l`m here at 7000 feet, the highest capital city in the country. Denver is almost 2000 feet lower. So we tune for altitude and run boost as much as possible. Octane requirements go down which is nice but power goes down also due to the thin air. New vehicles require no adjustments at all but older ones need the timing bumped up,sometimes set at 28` max advance on a NA motor. They`re all different of course. l reset the timing on a Kawi triple a few years back and the guy wheelied into a tree leaving the shop,it was that dramatic a power difference. Anyhow does anyone know about timing the carbed Ducati`s? l suspect the fuelies have things sorted and l`m sure they`re set from the factory but what`s the procedure to revealing the ignition system to proceded with this? ln the past l`ve had to machine parts on some engines to allow adjustment and others you can just buy an advancer...ls an advancer available? any help appreciated and l`ll post my findings
