72 dt2 250 piston ???

I am new to ADRIDER...so hello!

My question is: I just picked up 72 dt2 250 and the thing runs good so far. I do have little piston slap and would like to just freshen it up...9k miles.
I can find pistons on fleabay with no problem but they all have just one piston ring slot and are factory Yamaha bits. The piston rings that I find all have two or more in the kits...factory Yamaha bits once again???? Can anyone help with this so I don't make a mistake and waist money?

Thanks much all.

DT 250 MX pistons had one ring, DT 250 Enduros had two. Not sure which one you have, but I ran an enduro piston in my MX. It took a little edge of the power band because it had a little longer skirts and helped some on the lower end. It still ran like a scalded dog and was managable in the woods.

I ran a 250 MX as a work bike close to 17 years i had the single ringed piston layout as discribed, i cant see it making any difference to your enduro i thought the DT250MX just had slightly diferent piston to lower compression a little from the enduro. I would risk buying one if i were in your possition, great bikes by the way mine was fantastic.

Thanx gents...I think I have all the answers I need. I will get on the endure form for giggles and some god info. The bike runs good for sitting for years and just needed some love but I want it to be a reliable driver so will press on with the freshening up.

Thanks again and will talk soon.
