Hey everyone. Darn glad to have found this forum! Just bought my son a 2009 CFR70 (first bike - 8 years old) and the first thing I'm doing is scrapping the factory air box for a UNI pod filter. I'm looking for advice on how I can open up/modify the factory exhaust for more performance. I heard about removing the screen and drilling some holes but have not found those posts. Any specific advice would be greatly appreciated. (Found only a couple performance aftermarket pipes that were very pricey.) I'm thinking after the air filter change and pipe opening the main jet size may need to be increased. It's a stock 13mm Keihin carb. What size is recommended? Haven't looked at the stock size yet. I assume the needle is adjustable on the slide (but don't know if this would do any good or be necessary anyway) and hope there is an air mixture screw somewhere because it seems the carb could use a bit of adjustment now. Although next to the idle screw it looks like a brass cap or plug rather than a screw. (See photo attached.) Thanks for any advice. It's great to be part of this group. Ride on! Greg in Florida
