Doug,
If you plan on running a blower, FI and nitro I would definitely invest in a special , bullet proof, carbon fiber, well padded, extra thick, form fitted seat and jock strap for your 100cc Honda. We built an injected nitro aircooled VW for the sand drags and during the teething process trying to start it we would literally blow a head off about every 5th start. One time right in my face. Scared the you know what out of me and burned my eyes. I could not see for about an hour but slow came back. WHEW! We used a special retard on the dist. for starting after that and once it was running cranked it up. Keep that in mind.
John
