how big are you planning to go?
I haven't heard anything about them but you will have to check with them in regards to the port timing if its racing/freestyle... and the prices are per unit so your looking at a $600.00 set-up plus after you get your sleeves in you will need to get your cases fly-cut to accept the bigger sleeves, as for the pistons I think most guys run wiseco pistons.

Im looking to go at 771cc, y think it more reliable, you are in the rigth. they dont tell about if the port is for freestyle.
I check with them the port timing type.

Randy has his own sleeve design, MANUFACTURED by Northwest sleeve.
His part # is 1820, our X Scream sleeves are 1829, 18??, 18?? for the three we have northwest make for the X Scream billet engines, One of the older Dasa big sleeves are 1795 if I'm remembering right.
The only sleeves you can buy from Northwest that are NOT propitiatory are the BB 1588 and I think they have a replacement stock 760 sleeve.
