Go to motomummy.com get your bikes stock gearing numbers off there, confirm that's what you have then order a sprocket for 1 tooth less in the front and order a sprocket with 2 teeth more for the rear. If you have basic mechanical abilities and decent selection of tools you should be able to do the job yourself if not bring it by the house and I'll throw em on there for ya....

Go to the Google search at the top left. There are hundreds of posts on this. If everyone is saying the same thing. Maybe it's true. I like my stock setup though.

You will lose roughly 15 mph with a -1 +2 setup make sure you get a speedo adj to keep up the miles and also to know your mph !!.02... If it were me i would do -1 +1 ... Jus saying Motomummy has the stock gearing app on their website

A service manual and someone that knows what they are doing would be very beneficial. If you feel unsure of what you are doing, take the bike to someone that does..Incorrectly installing a chain spells diaster to your bike and/or yourself.

As far as what gearing you go with, the most common is -1/+2, -1, +1, and stock.

If you only change the rear sprocket does it still mess up the speedo?

i have a -1+2 and like it, usually cruise around 6-8k rpms, aluminum sprockets dont hold up as well as steel ones, sunstar is pretty good.

Yes... Any gear change will cause the speedo to read inaccurately. It will also cause the odometer to be off as well. Common fix is a speedo healer by Healtech or other comparable unit....
