The long version: Woke up almost 2 hours late for work, skipped the normal morning routine, hopped on the bike half naked, ignored all traffic laws, and was swiftly rewarded with a train parked on the tracks, blocking the road. 1/4 mile from work. killed the engine as I don't have an exhaust system, and the noise irritates me if I'm idling for long periods of time. After about 15 minutes I decided I could have driven around the train by now. So I started it up, and proceeded to take the 3 mile trip around the train. Made it about 500 ft, bike died. This actually happens to me a lot, as My gas gauge hasn't worked for a few years. But it wasn't a no gas kinda death, sounded more like loss of compression to me, engine was speeding up but with no performance. And it'd only restart if applying throttle too. So I pushed it (literally) around the train, since I was on foot at least I didn't have to stick to the roads this time. Quick lookover on the engine, noticed a lot of oil over one side of my center stand. Checked the oil, notta. Sent a co-worker to the store for some oil so I could attempt a ride home later in the day. After work made a funnel started pouring it in. As soon as the oil went in, it poured out on the other side. Just as fast. So pushed the bike the entire way home. Fracking Steep hills and all. Fairly certain I lost 1/2 of the 20#s I've added in the past year. Anyways today is a newday with sunlight, I just gave my bike a better inspection. and found the source of the oil leak. The short version. Reference the attached pictures, puh puh please. I need to know the threading and size, so I can go to the hardware store and attempt to replace this bolt. Also mechanically inclined people, I have a secondary question that well I honestly was just gonna try it. from what I can tell this bolt doesn't go all the way through, nor does it seem to be holding on a gasket. So I'm hoping replacing the screw would be enough. But if anyone knows for sure, Should I be ordering a gasket right now, and if so which one. It's a 150cc longcase, replacement engine actaully with less than 500 miles on it. I'm sending an email off to the ebay store, to see if they can help, but it's fleabay they have their positive feedback so even getting a response is doubtful. Attachments:

I wouldn't order anything until I knew there was a need for something. You will be blessed if the engine isn't toast. Replace the bolt and see if it even starts. Running a scooter without oil and no exhaust generally causes massive amounts of damage to large expensive parts... Hope it all goes fine.

Oh and sorry I imagine all the case bolts are the same pull the one next to it and see if it fits if it does take that one to the store to match it

Are you saying it's the same threading and width as the oil plug? All though it was acting like one without being in, it's not the oil plug bolt. That's on the very bottom. because of the width of the head to oil plug, there wouldn't be a possibility of attempting to put it in that whole to check the threading without removing the center stand and the belt cover casing. I can't remove any other bolts, for there are none on that side of the engine. of the approx same size. All the others are a much smaller head and go to the belt cover. I've also tried one of the swingarm bolts, but it was to small too.

YEAH!!!!! Motofino to the rescue.... To answer my own questions should there be a next guy to this thread... The missing bolt is called a flange drain bolt. Yes there should be a gasket, didn't catch the name of the gasket, but it would be part #11 in the following diagram along with the bolt being #10. ep.yimg.com/ca/I/yhst-15150601893580_2247_4174582I've ordered both and when they arrive I will put the damn bolt to a threading guage and finish answering my original question. And I see now millsc covered that bolt with his first link, but where's my gasket?! j/k (Honestly, when I saw that pic, and how little it was I thought it was the oil plug to a 49cc or something. I would have thought that this missing bolt was at least 2 inches in length. (It's a deep boring, apparently unnecessarily done.) <~~~~ VEry unlike the Chinese.

For exhaust bolts mine use M8125 X xmm as my pipe was thinner than stock and I had to ad a stack of washers to keep it from hitting the rear wheel . I had a bolt come out before so I knew which size I used just had to measure the length . I put on a washer on the outside edge of it too and so far it has remained tight . Harbor Freight has screw gauges that tell diameter , width and thread count for a few bucks in mm
