Insane Power loss
« on: Apr 14, 2018, 23:53:05 »

Bike ran totally fine yesterday, iddled well, good power... At the end of my ride I put gas in the bike (87) and drove it home. Upon trying to ride again today the bike will not idle well and if it does it is idling insanely high. If, and when, I can get it to drive it has massive power loss between gears, and feels like its struggling to fire.

The only thing that's different is the gasoline. Any ideas?

Does it still have compression on both sides?  If it does, I'd drain that gas out and throw it in the car/truck/lawn mower/ snow blower and refill with fresh higher octane gas and see if that improves things.

The gas may have water in it or it could be stale.  If you drain and flush flush out that gas and things don't go back to where they are, something else is going on. But start with simple things

Or, if the tank had any debris and the fuel has a path to the carbs without a filter, it could be that you disturbed rust, grit or something in the tank and clogged the carb.
