I'm new to the site and have found tons of great info that's helped me restore my '74 cb750k, Thanks to all!!!. Here's my problem I have aluminum shavings in my oil pan, I've pulled the pan 3x and have shavings all 3x. Heres some history, I recently installed a wesco 836 and a web cam 41a into a 78 750k lower end with only 6000 miles on it ( the motor was spotless on the inside). I used the stock clutch basket assembly with heavier springs,but I screwed up and used a clutch cover off the 74 because it looked better. There was a little nub on the back of that cover that was rubbing against the clutch basket, so I assumed this was the culprit, I cleaned everything up, changed the basket from a 78f and put the 78 cover back on. I pulled the oil pan cleaned that and the screen and also changed the oil and filter. Ran it around the block, and to make sure all is well,pulled the pan and did all the steps again!! more shavings. I thought this was remaining from the clutch basket incident. I changed the oil and filter again, ran it for a while and figured it was done with. Tonight I noticed a oil leak underneath, and discovered ther was a hairline crack where the drain plug goes, so off comes the pan again, To my surprise and horror there was more aluminum shaving. The motor runs strong with no wierd noises, knocks or anything, The carbs have been syncd, timing set, cam chain tensioner set etc. The only thing besides the aluminum shaving, is the trans is hard to get into neautral. Could this be residue shavings from the cluch incident? or do you think I have a bigger problem? It's hard to say how much shavings there were, but I would guess about a half a teaspoon each time in the pan and then the small glitter like particles in the oil and filter.Thanks in advance for your help with this.
