Well, I've never heard of this happening with anyone else, but I blew the tranny in my DRZE yesterday. I was in third gear and BOOM a loud chunking noise and the bike kicked out of gear. I slowed down and took off again. First gear was OK, went into second fine, hit third and it was like neutral. Slowed down again, went back into first, and then hung in first gear. The shifter won't even budge. I rode about five miles back to the truck in first gear. Has anyone ever had problems with gears chunking? I ride 90% of the time in third gear, and I lug it pretty good at times. I also rarely shift with the clutch. I have changed the oil every 200 miles, and use Mobil 1 15W50 with X1R oil treatment. I had just changed the oil Tuesday, and had the proper amount. The engine is stock except for bolt ons, so it's not producing an unreal amount of torque. Does anyone have any experience at splitting cases and working on transmissions? I'm debating working on it my self, but I want it done right. I'm also afraid that after fixing it, it may do it again? Looks like I won't be riding until next year.
