Help ok hold the ride

<< < (2/2)

Bryanj:
Neither should have direct flow from tank, fuel should go from tank via tap and filter screen to bowl then to outlets, which is why if the washers are duff you get fuel to the carbs all the time as it comes down the screws and bypasses the tap

Johnwebley:
just a quick thought,I recently had to drain my tank,(CB500-4) the fuel tap did a similar thing,full flow from one outlet,dribble from the other,this made me think,a very rare occorance !

 is the fuel taking the line of least resistance?

 in normal use,it fills each pair of carbs,guessing the full flow fills faster,when that is full it means the only out of the tank is by the "slow"
pipe ?

as both sets of carbs will normally use the same amount of fuel,it is likely to happen after maybe a dry start ,were the carbs are empty,
or if it runs onto reserve,

this is not a sure cure,but something to ponder on,

try putting your finger to stop the flow,and see if it increases in the other pipe,

RGP750:
Happy again. It would seem the problem was down to low fuel,i had about half a gallon in the tank.
I put a couple of cans in and all seems well.
Just done a 70 mile ride and pulled to 70 no problem ,lovely to ride. ;D
5 miles from home and it chucked it down with rain so now have a bit of cleaning to do, oh well the
ride was worth it. Roll on the next sunny day.
Cheers to Bitsa for his guidance over the last 6 months.

Bryanj:
