Well...just figured out that I bent my shift fork as a result of thinking I know what I'm doing when I did a 520 conversion. Lesson learned, so I know now. I did a -1+2 on my bike. I've kinda not been liking it lately. For cruising, I pretty much stay in the mid range where the torque is decent. But when going balls out, I'm out of the gear before I get any decent power down.

Probably going to change to put a stock 520 tooth sprocket on the rear and I should be happy after that.

What bike?

Some people love it some dont, on my 98 I went -1/+1. It aggravates me at times, and Im tempted to switch it back to just -1.

If you are wanting to yank up wheelies all the time then that would work well for you. I have a 1000 and am down one in the front. It has tons of power where I want it. For me on the street I would not go beyond that gearing. My buddy had the same gearing as that on his R1 and he eventually changed it but if your bike has no balls thats one way to get some more oooommmph out of it.


Favorite thing on my bike: the miles I put on it

Make sure you have the right tool sto get that front sprocket off! Figure out what it needs cause you do not want to go running around all hairy carry!

I did the -1 +2 520 setup on my 954rr. It was +5 when i bought it. Of course the previous owner thought he was a stunter. Only went the route i did because i needed to replace the chain and sprockets and thats all the local CG had at the time. No real complaints except for the speedo being off but thats easily fixed.

Considering going back to a stock setup when its time to replace things again.

Just did a -1/+2 on my 600rr a couple days ago. I'm not one to go blasting around town at 90mph+ so the higher revs at lower speeds don't bother me in the least. Whereas I was cruising on the highway doing 70 @ 6k rpm, now I'm doing 7k rpm.

It definitely makes the bike feel more fun between stoplights since it has a bit more giddyup at lower speeds.

I don't regret doing it one bit.

Your going to need a large breaker bar or impact gun for front sprocket.

From all the suggestions Ive gotten on here for just doing the -1, Im going to try that out and see how I like it first. I can always do +2 later.

I went -1 on my gixxer 600 and need to go +2 in the rear for any decent accelleration at the track especially considering my heavy azz. Went +2 in the rear on the cbr and its great except for highway cruising but that's mainly due to the loud azz exhaust too. If you got a 600 and weigh over 200lbs and don't care much about top end then -1/+2 would suit you great.

Went -1 in the front on my R6. Definitely feels better. Just coming off of the line is a huge difference. It isn't all that hard to change the front sprocket. And as has been said, the hardest part is breaking it loose.

That said, how many miles are on your existing sprockets and chain. If they all have significant mileage, you might want to change out all three parts (chain and front and rear sprockets), as opposed to just changing the front sprocket. Otherwise, your old chain and rear sprocket might prematurely wear out your new front sprocket.
