Hi everybody!

I'm new here and english is not my native language, so i hope everthing goes well.(Not living in the country is was born so learning another language at the moment, not english)

my childhood dream! a vfr 750.

But finally i've got one (after 22 years) a vfr 750 f from 1988 EU model, after wanting one when i started driving a motorcycle.

I didn't have the money at that time and got a Suzuki instead!

Now i got this one free, but needs a little restoration.

Normal this like brakes, tires, chain, sprocktes and.....FAIRING! like many.

Most things are no problem but the fairing is a problem and do not want to make it a naked bike.

Used ones are in bad state or expansive.

original new is a no go zone because of the price.

Aftermarket there is one company in France but they do not speak english and the site isn't in english and i do not know people that speak or read France.

Aftermarket ebay there is only vfr 400,800,1200 fairing for sale.

Now is my idea/question,

is it possible to mount a vfr 800 or 400 fairing on a vfr 750 f?

And is this a easy mod?

The engine runs great, no electric  problems.

I just want to drive it for a summer and do the rest of the things next winter.

Hopefully some one has a answer for my problem.

thanks

the bike is SO GOOD it makes no sense to worry about cosmetic fairings.

Welcome to the forum!  Your English is better than many undergrads here in the US...

Have you checked out Airtech Streamlining? http://www.airtech-streamlining.com/hondaz/VFR7501986-88.htm

I'm not sure if they ship outside the US.  If they do, I'm sure it isn't cheap either.  Do you have a link to the French site?  I don't speak French, but I am curious what they look like.  Perhaps someone here may be able to help with translation too.

Not the right bodywork. The '88 VFR750F is very different (although upper and tail are the same and the seat sides are similar).

The US didn't get the '88-89 VFR750F so they only ever have the 1986-87 bodywork.

is it possible to mount a vfr 800 or 400 fairing on a vfr 750 f?

And is this a easy mod?

Possible? Yes. Anything is possible with enough effort. 

Easy? No.

VFR400  (NC30) is too small and the VFR750F (RC24) is too big, VFR750R (RC30) is bigger and fits better....but not well.  Without a lot of modification it looks wrong as the proportions are all out.  You'd need custom subframes, different speedo/tacho and probably different handle bars. 

Not seen anyone try the VFR800F (RC46) but it's very different. Not least because of the side mounted radiators. Although again anything is possible with enough effort.

#7

MadScientist the link that Fastdruid wrote down is the right link to the france company.

 

i did not know off the other company's, thanks for that.

#8

squirrelman i know the that the engine is a good one.

It is running great!

After 2 years it stood still it started with no problems.

This is the honda vfr 750 i'm talking about.

At the moment i've  some small parts i got for free in the bag.

Extra footpins, ignition coils, relays and mirrors.

I'm going for 2 new Avon tyres, and need to change the chain and sprockets, brake disk on the back and front and brake pads.

And a big service.

If get the fairing parts i'm going to lock my self in the garage for a day or 2 i think 🙂

Everything at once.

Hold it! That's not an 1988! That's a 1986/87

Scratch the links I posted earlier. 

#14

Use these. Not the links previous. It is NOT a 1988 model. 

https://www.poly26.com/756-honda-vfr-750-de-1986-a-1987

https://www.skidmarx.co.uk/road-replacement-bodywork#/model-vfr750_fg_h

Also the  http://www.airtech-streamlining.com/hondaz/VFR7501986-88.htm is now valid!

There are lots of differences between the 1986/87 and 1988/89 VFR750F's. Be careful about ordering parts, especially second hand. Lots of breakers/dismantlers do not know the difference.

This is a 1987 VFR750F (not mine)

[image: Image result for 1987 VFR750 -site:pinterest.com]

See how the fairing is different!

The seat sides are different, subframe different, wheels different, exhaust different, indicators different, screen different. 

Brake disks and calipers are different, as are shocks, forks, ecu, carbs, gearbox, even the frames are different!

#16

Yeah i see the difference.

But that's strainge, the papers say the end of 1988.

So the bike didn't have a licence plate earlier than 1988.

Thanks i didn't know the difference.

Idid see the difference and i thougth that it was from 1990 and on.

#17

The tank is also different!

Now i need to check all the parts again hahahaha

#18

Fastdruid,

Nice bike!

But how different kan the engine be , i tought they stopped with 750 and did start the 800 instead.

Is it the quality of the engine? sice?

The frame difference i see, because the tank is bigger so far i see.

#19

Tank is actually i believe the same (apart from paint). 

Frame...functionally the same but 88/89 made from fewer larger parts (less welds). Centre stand different.

Wheels,  18 rear/16 front on 86/87, 17 front/rear on 88/89.

Forks, 37mm on 86/87, 41mm on 88/89.

Rear subframe totally different, pillion pegs on alloy hangers on 88/89.

Fairing 3 piece on 86/87, 4 piece on 88/89. Can be made to fit but the mounts are all different so not a straight swap. Seat sides different but i believe. 

Seats kind of interchange, you need to modify one to fit to the other but cant remember which way round! US clocks different (round), 86/87 EU clocks  *also* different to 88/89.

Screen adjusts on 88/89, fixed on 86/87

Engine... 88/89 has bigger inlet valves, bigger carbs, different cam gears, different cams, different followers, starter different (and idler etc), gearchange all different, alternator different, both left and right covers different. Gear lever comes out in a different place so not even gear levers are the same! Plus different pickups,  different ecu, different tacho! Exhaust totally different. 86/87 Is 4-2 with a link pipe,  88/89 Is 4-2-1-2.

