Repairing and finding broken gasket  By  lain (Read 708 times)

I feel like a month is too soon to change the oil, I used to do it every 3 months or so before installing the BBK, now I also need to change mine every month.

I'm not sure if it is normal usage or not, comparing to the old non BBK setup I used to have. I find that by the time I am going to change the oil because it gets black I have lost about 1/4 of my oil. On my old 50cc setup the oil would not get black in the first month, it would slowly go from light yellow to brownish to brown to dark brown to black then I would change it by the third or forth month and it would have lost almost no oil. With the BBK it goes from light yellow to brown to black over a month.

I'm thinking the rings may have got scuffed or may have scratched something when the bolts were loose, I am going to be ordering new gaskets soon to tear it down and do a run through. Probably take an extra measure and put some gasket sealer on this time.

I never removed anything under the cylinder jug, so I never removed the part of the case that has that gasket. I checked that part of the case too, the bolts are all still factory tight, never been removed.

Only the silver cardboard stuff. The only gasket I used that is like the gasket I took out of the oil, and since it's gotta be between the combustion chamber and the oil pan, is the gasket that goes on the bottom of the cylinder jug. I may also check the chain tensioner because that also used the same gasket type. The only other spot I remember there being that type of gasket is the intake manifold, but I doubt it could find it's way into the oil pan from the intake manifold.

If there were no problems with anything, just the gasket, wouldn't I only need to replace the gasket?

geh3333 yeah I have a lot of problems I suppose from running in horrible weather all the time and using my scoot as my main means of transportation in a city that cares only about main roads... barely.

Like last night I found I heard a lot of clanking when I started up to go home. I have been outside all day cleaning the CVT and working some replacement parts in there because I found one of my plastic sliders broke, another was about to break, and the belt tore on the inside. I just cleaned the CVT till it shined like brand new metal, replaced the plastic slider things, and weighed out some weights and put in 3x8.45g and 3x8.00g weights because I wanted all even weights in there and those were what I have lying around.

Something you may find interesting is, while comparing my old variators with my current "performance" variator I found that the backplate that I put the plastic sliders on is smaller than all the stock OEM variators, however the stock OEM backplate fits perfectly into the '"performance" variator. I thought it was weird because the sliders I had would not fit into the performance back plate so I used the stock backplate instead.

Now I am currently working on how to remove a seized brake pivot from my rear drum, just came in to search the forums and internet for someone who has already removed one, found out what I'm gonna do and about to go back out and do that and grease it up right so it works right again.
