Idle problems

[Fish Baseball]

well a little update on the slow going it is to figure out what is keeping the little bike down.....

- runs fine now. until it fouls the plugs and puts us back to square 1.
- still fills the airbox with petrol and oil.
- the hole in the exhaust pipe is fixed!
- the fuel tank pipe (the one that switches from main to reserve) now is fixed, so the petcock actually does something now
- new cylinder head, new piston + rings.....
- carb is next on the list to replace/rebuild/murder

but the little bike runs now, and is getting better......well until it fouls its plugs and we can't start it.

Your fouling problem sounds a lot like a stuck float or needle valve that is dumping raw gas into the chamber......and then down into the oil too. Best that you NOT run it much until you get that figured out.......or the next trick will be a LOWER rebuild for new bearings.

I hope the exhaust hole you fixed wasn't the one in the bottom.......that is there on purpose to drain out water !! :biggrin:
