Re: electronic ignition... no spark

^ ... that photo is very similar to a number that I've come across, with one just coming to me to sort out a misfire. The pickup and LT coil actually both read ok but both low figures, as is typical of the Indian aftermarket items, so I took the opportunity to swap both items out and rectify the an...

Re: electronic ignition... no spark

P One thing that I've come across a number of times recently is the splaying of laminates on aftermarket stator bases, where the laminates splay and cause the face of the pickup to angle away from the flywheel face, with the top trigger moving quite a distance back from the flywheel. Its a shame as...

Re: Pickup /flywheel alignment madness

great 17 is is then, Thanks for your advice guys and the image is very helpful too. If I spin my flywheel with a drill and socket adaptor I should be able to time the ignition without the need to start and run the engine. I read on MB about a neat mod using a tank strap trunnion to make an adjustab...

Re: electronic ignition... no spark

thank you Steve. It certainly has been a long trial. I'm sure that if you buy a complete electronic kit from one supplier that all the components would work well with each other but I could only afford to buy cheap single parts from various suppliers and had some problems, Who would have thought tha...

Re: electronic ignition... no spark

I'm glad you (seem) to have resolved the issue. But those magnets are usually fixed with epoxy glue and a screw, for very good reason. Plus you have now moved them closer to all the coils, running a risk of fouling. You could have just gently bent the fingers up, they will take a gentle tweak. I wo...

Re: electronic ignition... no spark

Re: electronic ignition... no spark

I read online last night that some flywheels have positive /negative pickup triggers and some have negative /positive depending on where the magnets are positioned. Where did you read that, as I've never heard that before?? I believe there are problems with alignment/ misfiring on the AF lightweigh...
