Hello one and all
I need your expertise desperately!!
MY wife’s bike (Bros 400) has a hissing tank. Every time you open the petrol cap, it sucks in air which would suggest there is a blockage somewhere.
I have checked the breather that runs from the top of the fuel tank and where is exits underneath the tank. All is clear.
I have checked the breather in the petrol cap itself by blowing an compressed air through it, and again, all is clear.
It is being a pain, because dspite the fuel being fed to the carbs via a fuel pump, after a while on the road, it will die if she stops and lets it run on tickover. Then it takes ages to fire up again. Fuel cap and pump are identical in looks to a 97 CBR6
I can’t find anything on the Honda Service Manual, Haynes manual or the Bros/Hawk forum. Have asked them the question, but for some reason no reply. Which is very unusual as they have been known to reply within minutes. (Different time zone as they are very popular in America).
Does anyone have any ideas as to the cause. The cap is idientical to my old CBR6, and my current VFR. I used to have a 650 Bros and when I swapped the cap over, the problem diappeared instantly so it is definitely the fuel cap.
I would preffer to fix itrather than buy a pattern cap, as this then means you need 2 keys to run the bugger.
Can they be stripped down and repaired, and if so, how?
Bit of a cheek asking you guys but I am well and truly stuffed! And the wife is giving me grief too!
