So I just switched my sprockets out and my speedometer is all jacked up i went -2 front +3 rear. Should that really effect the speedometer ? Just wondering if anyone else has had same problem before .

 

HUGE speedometer change. You're looking at an ~18% difference from OEM, and ~22.5% difference from the actual speed you're going (factoring in ~5% factory error).

 

Thanks I figured it had something to do with it i just have to figure the difference so i dont get a damn ticket cant afford any more! hahaha

 

You should get a Speedohealer for your bike now. It will correct the speedometer and also will keep the mileage accurate (gear changes like yours cause the bike to think it has gone more mileage than it actually has). A worthy investment for ~$100.

 

Speedhealer shows the error even worse - stock 16/43, going to 14/46 shows a +30.4% speedometer error and +23.6% odometer error (from the Speedohealer Calculator).

Get a Speedohealer!

 

Where can i pick one up at? Ill look around online but any place suggested?

 

I got mine from Cal-Sportbike.

 

-2 on the front? I'd keep an eye out for wear on that bearing etc.

What do you do with your bike btw?

-2 in the front is = to +8 and the rear + you went up +3 there. How hard is it to keep the front down on that thing??? lol

 

Their calculators vary then, because I used the one on http://www.healtech-electronics.com/ to get my figures.

 

i try not too keep front down click on my link below thats me in buddies parking lot ill have more up later this week ill post up
