Hey guys new member on here so thanks for the add. So my buddy has a 2007 Grizzly 400 we went for a ride this past weekend and halfway through the trip his wheeler seemed to almost loose 3/4 of its power, we went through some deep water and mud so I figured he had gotten some of that good stuff in his cvt cover and it was messing with his primary, we ended up towing her back to the truck that day. So yesterday I pulled the cvt cover off and there was some dust both belt and sand/dirt so I used an air hose blew it all out and took it for a ride and the quad seemed to have little power and would top out at 18-20 mph and the primary looked like it would only engage 1/4 way or so. I brought it back pulled the primary and secondary off cleaned everything out replaced the ultramatic grease and buffed the shives, everything looks new now so it should work….. Well it’s still doing the same thing, I put it on a stand and in gear the primary runs all the way out just slowly, same in neutral, and with a load on it it only goes out that little bit the bike is not revving out either. Plug was replaced also and I ran a compression test it came out to 180 so at this point I’m stumped, could it be a wet clutch issue the diffs seem fine and oil is new and clean, the brakes are not sticking. And in 4×4 it’s even more of a dog any help would be appreciated. Thanks everyone….:gcrules:
