Just change my 02 426 to the yz timing. All I can say is wow. I have never hit the rev limiter on my wr timing ever. I can't keep it off the rev limiter with the yz timing. What a diffrents. If you haven't done it you better.

Thats what I thought, until I started doing some technical rocky hillclimbs in 1st and 2nd gears! :shocked:I'm thinking about getting some slotted sprockets so I get get a nice compromise somewhere in the middle.

Funny, I dont have any problems on technical, rocky hillclimbs in gears 1 & 2 on my YZ timed YZ426. Hmmmm :)

What are slotted sprockets & what do they do? Ive never heard of them before.

It is hard to beat WR cams in nasty technical low speed riding. I am sure that anyone can ride with YZ timing but it is easier with the WR timing. You guys with a WR426 have the best of both worlds. Being able to switch back and forth. We have to buy a whole new cam. :)

maybe u r just a better rider than me, only had the 426 for a few hundred km's, and only been dirt bike riding for 6 months or so. Guess I'll get smoother as I get better.

Slotted sprockets are cam sprockets that are secured to the camshaft with two small bolts. There is a small slot in the sprocket where the bolt mounts the sprocket to a boss that is pressed onto the camshaft. This allows you to adjust the cam timing infinately, to get the exact power curve you desire. Using a degree wheel and a dial indicator, you can precicely set the lobe centres of the camshaft. This process is called 'dialing in the camshafts' Check the HotCams site for pics.
