change up your gears, not really sure how much since i havent done it but usally like down 1 in the front and up 2 or 3 in the back is a good rule of thumb....give you a lot more snap off the line, easier to wheelie, and get it up.....loss of top speed though

Its much easier and safer to go up in the back...thats b/c you don;t have to tear into the tranny...don;t go to high b/c you will kill the top end....for good street wheelies...not fully stunted out...2 to 3 up is about as high as you wanna go.

You can change the front without thats b/c you don;t have to tear into the tranny without tearing into the tranny.

You take the left foot peg assembly off and the plastic cover over the chain just below where the shift rod goes into the motor and viola front sprocket.

Personal recommendation on anything that comes through the shop is to drop the front a tooth regardless. ON most bikes taht's a 4-6% adjustment. Meaning the motor will be spinning at 4-6% faster than stock. This gives you more USABLE power at a given speed. Say stock in 2nd your going 70mph at 9k rpm making 90hp, now you=ll still be going 70mph at 9500rpm making 92hp. So you have more power to use at the same speed.

Also as for losing top-end, most of the time with 1 tooth in the front you-ll gain a mph or two up top. Again it's the useable power thing, R6's and all other 600's are drag limited meaning they don't make enough power to push the hard enough to ovr come drag at topspeed. So now instead of having 104 hp at 160mph you'l have 106hp which might be enough to push the bike to 161mph. Get the picture.

As a side advantage a front sprocket wears out faster than a rear because it's turning 3x as many times. So you're going to replace it sooner mod'ed or stock, and a front sprocket is like $17 while a rear is $35.

I'm gonna hafta disagree with firefighter about the rule of thumb. Dropping a tooth and the front and going up 2 possible 3 teeth in the back is a pretty dramatic change. In the order of 12-14% more aggresive acceleration. You can go that high but you'll probably want to ease into the change. First the front sprocket, ride for a while. Then the rear and ride for a while to get use to the change. Also if you add more the 2 teeth on the back you'll probably need a new change with an extra link in it.

I've gone a tooth down in the front and 2 teeth up in the rear. When I let anyone else ride it that doesn't know how to handle it... 1st, 2nd, and 3rd gear power wheelies. Not whack the throttle to get it up we're talking just smoothly adding in the juice and you'll pointed to the clouds. So tread litely when you open pandora's box.

:wink: Riding 2 months? Had toooo many riding buddies get fooked-up doin' **** they should NOT have been tryin'. Get a beater bike to practice in a safe place with a buddy with a car to take to to the M.D or E.R Etc. and spare the R6 :wink:
