i need a web site for the 3 valve heads

 

[sik50sbrady]

none of them are proven to be good yet......(that ive seen) not worth it.

 

[chet]

rc's one that they are gonna come out with, is sposed to be good

this head is on our sdg bikes now they seem good , just want pistons and or cylinders

 

[sik50sbrady]

sdg head adds 1 hp they claim...so wut with a 2 vavle head they still only have 6 hp! haha pethetic! my 88 has more than that lol. the head might bee good on another bore thit tho, never know...

 

[promechmx]

the bikes that are released are said to be 8 hp they sure run good, better than the xtremes. they also run a 24 carb that may be why its bigger hp.

I was just wondering what the extra valve was for, is it exuast or intake?

The 3 Valve head is a complete gimmick, and doesn't flow better than any good 2V head. Many have tried to squeeze good HP numbers out of motors with it, and many have failed.



FYI, it's two intake and one exhaust valve.



Don't waste your time or money.

thats why yamaha has a 5 valve head on all 4 strokes
