I say read up on it and do it no worries, hardest thing is drilling your own jets to suit the smaller displacement and thats not hard at all, get number bits, get a small 12v battery to open the solenoids and run a wet kit with a 12v. fuel pump to shoot the extra fuel in. just do some research and have fun. I ran spray on a car for 30,000+ miles and never had an issue with it killing me or the motor, as I built and tuned it correctly etc etc.
hahahaha death and gloom! stick some wheelie bars on it and spray the house down. My bud runs a pro drag bike and has 4' swingarm and wheelie bars and sprays so hard he spun the center out of an alum rim while launching once!
