Well I've been surching around endlessly trying to find engines with quoted specs. They all seem much of a muchness! The CB engines seemed to be no better than the CG's on average. The exception being these suzuki/honda hybrid things. I talked with Mr Yang from FAI, he told me to go for a genuine Zongshen or Loncin which are superior quality to many other makes, he then pointed me at a genuine zong cg and explained that the Chinese cb engines do not offer the expected gains from pushrod layout because they are cammed/ported for chugging heavy loads away from constant stopping and at that they are never as good as a cg down low. Interesting comments.
I was all set on a water cooled zong cg from the same seller as the a/c one Mr yang showed me (it's a bit more pokey) then I stumbled upon another seller with one of these upgraded Haoyue/ty/suzuki/honda lumps. I don't know if they are the real deal or just bog standard ones though.
What do you make of this..........
