Well I HAVE DONE ABIT OF HOMEWORK ON THIS ONE and everyone I have spoken to has suggested the Zen 26 PUM.So I have today gone and bought one and DEFINETLY going to fit it to a Lawless and a pipe from Doms in South Africa.So for me its the ZEN 26
I will agree with winz we have had nothing but good runs out of our Zenoahs I am sure the sikk motor are good but for the money you can not the Zenoah 260.
