is this a 1985 yamaha phazer?? if soo then first thing is put a better track on it, then try and see if you can put like a exciter engine in it(570cc), after that the yamaha phazer isnt the fatest thing in the world and i would try to find a nice exciter and put a better track on it when you do get it!

oo ok well then try it, you most likely will have to change the motor mounts and where they are

Hey, you just never know what you can do with an older engine. I have a beat up 1973 polaris colt 340 that I did a bit of tinkering with. It can beat a mid 90s 440, and I did beat a 1995 formula 500 last season at local drag. Boy was his face red! It is BONE stock, just out better plugs and wires on it, kept the original track, suspension, everything. I still like taking it out for a rip every once in a while. Its all about how you set everything up, and how you drive it. Clutching also plays a big part.
