I was just looking through the parts diagrams to put together a list of the items (bearings, gaskets and seals) that I might need for an engine rebuild and I noticed that I'm missing part 20 (the forth part in from the left) as shown on this page:
It's the
filter box air restrictor. However, that part isn't on the
Central Powersports Distribution website's diagram for my bike.
If my bike
should have that part it would likely explain it running badly. I had pretty much the same issue on another used bike I bought. The previous owner had cut the opening into the air box larger and then it wouldn't idle properly. Took me ages to work out the issue, but it ran great once I did!
Does anyone have that air restrictor on their bike?
...I'd really appreciate a photo and/or description of the holes in it so I can try to recreate it
It doesn't explain the air coming out from behind the clutch slave cylinder, but there's no reason to think there's only one (more) issue to solve on this bike.
