I had my quad stolen a few months back I got it back from good luck an some detective work on my part I fortunately recovered it from the inpound yard.
What I wasnt so lucky w who ever the bastids who stole it it now smokes an when its sitting it wont move its like the brakes are sticking on it,it will break loose w a bang almost after alot of throttle.I had changed the oil before the ordeal so I dont know what the hell they did to it,it also wont idle too good w out the choke off until its really really warmed up.If I have to rebuild it I was gonna go 330 kit from FST and I was wondering if this is way to go an if any 1 has experience w this kit an what kinda power gains I could expect.Its a 90 something quad an it'll outpull a big rincon 680 an it was dead even w my friends 1 kodiak 450 when they tried to pull each other hooked back to back it was a dead tie they both spun.I just dont want to put a gazillion bucks into it tho.keep it realiable like it is.

 

This big bore kit looks interesting, didn't know anyone was making one. http://www.fourstroketech.net/


I know nothing about the company, but have run BBK's from Powroll before. http://www.powroll.com/


Unfortunately, they don't list anything for the old(real)King Quad. I always wished mine had a little more power too. It won't keep up on long uphill pulls but its easier to ride through the tight woods than my Vinson. It would be nice to know if this kits worth the money.........

I'd really like to know too!!!!
