Very bad running.

<< < (5/7) > >>

TrickyMicky:
I had exactly the same problem a few years ago. It was not long after I had replaced the complete points back plate with a nice new fully fitted out pattern one. First failure was miles from home, the very nice RAC man was familiar with these bikes and diagnosed a faulty coil, and we travelled back home on his lorry.  New coils fitted, problem re-occured about a month later, so like you I removed the points cover and ran the engine and it looked like firework night.  Still had the original 1976 backplate which was re-fitted along with two sets of genuine(expensive) points. No more problems!
  PS the condensers are the original factory fittings, 47 years ago, the other problem with the pattern plate was difficulty in trying to get the correct timing for both sets of points. Try  and stick with originals if at all possible. Have fun. Mike.

Hi Mike, My backplate is original but not sure about the originality of my points or condensers. If you think genuine points are expensive try original condensers, David Silver is charging over £50 each original condenser!

Oddjob:
I have original points and condensers, all in genuine Honda packaging, however they ain’t cheap but cheaper than DS, let me know if you’re interested, try and problem solve it first though, I only want to sell if it fixes your problem not for them to sit in a drawer because it was something else.

Bradders:
Thank you Oddjob. I’m sure I have my original ones stored somewhere so will try them first. Thanks for the offer. Chris.

Bradders:
Evening all. Have finally changed my condensers , sadly with no improvement. Number 2 and 3 points are still arcing like mad. Any suggestions what I might try next?
