hey guys i changed my sprockets on my 07 honda cbr 600 rr i went 1 tooth down up front and 3 up in the rearand i was wondering if anyone might know how much of a difference performance wise and RPM wise and all that that its gonna be and also the stock front sprocket had rubber on both sides of it and the new one is just steal is that gonna be a problem or cause any difference in noise or anything?
thanks guys

you''re going to be revving a LOT higher...most guys do -1/+2 and that gets you up in the revs so +3 is going to make it worse...you are going to be shifting fast with a LOT of low end torque...be careful not to inadvertently lift up the front....

and don''t worry about the stock sprocket with the rubber, doesn''t cause a problem...

dayummm, +3? That will get you some mad RPM increases...

Its also going to throw off your speedo/odo quite a lot. I recently did the -1/+1 conversion and my speedo is off about 14%, but I''m too cheap to buy a speedo healer

get a speedohealer, yes its called exactly that. it will correct your speedometer that is now thrown off by massive sprocket changes. think of it like this, the differecial is now about + 6 in the back cuz the one if the front is = 2.716 in the rear.

thats alot of torque my friend. i have one two up and it comes up like its nothin in first gear, not even wanting to. your gonna love rocket starts tho

rpms are gonna be high for regular riding and that means more gas consumption, especially with the +6 diff. just take it slow and notice the difference. its nothing you cant handle....hopefully....at least if your not a squid.
