Yes, I got the trap out. I used the ChopCult method: http://www.chopcult.com/forum/showthread.php?t=3063
. Worked like a charm. The 3/8-18 tap cost $10, but it's worth it. There was more gunk inside there, so I'm glad I got it all out. Looks pretty good now!
Now I can start putting this whole thing back together. Hope I remember where the parts go.
I've spent about $100 on special tools to disassemble the engine, so if there's anybody in the SW Connecticut area who needs some help, I hope you'll reach out. I'll be happy to help.
Once the engine is rebuilt, I can tackle the rest of the bike. I haven't done a thing with brakes, front forks, electrical, oil, etc. I figured unless I got the motor moving, no sense having brakes!
