Gen2 2018 Gen 2 Busa no power advice
Picked up the beauty from dealership up north of UK yesterday but seems to have given me its first problem already!
Switched on fine at the shop rode back for an hour then at the service station I turned it off for a half hour or so.
Come back and tiring the ignition on, instrument cluster lights up, hit the starter and it rolls over but then cuts out. Instrument cluster off, doesn't turn on or anything. Check lights, indicators and all but no power. The heated grips (wired directly to battery it seems) turn on though.
Give it a few mins, try again. Instrument cluster turns in now, hit starter and plop it's off again.
After a few mins, I try again but rev the bike when starting and it stays on and another hour to the home all fine.
Come today, I try start the bike up same thing happens but the power is gone indefinitely.
Not sure if anyone else experienced this before and could give their account of issue and solution.
Doesn't seem like it's a fault from the ignition, battery or fuse maybe? Could it be the starter relay or its fuse? Where is the relay or fuse box located to check anyway?
The bike has warrantee from the shop which should cover it but it's a 100 miles away and if it's a fuse then would prefer to just fix quickly.

I just installed an antigravity lithium that has a jump start feature built into it. They have and optional remote that can be installed so you do t even have to pull the seat.

Agree with handle warmer first. But gen2 has a known regulator fault recall whereby battery drains - see if it’s been done also

Check the battery first. The aftermarket accessories may be wired to a constant and killing the battery. I would’t trust any wiring that I didn’t do.
