    1980 xs650 running full and half choke

    Thanks, yes this motor is excessive. Bike sat for 8 years. Motor was not seized, but I still poured oil in the spark plug holes many times for many days to be on the safe side before starting. Yamalube is in the motor now. .003 and .006 right? When I was adjusting the cam chain before...

    1980 xs650 running full and half choke

    Here is a video of me starting the bike this morning after adjusting the idle screw. Think I may turn the mix screws in but happy with everything at the moment. Really think it needs a bigger main jet too. Motor is loud, left side exhaust has white smoke, sometimes more than other times...

    1980 xs650 running full and half choke

    Ok I adjusted the throttle screw and bam that did the trick! Thanks so much! So much work has been done fiddling with this old bike, so happy I just had one more screw to turn hahahaha. Bike was running hooked up to a tractor battery. One kick start makes me happy. Left exhaust getting a...

    1980 xs650 running full and half choke

    I am going to have to triple check the floats. From all the reading I've done, these floats basically will delegate lean or rich mixtures. If I want to enrichen the mixture, I must adjust the floats. I love working on older things. I can't explain it but I enjoy spending my time doing...

    80 special won't start

    I just put new plugs in. Unless I ruined the plugs with all of this "tuning" I've been doing, they should be fine. Right now I just re-assembled everything and I'm running lean on the left side. Still running lean over-all. I have the screws 3 turns out. Floats at 27.3mm. All new jets...

    For anyone having the same issue, driving the needle jet is really simple. Remove the jet and washer, then re-install the jet. You'll notice why. Then with anything you would like to use to drive it upwards (hopefully you have the diaphram and needle removed) I used pb blaster and carb...

    80 special won't start

    I didn't think what I was doing through. I've been very diligent with what I've touched. I never removed the needle jets. I think I turned the motor over backwards a few times and that junked up my carbs, this was after I had the bike running pretty solid. After that, it ran piss poor and I...

    right side pod filter was nearly on fire too, was this because of bad valve adjustment? I'm so confused. This bike did a total 180 out of no where.

    Bike only runs with choke on.

    right side pod filter was nearly on fire too. Could this be from a bad valve adjustment?

    Installed the new screws, bike starts with a little throttle but only runs full open choke. moving the screws really doesn't do much at all. I tried at 3 turns out and 2.5 turns out. Thinking I may need to do 4 but I also think the problem lies somewhere else. I'm not getting the fuel. as...

    I am still nervous about the white hot smoke. Regardless, I think it's my mix screws / o-rings and maybe the spring lost tension over the 8 years it sat. Who knows.
