Hey all, had a great year on track with the nc30 fork upgrade kit and shock from rick o really made the bike a pleasure to ride im stripping down to clean and rebuild for next year now i know my jet sizes were all over the place last time i cleaned carbs so wondered if anyone had advice on best jet and pilot sizes to get the most out the bike on track?? Also anyone know if theres anyother upgrades worth doing while in bits? Cheers guys any help or advice always welcomed. Pete

If you're going to do any mods to the airbox / filter or pipe do them first. Then take it to a dyno and have it set up. It will cost a bit but having it done once properly is worth a lot of time messing about.

Pete, there are a couple of extra things you can do to the carbs, check out the nc30 jetting guide in the document library: http://www.400greybike.com/docs.htm
