K&b 60?
 

ok I have this K&B engine I'll said almost new ,I never started and the compression is insane as you can see I vacuum sealed and put it away for a project that never took off ,now I bought it without the carb and the one I'm including the bore is a little smaller anyway really cool K&B.
I did not took it out from the bag so If it does not sell I won't have to re-seal it again ..
shipping negociable

It looks like either a K&B 45 or 65 Sportster Series Engine.
