I too have the FTZ top end. I bought my current LT from a guy who sent it to them and it has the YZ piston, He had told me that they use the YZ piston and modify it for the LT. I can tell you that it does make considerably more power than the previous '92 quadracer that I had with just a port and polish job! I would recommend it to anyone looking for better performance.

 

My ex- girl friend has that set-up,Vito's Performance did her's and it work's great,she's the champ at the home town Drag race's in the 250 class.The kit she has is the 300cc kit.

 

Well no wonder she's the champ...... With a 300 in the 250 class... Just kidding..

So Vito's does their own porting package with the YZ piston, or do they send it to FTZ?

 

Gee FTZLT250r sounds like you dont think a female can ride.

 

Nope, not at all. It just struck me as odd that she's running a 300 in the 250 class....

I checked out the Vito's Performance site and they make no mention of working on LT's......

 

Yeah I know,He used to work on them all,now he's not doing any engine's.You could ceck out www.macracing.com,they do Suzuki's,they're going to do my Zilla engine,they're going to cross-breed a few part's from a sea-doo motor and put them into my Zilla.
