R1100RS heart stopping moment

Postby andys » Fri Jan 03, 2020 12:06 am

Started her up this morning and all was well.
Got about 100 yards down the road to a T junction, stopped and it stalled.
It was very reluctant to start up again and when it did ran very rough with clouds of white smoke billowing out of the exhaust.
Then after about ten seconds the smoke cleared and it felt like it was running properly but not 100%
I did about 50 miles and eventually felt like it was back to running fine after about 5 miles.
Any ideas
Its never done that before
I had filled up a couple of days before.

:sad:

On a normally aspirated engine (of course I suppose nowadays, FI is normal...) it could be as simple as a stuck float, a bit of crud in a jet way, temp block in tank cap, no worry,

On yours, it could simply be time of year. Maybe a bit of moisture on a contact, maybe on a sensor a bit damp.

Before you start thinking HES, maybe some more riding. Engine hadn’t warmed up so not HES? Could be crappy fuel...

Or the next time you get to a junction, pull the clutch in :wink:

Yes of course I pulled the clutch in before stopping.
That's when it died

Hi
my K sort of did that yesterday, stalled at the usual set of lights.

I close the choke as soon as I set off---

Runs and Idles ok with no choke, but wont "pick up" without choke. ECU/ "Choke"/ Engine temp/ Air temp sensors confusing each other
Then fouling a plug? Which a run clears.

On an Injected motorcycle to enrichen the mixture the ECU increases the time that the injector opens to squirt more fuel into the cylinder

to "burn" that fuel properly requires more air ....So your "Choke" lever is actually a throttle butterfly opener

It opens the butterfly just a little to allow enough air in to burn the now extremely rich mixture

My recommendation is to run the bike with "fast idle" whilst you pull on helmet and gloves and set off and flick it off "Unless" you have a lot of stops to get out of town? Just keep it on a little longer whilst you negotiate the stops and turns and flick it off once on the open road

NOTE The colder it is the more fuel is injected! So the fast idle lever really does require to be open or the very rich mixture may soak the plugs and be a pig to start again !

Hi
I live in a city so---have a lot of stops to get out of town.

Thanks for the explanation J, I "Sort of" knew some of that, but could not explain what went on

I'm ALWAYS Conscious of your Note and NEVER start the K unless it is going to get at least a 5 mile test ride. The bike Windmill John sold AndyMcG caught Andy out with the fouled plug trick.

I always put my helmet and gloves on before starting the engine cos the R will not idle when cold while I get kitted up

Yup, terrible with the earlier model ‘K’ until end of 86. Stall your ‘K’ just after starting........ take your car :grin:

It doesn’t hurt anything to leave the ‘fast idle’ lever pulled, even after the motor has warmed up, and it can effectively be a low speed cruise control. You cruise at 20 mph or so on it. :grin:

Explain that for me George ? Which R ? Airhead?? Oilhead ??

I must admit I have a cheat for the Airhead I have the underside throttle lock (cruise control) but a wooden clothes peg between the inner side of the twist grip and the switchgear held it open for me before I fitted the OEM lever kit :grin:

But the Oilhead should run at 1200 ish rpm while you get your gear on whilst on the fast idle lever If not it needs adjusted ?

I use the same process as George on airheads, and turn the choke off a few miles down the road, as far as I can remember I did the same even when airheads were " new / current " models.
There seems to be a gap between ticking over on choke and ticking over without.
