Bowden box

[Slipperyeel]

Today I got a couple of hundred miles done visiting a customer. Perfect day. Spring has arrived!

My poor bike has been through bit of an upheaval, but it's riding beautifully.

However, on arriving near the South coast, going along some lanes with shit roads (ie very bumpy), I ran into an idle problem. It didn't take me long to narrow it down to the throttle cables.

The tank has been off multiple times so I'm guessing something isn't quite as it should need in the Bowden box. But I've never been in there to guess what might up.

Does anyone have any thoughts on this? I solved the issue (as in, it didn't reoccur) by blipping the throttle with the engine off and winding it to max throttle, then letting go...

Are you saying the cables are sticking, or stopping the throttle from closing as quickly as they should?

I think on this occasion, something with the cables was sticking, probably not equally, hence the idle not being good/lumpy.
To be honest I wondered if the postal in the Bowden box need some lube, like a shit of silicone spray!

a dead CAT sensor will make it run like a pig

motoscan just added engine adaption reset feature - I gave it a go - but without giving an error code, turns out one of my new CAT sensors has died and it sent one pot in massive enrichment cycle - adding on separate occasions 14.5 % over fuelling on opposite cylinder - tried an old sensors (which was intermittent in operation - again with out an error code) - it worked perfectly for 10 miles then gave up - and again same opposite cylinder to the one that's got a dead sensor went to 10% enrichment - it runs, but its nasty

when you disconnect BOTH CAT sensors the magic sick enrichment cycle never happens - but the bike will remain upset as that enrichment offset is still in the bikes adaptions - note always shows 02 sensor errors when they are both off , so there must be certain fault conditions that don't throw 02 codes

AS usual BUTTASS replies with Non relevant Bullshit !

The cable jumped out of its holder

twisting and pinging it settled it back in

Easy fix and no need to go down a non required rabbit hole!!

You will probably find the the cables have started fraying. In the casing, this happened to me on my 1150just became difficult to shut down when coming to a stop. This quickly became an rac recovery job so don’t delay, on the 1150 apparently they are supposed to be change at something like 56000 miles,
home servicing did not think of such a thing mine had done 90000 plus when it happend

My 1200 Hex had trouble when one cable came off the plastic cam wheel inside the cable splitter/divider box.

Easy to pop the lid off the splitter box and reseat the cable.
