Anyone done it? How difficult is it? My '88 warrior runs great - everything works and no issues at all. I was just thinking about buying a hi-comp piston to get some more power out of it. I have good mechanic skills and normally do all my own work. This is my first quad and I have not been that 'deep' into a small engine before. Just wondering if it is worth it or not. I was also thinking I should just sell it to 'cash it out' , add a few bucks and score a nice 660 and just call it a day ...

 

That depends if you think you will be satisfied with the power. You will get a bit of a performance gain but, not huge with a hi-comp piston. If you are like I was and just couldn't seem to ever be satisfied than, ya sell it and move on. Dunno if recommend a 660 though. Better suspension than the warrior but, still not to par with the 700 or 450s.

 

Thanks Koopa. That pretty much confirms my suspicion - that I would ultimately conlcude it was a waste. Plus, it might make the warrior harder to sell. Some folks (myself included) get a little 'gun shy' when sellers start talking about modding that 'deep' into the motor. I always start thinking "hmmm, was it done right, or is this thing a ticking time-bomb they want to upload on someone else..."

Yea, I would prefer a 700 no doubt, but they are still a little out of my price range. Here in the Charlotte, NC area, you can score a decent 660 for ~ $2,500. 700's are mostly well over $3k.

 

Forgot to ask, but does anyone know what the stock compression ratio is on an '88 warrior?

 

i got it done to mine helped give it a little more grunt, Wiseco and JE are both good, stock compression is like 9:25.1 i think.

 

Thanks 91Warrior357. I did some reserach and I found others saying it was 9.2:1 ratio. Curious, now that you have a 10.25:1, do you have to run premium fuel, or could you still run 87 octane if you wanted (or had) to?

 

i would at least run 89 in it, with mine i run 93 all the time.
