 |
|
Well, I found it in my own shed.
Since both my Enfields seem to be working, I dragged out my "old" 4th Gen VFR750. I'm currently riding a 3rd gen one which I bought because the "old" one was in such an advanced state of grottiness, it was starting to become unreliable.
it occurred to me that the 3rd gen isn't as nice a bike as I remember the 4th gen being. The 4th gen was physically larger, comfier, bigger tank range and all round quicker. Not helped by the fact I got humped on the 3rd gen which is a restricted Japanese import. I've swapped out all the parts I can for UK spec but I suspect there is something else more fundamental like compression or igniotion advance holding it back.
Anyway, the 4th gen was ridden in all weathers, year round for about 7 years and stored outside. I stuck it in the naughty corner of the shed 10 years ago and have been robbing bits off it ever since.
The first job was to jack it up and fit a front wheel, then drag it out of the shed which was no mean feat in itself!
Large amounts if ming detected in this sector.

First thing I did was scrape the worst bits of cack off with a screwdriver then liberally gunk the whole bike and hose it down. It's still grotty but doesn't have actual lumps of crusty muck dropping off it all over the place.
This is not going to be a minor or cheap undertaking. All the front plastics are smashed beyond hope of redemption (and I'm quite handy with fibreglass) but I'm reasonably confident the plastics I have on the 3rd gen can be made to fit. If it starts looking really tidy, I might spring for an aftermarket fairing for it or I have half an idea I could bodge an RC30 race fairing onto it (which are available quite cheaply in coloured gelcoat).
I'll also put the sorted out suspension and brake parts off the 3rd gen onto it. which will hopefully go with a bit of imagination and bracketry. ____________________ “Rule one: Always stick around for one more drink. That's when things happen. That's when you find out everything you want to know.”

Bloody hell, and I thought mine was a horror.

I'm sure you know better than I do, but I thought with a flatslide carb (and slide carbs generally) that the slide was operated directly by the throttle (and there's no butterfly valve), and on CV carbs the butterfly valve is operated by the throttle and the slide is moved by the vacuum pressure of the airflow.
But I'm sure that on my 4th Gen 750, the throttle operates the butterfly valves, so which bit of the above am I wrong about? ____________________ Current - '94 VFR750FR, '00 VFR800FI Previous - '10 Street Triple R, '92 MZ ETZ301, '05 TTR250, NSR125R, KMX125, "Honda" Win (chinese copy of an old Honda design with a C90 engine)

I'd imagine if you wanted to get to the top end quickly flat slides are the way to go. That being said the 4th Gen you picture is more a "square slide" - probably the low end would be too choppy with a flatter slide  ____________________ Husqvarna Vitpilen 401, Yamaha XSR700, Honda Rebel, Yamaha DT175, Suzuki SV650 (loan) Fazer 600, Keeway Superlight 125, 50cc turd scooter |

Fascinating thread - I will be watching this one closely. I look at my (admittedly more modern) VFR and the thought of stripping it down to this level I find mildly terrifying. Much respect.  ____________________ TG. |

The Japs are pretty good at assemble and usually this translates to the disassembly.
I've taken apart a fair bit of my XSR and it's all pretty logical, service manual not really necessary. The ol' Triumph, not so much  ____________________ Husqvarna Vitpilen 401, Yamaha XSR700, Honda Rebel, Yamaha DT175, Suzuki SV650 (loan) Fazer 600, Keeway Superlight 125, 50cc turd scooter |

Got most of the exhaust on. First job was to oval the holes slightly in my new flanges so the studs line up. Top is the original, middle is how they came, bottom is with holes ovalled.

The stainless was hard as hell but a tungsten carbide burr made short work of it. Most of the burrs for sale on ebay which say they are tunsten carbide, aren't, they are some sort of high speed steel. A solid carbide burr has a greyish lusture to it and will blast through damned near anything and isn't particularly prone to overheating so you can get aweay without loads of cutting fluid. Biggest clue is the price, if you are getting six of one sort and one of the other sort for the same price, the single one was the solid carbide.

Found some nice brass acorn nuts to hold it on with so these should fly off if I need to remove them again.

If anyone is getting their head in a spin fitting VFR exhausts. The header pipes cross.

I have a high level micron link pipe kicking about somewhere. It'll need a bend with two diameters fitting between the mid section and link pipe but I can't measure that until the subframe is fitted so I can see where the end-can lands up. Plenty places doing bespoke exhaust bends these days. Might even see if they'll tig some loops on so I can fit it as a sprung slip-joint.
Proper paint stripper arrived.

These LPHV spray guns are fantastic for painting small things. I'm even contemplating doing the fairings. Absolute minimum overspray compared to the old spray gun I have. You can legit just move stuff a bit out of the way when using it rather than sheeting everything in the vicinity.
https://lh3.googleusercontent.com/pw/AM-JKLV97gvgjAZBAVeDcerQgwmPs9A6C2qdYly5168QhfS2K9osCCFOjoH_0sLydT_hcgX6DnovJWhIjCyDBxLtJKuhxLgPX0KBWOaKCOGM-vXjN5IVYiAdPXNjT-_ZZTaXqiPNG30yVDGRJoxqaiJSUh1P=w1378-h776-no
Quite a good result considering the starting point. ALthough you can't really see this once the fairings are fitted anyway.

