    Frontend feels light

    At least he didn't go for the easy joke: Frontend feels light? Viagra could help!

    Anyone buying an iPad 2?

    Bounce - My amps and pre amps are vacuum tube (surround processor is not valved). Adding network connections introduce electronic noise which I don't want. Having the IR receiver on them doesn't help but it isn't as bad as the internal network devices are for noise. Vacuum tubes... How 1930's...

    FJR Computer swap for Seq EFI?

    1) Yes - My initial question was answered: The general consensus is that no one who's answered is aware of an aftermarket ECU supporting sequential firing and the injectors which go with it specific to the FJR. 2) The second issue - Is my fuel economy normal for the model and year? Was answered...

    FJR Computer swap for Seq EFI?

    I'll try to be as direct as I can here: What device does one need for diagnostics involving the FJR ECU? Industry standard devices like the Snap On Solus are clearly out so I assume there is a Yamaha specific diagnostic plug-in which is required. Something like the Suzuki Diagnostics System...

    Thank you. Should I experience a heat problem I will try that.

    FJR Computer swap for Seq EFI?

    I have access to an EGA. If I find readings which are off I am still unsure how I would go about finding the source of the issue without checking each device independant of the others as the Solus does not seem to work with the FJR (so said SnapOn by phone). The heat issue seems to be GenI wide...

    Oh! I tried to give Zorlac a +1 but it says I used all my +1's on ionbeam (+2), phroenips and Denver_FJR (Action Failed: you have reach your quota of positive votes for the day). It's a new day!

    I understand messing with someone but hitting the red - button to get them knocked off the site is petty. Thank goodness for the anonymity websites provide I guess, huh? Seriously, feel free to send me a message to tell me I'm a d*ck but don't eliminate my ability to participate in the very...

    5JW-28199-20 is what came with the motorcycle. There is part of the problem. Wrong manual. Didn't know I had the wrong one. But again: There are also major differences between what everyone is saying they are getting in terms of fuel economy. Two people were getting the same levels as I am...

    joebiodiesel - I agree and I'd like to use the Solus to test it but do not see a CAN-BUS or OBDII harness to plug into. That is why I keep asking what the resistance readings should be (v = iR) so I might test it with my multimeter instead. I thought I'd check the O2 sensor first as it plays...

    Paraphrasing page 3-10 from the owners manual (I cannot legally make a direct quote and cannot provide a photcopy of the page - I will call Yamaha at (800)962-7926 later today for permission): To take the front seat off- Use "lock opening device" and follow visual instructions shown above and...

    Zorlac - We are back to the leg thing: The footpeg position is such that I don't dare travel over the speed limit on this bike. If I am focused on my legs I cannot focus on the road and could easily wind up with a case of Dead at high speed. The speed limit here is 65 and 65 I go. Wait a...

    ionbeam - I agree that an oxygen sensor plays an important role in emissions and it does so by monitoring fuel burning efficiency. If it reports a lean ratio the change in resistance or current will signal the ecu to increase fuel volume. If it reports a rich ratio it will signal a decrease in...

    I don't doubt that I can use 87 as the compression ratio is only 10.8:1. Dealers are often full of it which is why I tend to do the majority of work myself. I bought the bike from the previous owner with whom I went to the dealer to pick the bike up. I don't doubt I can use 87. The difference...

    charismaticmegafauna - I'm not ripping you, I just have a background in Computer Science and an in depth understanding of automotive/motorcycle repair. I do hope my response provided you with some insight. What I wrote to you is the reason you are sometimes told that you need a sensor when you...

    Warchild - Removed. Phroennips - The only 86 is on page 8,5 under the Torque section of the conversion factors ("86.794" and "0.8679"). Nothing under "Fuel" for octane. Nothing under "Octane" for Octane. Nothing under "91". I am excluding unrealted returns in this line of reply. David

    FJR Computer swap for Seq EFI?

    charismaticmegafauna - The ECU has a certain range in which the oxygen sensor is expected to function. High readings for lean, low for rich (or vice versa - Not sure what the range is for the FJR). If the fuel system is providing fuel at a normal rate and combustion is producing the standard...

    Just looked through the owners manual. The number 87 shows up on page 6-33 ("EAU03087") and 8-5 ("Volume, Capacity" "X 0.8799"). That is all. I do not see any section which lists the octane requirements for the fuel.

    FJR Computer swap for Seq EFI?

    Warchild and ionbeam (and others) are saying that my fuel numbers are off from the average. If that is so then the oxygen sensor is still a potential issue. If it is providing false readings to the computer which while false are still within spec, the fuel economy would be off and a code might...
