Oh yeah... I got it running again. 7 hours of knuckle bashing to change-out the engine.
This is the 3rd engine for my quad and the 2nd I've built. It sure is breaking-in well. (Even without the Sparks Racing timing advance key. I forgot to put it in. So I guess it'll wait for the next re-build.)
The old engine needs a few time-serts installed to keep the valve cover from coming off. Oh... and an exhaust stud stripped out. It's been awhile since I put a picture here... so it may not work right.
I got my baby back!
04 402ex. Moose Works Power-up kit. K&N filter, WB E-Series pipe, ITP Sandstar II tires, Douglas .190 rims, ITP razor front tires, Kill switch, air scoops, and sheepskin seat cover (If I'm gonna be sittin, I want COMFORT BABY!)

Because I've put about 1,000 hours on my machine in only 5 years. That's a minimum of 4 hours per week. It's also mostly in the sand... that is murder on the quad.
oh.... and I haul a$$.

Actually, this engine is a carbon copy of the old one. 402cc, 10:1 Wisco piston. I had top take what I could get on e-bay for a new cylinder and the one I found was a 402....just like the old one. So that's cool. I'm looking into installing a 450R carb on the quad. I hear it really helps. The response of this new engine is much better than the other...probably worn rings. When this motor goes (in about a year with the way I drive), I'll change it to a 406cc with an 11:1 piston, heavy duty studs, etc.

Might also be because: sand + K&N filter = engine full of rock dust.

Calling a illegal immigrant an "undocumented worker" is like calling a drug dealer an "unlicensed pharmicist". Both are criminals!

I actually just got rid of the 450r carb I was going to put on my Z a few weeks ago. Im going to hold out and get an 39mm FCR later on.
