Does anybody have any information on this kit?I'm about ready to purchase a big bore kit and I think I gonna go with the FST kit. What other mods are needed? Will a mikuni 38mm carb work with the kit? Does anybody know about the reliability of FST's Big Bore kits?

 

Somebody has to know something about this Big Bore Kit. Please respond.

 

i dont know about the fst, but i know that www.powroll.com has a 450 big bore kit for the warrior. hope i could help......

 

powroll makes 430! big bore kit.. bore and stroke kits

 

hey also powroll suplies ALL the parts neeeded for the kits...

 

A 38mm will work but might take a little snap off of the bottom end. The kits have been made to be as reliable as the stock motor. When you go big bore, you better have the head ported and polished at the same time too, so it wont ride like a utility bike....lol. Its also a good idea to do ahead and put race valve springs and the rest of the head work done at the same time. The engine will really come alive and fly off the bottom end. What else do you want to know about it?

 

Can't say I know much about the Powroll stroker kit, but it sure looks interesting! I won't try it for a couple more years when I need to do a rebuild. Go for the stroker!!! Alba also has a 400cc stroke kit, but it looks overpriced though. Their kit is supposed to run as reliable as stock though, and without slipping the clutch. I don't know about the clutch though, Crotts had his slipping with about a 367cc bore kit and the rest of the usual engine bonuses.

 

Mickey Dunlops four stroke tech big bore stroker kits for warriors are very reliable and make your warroir exteremly fast (for a warrior ;D) after the big bore you might want longer suspension though

Thanks for the info. I think i'm gonna go with the FST 446cc kit. I don't know what all it comes with. Does anybody else know what comes in the FST kit? I'm going to do my own headwork and send the cylinder to a machine shop to be bored for the new sleeve, that's my plan anyways.
