What dose MR thinkĀ ?
I very much question Ti valves (probably Ti retainers). Stock or oversize valves?? If they are Manley valves forget it (unless you get lash caps). Aftermarket springs I guess. Aftermarket crank??? Maybe an old RC crank that's been lightened. If the pistons are Wiseco's they would be OK especially if you could get a deal on the bored cylinder. Cams?? As in more than one
I don't know...you need some pics. I'd look for nice rods and check the port work. The head may be a good deal. This post needs some pics. I went on that website and didn't see anything regarding this engine.
