have an old Yamaha DT175 2 stroke dirt bike, was having a ride tody when it seized, back wheel locked up and kick start is now stuck and wont turnover, it had plenty of oil in it but when I drained it before itdidnt look flash, contaminated with something, i just dont know what, im assuming the only way forwrd from here is a rebuild! Or is the a chance of a cheap fix!

LMFAO, i had a DT175 do EXACTLY the same thing. Pull spark plug, fill cylinder with oil and leave for a week, then kick the crap outa it until all oil out of cylinder, put plug back in, bingo, free again.

Awesome, will, give it a whirl in the morning, that would be a great outcome, fingers crossed, would it be better to fill with oil or something else!

I used oil because i was 17 and that's what the old man had in the shed lol. Diesel may also work mate.

Well, this happened to me years ago, and when I pulled it down the piston was in 1,000 pieces.Hopefully you will be more lucky.

Yer woulda done some damage to the bore and piston.it doesn't cost too much for a rebore and new piston and rings. well mine didn't, but that was back in 1980. think mine was called a CT2,or CT175. Still got a set of clutch plates for it, brand new still in unopened bag.
