[quote="Durruti, post: 343295, member: 14830"] do i have to "search" there for any broken parts from the old woodruff key?[/quote] I’ve viewed the drawings in the parts catalog of your bike and the engine seems to be very similar to mine. When I find debris in my engine (pieces of liquid gaskets, or of clutch cups or of broken keys) I find it mostly in the twin oil filter set on the left sump. You could think that debris wandering in the oil could damage something. The last Winter I brought the engine to the mechanic because I needed to ship the crankshaft to get it repaired, because of this issue: http://www.advrider.com/forums/showthread.php?t=255593. I had already removed the head, the cylinder, the clutch and other parts, but I hadn’t split it: he did. So, he checked the gears of the transmission: no one was chipped, even if I had already had the clutch cup issue and a broken woodruff key. I think that those pieces were too weak to chip the gears and that probably they were shattered by the gears and the opposite didn’t happen. So, this is another reason not to use tougher materials. Unfortunately, I don't know which is the material of the OEM keys. Anyway, I suggest that you use the OEM ones, if you can get them.
Thnx Theo! After 2 changes of oils in 2 days, (one failed and one succesfull) i believe that most of the derbis are out of engine. I think that an OEM key will take time to be found, and i need that bike working as soon as possible cause it gets me at work and back home. I'm guessing they are made by aluminium, but i'm not sure how stable will that be at high temps/pressure.
Ι went to 5 or 6 hardware stores, most of them didn't even understand what i was looking for. Pro. Finally found the OEM part from a local dealer (ok, from another town - shipping will cost twice the key, but i will live with dat).
