YZ TIMING WOW

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.

i ride places where wr cam timeing is an asset.

but when SM season comes its going to be YZ for sure. :)

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.

is there an adjustable exaust cam with the auto decomp yet?

Wanna trade bikes? I would love the magic button. :D
