690 with Safari Tank...
« on: September 23, 2014, 01:52:45 pm »
I've had a safari tank for a while now with no problems, but on my last two outings I've
had an issue where the fuel pushes up and out of the Safari over flow in the filler cap, this happens after I open the safari fuel tap.

I do the normal closing of the safari fuel tap, fill both tanks then ride 100 odd Kilo's before opening the Safari
tank via the fuel tap. This has always worked but as mentioned the last two rides I get fuel on my lap. :(

I then open the filler cap on the rear tank and I can hear a suction or escape (sounds more like it's sucking in not sure though) of air.
The fuel in the safari tank then drops down but after some more riding it just does it all again.

Any ideas?

Thanks.

Sounds like a breather is blocked somewhere, and you're getting a vacuum -lock. Had this happen to a mate of mine, and it was found that the breather/vent valve on the cap was blocked with dust. :sip:

Thanks guys, will check that out.
777 - The RR cap - did you use a breather pipe on the cap or did you retain the stock breather pipe under the seat?

Just for closure on this topic - I cleaned out my rear breather pipe using an air compressor. Theres a tiny
little ball in the neck of the petrol cap on the rear that was jammed in and I think this caused
the problem. Since blowing it out and cleaning it I have not had the problem occur again.
