Justin Fleming said:They are still in buisness but very shaddy people and there numbers are very questionable. I have had one bad experience with them and thats all it took. I sent them a crank and primary gear and they wouldnt even service my items after they said go ahead and send them. They felt that I was a threat to there buisness, because I told them that I was not impressed with there numbers and that I was making more HP than they were, 1 day later they updated the website showing there 88cc from 9ish hp to 10.2 hp, But I am still making more than that out of my 88cc anyhow.....They have done work for a friend and the crastmanship was not so good.....Bearings were full of grit, they talk about taking about 2.5 lbs total out of the crank and primary gear and at best it was 3/4 lbs.
They ARE a joke. My WORST experience since getting into minis was with them. Dont get me started!!!Justin Fleming said:I think they are a JOKE
CRFRider11 said:Wow, I think you're the shady one.. I just got my crank, primary, and flywheel back from them and it's 2.34 lbs lighter than it was stock. They also ported my son's stock head, bought the higher compression stock piston, and had them use their new crank bearings. I had a local shop here do the install. They came up with 6.8 at the wheel. So I doubt their that far off on their numbers. I'm sure I'm not the only one wondering.. Since you're building motors and your friend wasn't happy with them, why would you send them your parts to begin with? Sounds kinda shady to me.

No i dont doubt powrolls claims in fact there most liklely valid. The dome on that piston is a little bigger then mine. I couldnt use it or else i would have with my decked head. I think the valves would hit if i tried it. Powroll is very reputable but a lil pricey. I have 5hp easy out of my new mill but i agree with you 7.4 is BS. thats more then a stock untouched TB88 race head which putos out 6.5-7hp. These people are a joke.OLDSCHOOL said:Powerolls stock 49cc HC piston claims 13 to 1... I think On there site do you think thats BS? that company is good in my book what do you think Ryan?
PRC Sucks...Period lets get Jim started I remember that Jim about 2 years ago
7.4 Hp thats F-in BS Big time...Boy the Sh!T keeps piling up....5Hp is Semi Beliveable i'll except that.
