Hi Speedshop, My mechanic did mention that you needed specialist equipment to test the CDi. But was not able to give me any prices. Can you give me an idea of the costs involved please. I think you can PM me on this forum, if not you can email me. Thanks Lisa

Hi Tony, thanks very much for that info. I will pass it on to the shop in the morning and see what happens from there. Lisa

Hi everyone. I purchased this bike for my son, prior to him taking his test, for some road practice. However it was running fine (well as fine as these bikes do) He parked it up, when he went to start it again - there was no spark. Tried a few various things, changed spark plug, checked kill switch wasn't stuck, bump start - nothing. We then handed it to our local mechanic. He checked the same as us, most of the connections were starting to corrode and they have cleaned them up No actual breaks in wiring. But he cannot find the correct OHMS readings for the Pick Up Coil and also the CDi unit. So still no spark. Any suggestions/or OHMS readings would be very much appreciated. Thanks everyone

Hi everyone. As per most people, I only seem to stumble upon these forums when things go wrong. But I know you get some great brains helping out on forums such as this. My sons bike has just conked out and our local mechanic is scratching his head. Hence my search for good advice. I will post the problem in the relevant section rather than starting it here. But as the main person that deals with all this stuff, I need some help\advice. By the way his bike is a Yamaha TW125

Muttey, did you ever get this sorted as I have the same problem. I cannot find the correct OHMS readings online anywhere to check against. But my problem seems the same as yours. No spark. We are going to try and get another coil, wire it up and see if it sparks, but any help would be great.
