Simple question but can't find the answer online, I bought an 07 gsxr 600 and the guy that I bought it from has bigger sprockets on the front and rear I need to replace them both, I just want to go to stock size, anyone know the size for both sprockets and chain or a good recommendation? Also the bike has a small black box under the passenger seat that says speed-o-healer, I think it's to adjust the speedometer because of the bigger sprockets but I'm not sure, so when I go back to stock size will the speed O healer need adjusting or do I just leave it be??? Thanks in advance for the help, a cheap web site to get the parts would be helpful also thnx
Stock sprocket count is 16 front and 43 rear with a 525 pitch. If you are interested in upgrading it the most common change is -1 +2 or 15 front and 45 rear with a 520 pitch.
The speedo healer is a nice piece to keep on the bike, the stock gearing can still produce incorrect readings in the neighborhood of 5-7% off actual speeds.
What is your intentions for the bike? Do you intend on replacing both sprockets and chain or do you just have a worn chain you need to replace? The sprockets will have information stamped on them to tell you what you have now.
You can purchase chain kits from motomummy.com they are a sponsor here and have some of the lowest prices on chain kits anywhere.

Well the chain seems to be in decent shape but the rear sprocket is rough, if I roll on the throttle even a little more than just cruisin it starts to slip, and I'm wanting to go back to stock size or close cuz what ever size is on it now is to much work, just to go 50 or so mph just going down the street I need to be in 6th so that my rpms aren't sky high, I do a fair amount of riding and like the power I get from the bigger sprocket but I'm pretty sure the previous owner had the bigger sprocket for stunting and what not, basically what I'm getting at is I want power but I don't want to need to be in 6th everywhere I go when I'm just going down a road that's 45mph ya know, do what size would be best also when I change em out how do I adjust the speed o healer or does it adjust itself
