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 fuel, bike is starting. Thanks for the input!

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 one day while running idle... she coughed and stopped, and she still will not start. 1. Battery is new and fully charged 2. I hear fuel pump prime, so the flow chart I saw from Grum on relays should be ok to Fuel Pump 3. Checked for spark.. and saw spark plus got shocked, so seems electric works 🙂 4. Did check all fuses and cleaned them with contact cleaner. 5. Also noticed fuel on the plugs, not a lot but take fuel is flowing.. I am just not sure how to verify fuel flow other than drain tank (again), wrestle the fuel pump out and test externally? Side note.. 6. Working outside on the VFR but under cover - did have lot of rain and its humid tis time of year in South Florida.. suspected maybe an electric issue from moist, so jumped the service switch to check PGM-FI... this turned out to be learning experience. Found some old error codes, which i started troubleshooting (8 blink saying TP sensor, which I checked using ohm meter (OK) - pause then long blink being code 10 and BARO sensor). During the process I found out how to reset error codes in the ECM, so tried this and errors did not re-appear .. sooo putting air filter and all goodies back. Still no start. 7. As for the flapper mod, I did forget at first to plug the vacuum tube and bike has been outside, so I am sure there is some dirt on the bike, but if anything made it in there in the very short time, don't think it can prevent VFR from starting, right? Also, have a power commander, but now disconnected and wiring back to original. Where do I go from here?.. want to learn and too stubborn to throw in the towel... yet. Unexciting film on no start here .

Hi JPmoller, Thank you for your donation of 5.00 USD. We look forward to improving the forums with your donation. Thanks VFRDiscussion

Thanks Cogswell, for joining in. Well, doing it myself is the main reason I started working on the bike myself. Aside from some 'sadistic' fun - then, as you say, you only have yourself to thank for the mistakes. Reason I started was the local big bikeshop screwing up the linked brake system... while over charging for service. We live we learn, so why pay someone else to mess you up 🙂

Thanks Capt Bob - Grum found the 'bug' - tire was installed backwards and the wheel center on left side extrudes further than right side... did not notice at first.

Waouv - you are absolutely right! I see the height difference now in the manual... and yes, I need to go back to my tire man... in reverse. Thank you Grum - 1000 points your way once I find out how to 🙂

If sitting on the bike and right side front spacer is the bigger one, then I should be ok. Also, tried to swap to make sure i did not miss something, but then for sure right rotor touches fork.

Thanks Grum - sure appreciate the prompt reply. I called him and he said 'no - we run a clean shop'. He had a small part but he said it was mm thick like a washer. Hoping to get a photo from a GEN5 VFR left side front spacer installed - to actually see how far our spacer is sticking. Spacer plus the extra thickness on the axel left side is what gives the distance to the fork... so far not enough.

Guys, This is driving me a but crazy - finally had time to give my VFR 800 from 2000 some love. New tires - so took the wheels off and brought to shop. New tires returned and now I mount. However, It looks like the little spacer/ collar on the left side has shrunk?! Siting on the bike, nose forward - then right side has the thicker spacer, which is ok. Left side has the small spacer - about 10mm - and space goes almost flush with the dust seal. The wheel axel has a thickness, making some distance between fork arm and the break rotors.. but not enough. The bolt heads in the rotor touches the fork arm?! Wheel does not look centered.. what mess did I create? Remember thinking to take before-photos, but 'nah, looks easy enough' - two days later I was I had before photos, so hope you can help? Here some photos.. maybe someone can shoot me photo of how much left side spacer on front wheel on a Gen5 sticks out? I definitely do not have as much visible as service manual shows of 'left collar'. Called the shop suspecting he might have accidentally swapped my spacer with one he had from another wheel, but he says no. Help appreciated so I can get cruising again and regain some sanity.