Done the subframe too. Again, this is covered up. It's supposed to be silver but I have a tin of Massey Ferguson gray so I used that.
https://lh3.googleusercontent.com/pw/AM-JKLWArYmIZwq9z--unDBVt0Ur4BRrS1B4vGTjB7qS9-E41hV7Gz5Ww3gQCIszl6p2_xqkxF5eQnIeM5ICXGobv6xanSQTTsrG5Nil0F54lSHD1IRvLXmMve4TSa5xbFCxVWCa3t10stWZDxPtiE2Xx7B-=w1378-h776-no
probably enough for one day.
Once the paint's hardened on the cover, I can refit the clutch with the new oil pump chain pending finding someone to re-build a clutch basket (I have a spare now). Then it'll be in a position where I can get a pressure washer at it and get rid of the remaining crap before starting reassembly.
Shock off the 3rd gen isn't going to fit, which is a shame. It's longer. I used CAD (cardboard assisted design) to mock up a new triangular plate that would keep the geometry but account for the extra length and it's not going to go, part of the dogbone would foul the exhaust. From cross referencing aftermarket shock part numbers. I could fit a shock off a VFR1200 or an early VTEC VFR800. I'll refit the original one initially, they are easy enough to swap out once you know the trick. I don't recall there being anythng actually wrong with it. ____________________ “Rule one: Always stick around for one more drink. That's when things happen.

Aim for today was to get the bike in a position to roll it off the ramp and pressure wash it. I want to take it in the van to the industrial grade carwash up the road. i also want the ramp for a day to do stuff to mrs stinkwheels new scooter.
New oil pump drive chain fitted, clutch and starter clutch refitted and torqud up.
https://lh3.googleusercontent.com/pw/AM-JKLUV170CUI01lcaXNUM0V_erOgola2Upp84dphzthjKl8XOboqEIojp82UlG7UyhHZ-7QK-qsqFKgn4hC1VbU6ZBxLTZO4qGrYnMeQlDiJ4yTODNIkiN_IyWFG4T_SwrNxnsUNXtlYy7cLbYxoOkjDT8=w1378-h776-no
If the delay has had any benefits, it's that the paint on the cover is fully hardened. New gasket.
https://lh3.googleusercontent.com/pw/AM-JKLUiMqB2AihFkQ2amlnFSBvJfoLx2s6yDki3R7PT6LwIjMRNtaenKQXrzz6X_2LQNCDrOhKmJtPPj0jJWX0LzGiNzzovYNIc9kp9nROFn-VpnNYEuyiJoFRp60kP8TlFt4TUPpdvunr69gnPydQPLcWw=w1378-h776-no
Swingarm is remerkably easy to remove and refit, again providing you observe the order of operations. You'll see a threaded collar sticking out of the frame in the above picture. You hold the swingarm roughly in position then screw that collar down onto it until it engages with the bushing on the swingarm. That holds it in place. You then slide the pivot bolt through which engages in the collar. You tighten the collar down using the pivot pin with a torque wrench to a specific (and surprisingly low, 19ft/lb as I recall) torque which grips the swingarm in position and preloads the bearings. Then you screw a castellated nut down on top of the collar to lock it in place. The main nut on the swingarm pivot doesn't load the bearings at all, it just holds the pivot into the frame.
Surprisingly, the chain looks ok after a good soaking in old engine oil and a scrub with paraffin and a toothbrush. it was all yacked up with lube and road dirt but isn't rattly or corroded.
https://lh3.googleusercontent.com/pw/AM-JKLU8bg6pc_2Y3CuXBoovMunw6Gq3JT_3Ve1i1Sdr9XL-qVmj8juZI76062l2GQlSuJdrf61qwyy2mtc94iuK-wFf2M3czrJ94NUGkCgtWg5KSj-h-FAVn80n22Azv_fNoOki732ZJcjjVAJvrrI-MLpJ=w1378-h776-no
The shock drops down from above, you put two of the bolts through one of the triangular plates to engage the shock and dogbone then lift up the swinger and insert the third bolt. Then it's just putting the scond plate on and tightening the nuts. I've had this job be much more of a rigmarole on other bikes.

Manky rear wheel back on temporarily (I have a powder coated one to go on it later) and it's ready to wheel away and give it a wash. I've deliberately left the subframe and sprocket cover off so it can all get a good blast out with the hot, soapy pressure washer.

Your prowess at this is impressive .
The use of brass nuts is something I hadn’t thought of, it just makes sense.

I can sorta see it with a shaft drive but does a single sided swing arm offer a massive advantage on a chain driven bike?
