    carburetor spitting fuel

    Did a teaspoon oil test, still no compression so its not rings. Took off the exhaust and found the likely culprit. Cant see any evidence for bent valve, so thats narrowing it down. Fingers crossed. Carbon is the best possible problem at this juncture.

    carburetor spitting fuel

    Its all a learning process for me. Now I know to check compression after valve work every time. Shoulda known better, myself. Plus, I got my carbs nice and extra clean and even tested to make sure the coils/wires are working. Both me and the bike are all the better for it.

    carburetor spitting fuel

    Update: I think we have a winner! I dug out my compression tester and bingo, nothing on the left hand side. I realized I didnt do a compression test after I changed out the valve stem seals over the fall. Duh! 🤦‍♂️ Its been sitting since then. I hope/doubt its a ring issue, but ill do the oil...

    What are the chances it has to do with the coil or spark plug wire? I say that because it had trouble starting up right after winter. I kept the wires on the coil end but switched the wires on the spark plugs and it started right up. Is that indicative of anything? I have a "green monster" dual...

    Yup. Edited post to clarify. Intake was ever so slightly off but even after adjusting the problem continues.

    carburetor spitting fuel

    Well folks, all the above was done and the spitting continues. I blew air out the mix screw (air came out the pilot), reset the float height (it was off-level by about 1.5 MM on one side), checked the float for leaks (no air bubble when submerged), checked the float valve (clean and it sprung)...

    Thanks! I cleaned out the passages with air and cleaner but did not know where to look to see if things were going right (i.e. pilot inlet). Im also not sure I blocked all four of the little holes at once. Easy enough to go back through and check when im confirming float and heights.

    carburetor spitting fuel

    Oh yeah! That makes sense too. I can watch a cone of what i think is fuel coming out of the pilot hole. Also the clutch cable right behind the carb gets misted and wet. The other alternative is that the pilot hole is smoking, which looks like mist, and the back end of the carb is spraying the...

    Hmm easy enough to check. I did all that when i rebuilt the carbs but there is always room for human error. Especially for me.

    carburetor spitting fuel

    Well, I took it apart, and alternated carb cleaner and the air compressor in the relevant ports. The problem is still there. Either I've got something reeaaallly stuck in there or its another issue. Maybe its time to soak some parts? Im not sure. Insight welcomed.

    carburetor spitting fuel

    Thanks Gary, I'll check that out when I clean out the pilot circuit. Although, I did replace all the fuel lines last year. Unless they getting eaten away by cleaner/seafoam and depositing junk. I didnt see anything in the bowls when I looked this weekend, though. For anyone else with a similar...

    Thanks! I was having trouble sussing out what could have been blocked. The jet itself was clear. Back to the carb guide for cleaning, then.

    carburetor spitting fuel

    1967 xs650c with BS38s. I did a thorough rebuild and clean of the carbs before it went to bed this winter and I know the float heights are correct. Bike starts fine but idles rough on the left side. On idle, the left side pops and sputters and the headers are significantly less hot. Runs better...

    New exhaust, now bike smokes. Why?

    Special pod oil indeed. I think I remember seeing a carb thread with your specs in it. Its good to hear mine match yours.

    New exhaust, now bike smokes. Why?

    Update: did a compression test. PITA because the NAPA rental tester was broken (read 30psi on each side) so I had to pick up another one. 120psi on each cylinder. Seems a bit low but not too bad considering it was stone cold. Also, as recommended by @gggGary, re torqued the head. Seems like I...

    New exhaust, now bike smokes. Why?

    Unknown miles. And yes, the fancy plugs were what I bought it with. Im going with the simple ones. I think a compression test is in order soon.

    New exhaust, now bike smokes. Why?

    I dont think it was blue. More greyish. It was night in a poorly light garage. Im trying again in the daylight to make sure. I know what you mean about the plugs. Im not sure how they are working but they do. Ive been waiting to figure some other things out before i put fresh plugs in and...

    Oh? Thats a good tidbit. Valve seals I can replace.

    New exhaust, now bike smokes. Why?

    Yeah, Im a little worried about the plugs. Im still not sure why the smoke is worse with the new exhaust. It wasnt bad before. Well, not for a 40+ year old bike. Im crossing my fingers on valve guide/piston/ring issues. I reaaally dont want to have to do a top end rebuild. The bike was...
