    Gas mileage on a 98 5th gen

    As said, it seems that every '98 owner in Italy gets bad mileage, regardless of the injectors conditions or the speed. Y2K catalyzed models are known for having a MUCH lower fuel consumption. The bike runs great anyway.

    Cam reinstall - timing help needed

    It IS a concern, though I don't know how much. And the corroding is a concern. Somewhere in the Honda manual it says to NOT use carb cleaner on the throttlebody as the bores are coated in a molybdenum something or other to prevent corrosion. I didn't mention it because you're well past that stage, but yeah. Make sure to do anti corrosion. Also very smart to do the o rings. Mine were a crusty mess. It's a 5th gen, and 20 years takes its toll on rubber, regardless. They're a cheap, easy change if you have the throttlebody off anyway.

    Replace bulbs on a 5th gen

    If you switch to LED signal lights, you'll need 1156 and 1157 LED's... You can also get a simple replacement relay to fix the fast flashing issue. Google the relay, superbrightleds.com sells them. It's a simple relay with only two wires and it works Great! https://www.superbrightleds.com/moreinfo/flashers-load-resistors/electronic-led-flasher-relays-for-motorcycle/787/842/ I just upgraded to LED lights all around on my 3rd Gen. I also bought yellow LED lights and Red LED lights for the tail lights. It looks Great!

    Video "History of the VFR"

    Overall, the video was a pretty good effort. He got most of it right! But if you're doing a history of Honda V4s, or even VFRs, you really have to differentiate better between Honda production bikes and HRC race bikes. The production bikes are easy: From the VFR750RH RC30 in 1987 to the VFR750FL RC36 in 1990, there were only five other 650-899cc Honda production models: NT650J-M (Hawk GT/Bros) RC31, VT800CJ (Shadow) RC32, NTV650J-L (Revere) RC33, PC800K-L/R-W (Pacific Coast 800) RC34 and VFR750PK-R/P2K-R (Police) RC35. HRC has manufactured all of Honda's works racing motorcycles since about 1982, but has also modified Honda's homologation models (e.g., VFR750R RC30) for various production-based racing series. The "VFR750K" is a case in point. This was not a production model, so calling this RC24-based HRC special the "VFR750RK" is a bit of a nonsense. There was already a VFR750RK RC30 in 1989. Maybe the HRC racer should have been called the VFR750FKR or something? Ciao, JZH
  8. SP's have one gremlin....... If the sun is shining from behind while parked up, the screen's inside will act like a parabolic mirror and melt the cockpit... Mine came with that mark and I camouflaged it with a wee sticker. But, jolo and all that....

    Replace bulbs on a 5th gen

    If you are OK with the signals flashing really fast, then disregard this. If you want the normal signal flashing speed you will either have to add ballast resistors in parallel with the signal LED OR acquire a solid state flasher relay that doesn't rely on the resistance of an incandescent light for switching frequency. Ballast resistors: https://www.amazon.com/4Pcs-Aaron-6ohm-Load-Resistors/dp/B00L4V9ECY/ref=pd_lpo_vtph_263_bs_t_1?_encoding=UTF8&psc=1&refRID=2WYD8NQ5HQQ0NAEFZD3A Flasher Relay: https://www.amazon.com/iJDMTOY-Electronic-LED-Hyper-Fix/dp/B00XAU66V4/ref=pd_lpo_vtph_263_tr_t_2?_encoding=UTF8&psc=1&refRID=Y4HD00YVM6XPBRZ8S3V8 Another possible issue by swapping from incandescent to LED is that your regulator-rectifier will have to dissipate more heat if it is of the shunt type (OEM, FH020AA) because this energy would normally be dissipated by the bulbs. If series (SH847) then this is not an issue. That said, this is a nearly trivial amount of energy, so it may not be an issue.

    Gas mileage on a 98 5th gen

    AFAIK, there is NO difference between the US 48 state ECU's & the rest of the world for the 98/99 models. There is a possible difference for the 00/01 models as in Europe we got HECS-3 emissions kit for Euro2 compliance (not sure =if that was included in US models) & HISS ignition chip system for theft prevention. Synchronising your starter valves correctly improves the smoothness of the engine everywhere, especially cleans up the free revving nature of the engine. Gas mileage is hard to improve on the VFR its its one bad point. But on a stock setup 00/01 model you should get 200 miles from a tank, hits reserve around 185, even when ridden in a spirited fashion. When cruised you should get 200 before reserve. My tuned up version hits reserve around 160ish miles, but has reached 180+ when cruised on a eurotour through the Alps.

    eliminating VTEC on 6th Gen

    I am sure I have read about this being tried before and the bike ran miserably. Wish I could remember where.

