it's okay but I've heard several people like the speedohealer a lot better.

SpaceGhost Posted October 13, 2005 Report Share Posted October 13, 2005 Mine does this too I never even look at it any more I just keep pace with cars....Thanks for the info, you rock! Quote Link to comment Share on other sites More sharing options...
Crash1647545504 Posted October 13, 2005 Author Report Share Posted October 13, 2005 Yea, thanks for the links. Quote Link to comment Share on other sites More sharing options...
DrEvil3264 Posted October 13, 2005 Report Share Posted October 13, 2005 I think it was probably changing your sprockets that fucked with your speedo, unless it reads through a cable on the front axle im not sure. I know that on my bike with the digital, changing gearing messes with it. Quote Link to comment Share on other sites More sharing options...
Crash1647545504 Posted October 13, 2005 Author Report Share Posted October 13, 2005 Yea, it's the sprockets. I knew it was going to change it, but I didn't think it was going to bug me. But now it makes me nervous to ride through places like Gahanna where the cops will turn around and follow me, just because I am on a sports bike, and I can't even tell if I am going the correct speed. Haha. Quote Link to comment Share on other sites More sharing options...
owndjoo Posted October 13, 2005 Report Share Posted October 13, 2005 sprockets shouldn't matter. the speedo runs off the front hub. Quote Link to comment Share on other sites More sharing options...
street pilot Posted October 13, 2005 Report Share Posted October 13, 2005 anytime you change gearing the speedo will be off. Hell, they are off from the factory. Not only is it annoying, but you are racking up more miles on your bike. I recommend a speedohealer. Its what I use and its nice. Also cool little features like top speed memory. The best part about your post is that you actually said "speedo" then "healer" ha. Quote Link to comment Share on other sites More sharing options...
Crash1647545504 Posted October 13, 2005 Author Report Share Posted October 13, 2005 Hahaha, that is kinda funny. I am going with the Speedohealer, I liek the fact that it has harnesses for my bike. Quote Link to comment Share on other sites More sharing options...
lemosley01 Posted October 13, 2005 Report Share Posted October 13, 2005 sprockets shouldn't matter. the speedo runs off the front hub. Not on all bikes. Many read the speed near the sprocket and are hardcoded with a calculation based on RPMs. Quote Link to comment Share on other sites More sharing options...
lemosley01 Posted October 13, 2005 Report Share Posted October 13, 2005 Ben, I think your speedo should be reading high now, not low. So if it says you are doing 80, you might be doing more like 65. So if you go the indicated speed limit, you won't be speeding. Run from the cops, pay attention to how fast you go, then, when they stop you ask them 'what was the fastest you clocked me - I'm trying to find out how much my speedometer error is' [edit]: I assume you dropped teeth on the front or added some to the rear?

Crash1647545504 Posted October 13, 2005 Author Report Share Posted October 13, 2005 No, I will be going with the flow of traffic (prolly about 80) but I am reading 100. I doubt everyone on the freeway is going 100. So it is deffinatly reading high. Quote Link to comment Share on other sites More sharing options...
cptn janks Posted October 14, 2005 Report Share Posted October 14, 2005 and I can't even tell if I am going the correct speed. you just need to figure it out with RPM. for example, turning 5K in 5th gear on my bike, is 65mph. Quote Link to comment Share on other sites More sharing options...
lemosley01 Posted October 14, 2005 Report Share Posted October 14, 2005 what change did you make to your sprockets? We can figure it out from there. Quote Link to comment Share on other sites More sharing options...
Got-Boost? Posted October 14, 2005 Report Share Posted October 14, 2005 sprockets shouldn't matter. the speedo runs off the front hub. Not many bikes these days use that old technology, all pretty much have a sensor on the transmission now. Even your bike... Quote Link to comment Share on other sites More sharing options...
Crash1647545504 Posted October 14, 2005 Author Report Share Posted October 14, 2005 Went from 15 to 14 up front, and 40 to 42 in the rear, with the OEM chain. Quote Link to comment Share on other sites More sharing options...
lemosley01 Posted October 14, 2005 Report Share Posted October 14, 2005 Went from 15 to 14 up front, and 40 to 42 in the rear, with the OEM chain. That is a approximate 12.5% change in gear ratio over the old ratio: old ratio = 40/15 = 2.66 new ratio = 42/14 = 3 Percent difference = (2.66-3)/2.66 = 12.5% To calculate actual speed, multiply your indicated speedoemeter by .875 To calculate how fast your speedometer needs to read to go an actual desired speed, multiply the desired speed by 1.125. Examples: 1) You are doing 100 indicated on your speedo. Your actual speed is 100 * .875 = 87.5 mph = ~88 mph. 2) you want to actually go 45 mph. You speedo would need to read 45 * 1.125 = 50.6 = ~50 mph (rounding down for safety). Of course, bike speedometers read high, so you would still be going slower than you think, but nothing we can do about that. If someone can verify my math, that would be a good idea. This is how I do it in my Cobra since I went from the stock 3.27s to the 4.30s but didn't have my speedometer changed. One more thing to consider though - you odometer is racking up invisible miles because of the error - 1.125 more than actual. So, after 1000 actual miles, your odometer will show you have ridden 1125 miles. Quote Link to comment Share on other sites More sharing options...
Got-Boost? Posted October 14, 2005 Report Share Posted October 14, 2005 Since the stock speedo is off by about 5-10% from the get go, I wouldn't use the speedo to do the math. I would just go by a $99 GPS from Wal-mart and verify your inputs on the speedohealer/yellowbox and make adjustments accordingly. The reason I say that is because even after you install the speedohealer/yellowbox, your speedo will NEVER be 100% accurate from 0mph all the way to TOPSPEED. Just about any speedo will read faster than you are actually going once over 80-100+ MPH depending on the bike and how you set the box. For instance, I set the box and it's spot on at 70mph but at 160mph it's about 8-10% fast depending on the gearing. If I set it to be correct at 160mph it reads slow by about 8-10% at 70mph. Maybe I'm getting to technical with it but if you want it to read close or spot on at 70 and below, you can do that. Just don't think it's right when your speedo says 170+mph and your not really going that fast. Quote Link to comment Share on other sites More sharing options...
owndjoo Posted October 14, 2005 Report Share Posted October 14, 2005 my bike runs off the front axle. that's why the big race mod is a spacer to replace it. Quote Link to comment Share on other sites More sharing options...

You probably don't want to look down at 170 and go "I'm coming up to this turn at HOW FAST!" Quote Link to comment Share on other sites More sharing options...
owndjoo Posted October 14, 2005 Report Share Posted October 14, 2005 130 is all it will indicate.......so more like 120 with the current gearing Quote Link to comment Share on other sites More sharing options...
