After i got back from the weekender, i took the monnie to the Dyno place, as arranged.
A day or so before i got it back, the guy phoned me to ask if the bike had ever cut out on me, as if it was running out of fuel.
I told him it hadn't and he went on to say that it had cut out twice on him, once whilst warming it up for a Dyno run, then again when he took it out for a road test after setting it up.
On both occasions it started up again, albeit spluttering for fifteen or so seconds, before it started to run normally.
He cleaned out everything fuel related, except the pump, the carbs were cleaned and re-jetted.
On Sunday, when i was heading back home from a ride out with a couple of mates, it started to act like it was running out of fuel, it finally conked out a hundred yards or so later.
I checked the tank and it was half full, so i tried to start her again and it did start, although it seemed to be two-stroking below a quarter throttle.
I gave it some welly to set off and it ran ok, provided i kept it on the boil, i had to throttle off to turn on to the A55 carriageway, it farted about until i wound it on, it ran ok on the carriageway and most of the way home, except if i had to slow down for roundabouts or junctions, then it would splutter a bit.
By the time i got home, it was running pretty normal and ticking over when i parked up.
I phoned the Dyno man and told him what had happened, he feels it could well be the fuel pump acting up.
There are no kinked or split pipes, including the vacuum pipes to the pump.
Any ideas guys?
