jbooker82 Posted April 30, 2007 Report Share Posted April 30, 2007 I will be running 66mm blaster pistons, with a 4 mill long rod crank at 400cc. Had the cylinders resleeved starting out at 66mm and can go all the way up to 68mm wich is 420cc. Quote Link to comment Share on other sites More sharing options...
dajogejr Posted April 30, 2007 Report Share Posted April 30, 2007 Look for a Vito's monoblock 404 cylinder used in good shape. By the time you resleeve and port your OEM cylinders...you could probably bolt on a Vito's motor for about the same.. What is your budget? And where do you ride?

badassbanshee479 Posted April 30, 2007 Report Share Posted April 30, 2007 be careful with stock cylinders with a big bore kit in them. The sleeve that is installed to make the big bore kit cuts the transfers way down and its hard to make power with them without a bunch of porting! I had a tyson 404 kit on my bike for a little bit and I was not happy with it. Made good power, but was not enough for me! Quote Link to comment Share on other sites More sharing options...

Yea your pobably right. I just happen to come across a pair of 4mill ported cylinders that needed resleeved. They were ported by patriot racing. I sent them back to him and figured might as well have bigger sleeves installed since they were getting resleeved any way. I only got about 400 in the cylinders. I wouldnt have done it if the cylinders were not alread ported for the 4 mill crank. Quote Link to comment Share on other sites More sharing options...
