The Big engine failure thread
Those of you who have experienced engine failure what happened?
Can you describe what happened to your engine.
What was it that broke?
and how much you rev your engine at the moment.
Was it because the connecting rods were too weak
or to a valve showed
Write it down so you get some data
and how you can tell which part is causing the crashes

Popped engine.... which one? LOL
Ive got 3 ash tray pistons at home. The 4th is still at the engine shop.
There is alot of different weak links to the SHO motor when your pushing BIG HP!
Best advice, get a knock box. Its next on my list of things to buy before hitting the water.

We have a 2009 FZR with Stage 1 only. $7k repairing cost.
I cant mention all the damaged parts, but the main ones were Drive Shaft, Rods, Cranck, Pistons, Sleeves, Head .....etc
We still dunno why this happened, but the problem started at the Drive Shaft first then moved to the rest of the engine ...

That definitely sounds like a user error because there are people I know of doing 100+ hrs on a stage 3 and 500+ on stock engine. I had a hefty repair bill with my ski. Valve floated and damaged the head, destroyed cams and damaged four of my valves. Should be getting new head this week and motor back up and running by next week
