Bluing? Yeah those pipes were inherited with the bike rebuild. Using them for the time being. :)

5Twins, thank you! Always suspicious of anything from Mikes, but never had a problem with stuff from 650Central (MMM) or yam650.com. Gonna save my pennies and go with your suggestion. That should work and look great on the old gal. Cheers, RIck

My '77 XS build has ended up with OEM headers, cut off several inches past the first header mounting bolts. The cheapo slip on mufflers I have are straight through and obnoxiously loud. Was wondering about Mike's mufflers and if anyone has had good results with any of them. Want a nice XS...

Gary you hit it on the head. I reset the valves starting with the RH cylinder, then rechecked my points settings, found both to be almost perfect but 180 degrees off. Switched the point wires over and she started on second kick. Damn, head scratcher is correct! That is what was wrong sir. Many...

Damn, I just bought a pair for my 77 rebuild from the same sketchy house! Gonna go check em for iron/magnetite right now! LOL

Thanks thuban, i think I'm just going to use a very thin smear of Permatex on the lower side of the base, and install the head gasket as is, on super clean surfaces, I have new copper head washers for the outboard top nuts. after five or six 650s this is the first motor I've torn down. Did an SR...

Refreshing a long neglected 77 XS top end and an age-old question comes to mind: what sealers (if any) to use on both the base and head gaskets? They are new Athenas. Gut tells me to go ahead with a thin smear of Permatex aircraft for the base, and nothing (except maybe around the chain tunnel)...
