I was told by the previous owner that my quadracer has a yz250 piston in it.

Has anyone ever heard of this before?

What is the advantage/reason for this?

Thanks.

 

never heard of that before, i belive that a yz and a lt are diffenent bore, and stroke, i know that a late 80s rm cyclinder, and piston will fit the lts, but not a yammi.

 

i think it was on FTZ's website i saw they do that...i know it can be done though. www.ftzracing.com i think.

 

Thanks for the tip. It appears that use of the yz250 piston eliminates the suzuki wristpin thrust washers that I've heard some complaints about.

 

well do me favor post something if thats the case cuz i wont put suzuki piston in seeings thrust washer just cost me 800 bux

And they describe why it is used, what they do to make it fit, and how much it costs.

I was told LRD built my motor and it has their logo and a number scribed in it so they must do the yz piston thing also. I haven't contacted them about it yet but someday I will need to do a top end and will have to figure out what parts I need.
