Picture Wanted of 916 Cold Start Throttle Button

[northworthy]

Please would some kind Ducatisti post tonight a picture of the 916 throttle grip unit showing the cold start button - with a brief comment on how effective is it. Any usage or failure issues??

Many Thanks

Here it is ringed in red.

I've not had my 996 for very long but personally feel it is brilliant because it only speeds up the tickover by about 500 revs, so ideal as the engine suffers from lack of oil at 1st start up. Also as soon as you twist the grip, it clicks off, so no running with a rich mixture as can happen with a choke. 10 out of 10 Ducati. So far.

Brilliant Pete -and so quick in responding - many thanks.

Q: What is the tick over revs when you first fire the bike up cold then??

No problem.

On start up around 1500 rpm.

Pete - isn't that a bit high on starting a cold engine and what with little oil hanging in that rear cyclinder (rocker damage??).

Q: Is there any manual adjustment offered on that "button"? Can it be set at a lower lower tickover by adjusting that button? Say - 1,000 to 1,200revsas per my ST4s.

[petevtwin650]

Well my Suzukis tickover was 1400 revs when warm, so I thought 1500 was ok. I think you can just slacken the throttle cable off a tad and that should result in a lower cold start idle.

Be interesting to see what other peeps bikes fast idle at.

Like me, I think Pete gets out on his bike regularly enough for him not to worry too much about oil draining!

Jimmy - my problem is that I cannot (and not for not wanting to) so cold start lever on the ST4s is great because you can find a position where when starting from cold and a long period of non-use I can get it to start comfortably with no hesitations at approx 1,000 to 1,200revs and stay there for that vital first 90secs until there's oil up there around those rockers in the rear cylinder.

Hence my question - does that 916/996 button have any means of adjusting?

[stevel]

Will have a look, but suspect it must do, because mine revs at around 2 - 3K on the button, but interestingly I never need to use it in any weather. On a warm engine they are a bit reluctant to start on anything other than a shut throttle anyway

Cheers Steve - appreciated.
Living out here in the alps bikes get put away (depending on when the first snow falls- and the nice high mountain passes close -usually mid October) they get laid up until circa begining April. So I cann't ride out for a few months. A nice low tick over is then is what is required.

not that i can see mate, it physically moves the throttle grip

Thanks for that observation Jimmy - appreciated.

That tickover would be far too fast for my piece of mind Steve.

That's why I think slackenihg off the actual throttle cable would work. The warm idle shouldn't be affected as that's down to the throttle stop setting I imagine. Might mean you wouldn't get absolute full open throttle is all.

hmmm maybe, but I am not prepared to mess with what I do not understand!, I paint cars

Not found anything categoric, just odd comments that indicate that the lever simply cracks the twistgrip open a touch, no mention of adjustment though. If I was bold enough I'd open it up to find out, maybe in winter when I have time to kill!
