Welder's penetrate deeper!!
so I have pretty much wrapped up my front end upgrade on my 71 xs, and have moved on to rebuilding my 1972 xl250. Last summer it kind of ran, would barely hold compression. needle would go up, and fall to zero just as quickly. Before I yanked the motor out, I tried to start it. Nothing. Yanked the motor, pulled the head. The intake valves are a rusty mess. So, I'm having woody take a look at it. He's been building this era of bikes since they came out. Haven't heard back. But in the mean time, The cylinder still spec's to standard, although glazed. The piston looks perfect. So I'm thinking monkey ball, and new rings, back in business.
On to the lower case. Manual, and thumper talk, is adamant about cleaning out the centrifugal oil filter, which is un accessible unless the case cover is off. Took that off. Inside the engine looks very clean. Last summer when I was riding it, I put a cup of kerosene in the oil to loosen, clean up, because I knew a rebuild was going to happen, here we are.
The filter is bolted to the crank end, meshed to the clutch basket. Cant get to the nut that holds it on until the internal snap ring is removed, and according to the Clymer, The top just lifts off. Ok, got the snap ring off, Top is stuck. I heated it with a heat gun, several times, soaked the thing with pb blaster for 2 weeks. Last night, I said motherfucker is coming off today!!
after google imaging, and looking at them on ebay to see exactly how that top is on there, Verified it should just wiggle out/off. Took a screw driver to the center hole, wedged a vice grip to the screw, and started hammering. It came off. Its sealed with what used to be a fiber gasket, but since I fried it, I'm not sure what it was.
Guess what?!?! Spotless inside. I had read that because these filters are a bitch to get into, they never get cleaned, clog up, then no oil goes to the top end. bye, bye cam.
But now at least I know its clean. Jumped on ebay and bought 2 good used filters.
I think it was cleaned out by the kerosene I fed it last summer. When I first got it running, the motor was throwing off a lot of heat. at the end of the summer, it seemed normal. Some passage may have been clogged. and then freed up.
I wasn't planning on taking the cases apart, but with all the pb, water from the ice I used to shock the filter cover loose, acetone/atf mix, I think I may have to.
should I?I got the bike for free, mostly there, sat for 20 years, just like my 71 xs, same owner. No title. Its in his brothers name, and they haven't talked in 20+- years. I may call the state patrol to see if its been reported stolen, if not, try to get a title.
Im trying to stay super cheap on this, so that if its taken away, Im not out that much.
Not worried about it though. If I had the title, Ide bore it out, and do all the little tricks, and restore it.
