dropped another piston.

[DezKnotz]

i have now dropped two rear pistons in less than 3 tanks of gas. what the *&$# is going on.

 

[newman]

holy lack of information!

What kind of failure? Ringland?

 

[DezKnotz]

i think that my crank is bad and messing up my timing because the pistons keep breaking up. i think.

 

[WFO Speedracer]

I can't hold her anymore Captian shes breaking up.

What has you guessing at the crank?

Some information you might provide would probably help tremendously.
You know, engine, setup, compression, gas octane, ignition setup, etc etc etc.

Right now you're basically saying that your ski is green and it doesn't run. What's wrong with it?
Except you didn't even give us the color.

What's wrong with it?

it's eating pistons. opworm:

 

[MADMAT]

I don't know whats going on but I can tell it $uck$!

New complete top end?

a new topend will probably eat another piston. he needs to diagnose his root problem.

I should've figured some rednecks here wouldn't be able to handle compound statements.
Both sentences should have been in quotes.

 

[Shonuff]

I guess we may be able to rule out the crappy Florida gas now.

What octane are you running and what is your compression? Are you detonating? This has not been a good 2008 for you, Mikey.

Bingo! :fing02:

 

[DezKnotz]

well heres what iam running. 701 with b pipe msd enhancer ada head rad fly wheel v force reeds reed spacer x metal water box, 94 octane. sorry for the lack of info before i rode the little bus to school.

What carbs? Jetting?

A little more info as to how/when it seized? Were you at WOT? At idle?
DId yu have to bore the cylinders after each failure? Did you hone the cylinders with new pistons? Ports chamfered?
As you can see there are a ton of questions to be answered (and thats just the tip of the iceberg) before anyone can help you out to why you are having issues. The more info the better. Or you could just keep throwing pistons at it and see if it will fix itself!!!!

 

[ChrisGooch]

maybe check your timing with the rad flywheel?

[DezKnotz]

i did bore the cylinder after the last one drooped. the motor never seized up on me it was after a nose stab. i gassed it to come out of the water and she just shook a lot and didn't go any where. then i checked the compression and the rear cylinder went on me again:bs2:

 

[Cross]

Do you have any pics of the damage?

 

[Big Kahuna]

hmmmmmmmm, water intrusion.

Maybe you have a air leak in that back cyl. I had an engine once that had a minor air leak and it kept eating the rear cyl. Too much timing, small air leak, go lean, deto, and boom.

I was thinking the same, have you replaced your crank seals? I had one that was leaking and it nipped up the rear cylinder

 

[waxhead]

A pic of the piston would make it alot easier to actually figure out whats going on
