Yes - maybe I stumbled on new green technology. If I could make a VFR run on cow milk... and avoid a long methane cow fart out of the exhaust - then possible this patent could give me a happy retirement 😆

Just to finish this 'mystery' then as I said.. i changed the gas cap since original cap had frozen up and deteriorated. Got a key-less cap via eBay - so all good, however looks like its not watertight. Likely I pinched the drain hose or there was some crud in drain tube leading out from overflow by gas cap - nevertheless - fuel was badly contaminated with water, which became obvious when I ran the flow test - looked like a milk faucet. Here my small hook up and test result... good thing, fuel pump works as per design. Got my 5 oz in 10 sec :) With a good flush and fresh

I shall check that too. Service Manual has a special gauge for fuel pressure and requires engine to run, so will start by checking flow like below.

Thanks guys - I will check sidestand tomorrow, but not too hopeful. Bike was idle on centerstand when she coughed for 10 sec and stopped running. Suspect fuel flow trouble, but checking all options.

Guys - have feeling its simple, but making it complicated. I had water in my fuel.. tank drain line clogged - I drained and clean the tank, replaced fuel filter and hoses. Bike was up and running - all good.. maybe a little uneasy on low rpm. I read about the flapper mod in this forum, so decided to give it a go and also removed the snorkel. Seem to remove the un-easiness in low rpm, so happy with this. Next step was flushing hydraulics.. which is a task for a first timer on VFR, but its done. I had started the VFR a few times during service to make sure fuel was circulating, but o
