Throttle position sensor - Honda Shadow Forums : Shadow Motorcycle Forum

Hey, is their anyway to check a TPS to tell if its bad? My buddies bike won't stay running unless you keep rolling the throttle or cracking the throttle halfway open. It's 06 Shadow 750 so it's fairly new. I've tried adjusting the throttle screw and have had no luck their. Not sure what else it could be?

The 2006 US Shadows didn't have fuel injection, so no TPS. Sounds like dirty carb or an air leak.

Has he messed with the carbs any? Could have the idle jets out of adjustment.

I did take the carb off myself that was the first thing I thought of was it needing a cleaning. Surprisingly it was clean with really no build up of any sort. I did add a little sea foam to the tank after to run threw the lines and what not but still no success. The fuel pours freely from the petcock which was another concern of mine maybe some debris caught in their but nope!

My 2005 Shadow Aero 750 shop manual shows a throttle sensor attached to the carb. I believe it's for ignition timing purposes and not fuel. DON'T MESS WITH IT UNLESS YOU KNOW FOR A FACT IT'S BAD.

It sounds like a different problem to me. Like maybe a clogged slow circuit in the carb or a restricked fuel tank breather hose.

Good luck to ya.
