  1. ^^^^^^^^^ What he said. They all do it, some feel it more & that could be down to tolerance variance in the parts build, some bikes have close to blue print spec & some are right at the tolerance limits which may be why some feel more vibration than others.
  2. Never mind the coating I'd be more worried about that ECU being exposed to road crap & spray from the tyre during rain etc.
  3. I think you will find like all this garbage, it's eco noise reduction nonsense & nothing more. The manufacturers try to sex it up, but if it did what they claim they would have appeared Year said before the noise regs forced them on us !!!!!
  4. Sounds like the secondary intake flapper valve opening & closing ! Disable it & then no noise :)
  5. Change everything except the ECU. There are no gains in the old ECU & it will not support the auto choke function of the 00-01 models. The rest will be a straight swap. The O2 sensors on the 01 model can be dropped. Just need to add a 330ohm resistor to one of the O2 power circuits. It would be best to get the PC3 mapped on a dyno, its costs about £150, but well worth the effort, to make the most of your other mods. Your map may work fine, but you will never know unless you check ! There is a lot of wrong thinking about the O2 sensors, they operate in very specific areas of the rev/load range. These being at idle & at steady cruise ONLY. So getting rid of them just costs you fuel. But if you fool one O2 circuit into believing its sending power to a sensor via the resistor mentioned above, it keeps the Fi warning light out. When the bike reaches temp & other measurements to allow the ECU to activate the O2 sensor readings & none are forthcoming the ECU goes into default slightly rich map. It logs a fault in the ECU for each failed O2 sensor, but the light stays out on the dash ! I had mine custom tuned on the semi-stock exhaust with the sensors in, but they are now gone & replaced with a wideband self learning RapidBike racing module. I made up a harness to tap the original O2 power feeds to supply the wideband sensor so don't need the resistor !
  6. I've had one for 4.5 years & 12,000 miles, it's still perfect. I have the race unit with remote reservoir, that is 5 way adjustable. 1-Preload 2-Length 3-High speed compression 4-Low speed compression 5-Rebound It was built for my bike, my weight & my intended riding style, i.e. fast road riding. It works beautifully, I have toured all over Europe in some hot days with no fading. It did a track day last year after returning from Europe on a 33c day, which is rare in the UK, it coped better than me or the rest of the bike, with no fading or loss of damping ! I can highly recommend them.
  7. Just fit a VF750F or a CBR600F2 front end, all the benefits, no drawbacks & leave the rear stock or match with a 750/600 rear wheel/brakes.
  8. Remember that Honda's criteria, will be the same as the race bike, i.e. flat out use. If used hard on track then see how it goes, but if used on the road, regular oil changes should keep it ticking along nicely. Even if used on track, just keep the revs down from silly RPM & it will last much longer. Even so, it will need torn down often to check bearing surfaces etc. It's a bit of a white rabbit, when compared to the Ducati V4 or Panigale if you stick to that schedule, the thing would be worn out in a couple of years just from the teardowns.
  9. If you can't get the plumbers strips, then good old emery paper will do, it's cloth based, so tears into strips easily, but won't tear when in use. Remember to degrease the bright work when finished before painting. Best to run the engine briefly to warm the pipes after degreasing then paint whilst warm, the paint will flash dry quickly on a warm clean surface !
  10. Sorry CR, but setting the ignition advance to ZERO is the only way to rule it out. The map was made on a Euro spec Vtec, that may or may not be compatible with any individual engine. So working around it is a bad idea. Just MO, YMMV
  11. As the Dude says, if you have both bikes, then ride them back to back & see how they feel. The 99 model 49 state bike should be ridden first, this will set the baseline, then if the CA bike does not match that even with more time in the saddle, you will have your answer. The CA bike definately has different cams & ECU, plus less power than the 49 state bike.
  12. I replaced my 5th gen one with a nice carbon one, you may be able to find one for the 6th & 8th gens too 😀
  13. Well you might be lucky, my old 1986 VF500F2 with 54,000 miles on it made 59rwhp on PDQ's dyno back in 2003 :) It had a Predator Exhaust + K&N air filter, running on CBR600 wheels & a Hagon shock. I replaced it with a CBR600F4, which would easily out handle it, but just didn't have the sole nor the flexible V4 engine. I don't know why, but you never seem to be in the wrong gear on a V4 :) PS it produced more power with the snorkel in the airbox, than out, but the noise with it out was amazing.
  14. If you want to swap from 5th to 6th setup, then you need a 6th gen front right caliper, the delay valve on the right fork, you can compare them using online fiche/parts pics.
  15. The one thing you missed is that the VFR SSA is actually NO heavier than the CBR units, because the VFR has that massive 3 piston caliper & the massaive disk to go with it, 270x5mm compared to the CBR's 220x4mm. These components alone make that 8lb difference. But the CBR600RR is a fully triangulated braced swingarm, which is much stiffer for the same weight. But that only matters when flat out on a race track, as the VFR arm is stiffer than many give it credit for. the CBR can carry a passenger, but the VFR was engineered TO carry a passenger & luggage plus the arm was originally designed for the RC45 so its pretty stiff. I'd love to see a fluid dynamics cad stress model of the various arms out there. SSA = super cool look, plus easy wheel changes :) Gets my vote.
