just had my first service done this week, - a 3hour plus job now they tell me, - belt tension, valve clearance check, - but i asked them to take out the restrictors as they had the tank off, "no problem" they say. Phoned them up to say i would be there in 30 mins to collect, asking if they got the restrictors out ok - "we did not know what you meant, never heard of that, we telephoned the top techie guy at Ducati UK, and he had never heard of the MS having irbox/tube restrictors". WTF???? Is it not standard procedure on fitting termis I asked. I took them in a message board print out of "how to do it". Looks like I have to spend a little time in the garage myself now. Ho hum.
