Hi guys, well I'm finnally gonna jet the bike and was wondering what size I should go with for the mains - I don't yet have a pipe and running the stock filter - just looking to stop all these damn long waiting periods for warm up.

Also, where can I find a 15 tooth front sprocket at a good price?

Thanks in advance!

125

the size 40 pilots are what help warm up. our bikes come stock with 37.5 if i remember right. for main sizes go with 125 for the stock set up.
