Solar charger used to work well on my old one. Just helps a little bit against the tracker draining the battery.
I always have to look it up. First time I did it I didn't do the right order, pedal felt awful.
3rd 4th and 5th are the gears that i pull really hard in, litterally change up just as i get to 7k may overspill a few times.
My issue currently is getting off the line and 1st to 2nd, im guilty of changing up too early in first, hence i drop revs circa 4k and have to wait a couple of 10ths for the powerband, i need to be brutal i think in first, hopefully not over revving, making a good gear change. That should give me a chance to break an 11.99
What oil did you use please?
