I just installed a Kuryakyn Pro Hypercharger on my bike. The instructions said to install the air temp sensor into the manifold bracket but it didn't say to hook it up. I have a FI light illuminated and get a backfire from the tailpipe. Other than that the bike runs fine. I also installed a Cobra FI2000 fuel processor. Thanks!

u really need a pro to guide ya here-bad jet settings can fry your engine--do some reading sec 629 library or purchase expert manuals like clymer

Take the hypercharger back off. The carb uses fuel according to how much air sucks through. You are putting alot more air through the carb, so it sucks more fuel into the engine. Even if your not burning all the fuel, it's running through anyway. That's the downfall to a carb.

The worm clamp proly did choke off the breather. Usually when oil comes out of your breathers it means there is to much oil in your oil tank.
