![]() I had chunks of torn up bearing spaces all over the compartment. I supposed pieces of debris could get between the sprocket and the shift shaft and cause the marks. How much metal was on the primary drain plug when you pulled it? Were there any chunks of anything. If I were you, I'd go ahead an pull the sprockets and check the bearing. The metal plate looks like the thicker one. It looks like you have the updated chain tensioner. This is the best I could do far as another picture of the wear marks. I've tried and tried to get a better picture of the wear marks I'm talking about, but the one I have posted is the best I've got as far as showing the wear without taking the sprockets off. I'll see if I can get a better picture this time. My primary chain tensioner seems to be in good shape. The primary chain is still on it and I can move it in and out about an 1/8 inch or so. I do have some play in the sprockets, but it don't seem like the shaft is moving any. I guess the only way to find out if I need new bear or not is to get down to it and see. I'm wondering why the wear on the arm behind the biggest sprocket is evident. I agree with you on the shaft being loose while the cover is off, that sounds logical. You don't need the spring plate anyway and it will fail at some point. ![]() You may also want to replace your clutch spring plate with one fiber and two steel plates instead. If your in there you should check and replace if necessary. I've seen pictures on here of both side by side for comparison. Some of the 2000 M2's had the updated one and some did not. You also need to check to see if you have the updated primary chain tensioner. It's all been fixed for thousands of miles now with no problems. I had a fried clutch spring pack, bad main oil seal, leaking starter seal, and fried transmission shaft bearing. It's hard to say what problem was causing what. I also had a fried clutch spring pack that was causing an off balance situation that also may have contributed to the clutch/shell sprocket rubbing the shift shaft. I also had a bad main oil seal and I'd keep adding engine oil that was being forced into the primary which would then spit out the back and also the loose starter. I don't really think my primary fluid was ever dry either. I'm sure I could find it and forward you a copy. Badweb user Buellistic has been providing people with a good writeup, "primary adjustment 101". The primary chain specs in the manual are wrong!! The primary chain should be adjusted to +/- 3/4 inch travel at the tight spot. When I did that I could feel movement in the main shaft. ![]() You would need to pull the rotor/sprocket, clutch-shell/sprocket, timing chain to see the bearing. I can't say if you need new bearings, I was just sharing what happened to me. With the cover on, it should be held firmly in place. ![]() I think that the shift shaft play seems excessive because the primary cover is off and there is nothing holding the outside of the shaft in place with the cover off. In answer to your question if I ran it low on fluid for awhile I'd have to say that the right amount came out when I drained it,but Id added some to it awhile back so it might have been low for awhile and I didn't realize it. What is the right setting for the primary chain ? I have been running the primary chain to the specs in the manual. What you are telling me then, is the shifter shaft play is normal, but I probably need new bearings ? Yes, the marks are very similar to the ones you have shown. (Message edited by jim2 on November 06, 2011) Did you run it low on primary fluid for awhile? ![]() You say you had to replace the starter gasket. It never occurred to me that it was also primary fluid. I thought the oil everywhere was coming from the valve cover gaskets because there was oil everywhere from the valve cover gaskets. Oh, and also compounded by running without primary fluid because the starter was loose. This is a well know problem as the factory service manual has the adjustment wrong (too tight). The bearing problem was probably caused by running with the primary chain too tight. I assumed that my marks were caused by my bearing problem as evident in the first picture. This isn't a very good picture, but you can see the wear on the shifter shaft plate arm. My bike was shifting fine last time I rode it, but I had to take my primary cover off to replace the started gasket and noticed that the shifter shaft had a lot of play in it and the plate had signs of being rubbed by the big gear the started engaged to start the motor.Įverything seems to be in tack, but the shifter shaft has a lot of play in it, and the wear marks have me worried.
