Why do bad things happen to good motorcycles?
My Dommie has done about 40-45000 miles, 20,000 of them across Africa.
Valve clearances were adjusted about 8000 miles ago.
Everything has been great until last week.
First I got the occasional misfire. Soon it got worse and would idle fine, then cut out as I applied the throttle.
Replaced spark plug and CDI.
Still misfiring. Seems to start when it gets warm. As I tried to ride it to a garage yesterday it was groaning and ticking (with spark frequency). Cutting out and no power. There's new oil in it and plenty of it! I took the oil filler cap off and there was some bizarre smoke (steam?!) curling out. Never seen that before...
Leaving it to cool allowed me to get it to the garage. The bike was not overheating according to the oil temp gauge - normal operating temp seems to be 220 f., yesterday only reached about 140 f.
Help appreciated, especially if it turns out to be something easy I can do myself....
