This is an awesome read about power valve cheetahs.

yea I've read this one a couple of times now

[What size motor]

You know strm trpr I would send it out but shipping would be to much I've been doing my own work on snowmobiles last ten plus years or so. So I think I can handle it I do have a Clymer on hand and I just eyeball carbs been doing it on snowmobiles never had any problems.

[What size motor]

awesome thanks, now I just have to find a couple of pistons to rebuild and then ill be able to fly round the trails.

[What size motor]

Yea that's what I been reading I figured it was bout a 392 or something with the 68.5mm bore and 54mm stroke the guy I bought it from thought it was a 421 but after doing some reading I think its a 392 or something which is bout right.

[What size motor]

yea I did that and it measured round 5.4 cm  which would be 54mm but I still have to tear it apart regardless.

[What size motor]

I believe its a stock 54mm stroke when I tear into it ill know for sure. 

[What size motor]

Hi, first off want to say awesome site, gave me a lot of info on some different things. Recently bought a banshee, had some problems, boiled down to having 90 psi on both, want to do rebuild but not sure what size motor I have. I know its power valve cheetah. But not sure what size? On top of my dome it says cheetah 68.5 - 21 - 10. Any and all info would be surely appreciated. Thanks
