f4i doesn't like to rev
hello lads, today my f4i tought it was a good idea to start messing with me.
problem: rev it above 8,000 and it cuts off. no matter if riding or not. it will not turn completely off but it goes down to 500rpm and then resumes idling and works completely fine again until you hit 8k+ rpm.
and then the strange part, with the lights + fan off (manual fan) it will sometimes rev happily to redline but not guaranteed.
lights + fan back on and same problem will never rev above 8k.
anyone know what it could be?
bike was working fine yesterday and the days before, this problem came out of nowhere.

I'm not particularly adept with electrical issues but I'd say to start with your rectifier and/or checking your ground wires. Here is a good overview on the charging system and how to test the components (it's on a RR, not a F4i, but close enough) - https://www.youtube.com/watch?v=H5ZU_c2a1pA
Hope that helps!

But as soon as i flick the fan on battery voltage drops to around 13.2

My new fairing set will arrive next week so I really would hope to get the bike running properly until then :/

Dang it bought a new battery today since the old one has been in the bike for ages however that didn't help at all either. Also when revving it to 8,000 it sounds now like a slow rev-limiter, battery voltage drops to 5-7volts for a millisecond everytime it bounces off the 8k 'rev limiter'
