I haven't rode my warrior in a couple months over the winter. I rode it when I got new tires for Christmas and it shifted good. A little hard but fine. I ended up breaking the linkage on the shifter and when I broke it the quad was then stuck in 2nd gear. I pushed into my barn with my clutch pulled in it worked fine. That was a few weeks ago. I go to put my new shifter on and it will shift into gear when the engine is off. But when I put it in first and I have the clutch engaged manually it's locking up. I tried playing with the clutch and nothing worked the clutch won't engage at all even when I engage it manually. I have no clue what it could be. Help please.
