Hi 

can anyone tell me if a dt250 piston will work ok in my ty250 twinshock?

I have had one fitted with a little removed from the corners of the skirt so should be fine

I got a spare barrel with a dt piston off flee bay for spares, I'm running a wossner at mo, but it's started with piston slap. So I was gonna try spare barrel & piston. 

If it was on a TY250 and it ran, it should run on yours, but you didn't actually say what the barrel had been used on previously

It was off a 78 ty250 , he said it ran ok but I won't know till I try it.
