Judge1 Posted September 23, 2010 Report Share Posted September 23, 2010 Good question! I have wondered about this myself. No one on this site ever talks about resleaving cylinders. Quote Link to comment Share on other sites More sharing options...

jbooker82 Posted September 23, 2010 Report Share Posted September 23, 2010 I had a pair of cylinders resleeved. I bought them dirt cheap with a patriot racing 4 mill drag port. It cost about as much as (actually a little cheaper) buying good nonported oem cylinders and having them ported. I had dan at patriot racing resleeve the cylinders. That way the sleeves are matched up correctly. Who knows the original port work better than the guy who originally done it. I would at least use a sight sponcer who speciallizes in banshee's over your local machine shop. The original porter would be best. I had big bore sleeves installed in mine. Why not gain some displacement while your at it. Some people will tell you big bore sleeves will choke the transfer ports due to there larger diameter. This is some what true depending on what sleeves you get. I had smaller big bore sleeves put in mine. The bore was 66mm to 68 or 68.5mm. I could see the larger 70 or 72mm big bore sleeves choking the transfers. The ones I had didn't go out to the head studs, and there was still aluminum against the sleeves in the transfer ports.

crash&burn Posted September 24, 2010 Author Report Share Posted September 24, 2010 second question to the sleeving? i have noticed that there was big bore sleeves avablible is this possible for the stock cylinders or are they just for big bore cylinders Quote Link to comment Share on other sites More sharing options...
jbooker82 Posted September 24, 2010 Report Share Posted September 24, 2010 I had about 700 in the whole top end. Purchase price of the cylinders, sleeves, labor, finish bore and hone, blaster pistons, and a pair of blaster piston domes. All work was done by patriot racing.

jbooker82 Posted September 24, 2010 Report Share Posted September 24, 2010 Unless it specifies that they are for an aftermarkert cylinder then they should be for oem yamaha cylinders. You can get some called heavy duity. Those start out at 64mm and go all the way to 68 or 68.5mm. I think that is what was installed in mine. Then they just bored them out to 66mm.

jbooker82 Posted September 24, 2010 Report Share Posted September 24, 2010 Same cylinders before the resleeve. Notice the difference between the iron sleeve and the cylinder head stud holes. Quote Link to comment Share on other sites More sharing options...
