I finally got the mk1 finished (apart from tyres) a couple of weeks ago. I rode it up and down the drive at the back of the house and all was good. Easy starting, nice even tick over, good acceleration etc. I left it for a couple of weeks until I could get the tyres. So, new tyres arrive and are fitted, go to start the bike, and it`s running like a bag `o` shite!
It seems to be running ok on the left pot but intermittent on the right. I had the plugs out to check for a spark and it didn`t seem to be firing at all on the right. Changed the plug and woohoo got a spark. put the plugs back in and crap running returned.
It`ll start with choke but the merest whiff of throttle and it cuts unless you catch it just so and then it`ll rev, but you have to absolutely rev the balls off it to keep it going. The fuel was freshly bought when I put it in about 3 weeks back so I wouldn`t have thought that an issue but it is already looking a bit yellow but no rank smell.
Do you think that the firing issue is down to HT leads? I have checked it in a dark garage and I can`t see anything arcing out anywhere.
Any pointers from the oracles out there would be gratefully received./
