RS 175? No such bike, unless they made their own cylinder for a RS 125...
Not to piss in your cherrios, but I think you'll have a hard time beating a two stroke if they both have the same displacement limits. I'm not saying that it wouldn't be fun to try, but you have the altitude, the poor traction from the salt, and a 40 year old engine design working against you.
Get a Yamaha DT175 engine (single cylinder 2stroke), or a yamaha 175 streetbike from the late 60s.
Actually, you'd be better off with a 200cc modern 2stroke engine.
KTM 200EXC or something.
