i have got a 03 z400, i have got a worn out cylinder that i was going to send to la sleeve to have a sleeve installed. Do they do good work? What is there turn around time? should i go with the 440 or stock bore, i am also having my head ported, installing hot cams an a rev box. I will be racing the quad in mx.

thanks

 

I hear they do great work, 3 week turn around.

 

There a good company... I have had one problem... with my 2 stroke 125 i had them resleve it and stuff and they sent me the wrong piston... like it didnt have the oil ports or something so after i fried my piston i honed it out and they sent me a new piston for free and its ran like a champ ever since!

 

they have been around for a long time
