    Definitely bin that.

    Fairings improve aerodynamics which will definitely have an effect on terminal speed. I'd put money on it being faster with fairings.

      My 2000 VFR800 has about 35,000mi on it and the only ways you can tell are scratches on the tank and a filthy fuck swingarm. They are in the dictionary under "well-built"...

        Honda’s VF750 was dogged with reliability problems back in ‘86, so Honda created a bike so over-engineered it need never suffer the terrible taunting its predecessor had; the VFR750. To this day, VFRs are still regarded as some of the most dependable bikes on the planet.

        But dependable needn’t mean boring. In fact, back in ’86 the VFR was a sportsbike so fine that Ron Haslam stuck one on the podium in that year’s Transatlantic Match Races.

        As time went by and sportsbikes got better, the VFR slotted into its ‘all-rounder’ role and has been regarded as one of the best do-it-all bikes around ever since.

        It’s comfortable enough to ride all day, perfectly okay in town, pillions barely upset the thing and the V-four motor blends easy, torquey power with plenty of shove and a dose of character and it’s all just about guaranteed to run forever.

        Camshafts
        Honda fitted dependable gear-driven cams to the VFR, hence the characteristic whistle of meshing teeth. However, the pre-1990 VFRs still suffered a camshaft related recall due to a lack of oil pressure. Honda switched back to chain operation in 2002 on the VFR800 VTEC.

        Tyre Choice
        Original 1986 bikes came with 16-inch front and 18-inch rear wheels. From ’88-on they became 17-inchers, but all pre-1990 bikes have narrow rims (2.5'' front 3.5'' rear) which limits tyre choice. Later models have wider rims that accept more desirable radial tyres.


        Front Brakes
        Despite a slight improvement in the 1990 bike, the front brakes remained a little weak on all VFR750s. Braided hoses are a useful mod. We recommend replacing the brake pads with Honda’s OE pads – they work best with the standard discs.

        Service Intervals
        Minor service intervals (oil and filter) are every 4000 miles or six months, with a more comprehensive service every 8000 miles and a major seeing-to at 16,000. The latter includes valve clearances and will set you back around £325 including parts, labour and VAT. The VFR750 is getting on a bit, so check for excessive wear in the consumables – chain and sprockets, fork seals, tyres, brake pad and disc wear. Check the bike’s service history to be certain it has been looked after properly.

        Gearbox
        At very high mileage (around 60,000 miles, depending on use) the gearbox output shaft can get sloppy: it ends up with too much play in it and gear selection can become difficult. There’s not much you can do – in theory you need a gearbox re-build, but taking account of the age of the bike you’re probably better off fitting a second-hand engine in better nick. Or you can bodge it by putting a bracket on the gear lever output shaft to hold it in.

        Front Sprocket Bolt
        The bolt holding the front sprocket on can work loose. If you remove it make sure you clean the threads, use a thread locking compound and tighten to the correct torque. Buying a new bolt with each chain and sprocket set is a good idea.

        Chassis
        The VFR750 always handled well enough to keep up with sportier machines, but at high motorway speeds the steering had a tendency to become rather vague. Don’t get unduly worried. Honda’s engineers reworked the chassis on the later VTEC model to sort it.

        Suspension
        The suspension is unadjustable, so the only way to improve the set-up is to replace or rework the standard components. The rear shock tends to get saggy at around 18,000 miles and will need a rebuild. Knock a few quid off the asking price if the rear seems soggy.

        Exhaust
        The collector box is mild steel and rots from the inside out before anything else. Check for this problem if you’re buying second hand – if the collector box has started to rot you’ll have to replace it, at which point you’re better off replacing the whole system. Motad do a full stainless system for the VFR750 for £570, (01922) 728404.


        Tyres are awfully thin. Might be hard to buy sticky rubber for an 18" wheel too. I wonder how hard it is to fit a CBR600 or CBR1000 rear wheel? Might just need some spacers and get the sprocket carrier machined. Then you could buy used race rubber for bugger all.

        Change the sprockets too, they're good for 150 mph on the standard gearing so you could drop a tooth at the front I reckon.

        You might get lucky and come across a used system for it, that might help too. I reckon if you do the above then get drag straps to compress the forks you might just get it into the 10's.

          If it was salt flats and 150-200mph I'd agree but this is quarter mile and you're only at those speeds for a couple seconds. Light weight wins over aero dynamics for the low end of the drag racing scale.

          If it was me I'd strip the fucker down.

            Sticky rubber in 18" is not common, I know, my Kat runs 18" wheels.
            There is no way my Kat would be faster sans fairing.
            "Where can we get hold of a Vincent Black Shadow?" "Whats that?" "A fantastic bike," I said. "The new model is something like two thousand cubic inches, developing two hundred brake-horsepower at four thousand revolutions per minute on a magnesium frame with two styrofoam seats and a total curb weight of exactly two hundred pounds."

              Plan of attack is get it running and do a test run as is, then pull bits off from there. The tyre thing probably wont have and effect, a 190 on a 5.5in rim will probably have the same upright contact patch as this tiny thing and with the traction compound at willowbank I doubt ill get it to slip anyways, if I do it could even help me a little as I learnt to drag race in townsville, which has 0 grip.

                Just realised the fork seals are weeping, so a fork rebuild is on the cards too.

                  I think the 190 would put more rubber on the road especially at launch with the weight transfer to the rear and obviously a Supercorsa etc is going to have more grip than ancient touring tyres. As you say though, with the prepped surface at Willowbank the skinny 18 incher might hook up great.

                  Bummer about the fork seals. You going to rebuild them yourself or get someone to do it?

                      Hmmm I might be up for this challenge next year.
                      Best of luck with it.

                        So I finally got back into the shed the other night and changed the oil and coolant, filled the battery with acid and charged it. Got the bitch cranking and it sounds sweet but it wouldnt come to life on start ya bastard alone. A couple of the fuel lines have gone so crispy I snapped them when I took the tank off so im going to get some new stuff and a few reducers (the pump has 6mm fitting and the rest it 10mm) when I get a chance. Once all thats done Im quite confident it would start and run pretty well.

                              Rebuilt the forks yet?

                                nope, been pretty slack, got my RD350 mostly stripped down and then went to thailand to get fucked up then raced scooters on the goldy. Now I have received some head gaskets and stem seals for the race bike (VFR400) so ill be getting into that before the first race of the year. It could take a while to get through this.
