Well... I'm gonna resurrect this thread for a bit. I have amassed an alloy barrel, various gaskets, a boyer ignition coil, TM32 flatside carb, the carb manifold and have a line on a new head...since I've got a goldstar silencer, an ACE air can, a set of new main bearings. I am thinking of fore going the high compression piston, and reworked crankshaft and putting what I have on the bike...and see how it goes. I do have an extra 535 alloy barrel if anyone would like it since I can't use it.
