View Full Version : Maximum amperage draw?

What is the maximum amperage draw that you can put on one of these engine's electrical systems? I want to order a fan soon, but it seems like they go from 5 amps and 700 cfm to 1500 cfm and 13 amps. How much more than 13 amps can you draw? I won't need much for lighting, probably 10 more amps, but that seems like it will be too much.

The manual for the bike ( motor) should tell you.
Check the size of the fuse to start with , some ecu have a relay inside them and you may have to run a *anew relay if you want to go higher that the normal usage ( fuse).

I think 30 amps total is the max, at least for my 955i

I looked in the service manual. Says 375 watts at 5000 rpm. A lot more than I suspected.

The fan and lights will be outside of the stock electronics so I don't have a problem with them. Also, for reference this is for a 750 gsxr. The 600 and 1000 are probably the same.