Also 86 has cam sensor,  none of the others have

Fastdruid,

Although they look almost identical almost every single part is modified on the 88/89 from the 86...Gearbox is out of the RC30 (only the ratios differ). 1990+ has different heads but the bottom end is pretty much the same as the 88/89 (only major bottom end difference is the output shaft is longer).  Main difference in ownership is the 86-89 need valve clearances checking more often. Just as reliable until you get to the VTEC with chain cams. 

No real difference in power between the late 88/89 and 90-97 tbh. Condition is everything. The 750's make more torque than the 800's low down and the same as the 800's peak. Only difference is the VTEC revs higher so makes a few PS more.

Realy cool this info.

Funny how little the difference is on the models (PS and Nm)

And i also understand there is more to know and learn.

I did know the cam chain driven engine is more vulnerable than the older types.

But didn"t know you can't change parts between the engines.

What is also funny, my wife did have 2 vfr 750 before we knew each other.

sadly ze did crachs them both...

But she may not take this one for a drive when it's done.

'86/87 is the lightest fastest VFR. 🙂 

You do need to work out which yours is, '86 or 87. There is an easy way as yours has no fairings atm. Look in the middle of the V, in the middle of the front cylinder head and see if there is a cam sensor with a cable leading away from it. 

The 1986 has a cam sensor. 

The 1987+ does not. You can see where it would have been but the head is not machined for it.

Here is a 1986 front head (upside down obviously) with the machined hole for the cam sensor in the "gear tunnel".

Honda changed lots of little details every year.  Sometimes you can swap, sometimes you can't.  Some you can swap but need lots of other parts swapped also. 

Example, you can use the later ECU on the early bikes. The starter (sprag) clutch (part 5) with the triggers on is a direct swap...but the the sprag clutch is different so the gear doesn't fit (3)  so you need that and then idler gear (1) and starter is different.

Or the alternator...the crankshaft is different between 86/87 and 88/89, the flywheel fits this way round on the '86/87

[image: Honda MOTO 750 VFR 1986 VFR750FG Engine GENERATOR (1)]

and this way round on the 88/89!

[image: Honda MOTO 750 VFR 1988 VFR750FJ Engine GENERATOR (2)]

Also the VR sensors are different... and the tacho is different, you can use the '87 tacho with an '88/89 ecu but an '86 needs a new tacho!

Fastdruid,it sure looks like you know your VFR's inside out, years of practice I assume

Only the RC24's. I've had my 88/FJ since 2003 and ran it as my only transport for years. Commuted all year round on it. Rebuilt it ~10 years ago with a 89/FK engine (primarily as the exhaust broke, a bunch of exhaust stud snapped on me taking it off and two engine bolts seized and needed drilling out. A new lower mileage engine was easier and cheaper).

It looks like you did have a little job to do when you did change the engine.

How much time did take to change it?

And did you fix the old engine afer that also?

#26

Easiest way to remove engine is to lift the frame off! Plus it was a good time to do a bit of a refresh in general. It didn't take long to do the work... but it was off the road for 5 months.

Old engine is sat in the garage. Turned out to be quite a bit down on power compared to the new engine (old one had 67k, new one 30k). Plan is to take it to 840cc... 🙂

#27

Checked the dates, Off the road 7 months! Exhaust blew 4th Dec.

Didn't touch it for a month. Took the old engine out end of Jan. New engine in start of March. Discovered replacement engine had exploded a clutch plate and was filled with bits.

Didn't know what kind of damage it had caused and so took it back to the breakers for a refund.

Bought another engine...turned out to be a VFR750K not a VFR750FK (5spd, restricted to 75PS although unsure if physically restricted)

Didn't find another reasonably priced engine for 3 months. Picked up another one mid June and went from this on the 14th to all back together by the 21st [image: OEq3Z4mlPq-9wpA2e66UvZYKzBzpoXNQ7x1b7ju43L_kIgGmyU1v1_I0qmV2d3xC4hHSzqy0IlGNTcsDc-hmA-HHAti8nkWbIDmqx50fOIaPuxriAi-XgAzB7NhAUi86D2HEal8wr_YC2pqgThArbZ5isb34kiUoK6uA2W5yWmiQxRHrOir7dkigXASy6lTIAPvFZ5XSGDtLdvLBafa3T1NZuWXtoTQTKZBOUJD8508NhdXyYM13g6Ap66XjZuc5uNKiw8FdENYpNv-JDxRx2lX1eJfjfJTicmzDChKBUEl5q4JDjhEqiqY0ZqrRU7RqfwStfXPcTRtbpTZf4_JqKOxsgrvesHTWr3MNGk28kUgIn6oCxgcT7UHxg-NZ0hiRTvo0RHJYtNB9yruhtovgUvKNdC5VydsiJYSbf0_73uvKNoPVJnkig3mag5ZMMa2eau9FVQQMfAZ1h485jzSMHasPqeNOX2cfIVdPX66hrmOE0qW8qfmRkezd1U3i0d6VjvE5YAtIZVItXgdg4A56zmVC2cWlaq8hRkPA4twpPKPvlozNbSb7YW_4qmHcW7M_mAsgnfdlTImn5qJgjYKMwDcmFrr2lcv5cNBtweupB56ub-SiyLxV6hMEM5PnA0M6Rirrxlb9IaJ5mTbzAQRaeI0RIYtKEvdt=w1251-h938-no]

So about a weeks work but spread over 7 months and a bunch of grief. 

As well as the exhaust I did overhaul the brakes (new pads all round), forks, replace the rear disc, chain+sprocket, shock and swap the rear brake line for braided. As well as replacing the anti-dive bearing and cleaning and lubing pretty much everything else.
