!967 BS Engine parts

[shkard01]

So I was just so happy to find this old 1967 BS 90 motorcycle in my grandfather's barn, its a little rusty, but in time i think i can get it going once again. I was hoping to find someone who knows a little about releasing the piston after it has froze up.  It is very unfortunate that it happened, but without a whole lot of money spent on the bike, i would like to cruise down the street on it.  Thanks

I had a 100 sport in the same shape.  I fixed mine by using: "Marvel Mystery Oil" (upper cylinder lubricant) red and black pint can. Although, auto tranny fluid would probably work.  With the plug out, pour in as much as you can, then replace the plug.  Heat up the cylinder with a hair dryer or a heat gun on 'low'.  Heat the cylinder up to about 200 degrees and then let it cool down for 4 hours.  Take off the head.  Using a hard block of wood, hammer the piston a time or two and you're "home-free"
