nightrider Posted October 1, 2015 Posted October 1, 2015 So what the heck is the difference between the Pre-2001 and the Post-2001 pistons in the Blandit motors?The pistons and cylinders have different pt#'s but everything else is the same (crank, rods, pins, cylinder head).Most of the aftermarket head gaskets and piston rings stop at 2000.Everything i see on the interweb has all Blandits at the same claimed capacity (1157cc)What gives?Higher compression pistons?

nightrider Posted October 1, 2015 Author Posted October 1, 2015 Interesting, the rings are all the same part# Quote
fatblokeonbandit Posted October 1, 2015 Posted October 1, 2015 in 2000/2001 when the mark 2 came out they had modified pistons to improve the oil cooling. in some bikes the consumption was deemed excesive, so there was a mod to the pistons, the later ones after vin 22102179, were fited with differant pistons, the older ones ars no longer available Quote
nightrider Posted October 1, 2015 Author Posted October 1, 2015 Ohh ok, thank you. That clears it up.Cometic lists head gaskets for only the pre-2001. I'm guessing they work for mark 2 also then. Quote
fatblokeonbandit Posted October 2, 2015 Posted October 2, 2015 the part numbers for the mark 1 and 2 head gaskets are differant but ive used a mark 1 head on a mark 2 engine with no problems so should be fine 1 Quote
rdubandit Posted October 3, 2015 Posted October 3, 2015 Yup, oil return holes had too larger over lap with the ring recesses and oil got burned!! I have a set of the "bad" pistons. I'd like to have a set of the newer pistons to measure the difference in the oil return hole diameter. Quote
nightrider Posted October 3, 2015 Author Posted October 3, 2015 I have both an 01 and a 99 Blandit engine.When I get them torn apart I will compare and post the measurements 2 Quote
