Used HT bicycle engine upgrade parts

Hi all,

Recently my 66cc BGF RB80 self destructed, I have not done the teardown yet but see three massive scores in the cylinder walls, so thinking it was the wrist pin bearing.

For various reasons I am giving up on motorized bicycling for now, and if I get back into it later it will likely be with a bigger 4 stroke.

So selling off my HT goodies! These parts have 400 miles or less on them.

This was my bike with the parts mounted (with the original NT carb):


For now, here is what I have taken off:


Also, my 3L chrome gas tank with SBP petcock and fuel filter:


Still available
- BGF 3L chrome tank w/ SBP petcock and fuel filter. Chrome is in the same crappy quality that it came with, lol. I am including two gas caps, the one that came with my stock tank that I had to drill a hole in to vent, and the non-drilled cap that came with this new tank. SBP petcock and fuel filter are included. Tank new off eBay from BGF: $44 shipped, SBP petcock and filter $15 + shipping. My used price: $35 shipped.

Also, for local pickup only (Austin, TX area):

Blown up BGF RB80. My poor motor had only a little over 400 miles on it and lost compression while on a WOT run. Pulled the head and see metal bits and three deep scores in the cylinder.

Motor comes with slant head, Al.Fisherman clutch roller, and centrifugal clutch. My centrifugal clutch did not come with the puller, but if you can get it off, it should be in perfect shape.

Blown motor with slant head, centrifugal clutch, and random kit stuff (CDI, NT carb, gear puller): $30
