I'm new to this forum but have been riding cruisers and dirtbikes for a few years, so I have a little experience in this area. I've been a Seafoam junky for the past few years, and if I were you I'd run a half a can of Seafoam thru your next tank of gas to help lube the cylinder walls and clean out the carb a bit internally (I didn't see that you'd torn it apart to clean it, I might be wrong though). I use it every fall in all of my bikes before I store them and they come out every spring ready and rarin' to go with very little prep needed.
Case in point: 2 years ago I thought I'd have to buy a new lawnmower in the spring. I filled it with some gas with a small shot of seafoam, and put it outside in the shed for the 6 months winter seems to last for here in Canada. In the spring I pulled out this old mower, and it started on the first pull. I did NOTHING to this thing in the fall because I thought it was toast...it even has a 2-3 year old sparkplug in it! It ran perfectly (better?) in the past 2 summers than any time in the past 10 years I've owned it.
I am NOT a Seafoam rep (banker by trade), but every older vehicle I've bought in the past 5 years (1986 Honda Z50, 1985 Kawi KDX200, 2001 Kawi Nomad - 26,000 miles, 2003 Ram Hemi - 150,000 miles, 2000 Durango 4.7 - 125,000 miles, and now my new-to-me 2001 KLR - 17,000 miles) all run smoother (IMHO) after a shot of this stuff. I don;t know what's in it, but it's got my vote as good $hit.
