Does anyone know where I can get a 440 big bore kit for a warrior, and if not do you know where I can get the 400 kit. And does anyone have a torque stuffer on their warrior. Does it make any difference? Any help would be appriciated.

 

Man, I looked around abit, but the closest I could get was a 370 kit. It seems to me that alba was doing something with a 400, but I don't remember and can't find it now. You might want to check this site out though.

Since I installed by torque stuffer at the same time I installed my e-series, I couldn't tell you how much diffence it made.

 

Try Four Stroke Tech (814)842-6159 . I know they make a 435 Warpath kit.

They make a 430 kit. saw the site on an earlier post

 

Four Stroke Tech also makes a 500 kit for the Warrior!!

 

500 cc's haha now thats gotta be sick in a warrior frame!!! That would have to take a raptor easily with higher compression! I know Powroll makes a great big bore kit that is cheap but never looked at 4-stroke tech's.

01 Raptor
00 Warrior
00 Wolverine

 

Hey RaptorRidr01, How do you like that Wolverine. Been thinking about trading the warrior for one. Is the performance comparable to the warrior? Does having 4wd make that much difference?

 

Powroll has been making high performance kits for four strokes for over 30 years. Your best bet is to go with them. I hade a `74 xr75 when I was a kid and had them peak and tweek my xr. Damn that thing halled a$$. Of coarse being 12 years old I thought anything was fast. But I never had a problem with it. To this day it still runs.

 

Does Four Stroke Tech have a web site?
