Parts fiche shows all year Versys pistons the same part # as
06+07 had different part #
This is off KMC web site.
My quick look up off the online parts fiche I use most often show
only current 13001-0087 piston for all years and models.
sure your right, one of those quick posts from top of my head. Also meant "Stock V" little in it in case not clear?
But it could be because now superseeded online?, see post I did a year or two ago.
I cant believe it makes econmic sense to change the head when pistons are the obvious route, or gasket, but I lost interest at that point. Next time I;l remove layer from head/no base/ to set squish/bump comp.
"Appeared to confirm the part numbers I looked up as being different, as could see a 60 and 87 stamped on the pistons but - turns out a red herring as looking at later part numbers, has in fact been superseeded and now are the same!
Having measured the pistons at carefully every point, thats doesnt suprise me now!

the heads are different but they check out in the measurments we did over the phone. Noting the Er6 changes itself so you can never be sure excatly what the part number relates to? i.e colour
110080107 HEAD-COMP-CYLINDER V 2007
110080107 HEAD-COMP-CYLINDER v 2009
110080089 HEAD-COMP-CYLINDER ER6 2006
110080182 HEAD-COMP-CYLINDER ER6 2009
the dynamic CR is interesting, but given the Er6 inlet cams close later, in practise the DCR should be lower than the Versys.
Cam chains are the same, if head gasket thinner? Would have expected the chain to be at different points (as timing marks - between rivets - procedure is the same)
am surprised its not pistons though, the easiest and cheapest method, as thinner head gasket is less relaible method for a volume manufacter."
