Hi

I suffered a terminal engine failure on my '97 748 Bip in Mid Wales yesterday. This happened at fairly low revs (about 4k), and the engine was still running on one cylinder. The bike was recovered home.

When I got the bike home I removed the front cylinder cambelt cover to find that the belt idler pulley had failed. The stud holding it on had sheared in the head at the top of the thread (overtightened by someone no doubt?). The pulley had embedded itself in the cover. The belt was still engaged on both cam pulleys, and looked to be still driving the cams, but of course very slack.

Has anyone else had this happen; is it a common problem? Also any ideas on what carnage I am likeley to find inside?
