OK, so I decided to do the top end on my 2001 cr250, and of course I have some stupid questions for the sharp minds on DRN.
1.) Everything was going good until I tried to pull the jug off. For some reason, I cannot seem to pull this thing from the cases. I can jiggle it a little side to side, so i know it is loose, but it won't come upwards. I tried giving it a tap with a mallet but no joy. :bang: I thought about slipping a flat head in between there and prying upwards but that makes me a little leery. What do you guys recommend I try? I've got a friend coming over to help me tommorow so maybe our combined elbow grease can fix that little bast**d.
2.) I removed the cover form the powervalve and it is GUNKED UP!!. What is the best way to clean it. I've heard alot of people use oven cleaner, I've thought about trying carb cleaner to blast it clean but i don't know. Will any of these solvents have an ill effect on the bearings, or should I just blast those clean as well. Upon reassembly of the powervalve, should I lubricate all the parts or just a few drops on the bearings?
3.) I do not have any crows foot sockets for my torque wrench. Whats the best way to tighten down the cylinder nuts without a torque wrench?
4.) Lastly, is it imperitive to use a petroleum based oil for break in, or could I get by with mobil mx2t. I know alot of purists say use the dino, but is this truly neccesary?
Thanks .
