  1. What can you tell me about my VF500?

    You have the VD56B carbs.
  2. Exhaust collector (balance) box

    "The angle of the muffler attachment outlets could be an issue though." From the schematics I have seen, I think this will be the problem. All the good collectors seem to be in the US. Over here the flanges where the mufflers/silencers attach always seem thin/holed from corrosion. I will be patient and keep looking for a decent F type.
  3. What can you tell me about my VF500?

    Put the air filter back on and run a 98 main jet in the front pair and a 95 main jet in the rear pair.
  4. What can you tell me about my VF500?

    From that video you are short shifting. Don't be afraid of revving the engine. It's what it is designed for. Some claim you shouldn't go above 9K rpm to save the valves but I don't subscribe to that theory.
  5. Exhaust collector (balance) box

    Answering my own question. VF500F/F2 1984 Collector 18310MF2671 € 525.83 incl. VAT Superseded by 18310MM1671 € 525.83 incl. VAT Same part number is listed for both 84/86 bikes 1984/85 VF500C 18310MJ8003 € 608.85 incl. VAT The Magna collector looks very different on the schematic so I think the answer is probably no.
  6. Exhaust collector (balance) box

    I think an 84 collector fits on an 86 so although the oil pan is deeper on the 86 there is still enough clearance. I will have a look at the part numbers on CMSNL.
  7. Exhaust collector (balance) box

    Anyone know if the collector box off a VF500C (V30, Magna) will bolt onto a VF500F/F2 (interceptor)? They look the same and as the bottom ends of the engines are the same so I assume it would fit but nothing beats personal experience. There are quite a few decent condition Magna boxes on Ebay but less F boxes.
  8. What can you tell me about my VF500?

    Does it need the choke when cold? If it was massively rich it would start without the choke. It would have to be hugely rich to limit to 110km/h. It would stink of petrol and be blowing black smoke.
  9. Yeah not much in the way of decent rubber in the OE VF sizes. I really doubt PIrelli will make more than one type of tyre in those sizes. If it were me I would still go on the VF. Less chance of crashing it. Remember the saying, "Trackday Sunday, Ebay Monday". Been there, got the tee shirt.
  10. What can you tell me about my VF500?

    To only do 110km/h means something is massively out of whack. You are messing with things that might have small impact on performance. You have a gaping chasm in performance. Is it actually running on all 4 cylinders? Is a brake binding? You have lost over half the horsepower of the engine so something very drastic is amiss. You need to go right back to basics and check all the fundamental things, like plugs, firing all on four, blocked air filter, fuel to all four carbs.
  11. What can you tell me about my VF500?

    If you are topping out at 110 km/h (units are mandatory in my world) then you have a very sick motorcycle and it really shouldn't be too hard to find the culprit. If on the other hand you mean 110 mph you have nothing to worry about. 700cc in how much time?
  12. What can you tell me about my VF500?

    Yeah well, don't be too worried if you don't get 196km/h. Most of us don't see speeds like that unfortunately. A more realistic target would be 170-180km/h in top gear with standard wheels tyres and sprockets. And well done for getting those rear headers off. You aren't a gynocologist by any chance?
  13. What can you tell me about my VF500?

    Yes, engines always run better in cold dense air. I noticed this on my VF500 the other day as well.
  14. The outboard motor would would make it an "interesting" vehicle alright.
  15. Too much information..
