I have a powernow on my YZ426 it looks like it does the same thing. I can tell you it did improve my low end and throttle responce. I agree the price is too high though.

I have recently done the Valve Metered Pitot System (sounds better than ice maker valve) I used a different mounting spot and so far it works great. I was working on an idea for a needle valve on a speedo cable connected to a knob on the dash to do the adjusting when Kachess came up with this...

Well it looks like I need to move the bottom of the back shock froward to make it lean toward the back rather than the front. Wound up with not enough travel and Bang-no-workie.... Did lots of searching (as on this great day for riding and was surfing the net instead :drink: )...

Well I just upgraded from a 159 X 15 to a 162 X 16. I built new drop brackets and lowered it a bit from the MPIs that were on it, Put new billet 2 wheel kit (MMP) and a bunch of other small stuff. been working on it for a month or so. Went for first ride today and I have to say it went GREAT...

Well as it turns out its not that hard. see pic. just built a frame and used verious size shims (scrap metal) and a 2 ton jack. despite a lack of good feedback ( thanks for incouragement AKrider) and no help from my local dealer (advised to just buy a new one) it really only took about 1/2 hour...

I have had much success with a mild to mid level port and polish on everything from chain saws to dirt bikes. No sleds yet. Mostly just an enlarge of the port and a good polish, Not much if any at the cylinder wall on the two strokes. While the head is off and on the bench I have a hard time...

Cool we will have to hook up on a ride somewhere. probably lots of good areas in between us. Not alot of Yamaha guys down here, sometimes hard to find a good croud to ride with. I ride too fast for the older guys and not out for a drunk fest with some of the younger croud. Only work 1 day a...
