  2. CB200T Oil seal removal from points base

    Engine Discussion
    Could anyone help me with getting a stubborn oil seal out of the points base (CB200T)? I’ve bunged it up with some pliers already so there’s no turning back. I’ve got a new one on hand. There seems to be metal under the rubber portion. I just want to make sure it’s ok to be grabbing this as part...
  3. Points advancer — replace, lube, or leave it?

    Electrical Discussion
    I’m trying to remedy my CL360’s racing idle. One consideration is whether my points advancer (spark advancer) is worn out or malfunctioning. What should I be looking for when I inspect? When I pulled off the points plate, it appeared dry with a tiny bit of surface rust. Does it need some kind of...
  4. XL350 Timing Issues

    Electrical Issues
    Hi all, This is a single cylinder bike, but the ignition is pretty much the same as the one on my CL350 so I'm asking about this problem here. I recently picked up a 1978 Honda XL350 for $800. It wasn't running when I got it, but I recently rebuilt a CL350 so I figured this wouldn't be an...
  5. Points Sparking + Weak Spark to Plug 1971 CB350

    Electrical Discussion
    Hello, I just picked up a beautiful '71 CB350 and was riding around fine until suddenly I lost power, like the bike was running on just one cylinder. Lo and behold, I pulled the plugs, grounded them to the engine and turned her over: no spark to the right plug. Opened up the left side points...
  6. SL350k0 Started Running Poorly today - Mid RPMs

    Miscellaneous Discussion
    This morning on my way to work my SL350 started running very poorly at mid RPMs. It idles fine, and runs great (like it always has) above 5000 RPM. Under 5k (and above 2-3k or so) the engine sputters and chokes, and sometimes only runs on 1 cylinder. With the bike in neutral, just revving the...
  7. points power problem

    Electrical Discussion
    I am having a problem with the ignition section of the wiring. Bike is an SL350 k-2, new points, condensor, and coils. When testing for power in the order of connecting the wiring power to coil is good, connections to coil/condensor is good, but when connecting the two point wires one side...

    Fuel Supply and Carburation
    Hello Ladies and Gents. I haven't been around the forum for some time since selling "Herbie" the 1980 CM200 a while back to a friend. I've since had an SL350 land on my lap and I'm working on getting it running and could really use some help. Here's the scoop. I drained the gas tank and...
  9. Ignition timing problems

    Electrical Discussion
    Hey, So this may turn out to be a stupid question and I was just making a simple mistake but, I am having problems with setting the points on my '73 cb350. I am used a feeler gauge to get the points get the timing generally correct, and now I am using a test light to get the timing perfect...
  10. Parasitic Draw / Short at points

    Electrical Discussion
    Hello Honda Twins, I want to preface my first post with a disclaimer - I'm 18 and the only mechanically inclined one in my family - so troubleshooting this build has only been me, my climber manual, and the internet. Forgive my ignorance. The previous owner of this bike had cafe racer goals but...
  11. Points Grounding on Cover

    Electrical Discussion
    Still new to the forum. And to these bikes. I have a k0 cl350 that I have been working on for the past year and a half. I am close to being able to ride it, but I keep running into little problems that keeps me from being able to move forward. I don't think this bike has run in the past 30...
  12. Adjusting points - test light not on

    Engine Discussion
    Hey, I'm going through a tune up of a used 1970 CB350 that I bought and when I got to adjusting the points the test light I have doesn't turn on when the point gap exists. I've attached the light to the terminal of the left point and no matter where on the bike (engine, frame...) the light...

    Hello there! I'm having some trouble with my bike. It was running fine and then one day she just dies on me. Its a 1973 Cb350 project that I brought with a rebuilt engine but the bike was in pieces. So I put the bike together, I had a custom wiring harness that I made out of the original, the...

  15. Should both points have power?

    Electrical Issues
    I have no spark on the left cylinder. I have replaced points, condenser, and coils. I have noticed that while one set of points has power when the ignition is "on", the other doesn't have power. Should both of them have power? Thanks for any help you might be able to offer.
  16. CB350 Broken Spark Advancer Pin

    Engine Discussion
    Hey all, My engine hadn't been running very well recently, so I decided to clean up the points. In doing so, I also replaced the beat up screws used to lock the points down with metric hex bolts. I tried to kick start the bike, and there was an incredible resistance. It turns out that replacing...
  17. Lubing points?

    Electrical Discussion
    So I finally got my 1970 CB350 running but it was revving really high out of control randomly and I had to use the choke to bring the rpm's back down. I did some research and found out it was probably the lack of points lubricant. I ordered some Mallory distributor lube and didn't know exactly...
  18. Honda SL 350 Points to Electrical Ignition

    Electrical Discussion
    Hey guys and gals, My point to point system has been giving me some issues lately and I'd like to switch the bike over to an electrical electronic ignition. I want to get an idea of how difficult of a project it would be to do myself. I've got very limited mechanical experience but I'd like...
  19. Left point always on, right point won't turn on?

    Electrical Discussion
    So I've been teaching myself about my 1970 CB350. There's no spark on the left cylinder. I first checked the points using a multimeter and found they were good, so I went to the points next. Using a test light I clipped it to the right point and grounded the other side. The light never came on...
  20. cb350 suddenly running on one cylinder below 3000rpm

    Electrical Discussion
    Hey all, I've been riding all month, and have had no big problems, aside from a few oil leaks from under-tightened bolts, until today. Last night, as I put my bike in my garage, I plugged in a battery tender (still haven't done the regulator/rectifier upgrade), but accidentally left the kill...
