grit on the cams/shims!

Hi everyone,

I've been trying to do a valve adjustment. The old gasket was a terrible mess and stuck to the aluminum, which is pitted, so I've been soaking and scraping and wet sanding the valve cover. But during this time, some grit has gotten onto the cams and valve shim buckets (probably dust and such blown onto it, my friend's garage is not exactly weather-tight). I noticed it when trying to turn the camshaft to get to another pair of shims, I can hear it, and they feel gritty. My friend says it won't hurt anything but I don't know if I believe him.

Does anyone know of a way to flush off this stuff? Like maybe pouring oil over it while sucking out the pooled up oil somehow? I'm sure there will also be little flakes of old gasket material and aluminum corrosion too, although I'm being as careful as I can.

btw I'm replacing all the gaskets I can with silicone now!

Wipe it off good, blow it down good with an air compressor? Maybe spray some WD-40 in the crevasses to get the stubborn stuff out? Turn it by hand a few times and work it until you aren't hearing grit, for sure. Then put it back together, run it a bit, and change oil/filter? Maybe do some SeaFoam in the oil and change oil again? I dunno.
 
Clean as much grit off as possible. Q-tips come to mind. Take the cams out if necessary. You don't want grit in there. Period. If you go spraying stuff at the foreign material it will wash down around the valve buckets which is not good. Pick up and wipe up the pieces out and do the best job possible.
 
Put some padding down & put the bike on it's side. Spray the top of the head liberally with brake clean or carb clean. Let it dry & pour oil over the top of the engine

Excellent idea! I think I'll try that. I assume I should pick the bike back up before pouring the oil over it, right?

You mean silicone gaskets, right? Not the gooey stuff?

Yeah, I got a roll of stuff that's very similar to the realgaskets material... I plan on cutting out gaskets for the various covers (points, clutch, etc), and the carb bowls and tops... I am using the actual realgaskets gaskets for the valve cover and breather cover.


You guys are so helpful, I don't know what I'd do without this forum!
:-D
 
keep your exposed engine parts covered with clean rags when you're not working on them.

Cinch-top trashbags are your friend.

Great idea! The best I could come up with was taping paper towels over top. I've learned my lesson about leaving stuff exposed :oops:
 
Be carefully what you use for the stator cover if you are making gaskets. The thickness of the gasket is figured in to the clearances for the starter idler gear & thrust washers
Best idea USE THE OEM or equivalent gaskets
