If you can get any more top end it isn't going to be much but if you want better throttle response like me I've read about a couple of things you can do.
1. Jet the carb-150 Main-38 Pilot - .60 needle shim
2. Get an advance timing Key ( I'm about ready to get one for mine) www.700v.com
3.The best thing it seems you can do is put in a EPI Black Secondary Spring in. www.erlandsonperformance
I wanted to get a pro circuit exhaust for mine but haven't yet. What do you think of yours? Did you get the 496 or the T-4? I'd really like to see what you think of it.
If you want better handling Elka makes a front strut kit that sells for $345 (another item on my wish list)
