Bike: 999R / 998 Bayliss

I fitted the belts.

Before taking it apart the general concensus was that I did not tighten the belt tensioner pulley properly when I changed the belts. (Ducati Master Technician helped me to take the thing apart)
Big surprise, everything was exactly as it should have been.
Pulleys were torqued as per spec and were still good when we opened it up.
belts were tensioned correctly
The timing marks on both the horisontal and vertical cylinders all alligned perfectly..... The cuase of the failure could not have been the belts.

Before the failure, the bike started first time. It idled perfectly. No backfire. Linear power throughout the rpm range. No stuttering or stalling. It picked up nicely when accelerating from one gear too low. The only difference too that bike was that I removed the intake restrictors, which gave it a louder intake growl. That is it.

I am currently looking at the cost of replacement head, conrods, piston, valves, rollers etc. ooouch!!!
