I am doing a 5K mile service on my 08 Uly. When removing the transmission plug I was surprised to see how much metal filings were on the magnetic end. I changed primary oil 2.5K ago. This seems excessive to me. Any thoughts?  I am getting ready to leave on a long Uly trip up to Glacier National Park, and want to make sure we are in good shape. | ||

I've seen worse. You are still in what I would consider break in, so I don't know that what is there is unreasonable. I just tonight did the 23k service, 5k since I last changed that primary fluid. Mine looked about the same, but without those two bigger chunks. | ||

Cpilot, Your filings look normal to me. I have seen the same amount of filings on trannys that had polished gears with less than 50 aggressive track miles on them. | ||

Thanks guys.... I am use to aircraft, and something like this would mean tear down :-).... I'll put it back together and keep on keeping on. | ||

Check the front sprocket nut. Make sure it is tight, if it comes loose it will wear the splines off the shaft. Look for a overly loose primary chain. Worth a look, i just had a complete rebuild to have the crank replaced due to that loose nut. | ||

When my front sprocket nut came loose, you could hear it as a "ringing" with each engine pulse whenever the bike was completely unloaded (neutral or clutch in). Load it up at all, not even enough to move the bike, just dragging a little, and the ringing would go away. If it were me, I would not pull the primary unless I had some other symptom... but if I did have that ringing I would pull and check it in a heartbeat. | ||

In checking the free play of the primary chain, I felt it was overly loose. I estimate about 3/4 inch of play. I now have it within the 1/2 to 3/8. I am going to re-check it in the morning when the engine is for sure bone cold. | ||

cpilot, I like to make a cold adjustment and then check the tension after the engine is hot. The chain is tighter when hot. Loose is better than tight. Be careful no to over tighten the cover screws. The same goes for the oil drain plugs. The factory torque specs for the 06 were too tight. | ||

Guys, remember the 08's have a different setup for keeping the primary sprocket on the crank (bolt vs. nut) and I believe different sized splines. It's hopefully less prone to working loose than the arrangement on previous XB's. | ||

That's normal. Clean the drain plug, put in fresh oil (use Formula +) and ride it. Don't forget to grin a lot. | ||

Thats is about what mine has looked like the first two times I have changed it, the last time for 10K it did not look that heavy but still had stuff on it. Also Sara's Scg looked about the same after initial 1K service. | ||

That is what I have seen on all three of my Buells on the first primary oil change. Much less on the second and just a fine powdery mush after that. So I would call it normal. |
