Hey CycleWizard, How about clearing up some Thumper Myths, and offering Tips and Tricks that you have learned and keep in your arsenal? I know your first love is the RFVC Honda motor, but many things that we have discussed can work on many thumpers. I know you are making parts and offer motor and machine work, so pricing and offering those services may be best discussed in Vendors. Here, would you be so kind as to address high compression, cams, rods, valves, gearing, oils, oil pumps, cooling, big fins, head work and options, etc. etc? I see you are posting in several threads, but thought it may be GREAT to have a one stop for the masses to refer to. Your knowledge is impressive to me and I learn something with every conversation we have and post you make... Thanks in advance!
