To all the guys who helped me out at race #1 I want to say thanks for everything. I really appreciate all your advice. I really contemplated selling the RC51 and buying a 600cc, but I just couldn't bring myself to let her go for as little as I would have. So I decided to take your advice on parts I just ordered michelin power pure tires with the taller rear 190/55/17, new carbon Lorraine brakes, new chain and sprockets 15 front and 42 rear, and a real good air pressure gauge. Now that I've changed the gearing and geometry, would anyone with RC51 knowledge mind helping me tune the suspension, and if I asked real nice let me borrow a chain tool and or if your afraid I might break it possibly break and press my chain on sense I was to cheap to buy one. If your interested in helping me out I'll have a 12 pack with your name on it.
