I am installing one of these kits into my bike, and am a bit concerned that they dont use relays for the high current draw stuff , i.e. headlight , start solenoid and horn. The unit is sealed so if one of these functions shits itself, you need to buy a new kit and rewire the whole bike

 Has anyone on here used these kits and know if they will last the distance without relays ?

No idea, what is the advantage of this kit????

 This bike is a project-when I bought it it had no wiring to speak of , just ignition,headlight and tail/stoplight.

 I have installed the kit to give me a totally new wiring harness and also indicators, oil light , high/low beam , neutral light , etc.

They probably use transistoror SCR switching in lieu of relays which shouldn't be a problem

I used the ultima kit on my litech sportster easy to use havnt had any problems with, Im running a capacitor in place of the battery, joe hunt magneto and kick only, but I know a coupla other guys who run em with elec start and thay had no probz

 Cheers guys, I ended up fitting four relays. one for hi beam , one for low beam, one for the start solenoid and one for the horn.  May be overkill but WTF
