    No vehicles right now. Soon to be a 2004 VFR800.
  1. Its not that the bike needs more power, it is that I need to tinker.
  2. Does the vfr800 use a mass airflow sensor MAF or a manifold absolute pressure sensor MAP to determine how much air it is breathing? If there s a MAF somewhere I do not see it in the diagrams. Too bad. That means that for airflow improvements there needs to be some remapping. MAP sensors almost work as well but may need some remapping for something like a cold air input. MAP + IAT the ecu could theoretically calculate the mass as flow. Now I see dry NOS systems which simply depend on the o2 sensors but I would not want to risk doing NOS without a PC. Do power commanders all have switchable maps that could be triggered at the same time as the NOS?
  3. hey I'm old and I jabber a lot.
  4. Never had an auxiliary tank on a bike but I did have 2 50 gallon auxiliaries on my pickup for total load of 120 gallons. Since I got 6 mpg I could go 720 miles.LOL. Anyone try to extend their range with the last Vetter fairing? I like riding but anything over about 3 hours seems excessive to me. I'm not knocking your pleasure but its not mine.

  6. Its summer time in Texas and I know this about riding. The faster you go the cooler you feel until the temperature hits 95 degrees and then its like riding into a blowtourch. There are vests which circulate cool water in tubing to jeep you cool. There are the primitive ones where to cold water must be prechilled and it seems these would be useful on short trips. Then there are the complex ones which use a peltier chip to perform active cooling of the water. Prices can range from under a hundred for the simple ones to 700+ for the complex Peltier chip based ones. I found some plans online for a complex one I am going to make. My question is how well do they work? Anyone have one? Would it make you comfortable enough to go riding in 100 degree F weather?

  8. This is beautiful. About the only advantage I can see to the exhaust under the tail vfr is if you wanted to stealth a turbo.. The riser pipe would feed the turbo and the turbo would exhaust under the seat. You could probably even keep the cats but to maintain the temperature up to the turbo you would probably want the exhaust ceramic coated. This is not a busa beater but just small quick spooling turbo.
  9. Its steel. You could probably bend it 90 degrees and not have it break. Therefore it must be metal fatigue. Any resonant vibrations that you know of? Interference between the exhaust and subframe sending engine vibration into the subframe. Did the metal seem unusually hard? I would expect a low carbon steel here which should bend before cracking. If they used a carbon steel perhaps it was not properly tempered after hardening. Unless it was mishandled at the factory and not tempered after hardening or unless Honda has forgotten destructive resonance and designed another Pugent narrows bridge this does not seem like a feasible occurrence for the materials which should have been there. If the broken part is still available can you determine its Rockwell hardness? I'm not an expert on Honda steel but my guess is if the Rockwell is higher than mid 50s it was not properly tempered after heat treatment. That makes it a manufacturing defect.
  10. Blow a light stream of propane into each carb as the bike is idling. If one of them gives more response that the others I would expect that that one would need recleaning. I'm assuming that these are CV slides. I suspect that properly working carbs word have relatively stable slides. Spray around the base of the seated carbs while the engine is running to be sure you.don't nhave vacuum leaks. Attach a set of vacuum gauges and attempt to vacuum synchronize. Try recleaning everything with carb cleaner (toluene). Don't burn yourself but see which exhaust pipes are not hot. Spray carb cleaner down the throats of carbs on non running cylinders. Is the mechanical linkage such that you swap carbs. If you swap and the running cylinder goes with the carb then the other carb has a problem. If the running cylinder runs with the other carb then you have a cylinder problem. Have then heads come off? Are you sure there is no debris keeping a valve.open or shut when it should not be? It does not sound like you will have an easy answer but perhaps cleaning with a carb cleaner like Berrymans (which is mostly toluene ), might help. I'd way to try to clean organics from the carbs with Lye (Sodium hydroxide) but this can dissolve.aluminum as well. Notice that I'm using a shotgun approach and trying everything I can think of. Perhaps some of this will be useful. Perhaps it will not be useful. If you diagnose the problem let us know what it was and how you fixed it.
  11. Awesome job. There is nothing quite so rewarding as venturing into new craft and pulling it off. And you did. I imagine you look at the result and say I could have done this and that better but I did OK. Nonsense, you did much better than OK. Even if you become a world rejoined bike bulder you will always look on this one and wonder "How the hell did I manage to pull that off". It is a singular moment you will always have. NACA was the American aeronautics agency that preceded NASA. And a NACA vent was designed to take surface air to the interior without causing turbulence or disrupting the laminar flow along the rest of the outside skin. Its not going to bring as much air in as a scoop would but its not going to disturb the rest of the airflow like a scoop would either.
  12. And as for going 140? I got the Sabre up to 120 and it was still pulling hard. I realized that the Sabre would go 130 mph. I also realized that I would not. I imagine the experience will be similar on other Honda v4s. I realed in a line of cars. Then I wondered "where is that demented laughter coming from? Oh, that's me!" .
  13. I haven't got my bike yet but it comes down to gens 6,7,8. In almost 10 years on a v45 Sabre I had one crash. Hard on the brakes to stop from 50 mph at a light which turned yellow I hit an oil patch in the road and lost the front end. Cracked both sides of a Nava Kevlar helmet. Wore the metal studs off the palms of my riding gloves. Abraded all the way through one elbow of a leather jacket and got my only injury a shallow scrape the size of a half dollar on my elbow. I learned two things. 1. Safety equipment works so use it. 2. My next bike will have ABS. My bike had a minor dent in the gas tank and no other damage. I shifted to cars for a while, my next vehicle was a third generation RX-7. Sort of a motorcycle with 4 wheels. But I'm going back to bikes. I like that the 1200 is shaft drive. I liked it on the Sabre as well. I don't like that it is nearly 600 lbs but am encouraged that people here say that it handles lighter than that. Going back to my early years I rode a small Honda (160 i think) and knew nothing about maintenance and thus broke an unlubed chain at 30mph in the driving rain. The chain wrapped around and locked the rear wheel. I did manage to keep the rubber side down but it was interesting. Looking back I now realize that chains need care and lubrication and that hooked sprockets are not a "wonder why they did that" interesting feature, but still I prefer the shaft drive. On the other hand the Sabre was a perfect fit for me (at 525 lbs and 85 HP ) That means the 800 is like a Sabre with 20 extra HP, a fairing and chain drive. I guess I need to test ride both.
  14. I had a mazda miata which would overheat on hot days especially in slow driving. I changed the water pump, added a bigger radiator, modified the coolant flow, added more powerful aftermarket fans. After every mod the problem got a little better but did not go away. Then I dropped in an aftermarket alternator and the problem disappeared. When the stock alternator got hot it cut voltage. With the voltage reduced the fans did not turn as well which overheated the engine and consequentially heated the alternator even more. If your VFR is overheating one thing to check is whether you have a voltage drop associated with the heating. Most auto parts stores will carry a thermostatic relay that has a probe which sticks between radiator fins. Some of these are cheap, primitive electro mechanical switches which rely on bimetallic switches and most of them have a dial to set the triggering temperature. You can wire one of these to any circuit with enough power to run the fans or connect them directly to the battery through a fuse. If you directly connect to the battery the fans will continue to run after the bike is turned off until the radiator reaches the cutoff temperature. There are a large number of aftermarket radiator fans on the market and many of them flow much more air than stock fans. They are frequently slimmer as well because they are pancake fans where the fan blade body is part of the motor rather than having the motor and the blade as two separate components.
