Supermono race engine(s)

[Mforza]

Looking for Skorpion or any other thumper race engine or two. Must be already build for racing. For a reasonable price.
This is for friend of mine in Europe.
Let me know if you have anything.
Thank you Martin

Martin,

The Skorpion engine is a 5 valve 660 yamaha engine out of one of their quads. You should be able to find one of those easier than you find something motorcycle specific.

Also look for XR650R motors or CRF450R or X motors

Yeah, I need to find anything that is race build and have the chain on the left side.
He would like to get something that is build so he do not have to spend time to build it first.
I told him about the XR650R. Will see what I can dig up for him
