blew up my '00 srx last winter getting ready to fix

update

here are some pics of the other 2 piston look good to me I'd call it rich if anything cylinders look good still noticeable crosshatch

carb was definitely clean and set to stock specs

fuel was shell premium and there was no pings or knocks sled ran strong right up until it quit

I have to find a bolt to pull the clutch I can see if the seal has ant noticeable signs of deterioratio doubt it but you never know

engine was always warmed up properly an had premium fuel and Klotz oil

only had 4400 mi

could probably get by with a complete bottom end, 1 cylinder and head or a complete engine if anyone has one or knows about a smashed up sled with a good engine let me know

this is more what I'm used to seeing from lean issues

but I will look at the seal closely and look at the carb again though I checked the carb as soon as it happened that was my first thought

reed I couldn't verify either way because its part of the carnage I'd have to guess that something went bad underneath like YG said upper bearing or maybe a broken skirt maybe the rod broke first

I can't explain all of the damage to the crown though without heat unless maybe something came loose and the piston slammed the head a few times

IDK any ideas or a line on parts please let me know and all of the help already is greatly appreciated thank you

Got her back runnin lots job weld jk

Fingers crossed now sounds like its running good need a low oil sensor if anyone has one lying around
 
Bobcat,
That was running extreemly lean if you ask me. I had that situation on a Cat that I had to rebuild. Problem was caused by a ripped carb boot. Your mixture happens before it goes through the boots into the engine. If your boots are ripped you lean out the mixture and run lean. I would check your boots on all cylinders before you run it, for fear you may have the same issue.

Thank you I will keep a close eye on everything I put a new boot on so hopefully it will be ok

I have been warming it up the last few days and noticed the pro pipe doesn't warm up as quickly as the other 2 and when I pull the plugs more vapor escapes through that plug hole than the others

Also what is the break in procedure I put some premix in it and fire it up every day for about 10 minutes softly revving it then if I ever get snow I'll fill it with premix and baby it for a tankful
 
I only put a gallon or two of premix at the most. Onve oil injection is up and running your double oiling. Double oil = lower octane which aint good either.
