I was thinking $1500 to 2000. Gotta hide it from the wife. Along with the new rear end and fuel injection needed for my old car!

Since making it a "big bore" is not an option I would probably do some porting, mill or change the head (Bud, Harris, Langston, etc.), maybe reed cage and reeds, change the pipe, get timing and jetting perfect, and let her rip.

For the record this is what Harris performance does to their top tier YZ125. I am not affiliated with them, just sharing info.

You don't say what kind of bike it is but you don't leave many options.

Porting, compression, pipe and maybe see if you can get some oversize or rough power valves and grind them to fit better for more low end power.

Ah, okay I understand now.

The head stay is in the right spot it is the spigot for the water inlet. In that case never mind taking it off, just refer to my previous statement about cooling inlet location.

If it were me I'd buy a good used head of off ebay and make it right, but I understand about limited budgets as well.

I wouldn't expect you to have an issue unless you ride at a pro level, and even then probably not.
