Auto de-com cam question
Posted June 10, 2004 - 03:51 PM
Has anyone had a dealer do this for them? what was the shop cost?
Also what cams would you recomend, the Yamaha cams or an after market company.

You should use a torque wrench though on cam shaft housing bolts, so if you dont have one, buy one.

Once you pick a cam, have the tools and you are mechanically inclined you should be able to do it. There are a number of posts with PDF instructions that appear to be very good and similar to the original owners manual for cam replacement and shim adjustment.
The only reason I haven't done the swap yet is I don't have much time to ride and want to be able to go on short notice, so I'm saving it for a winter project.

Everytime I have to start my bike at some lousy sidehill angle, I am glad I can do it while sitting on the bike instead of jumping up and down using the routine...
I did it myself in one evening. If you can change your own sparkplug and oil, you can do this mod...
I bought my cam from www.worldofcycles.com for about $106.

I didn't really notice any "hit". It did make the front easier to loft over say a water trap at speed.
I did already have a YZ needle.
I ride tight trails with rocks, roots, water, etc., typical Michigan woods terrain.

The YZ cam makes the bike more like a 2 stroke, great for everything but tight trails.

Check your PMs. I'm curious what problems that you had with the painted timing marks. Those are put on using a jig, and the chances of being incorrect are slim to none. You should have also seen about a 10% gain in performance.
