basic kit is like $149.99 i upgraded it to the mega system for better more feathered type flames & have approx $500 in the total system....... no that i know how to do it would prob only take a few hours to install...... a lot of it is trial & error witht eh mega system as you have to get the ignighter pointed just right for the flames to get 3-4 foot.
doesnt make any of the rear fender, rear foot peg or anything back there hot to the touch......
mighty mouse,,,,,,,, my buddy just put his kit on a yamaha stryker with cobra swepts on it (have to take baffles out 1st though) looks real good too as his flames dance across the ground where mine go up in air.
ya have to drill a small hole for spark plug,,,,,,, & the original kit you are correct,,,, it ignites up unburnt gas.... however it only did a small blue flam about 2 ft long (kinda like an afterburner on a jet) i wanted the more feathered type flames so i then went to the mega kit & installed a secondary fuel pump that is right before the plug & gives ya about a 3-5ft flame......
then have it all set up with seperate key switch to active it then a push button to *light em up*
have to give props to another Fury owner that i saw them on.......LittleMantc
he helped me alot in fine tuning it to get it just right.
