Looking to buy a dirt bike/motorcycle engine

[ApocGoD]

I'm looking to buy an old dirt bike or motorcycle engine, automatic or manual shift. Gas tank not required, just need the engine for a kart. Willing to trade a 12.5hp B&S vertical engine, or cash. Email me at apocgod@gmail.com or comment for info.

What size engine are you looking for? I put a 5 speed manual 138cc on a off-road
suspension kart as my first build project and with it geared right I can pull the wheels off the ground. I am not sure what the top speed potential is, it is all in the gear ratio.
