Sorry I haven't returned your e-mails. My computer doesn't want to send e=mails to you. They always come back to me. I also just returned from a friends riding track up in northern wisconsin. My friend was testing his Aaen performance built racer. But anyway you need help with the jetting. Here's what I did for jetting with my TB. First as a warning I must tell you that all of my settings may not work with your pipe and clutch kit. I have a 200 main jet, a 40 pilot jet, a 6d needle (bottom clip), airscrew at 1 turn, and the stock sport slide. If you try to do this task always remember to check the plug a lot. White means lean, and lean is very bad. It blows your motor up. It takes time and patience to do this, so don't give up. If you want any of my other mods to my TB contact me. Let me know the results.....Stick
