366 is 80 over. I think most cylinders will only go 80 over, but I've heard the 350 cylinder will go one more than the rest. I have ran the JE piston in 2 Warriors that I had and one lasted forever and the other lasted a long time until I locked up the crank, but that was my fault (hammered down too hard for too long!) The 396 kit is for wimps! If you're gonna do it, why not go all out and get the 446?! Standard bore with the 10.5:1 JE will do almost as good as the 366. Just the weight reduction of the piston and the higher compression will help out alot. I'm not sure JE makes a standard bore. All you ever hear about is the 366 kit.</end quote></div>

The hotrods is a good kit because it requires no machining of the cases,cylinder and windage tray. All you have to do is get the sleeve bored out and it's a drop in replacement.
Wiseco makes great pistons and there quality is just as good as JE. It's just that they manufacture more so they can charge less. Wiseco has been proven to work great in the warrior/raptor and be very reliable. I would say though that for this to happen you must have a good machinest for any piston, bore combination to work right and be reliable.
Hotcams cams are pretty much the worst performing cam you can stick into an warrior engine.. yes there better then stock but both Megacycle and Web are better grinds and will outperform them.
As far as FST 466 and 396cc getting to hot and being unreliable is just a joke. Look at all the honda air cooled engines. They run forever. Personally though if I were to do a stroker motor it would be with CWR and have the 460cc done. His customer service is great and is awesome to deal with.

 

460? I'm intrigued. I thought the biggest was 446.

You thought wrong. [img]i/expressions/face-icon-small-smile.gif[/img] FST uses a 10.5mm more stroke where CWR uses 9.5mm like powroll.
CWR uses a 89mm overbore and FST uses 87mm.
CWR also uses more compression. 12:1 instead of around 11:1.

 

CWR? So thinking wrong is good? Sweet... If its a 460 with 12:1 compression how reliable is it? and wouldnt you have to run race gas also?

Appartly he says good 93 octane will work.. but you should call and ask him.
FST runs about 11:3.1 or so so it's up there as well and those kits last a long time. I'm sure it's reliable otherwise he wouldn't be in buisness.

 

What company is CWR?

Thanks for that link. I was loking into porting and now I think I found my place. one last question for now, Whats a TM-68 carb in your profile?

 

TM36-68 mikuni flat slide carb with accel pump. It's a white brothers carb kit. Adds some top end and mid range hp.

 

the only problem with the 396 is, the raptor is air cooled, and going that much bigger is gonna run alot hotter, i'm not saying it will make the bike overheat, but if you notice most of the quads 400 cc and up are liquid cooled, they are that way for a reason.
