Long time ago I removed the crazy unfused electrical feed from the post on the start motor to the ignition that the whole bikes runs off. AFter a fire on the LeMans I decided no chance on the Mille and instead routed main power directly through the fusebox before its trip off to the ignition switch.
The question is should I do the same for the Saprisa. The Sparisa has three cables, two go off to the reg/rectifier and other goes straight to the pos on the battery and is completely unfused. Should this be fused and if so, to what value?

What’s a suprisa?

If you are talking about the cable/wire that runs between the rectifier and battery it is very short and shouldn't be a problem. If you decide to fuse it a 20 amp fuse should be sufficient. The alternator output is 14 amps. I have a digital ammeter on mine and have never seen it over about 9 amps. At idle the voltage will drop to battery voltage very quickly, at long stops I like to keep the revs up a bit to keep the charge up.

I use the first as described and the second only to monitor amperage. They are tucked away in the fairing on one of the support brackets.
