I didn't look at the Pistons yet. Thought about it then I got distracted cleaning carbs. I'll get some pictures when I split the case. I'll pull the Pistons out of the jugs and inspect

Haha oh she's gonna end up killing me one of these days. I might as well give her a reason! Where do you live? Anywhere close to me?
I think I'll replace all the pilot jets like suggested. The one is pretty messed up. I can't imagine they could be that expensive. Also i might as well do the vinegar trick too. Make sure these babies are clean when I put them back on

I know you ordered new pilot jets but the best way to clean them or any jets for that matter is to take a single strand of copper wire out of a 16 or 18 Guage stranded wire and use that. You just need it about 6 inches long then insert it through the hole and role the jet with your finger. The soft copper will not hurt the jet and will scrub any crap that is stuck in it out. This is cool to follow this biuld, I like the old wedge sleds.

with the ultra, and some domestic twins i fiddled with, ive found slp's recommendation a little rich, and a little on the too aggressive side for clutching also. for mountain riding that is. their chart worked fine for the trails.
i bet 250 mains is plenty rich. even with a gutted airbox. if that motor is stock other than the pipes...??
