Hey Marcel
I’ll do a resistance check in the stator tomorrow with the bike fully warmed up.
- Battery is a yuasa ytx 14 BS, not sure on age. Haven’t had it checked either but will get it done at halfords asap
- Headlights are stock bulbs a year old as I replaced them not long after I got the bike
- There are no electrical accessories on the bike at all
- Yes the bike does misfire/jerk occasionally whilst riding, mainly when changing gear, I’ve I pull clutch in, shift up or down and it takes a moment for the bike To respond and can jerk/misfire.
The Regulator/rectifier that blew is already the uprated one from your shop. I’ve had to revert to the OEM one that luckily I kept.
Other things to note. On the uprated regulator the bottom end performance of the bike was much better but top end lacking. Putting the OEM one back on yesterday I noticed a much flatter bottom end but top end power improved.
Also to note. When riding, if I put the headlights on when I’m cruising at say 7k RPM the tacho will do a little jump when switching the lights on. Doesn’t do it all the time but enough to make me question if there’s some voltage leaking somewhere.
Sorry for the essay. I just want to get my machine working properly. It’s my only means of transport, but if it keeps blowing brand new parts I may have to get rid, which I don’t really want to do.
