I'm putting the motor back together on my warrior and i was wondering if anyone has a tutorial on how to time the cam. I didn't take the lower end apart, is there a way to time it right without pulling the crankcase cover? Thanks.

 

Your best bet is to get a Hayes or Clymer manual so you always have needed information handy. I've even seen manuals on CD on ebay for 5 bucks.
But in a nutshell, you will need to take the slotted plastic side cover off the left side (same side as cam chain) and the little black plastic plug from just above it. There will be a bolt head on the bottom one, you turn that counter clockwise until you are coming up on the piston near the top of the cylinder. With no cam in, there is no compression or exhaust stroke, so you just want to run the piston to the top, then look into the small top hole where the black plug was, and look for marks on the metal wheel turning as you turn the bolt. You will first see an "F", then a "T", you want to stop at the T mark, lining it up with the groove in the hole. You can then install the cam with the pin for the cam gear on the upper left side. Then get the timing chain started on the gear, and put the gear on the cam, lining the mark on one of the cam teeth with the line on the upper left side of the opening where you installed the cam. It may take some remounting of the chain on the sprocket teeth to get the two marks to line up. Then install the cam bolt to hold the gear on, set your valve lash and put the covers back on. This is not the best description, I know, but it covers the basics, which is why a manual is so useful.Good luck, let us know how it turns out.

 

awesome. i'm sure i can do that. thanks a lot.
