After reading past posts regarding Horsepower increase, I gather that a big bore kit (904), carbs, exhaust, and port/polished heads is the best combination. But installing cams can be tricky and costly (not sure if it's worth it for only a 3-5 HP increase). Any other suggestions?
What type of carbs are most popular with this upgrade and what can on expect to spend total on parts (excluding cams)?
THANKS
