Andy your bang on....the mark should be up the top like the other fork leg...it makes no difference to measurement...just needs to be tuned 180 in the yoke to match the other fork top.

Ah, and is it exclusive to the 748/749 models or does it extends to the 998/999????
Sorry for asking so many questions guys, but i'm seriously thinking about getting a Duc."

My 998S was always cutting out in traffic.Great out on the open road,but come into a town and it would cut out.I just got used to blipping the throttle now and again to clear the tubes.
The 999 has cut out a few times,usually when the engine is very hot and you are pootling.Here's an example,crawling through the gates at Donington after the GP.Or after a hard ride you come into town and the lights take forever to change.Nothing I cant live with.
The bike has never cut out while on the move.

My 748R did it a few times when I first had it, set it up with a JHP chip 4.5 to5% co and raised the idle to 1400rpm and its sorted. Just got that bogging left when its been on idle at lights for a while. Powercommander next.

Weve found a lot of Dukes die rolling up to lights and an increase in idle speed sorts it. Almost as if the standard factory idle isnt quite enough with some Dukes.

Chippy had terrible problems with his 749 always failing to idle and cutting out, even after it had been serviced, it was actually worse after having the throttle butterflies synchronised.
The problem was greatly reduced by simply increasing the idle

I find it quite amusing to see all this whingeing about cutting out. If you can't cope with a high performance bike's foibles (as in something that is almost a race bike) then you should go get yourselves a nice little commuter. Anything in the state of tune that a 749R or 748R is in will be less than perfectly mannered at low engine speeds... they designed to be ragged..not plodded around on!

This might be complete ******** - but my Carb model 900ss suffered exactly the same symptoms due to carb icing. Is it possible, that a fuel injected Duke can also suffer icing (don't forget that it is the moist air that freezes, not the fuel).

Silkolene Pro FST (Fuel System Treatment) - a kind of anti-freeze worked for me. May be worth a try - about £7 quid a bottle.

its not a ? about copeing with a race bike twpd,the 749r is sold by ducati with indicators,number plate etc for road use,its a road bike,the bike should tick over on its side stand & when coming to a holt.

I can't say what the 748R was like, but what happens on the 749R is not the result of a highly tuned engine, it is a fault. On a bad day it will stall almost every time that you downshift.
