Suffering from Shock

[Disaster Area]

Hi,
My 1100 has been running very rich for a while and I finally got round to taking it to the dealer to let them suss out what is the matter. I wasn't expecting the phone call that I have just received. Could somebody help me with the following questions:

Would adjusting the tappets and replacing the fuel filter help with her running rich? Is re-setting the motronic by pulling fuse 5 worth a go?

The main thing that I wasn't expecting was that apparently my front brake master cylinder has leaked and has done so all over the front brake light switch. The dealer has given me a quote for replacing the master cylinder and the switch, but on the email says that the switch is done in conjunction with having the tank off while they do the fuel filter.

I'm confused as the Haynes doesn't mention taking the tank off to do the switch!

Is the master cylinder leak a common thing and if it is, how easy is it to fix?

Thanks for taking the time to read and hopefully answer,

DA

The fuel tank has to come off for the fuel filter replacement and maybe the removal gives them easier access to the switch which is why they are saying they will do it in conjunction.

I would have thought a dirty air filter would contribute to the bike running rich rather than a dirty fuel filter

Have you asked how and where the master cylinder is leaking? There is a rubber diaphragm that helps seal it - I once had a problem on an 1150 and it just required the diaphragm to be reseated.

 

[how far to]

master cylinder is easy and cheap to repair,about£30 for the kit,also read Steptoes sticky "Have you an 1100gs"at the top of this section Cheers

Where do you think the other end of the switch plugs into.

Ah, yes. Having now looked at a picture of the switch, I've just figured that out. I thought it was just a switch, not a switch with the cable attached!

Thanks for the replies so far, I'm mentally planning which weekends are going to be spent cursing in the garage.

try taking the switch off and flooding it with something like brake cleaner / acetone.

if the brake fluid is in there it would stop it working - but not cause real damage.

if you can clean the residue - it may be perfectly ok.

having an air compresser with a blow gun to dry it out helps


thats what i did when i did my front m/c seal kit


on the minus side - the fluid got onto the tank and removed paint
