Funny thing about all that, I removed my air filter altogether and took a test spin...the engine actually bogged really badly on initial takeoff. Makes me think the carb is configured for that little bit of restriction. I'm not gonna get into drilling out my carb and jettin up and all that jazz, I love something that starts when i want it to. I put on a smaller front sprocket and that made a little diff, but i think i just expect too much from the little thing...my other ride is a '74 vette so i spose i'm a little prejudice. Oh, and the vette absolutely hates to be woken up if it's under 70 degrees outside...ha ha.
Workin it all out,
