I will look into the RC1080; I've already relocated my fuel pump, so the left side is basically wide open. Where does one get the RC1980? Any rejetting needed after changeing the from the original air filter?
The rule I've heard is that you don't need to change your carb
if you change just the exhaust or just the intake, but if you change both, you'll probably need to make some changes.
If you're still running the Cobra exhaust and you're using stock intake, plan on some tinkering.