    Replace bulbs on a 5th gen

    I'm going to replace my original headlight bulbs with whiter Osram Night Breaker bulbs, and i have seen this beautiful mod: The mod is visible in this video Now i just want to know if those LED bulbs may cause problem in the long term. I want to stick to halogen in the headlight, exactly for this reason. I would like to use LED just for the turn indicators and for the parking light. Am i doing right?

    Gas mileage on a 98 5th gen

    Hi, sorry for not replying immediately to this interesting debate. Well, what can i say...When i did the flapper mod, i got an immediate advantage at very low rpms (under 3500 rpm, so to say). The V4 is not the smoothest engine at those rpms anyway, but now it's much better. Don't know why it behaves in this way, it should be the opposite (open flapper valve = roughest behavior at low rpm), but currently i will keep the flapper mod. Snorkel mod - just a matter of better noise 😉 Gas mileage? It's always the same - bad. You go slow, you go fast, it seems that the injection system was originally set to always squirt as much gas as possible in the cylinders, regardless of the conditions. I drove my bike for half tank at hilarious city speed (3000-4000 rpm) and the result was always the same , a miserable 235 km (146 miles) from a full tank, excluding reserve. Just yesterday i heard another 800 Fi owner - he had one non-catalyzed (1998) and one with catalyzer (2001). Well , he said exactly the same things - the '98 has a better punch at midrange but has crap mileage and runs always quite rich (the exhaust is always a bit blackened after some hundreds of km). Fuelly mainly shows results from US bikes, the few non-US bikes have worse result about gas mileage. Exactly for this reason, i would like to know if there is some differences between the 1998-1999 Italian-European ECU and the USA one.

    Just my luck. T-Rex no cut frame slider FAIL

    Ouch - keep us posted, this is actually my next planned mod... I know they will say, it would have been much worse without, but if no real advantage to having them, not sure if I will still buy. On another note - I actually saw a guy back into, knock down, and then drive partially up the side of a bike outside a burger joint. I pulled out my phone and recorded him lifting it back up and he got to the exit before I stepped in front and told him it was all on camera. He said he was just going to go to the back of the restaurant, but this guy was bailing had I not caught him. :)
  15. I'm in contact with the manufacturer. It might be just a one off production flaw. We'll see what they say
  16. I guess I'll cross those off the list of future purchases. Sorry it had to happen to you, though, mate. That sucks a fat one.

    eliminating VTEC on 6th Gen

    Seems it would suck a whole bunch extra fuel, but it would make that RPM transition way smoother.
  18. Hi JZH, Thank you for your donation of --. We look forward to improving the forums with your donation. Thanks VFRDiscussion
  19. Here you go: https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.co.uk%2Fulk%2Fitm%2F273649792185 He made this listing especially for me. If it’s no longer live just do a search for his other items using details in the title. Not yet, Gig. Thinking a simple home-made ally bracket will do and maybe I should stick bearings/bushings in the bolt holes? Not sure how I’m going to tackle that yet.

  21. Thanks highside, yep just using Mohawk's pic to visually check the posi of MTB o2 sensor. OP header will have two O2 sensor bosses at 2000-2009 OEM header's O2 sensor locations: one O2 sensor boss on secondary tube after left front/left rear primary merge, one O2 sensor boss on secondary tube after right front/right rear primary merge Cheers
  22. I'd get 3 bungs put in the pipe myself. Like this. A single one past the last collector and one each just past the other collectors. Then you can tune each set individually if you want. Just my thoughts on the matter.
  23. That looks as if the thread has been ripped out. Eek. Not good 😪

    Video "History of the VFR"

    4800 is mass produced! Sure they were hand *built* by HRC but they were made from production moulds etc not sandcast specials...like the RS750's or RVF750's In comparison Honda built EIGHT RS750's for '84. Not sure exactly how many but probably similar numbers for the the RVF750. Again, it is a prototype racer, just as special and as unique as a MotoGP bike is now. It looks (quite) a bit like the VFR750R (RC30) because that was a homage to it as well as a homolgation special for the "Superbike" championships to replace the VFR750RK (the racing version of the RC24). And finally this is a VFR750RK, entirely missed from that "history" which was the race kitted RC24 intended for competing in TT F1 and AMA superbikes. The RC24 won the AMA superbike championship twice as well as runner up in the F1 and senior TT....although those were the very super special 6X versions which made another 10ps and had even more trick HRC goodies.

    6th-gen Supercharger Kit

    Cool THANKS.. Wish Dan and his kits were still around.. Never know maybe one day he'll pop back up some where.. I only found one Dyno shop in Perth Western Australia that would touch the bike.. As soon as you say its got a SUPERCHARGER Kit they all go funny on me and back away.. 😞 Odd.. Yeah it could go BANG but I'm willing to take that chance.. Not there bike they are going to blow up.. HAHA.. 🙂
