Moderator DirtyDT Posted January 6, 2013 Moderator Share Posted January 6, 2013 Providing the rebore has been done properly then I would say the coke isnt working too. I would also check the fuel line, fuel filter and clean the petrol tap. It sound like you are missing that initial squirt of fuel to get combustion without doing this manually. When the engine fires the fuel system gets a helpful suck to help it along. Link to comment Share on other sites More sharing options...

Moderator DirtyDT Posted January 6, 2013 Moderator Share Posted January 6, 2013 OK but the fuel still needs to get from the carb to the cylinder. With the coke on, the mix of fuel and air will be different but even with the choke off, the bike would still be doing its best to run. Have you cleaned out the carb especially the cold starting part of it? You may need to check/replace the starter set. LINKY Link to comment Share on other sites More sharing options...

LINKY just been out and messed about with it, took the choke plunger out put my finger over the hole it came out of, and it started first time, looks like it was the spring stopping the choke going on all the way, so ajusted the spring, put it back together and it starts first time... bloody thing, been messing with it for months, and it took 10 mins...
