Hi,
afaik, the timing cant be adjusted.
only problem i ever had with mis-firing/backfiring (& even once the engine running backwards! ) was due to the woodruff key slot eing enlarged/worn, making the key loose & flywheel was spinning.
cheers,
GAZ |

Hey all. Thanks for replying and giving your suggestions.
I thought that I would report back.
After spending several days trying all kinds of variations to the carb set-up - well it had to be something to do with the carb right, as I had tried a different stator plate and a different CDI unit but with the same results - I put the bike back in the shed and that is where it stayed for the winter.
I got it back out last week and decided to have another look at the electrics. I decided to send the stator plate off to West Country Windings for a test. The test came back as a slight drop in output, but nothing significant. I was told that the wiring gets old it sometimes fails when it gets hot. To be fair the wiring did look a bit ripe, so agreed for it to be rewound. The plate was sent back next day, I fitted it - and - still backfiring
The last thing to try was the CDI unit - but reading about them is that they rarely fail and mostly never work incorrectly - and I had already tried another but to no avail.
Fitted a new CDI unit and hey presto, one running motorbike!!!!!
When I've got a minute I write a 'show and tell' on the rebuild of the bike.
Cheers. |
