WTF?? three torched pistons

[rjt500r]

Using a timing light after the first piston failure would have instantly found the problem and prevented the audible hole drilling detonation on the 2nd and 3rd piston.

Yes it would have, I was thinking fuel not spark. What is it i am not hearing?? I did not hear pinging or knocking from this motor.

All you have to do is swap an XL200 motor in and you're all set!

Haha! Wise a$$i love it! Glad you got it figured out OP.

Glad i could provide some comic relief! feels like i have been taken out behind the wood shed about a dozen times this week!

Props to rsss396 you nailed it early on.

mx250r91 your post prompted me to do what i should have done from the start, verify the cdi was indeed a 250r unit. Thanks

Thanks to Jerry Hall who spent quite a bit of time with me on the phone yesterday, it's pretty amazing how quickly what you think you know, turns into, you really don't know after talking to someone with the knowledge and experience Jerry has. I thank you good sir, i appreciate your time!

first page i said to look into cdi. since there isnt much else that could burn a hole it only made sense  :nose-pick:

I didn't mean anything negative by my last post at all, just being a tard trying to lighten up the mood. I was really curious what it ended up being, glad you found it.  It would have taken several pistons for myself as well I'm sure.

No worries, i did not take anything personal from any reply on here. You put yourself out there on a public forum you will take some heat regardless. The end result is what's important with all the input the issue has been resolved.

If we was only as smart as you Jerry. You got a 800 number we can just call you when we have problems.

i dont want credit for anything.    the only thing that made sense was spark timing problem. im sure airleak would of just seized up the piston walls

Some funny stuff in this thread for sure. I'm glad you finally figured it out. Sounds like an expensive and frustrating time you've had.
