@Calum said: You can measure the coil to see if it's within tolerance, what I was finding was that from cold it would work a treat, but once under load and warmed up, it would fail to fire above 4k RPM. Okay good to know. So even my measurements looks okay to me I thought about that it might not be okay under load anymore. But I didn't want to manipulate any plugs just to measure under load. @Calum said: I've had this before with a faulty ignition coil. These can still be bought brand new from Yamaha and I highly recommend going for genuine coil over an aftermarket one. The aftermarket one I had led me on a wild goose chase trying to figure out the intermittent faul Do you have any link or shop? Thanks

The mot guy put an advisory on my bike about the lights at tickover. Reckoned that the stator was buggered. I tried to explain to him but ‘he had one when younger’ and so was right

@ksk-04 That sounds like the right one... Check where the wires come out above the gear change lever. The magnetic pickup wires can become bare where they pass through the rubber... You should have a good strong bright continues spark when you give it a good kick over. Not just one or two weak sparks. Try getting an irridium plug for a stronger spark...

Put the Yamaha part number into Google / Ebay and try looking at various different countries around Europe (do this in settings).

@Calum Yeah checked the fuse at the battery. Don’t know if there are any others?

@Mike1992 well the issue was that one wire had broken and after one evening of riding and doing some wheelies my stator blew and now im looking for a new one
