    Hi all,



    I have a pretty steady oil leak coming from where my crank case cover meets my crank case. Thinking about a new gasket? Anyone have ideas, thoughts, advice on this topic? My plan is to order it up, open the crank case and put the new gasket in, pretending all the while like I actually have a CLUE what I am doing! Hope you all have some thoughts...

    not a hard fix

    Invest in a hand impact so you don't end up dealing with stripped screw heads.

    If it is the left side make sure the wires run in the groove. It is quite easy to trap them between the mating surfaces. Cover should fit all the way so it is tight against the crankcase by hand before tightening the screws.



    I thought my bike was leaking like that but it turned out to be the oil seal on the engine side of the chain sprocket. My bike has a bash plate so it was not easy to see where the oil was leaking.

    Mine is leaking on the right side. I was planning on draining the oil before I take the cover off. The impact driver is a great tip. Any others before I take her apart would be great!



    Tok-Tokkie - mine is on the oil level indicator/starter side of the bike. I did have to take my skid plate off and clean some dirt and dried mud and oil off the engine to locate the leak.

    Be prepared to do some scraping to get the old gasket off. I've had the left side cover off several times and was always able to reuse the original gasket. I've had the right side cover off once, and it took 3 hours to clean the case of the old gasket.

    Wow! That's a great tip, thanks. I would have been very disappointed - and confused - when the gasket didn't just slide right off the crank case/cover.

    Will I use any chemicals or sealants or anything else in removal or application of the new gasket? Should I use a new set of screws when I put the crank case cover back on?

    No need for all that stuff, use a TIG welder.

    Tig welder ... bit beyond my limited experience - and budget!



    I took the crank case cover off tonight. I found that the screws, particularly in the lower side, were loose. I considered tightening them down again and skipping a new gasket. But I found, no matter how hard a I tried, a few of them just spun and spun, never seating themselves tight. So I took them off, finding that several screws were very loose in their slots - sloppy almost. I am ordering new screws tomorrow with a new gasket.



    The screws being sloppy seemed really strange to me.



    Additionally, what should I be careful with in scraping the gasket off. Will I scar that metal if I try to use a chisel or scraper?
