I have been surfing the web for info and personal homepages on the Fourstroke tech 5oocc kit for the yamaha warrior ,But I could'nt find anything.I would like some input an the performance of it.And does Fourstroke tech have a web site or phone# so I could reach them.Any help will be greatly apprecaited,thanx

 

i hate to paint with a broad brush but... before i bought my banshee i went and looked at one. the guy told me it had blown the motor 3 times each time it was sent back to to 4 stroke tech and supposedly fixed. i guess they had some problems with the early machining to the cases?? when i went and looked at it he told me that the clutch was rattling? well after a 30yd trip up his driveway i thought the chain had popped off my to my surprise when i looked down at the motor a chunck of the case had blown out. needless to say the guy was not pleased and said that he was jerking out the $2500 paper weight and putting a stock one back in.. that was my only expierince with one. if the motor would have held toghether 10 minutes longer it would have been mine!!

 

I have a 430cc warrior this thing has killer power no problems with engine

 

i have known some guys with the 500 and the only thing that sucks about it is that it has so much power the suspension and a arms had to be upgraded. but now there awsome. they were faster than my raptor well when it was stock. make sure to get the cam and the whole works or it will be a torque monster with no top end. but with a cam and the hole kit the rip.

 

I have a 440cc kit in my warrior from four stroke tech.The motor does rip pretty hard.But it was not worth the TERRIBLE service,the lies,being ignored,etc,etc i got from him.I just want to warn you about this Mickey Dunlap guy,he is a complete *****,and I know lots more people he screwed over also.To one rider to another,find somebody else to do the work.
