SXR sxr big bore sleeves , 3 mll stroker

833cc

stock sleeves go to 85.4mm pistons. I ran a 77mm stroke with 84mm pistons - awesome power.

Any aftermarket sleeve company nwsleeeve.com or advanced will have sleeves that are replacmenets and they will go 85.4mm no problems.

I dont like going over about 84.5mm bore on OEM sleeves when ported and stroked. They are just too thin but aftermarket sleeves are much stronger.
 
Hi. Could you guys please tell me where you got your rods for stroking from?? What brand pistons are using?? Thanks

OEM rods or billet RADS (long out of business)

If your OEM rods are bad suggest looking into ADR Aaron Davis Racing - He makes stroker cranks (YAM) and sells Rods.

Pistons sub 83mm always OEM plus 83 WISECO (OEM not available)
