So I've finished with the suspension, wilbers fork springs and new fork oil, and an R6 shock. Time for a service. Air and oil filter, plugs and oil change not too difficult. Hmm what's this exup thingy. Not much happening when I switch on. Flap itself moves, cables are OK. Took an age to wiggle the servo out, connected it to a spare battery, and it moves - but quite slowly. Any thoughts - should it turn quickly, is it worth taking it apart to have a look, or buy a 2nd hand one?
