Been having an oil consumption issue with my warrior that I'm finally getting around to dealing with. I haven't really used it this summer since the oil issue got bad because I just recently finished doing an overhaul on the big block in my car and now it's time to give the yammy some love. I pulled the head, disassembeled it and brought the head w/ valves to my local head shop and they're going to inspect the guides and replace if needed. Motor is pulled out as well.

My case is leaking from the side seals and my shifter pivot is leaking. I bought a complete gasket kit a while back and now it's time to put it to use.

Thing is, I have zero experience working on atvs. Cars, no problem I had my 440 in pieces in my garage and built it just fine. The gasket kit came with a lot of parts that I do not recognize such as a lot of o-rings and copper washers, etc.

The warrior is a 2003, but the previous owners obviously rode it hard and put it away wet. But the only other problem I've had with it other than the oil level going down rapidly was I have a hard time finding neutral while shifting. Not a huge deal, just a bit of an annoyance.

Anyway my plan was to just replace the external gaskets that were leaking and leave the rest of it as-is. While I'm in there, is there anything else in the inside that I should give attention to?

Also, when I pulled the head I noted it was held down by long bolts. Obviously I will do a new upper head gasket but will I now need to do the lower cylinder to case gasket as well? Or will it be fine because I did not disturb it?

Also for the case gaskets, are you guys cleaning then putting them in dry? Or hitting them with some permatex copper spray or some black rtv??

Any other tips or advice that I should keep in mind while doing this would be appreciated. Thanks. :D

the neutral problem happens to all warriors, when its hot the clutch drags and makes it harder to shift into neutral i believe.

yeah thats all in the clutch basket... it get grooves worn it it from the plates repeatedly hitting it and then the plates stick in those groves and dont wanna come apart.... happens with everything after time
 
You should be ok to leave the base gasket alone as long as the cylinder wasn't shifted when you were working with it. If the cylinder shifted i'd be worried about it leaking when it goes back together.

I never put gaskets on dry, I always prep them with some blue RTV and have never had a leak or any seepage yet. When I bought my dual sport it leaked oil pretty bad, and it was because somebody put the clutch cover gasket on dry and it didn't seal up right.
