Motor flutters

Post by Joel Wayne »



Just got a GL1000. PO seems to have taken care of it. It has symptoms of air control valve. I have a new one and will replace.
I think it sat. So, I ran sea foam through. Cured the high idle after warmup, but now the motor flutters. I don't notice any other symptoms, accel/decell seem fine.
Could the sea foam clean something it shouldn't have?

Can you post a short vid? By flutter do you mean hunting for a stable rpm? Surging?

I couldn't hear anything wrong, so not sure what you mean.

Same here. Maybe a little belt slap?

My phone isn't great. It sounds like George Jetsons space commuter.

Might be an exhaust leak or a loose or clogged baffle? See if you can feel any exhaust escaping around the couplings or blowing out any other place it shouldn't. Look in the tailpipes for a loose or clogged baffle.
