The plot remains thick. Pulled the FPR last night and isolated the test to it. It opens at...36 psi :eek: I blasted some solvent through it, and hooked a pick into the spring from the back side and pulled it around. I could move the diaphragm around a bit but i cant confirm that i...

Excellent, i'll fall back to that after i do some experimentation on this one. I'm going to try soaking, over-pressuring, ultrasonic, and whatever the term for throw it against concrete a couple of times is. if it comes down to it, uncrimping it and opening it up. What have i got to lose? My...

Good idea and thanks for the info about the R6 pumps and peoples experiences. I tested my fuel pressure gauge with a tire inflated to 35 psi. The tire was checked with a Snap-on tire gauge. I'll see if i can source another fuel pressure gauge and run the test again. Still hoping to find...

F/I i'm on board with your synopsis. Combine physics, thermodynamics, and a batch-fired fuel injection system and i would have a hard time explaining why fuel WOULDNT be present in the intake after shut-down. Hopefully some others verify this in time. Quick question, could you describe a...

Thanks for the tips and suggestions F/I and Townsends! F/I: I'll check continuity on the switches and coils, and rebuild the boots. The plugs are NGK CR9EIX's and were replaced after the miss was noticed on the original CR9E's. Gapped to Yamaha spec and installed appropriately. On the...

The R throttle bodies held easily for 5 minutes. I cycled them with 9 volts, it was easier to solder up a 9v tester than to pull a 12v battery. I used isopropyl alcohol and then water for the spray test. I'll upload a video of the spray test tonight, pattern was reasonable. This all...

Here's the unit, after pulling out of storage and conversion to n-spec This is down one of the v-stacks, approx 1 hour after a 30-min ride. I don't know if you can see the fuel, playing with the brightness on your monitor may help. Its a bluish-green. Its identical across all 3 closed...

Affirmative; the fog is after shut down. I do not recall the service manual giving a leakdown rate for the FI system either. Just a go/no-go on fuel pressure. I ran you test last night and did some more diagnostic detective work. I'll follow up in detail with photos but in summary, the FZ6R...

Thanks for the data; its very helpful! If i had enough posts to edit my signature it would be: 2007 FZ6 - 9,500mi - Stock - Naked conversion - Renthal Bars - Fender Eliminator At some point the bike had a scorpio alarm and lojack on it. I think the lojack is still there but i remember...

Thank you for the suggestion. I'll clean, dry, and then pressurize the spare TB over paper to look for evidence of leakage. I'll be able to better tell if the cam timing is off when i hook up the vacuum gauges, but in my experience even 1* off will make itself very obvious, and this bike...

Great question! Theres a couple of ways/stages: The easiest is to remove the airbox cover, hold the throttle open (with the bike off :D), and shine a light down the velocity stack. If the rotating assembly stops with one of the cylinders in the middle of the intake stroke, you'll even catch a...
