will embark on my first valve adjustment on 02 520. found a good review off prceedure on holeshot, but, still have questions. excuse any for sounding "dumb." 1. finding tdc. on my xr this was simple as there was a window where one could turn the crank with a bolt and look for lines in flwheel. i do not see a window on the ktm, do you remove the side cover? whats the deal here? 2. the bolt that is tightened at tdc. how does this work. you loosen it prior to looking for tdc, find tdc, then tighten it back up? then when the valves are adjusted loosen it again, go past tdc then retighten? 3. what are you gus running as far as intake and exhaust clearances? thanks!
