What he said...MagnumRider said:nope, the final drive out of the trans. will be rotating faster than before at any given speed in relation to the rear tire. Think shifting to the biggest rear cog on a bicycle, you pedal fast and go slow. For comparison's sake, the sender would be on the bicycle's bottom bracket and would gain input through the rotating pedals.
+1...but if i doesnt come from the front wheel then the b***** rear sprocket could cause speedo to read higher but ive seen the speedo change from changing the front sprocket rather then the rear...i could see it happening if you go up 3 or more teeth in the rear...Smitty said:Many bikes speed comes off the front wheel so like LifeLiberty says it will make no difference. So check on where the drive for you speedo comes from & then do some thinking.
