jostby its a 250 and a 2001

print the service manual and re-read roostafish' post. If you are positive the engine is seized and not just the kickstarter then there is nothinng else to do other than pull the top end. Then you will know for sure if it is a stuck piston or something in the bottom end.

Ok kinda a smallish update, I had pulled the exhaust off today to have a look at the piston see if i could see any damage that way

Heres a few pictures of what i could see, I did find very very small thin parts of metal also.

I can't even look. It has to be nearly sterile before I start to teat it down, particularly if it involves the engine. I would not do anything further till the engine andevrthing around it is spotless. Bits of metal indicate you will be doing at least a topend.

Sorry dont understand mate?

bike will be getting a full wash before anything is taking off.

I think PEB has the same concerns as I do....., put the pipe back on! Then remove the seat and tank. Pressure wash everything, you would be surprised at all the dirt and debris that get packed up under the tank and frame. This dirt and debris can fall into the lower end when taking off the top end..., this is not good!

Same here, my bike never sees a wrench in the garage before its spotless.

[W8TSON]

Yes i know its very dirty it will see a very good wash before any spanner work happends,

anyone shed some light on the piston?

[GMP]

You can't tell from those photos, only a small section of the piston is visible and that looks reasonably healthy. It could be seized on the intake side as well.

2001 model? Last year of the main bearing poor quality control. My bet siezed main bearings. My 2001 XC300 recently did the same thing, motor locked up tight. Pictures of exhaust port appear odd, what looks like dirt may just look that way from the camera and/or lighting. Pull the top end, then you will know for sure.
