Is that Motul 600 your running ?
Ive tried heaps of different oils, and 600 was the worst for almost fouling plugs everytime you start it cold.

It would start ok, but blow heaps of smoke and cough and run rough until it cleared. It would take about 500mt to come good. If would also start to foul just buy riding at light throttle too. I had to regularly wind it to redline to keep it clean. Fun, but annoying around the suburbs

Castrol TTS is much more consistant.

I dont know why the Motul 600 was so painfull.
