ECU flash done nothing and cannot see any water damage, wires look okay Haven’t taken the front wheel off and actually inspected the inside of the mechanism (<— don’t know what it’s called lol) as I don’t have a stand/lift and the bike is quite heavy, but if I have to I will see what I can do, I don’t get it as it was recently working then all of a sudden in high ish revs it would bounce about going from 50mph up too the 100’s gone through all the connections I can see and they seem to be fine also, does a wheel driven speedo have a sensor near the sprocket ? If so I will clean that, give me some suggestions before I have to Chuck even more money at it plz lol
