The guy I brought this bike from went -2 in the front. I went to Ken's Cycle in the East End of Richmond and they told me that I am doing nothing but killing the bike slowly. They said that I would have been better off just going +2 in the back I would have gotten the same result with the quicker accel but less consequences. But my boy has a Ninja 12 and he said he been riding like that for 3 years and said nothing happened. Dude at Ken's told me I will have to spend like $1500 in repair because the sprocket is making the chain turn too hard in the front... and some other stuff... I just need some general input!!! Because I am about to just take the sprocket off and go +2 in the back

 

the smaller the front sprocket, the tighter the chain does have to turn...however, $1500 in repairs???? WTF???
at most it'll just make your chain wear a lil faster. it's not hurting the motor any.

 

Cool thanks cause I was getting worried for a minute there... is there any way to keep my top end speed high and still keep the take off strong as it is now??

 

usually -1 in the front is all thats recommended. I'd switch it to a -1 in the front and be done with it. Usually the best compromise for a normally ridden bike where you don't want to lose too much top end speed. I've had mine with a -1 for 7k miles with no problems at all. To keep the take-off from a stand-still strong I'd just learn how to launch properly and if you're worried about roll-ons get a bigger bike J/K. Its seriously not going to be a huge night and day difference with a -2 to -1 change

 

Thanks I might just do that... when you ride do you hear your sprocket turning like at low speeds????

 

Also what is the difference in the 520 conversion kit and the 525 factory chain/sprocket as far as performance???

 

it just takes off like 5 lbs. imo it's a waste. get some steel gears they don't wear near as much.

 

if you can hear it, it's out of adjustment and/or needs lube, for the most part.

 

Thanks because I was getting worried when I rode...

 

different sized chain/sprocket. For street uses either should be fine but if you're swapping out everything and its the same price. I got the stock 525 or 530 sprocket size so I didn't have to change everything


my chain is a little loud because of neglect otherwise known as yearly chain cleanings and having 11k miles on it
