Hi , Yes, looking at the water pump part of the clutch casing it looks to have made tiny holes in the metal. if you turn it over you shold be able to see really small holes where the pressurised water has entered the gearbox. If these are not visible then the water is getting into the gearbox through another entry point (seal). I am pretty sure i can see the holes in the case.
p.s. these are the best photos i have seen on here, its the only way to diagnose problems.
its hard to tell from the photos. look inside the case, the inside of the water pump as it were the other side where the water pump drives from. if you can see perforation here its a new case i'm afraid. I hav'nt done one for a while now but i think they came down in price, (
my 04 250 did the same, its either pilot jet too small (sorry cant remember the sizes) this will be worse this time of year due to the cold. (presuming you are in UK).
But i also used to de coke (polish the piston crown and the head) frequently, this always stopped the Ping on my bike as it is usually pre ignition.
it sounds like the main bearings, but you say there is damage to the piston? if bits have come off , they may be part of the problem in the bottom end. By the sounds of it its seized at some point. I does sound like a full engine strip.
How often does this recurring topic have to pop up before it gets 'pinned' at the top of the forum to save time? ...
Its a crying shame, every time a Beta breaks down the next post is about fantastic service from either the dealer or the importer, lets pin that to the top as well.
Still, the factory should have sorted this out by now.
its really difficult to diagnose carburation issues like this but i think your looking in the wrong area.
If the majority of bikes the same as yours run on the "base settings" then so should yours.
its bite the bullet time.
First check the ignition timing, doubtfull but its easy to do.
before going any further, re post and ask if there is some one willing to let you borrow a carb ( 10 mins anywhere should show up if there is an issue)
Next remove the reed block, are the reeds sitting down? if not try turning them over to see if that makes a difference before replacing.
make sure that when you replace the reed block it is in good condition and that its mating surface if clean and sealed (smear of silicon)
Failing that, and if it was my bike, i would strip down the top end and inspect the piston, long shot i know but youve got to start somwhere. while the top is off check for big end and main bearing play. if ok i would still REPLACE the crank oils seals.
new base gasket and rebuild the top end.
its a 2 stroke, thats covered the basics, its not a complicated engine just annoying.

Found them. Do you trail ride yours?
