[iamchad2k5]

i dont know about you guys, but i think that 900cc's is a little bit too much for one cylinder.

Now someone has some inside info [LOL] yep that 02 motor of Jeffs is coming along nicely now if the rod would hold together it would be in the clear. Yea and the titainium rod dosnt cut it. But what would I know. hehe

What is the CC of the motor and how many HP is he hoping for (possible more than kings 112HP Raptor) and how often would you need to fix the engine?

straight from powroll's website on their page for the 770

BIG HUGE NOTE!!!

This kit IS designed to be the ultimate in power. It is NOT designed to be the ultimate in reliability! If you are looking for a bullet-proof engine that doesn't require extensive mechanical skills to keep it healthy, check out our high compression piston kit & cam below.

Who wants an engine like that ?? I know i don't... I would also want any engine that would rev, this kit is more of a tourque monster in my opinion. If a 770 isn't a stable engine, then how could a 900 last a month ?

[Yamaharacer]

Ya your right about that but i heard he has like 4 or 5 different engines for different riding styles

As for h.p. numbers i wouldnt touch that one with a ten foot stick on these forums [lol]
The last time I spoke with Pete on this subject the cc was 895 but rounded to a good number 900 would sound better.

How often will you have to fix the machine well thats a good question depends on alot of things but expect it to be tempermental and finicky i personally wouldnt go over 770cc for reliability purposes. But I also favor a well built stock bore machine to the over bore machines.

and haveing 4 or 5 raptors or raptor engines with 2 to 4 grand in each is an option for fourum members like myself ? I think not...

[Ernie660R]

Well with that many cc's and it blows up, what is going to be let to fix. I would think not a whole lot.
Worst of all what is going to be the cost to build it?[img]i/expressions/face-icon-small-confused.gif[/img]

Some things for some people are not about costs they are about favors and putting out the advertisement.

Should be getting my 770 motor back next week. I guess we will see how reliable it is. I talked to power roll before I sent it in and they said they are having good luck with them. It's only money you can't take with when you leave.
