broken down in Belgium help needed ?

[bowser]

off touring in Belgium with a couple of tossers of the site and its been a bit of nightmare sofar, need some help now I know the search engine is your friend but I cant find it and borrowing sombodys computer.

All the bikes are R1100GS, we have one runnijng very rich, now its not somthing I have had to play with, is there an easy way to lean up the mixture?

Second problem is one of the bikes is an early one with the throttle cable that goes to lefthand side and then the cable from the left over to the right hand throttle body, the end of this one is about to break, now I can get a new one made up no problem, but never had to change one before are there any particular pitfalls to look out for, I know the obvious make sure the cables seat correctly, I am thinking more of syncing the two opening together etc.


any advice would be greatfully received.

I cured my rich running by setting the TPS voltage, just connect a digital multimeter to the end wires in the TPS connector and set the volts closed throttle to 0.36 or thereabouts, throttle synch by ear or it is possible to make a manometer from a scrap of timber and some aquarium plastic tube very cheaply.
good luck

if it hasnt got a cat its got a pot at the rear, to adjust the mixture

 

[Canuck]

look up under rear fender on right side... I believe that the adjuster is there... should be black and require a screwdriver. I'll have a look for the a photo. Worth noting that some bikes don't have them.

Turning clockwise weakens the mixture, anti-clockwise richens it. I have also read 'Do NOT fiddle with this pot unless you have a CO monitor on the bike. You could destroy your engine by running it too lean.' I think tiny adjustments is the key but only as a last resort without a co2 monitor.

Edit... here it is...

get the cable on and jus set it best you can, to get you home or to a garage

I'd check the TPS voltage as advised before messing with the CO pot.

For the cable, do the best you can by feel - make sure the butterflies are resting on the stops and not being stopped from seating by the cables, then get someone with a finger tip on each butterfly as you open the throttle - try to get them opening at the same time (I got mine near enough like this before I was able to use a manometer).

Hopefully Steptoe will see this and offer some advice.

thought that was the case, I set mine the same way and it runs fine and never bothered trying to be more accurate, just really wanted reassurance that I was thinking the right way.

think we will just leave the running rich for now, it works and we will wait till we can do it properly but thanks for the advice

Stop faffing about and go to the pub.

If it has suddenly started to run rich it could be the tps has gone tits up. Swop it with one from the other bikes to check.

Those one piece throttle cables are a fecking nightmare. Good luck.

That should put his mind at ease

Hi Bowser

I just thought I`d let you know that I`ve recently returned from a 2,700km European trip on my Ural and it gave me no trouble or problems at all.

Sounds good in Km but it's only 1620 miles, a weekend jaunt on GS

In the end the bm dealer in Aachen had one in stock, and it was so simple to fit it was untrue.
Balnced the opening of the butterflys by touch and guesswork and the bike has run flawlessly since.

What is normally the problem when fitting them? It was so much easier then changing mine I had even considered a conversion

But your mate's bike didn't even make it out of Essex without a complete failure
