September 30, 200916 yr just had 20 mins out riding with the new spark plug in, and so far so good....could a spark plug really cause the bike to do that? How good is good? I am fascinated by this video as it's very similar to my bike's problem ( the stator is currently/ha! being tested ). Any chance you can upload the new improved tick-over to you tube? Cheers, Wayne
September 30, 200916 yr Author there we go, seems pretty normal now? i keep expecting it to start going daft again lol! hope it dosent!
October 2, 200916 yr Author just found out that the bike had been ran on castrol R40 or A747.... ive just been told by a local motorbike shop that changing from that to a modern 2 stroke would of prob been the cause of the spark plug playing up and the dodgy running... is this correct? Edited October 2, 200916 yr by stushine
October 2, 200916 yr Castrol states that the R40 is not supposed to be mixed with any other oils. This could be a problem!
October 3, 200916 yr Author just had a full day out on it and no problems at all.... looks like it was definatly the plug...
October 4, 200916 yr Your vids were great, yet I have not experienced that as a plug problem, I think it may be more likely that you gave finally passed your old gas! Good is good still yet! Cheers,
January 16, 201115 yr just had a full day out on it and no problems at all.... looks like it was definatly the plug... Hi I just joined this site to see if I could find the answer to the same problem. I will try this cheers Blackie
January 16, 201115 yr Gday, just to help some others that may be having similar issues - the plug picture you showed us was fuel fouled - clean that plug up and it will do as a spare. The bike was running too rich - this was confirmed by you saying that it was OK when cold and no good at running temperature. The cause? Well, we may probably never know but it is a possibility that poor fuel/oil mix was the issue. Cheers, Stork
January 18, 201115 yr I had the same problem with mine. Turned out to be a tiny piece of swarf on the O ring on the airscrew. If its not completly airtight you will get exactly your symptoms. Take the airscrew completly out and VERY carefully check the O ring and the seat on the carb. It only takes a tiny foreign object. If in any doubt replace the O ring. I have also replaced the inline fuel filter on mine (2011 model) as the standard item appears to be not much cop. Check out any Kart store on Ebay for a replacement.
