Had a crash with my 700 and after inspection noticed allot of dirt around the carb. when it hit the ground I was able to shut it down within 20-30sec but the motor does not seem to have as much compression.
I opened up the back plate and there was gray oil every where and I could see the dirt still in the crank shaft. looking through the exhaust port everything looks good no scratches on the side of the piston, cylinder looks clean. Should I tear it down or just give it a good flushing and hope for the best.
Damn I just got this beautiful HZ broken in to.

I would tear down and give a her a good cleaning. Minimize the chances for something worst like ending up with a big paper weight.

Tear it down and clean it up carefully. Grey oil can mean you are grinding up aluminum. I'd probably disassemble it entirely, drop it in the anti-freeze crockpot and rebuild it properly then you'll have a completely known and reliable quantity again.

drop it in the anti-freeze crockpot

I don't see the point of putting any engine or muffler in anti-freeze. You can clean an engine or muffler without using anti-freeze.

Maybe so but it's effortless when you drop them in the crockpot. They come out clean as can be. If you have never tried it, I urge you to do so when you have an opportunity. I pooh-poohed the idea until I tried it. I was instantly sold on it.

does the antifreez and crockpot hurt the aluminum?
does it also hurt the anodizing?

i want to try this on a few other stuff.

It does not harm the aluminum. It does an incredible job of cleaning everything else off of it. I cant say for certain about anodizing. You want to remove any rubber parts so the carb itself doesnt get dunked. I didnt come up with this idea. Many people will chime in and admit they use this process. It works beyond what you would imagine it would. I definately went from a skeptic to a believer.

Just do it on low and don't leave it too long. On high it does darken the alum. I leave it in about 4 hrs. I left one engine in for over 24hrs and the alum did darken. Does a great job though!

Dirty HZ
Well I tore it down and there was a grayish thick oil everywhere.
It looks like it just polished everything up, no piston marks cylinder has lost some cross hatch and the ring looks silver not black. this concerns me most,wish there was a way to measure it.

I am thinking maybe I can just get a new ring and maybe hone the cylinder a little and give it a go and hope it will seat again.

Or just run it as is since it is realy broke in now, maybe it will run like great???
