Gearing
 

I've been reading up on gearing and had a question. If I go -1 up front and +2 on the back will this mess up my speedometer reading?

Yeah, it will show you going faster than actual speed, but how much I don`t know since the factory speedo is vague to begin with. check around for posts about the "speedo healer"...

I did this on my 929 and before the speedo was off 8-9% increasingly as the speeds got higher and after the -1 +2 the speedo was 15% off 100mph was only 85 and so on as verified on the dyno so a speedo healer is next on the list.

it's like 7.5 or 8% for a -1. as far as +2 in the rear, +3 is a little bit more than -1 up front. so you would be looking at 12+% off.

i dropped a tooth once...i got a buck fifty from the toof fairy!

PMSL :D:D

i did the -1,+2 and my speedo was off 15mph pretty much threw off the entire speedo, probably alittle more above 100 but don't know exactley, but if your doing over a 100mph and u get a ticket it doesn't really matter if its 105mph or 115mph your probably going to jail either way

mang...you doing this on purpose cause you didn't know what mang was?
what is PMSL?

RE: Gearing
 

i talked to my mech he said the speedo is off from factory to start with and if you go minus 1 in front plus 2 in back it should be about right now

RE: Gearing
 

if he lied to me im going to be pissed lol

billy42 he lied to u so i guess your pissed, the only way to correct the speedometer is to get a speedo healer, but yes the speedometer if off from the factory but not real bad but when you change the gearing it is really off bad, when i did my gear change it was only 15mph i verified this with one of those radar displays that the police put out to get u to slow down but that was at 55mph, my speedo said 70mph and the radar said 55mph, but i don't know how bad it is off above that.
