2003 Bullet 500 4 speed kick start
Engine started to miss occasionally on a 40-minute ride, especially when accelerating. This became progressively worse. Initial thought was fuel supply, so cleaned carb, tank, checked fuel tap. No difference. Next thought was electrics so (progressively over 2 week period) replaced spark plug, installed new points and condenser, new H/T lead, plugged in new ignition coil - no difference. Probably the carb afterall, so replaced the current carb (VM28) with an Amal; no difference. Engine will start but cut out and start missing and farting when opening up. Ignition timing was double checked and tried also slightly advancing/ retarding. No luck here. All connectors seem to be okay and I have spark on the plug.
I now have to wait until this corona lock down finishes and I can take it to a real mechanic who knows how to work mukltimeters etc and takes a step by step approach but if you have any suggestions in the meantime....? Cheers. Clement
