  1. What can you tell me about my VF500?

    I did read somewhere about one carb being jetted differently from the other three, I think on one of the VFR's to correct scavenging issues with the exhaust. Our VF'S run downdraft carbs on the front and sidedraft carbs to the rear....the characteristics of each, flow, gravity etc would be different so a possibility why different jetting!

  2. What can you tell me about my VF500?

    Would think power has a lot to do....120km/h is around the breakthrough wind resistance where you use more fuel than if you were cruising at 110. It's been a good few years, but 750 top speed listed around the 205km/h Mark, had mine around there on clock, but imagine in reality it was around 190 odd... Sent from my HTC_PN071 using Tapatalk

  5. What can you tell me about my VF500?

    My thoughts on plugs are 'a bit lean'? Maybe from intake rubbers..... Second gap looks a bit big? Or is it just angle of the shot? Weren't you also swapping out coil packs and leads? Maybe not a very strong spark.....look up a chart on reading spark plugs and symptoms from colour, deposits etc. Your CDI trigger box may be faulty(dry solder joints) so it works, but under load is breaking down.

  7. What can you tell me about my VF500?

    I'm no expert. I'd be putting jetting back to standard just to start back in the beginning! Then you can play from there once engine is running smoothly. As Jeremy said, those may be too large? Too lean and engine will run hot (burn valves, like a cutting torch) and pop on deceleration, too rich and it'll blow sooty black smoke on hard acceleration(while also washing all your oil off the cylinder walls) and splutter on acceleration(probably as plugs get too wet then fire then get wet again). Vacuum on petcock would be to slow and speed flow depending on demand from the engine, high rpm= high vacuum= pulling diaphragm against spring and allowing more flow. If fueling checks out, I'd probably look at retarded ignition timing? Sent from my HTC_PN071 using Tapatalk

  11. RS850 Replica

    What swinging arm are you using in your swap? have you photo's? CBR 600 F '2000' swingarm is 10 mm wider than the frame opening. I've had two sets of custom bolts made up, next project, I've modified the frame on the right a bit. Sebspeed shaved a bit off the swingarm on one of his projects....

    And I thought there was something wrong with me doing a swingarm swap to the VF.... You're doing a transplant! Awesome, going to be watching progress. Sent from my HTC_PN071 using Tapatalk
