Anybody know the cc displacement on the HM100 motor? This is the engine on my Heald Super Bronc. I thought I had this info written down somewhere but can't find it now. [The mind is the first to go and I cannot remember what the second thing is!] I did find other ID numbers on this motor but do not know how to decipher the codes. Do these numbers tell us anything about manufacture date, etc...? Last question: US Forest Service and Bureau of Land Management out here in the Western US often require that ATVs be registered and tagged by the State Motor Vehicle Division. I will chk with my local MVD office to see what, if anything, I need to do but these Healds were not Titled in any way were they? Thanks for any info you can provide in my quest to learn about these minibikes.
