I am new to this forum, new to owning a vintage bike (haven't owned a bike for over 20 years) and just relocated to a new area. Here is what happened I have wanted a classic bike for years and living in a new town decided I would finally find one to pass the time by riding after work. I was looking for one to just putz around my small town with and after weeks of looking on craigslist this cool little CB175 popped up. I went over after work, talked to the owner for awhile and took it for a drive. Everything seemed really nice for such an old bike but needed a lot of cosmetic work at some point. Didn't care about that as my plan was to cruise around this summer and fall and come winter it would give me a good project to work on.
So the last couple days I have been driving it around not far from the house and only going a few miles. This afternoon it was really nice out and figured I would go for a 20 - 30 mile ride. Everything went great until I was a mile from home. All of a sudden it really started to bog down. Didn't want to go over 40mph at all. So I didn't push it and figured I would get it home and take a look at it. Maybe spark plug, some bad gas... Well I didn't have time. I got to a stop sign and all of sudden it started running really rough, backfired and made a load puffing or hissing sound then stalled. I sat and waited for a while thinking about what to do, push it, drive it, leave it and come back with my jeep and try to get it. I thought maybe it was just a freak thing and figured I would drive it home. It fired right up but I took it very slow and once I pulled in the driveway I let the RPM's drop below 1500 and it died and coasted in. Went inside to grab a water and came out a few mins later and there was a small puddle of oil under the bike. And now it seems like the left cylinder is not firing correctly, there is basically no flow through the exhaust on that side.
Sorry for the long post, has anyone had anything like this happen and if so please Help. Sorry I probably left some things out. Thanks
