Honda VFR400R Restoration

[Ancientmariner]

So I bought this a while back and although it will take years I am going to start a rebuild (front fairing already removed)

[ATTACH]429966[/ATTACH]

When I got it it wouldn't start so after a bit of fiddling found choke cable snapped. Replaced this and still wouldn't start. More fiddling and found the fuel line cracked and leaking air. With that fixed it starts, however any quick throttle and it dies. So I suspect the main jets on the carbs are blocked.

But for now it's in the air where it lives with the front forks removed which I am stripping, recoating and then rebuilding with new seals.

Manuals for this bike are near next to none existent, as are spares so as a first bike restoration it's going to be interesting.

Forks now stripped and about to recoat.
Found a few parts I suspect missing from the forks though there are notable differences between left and right forks.

So the bit I forgot to add.

The chap who had this before me made a few changes which add to my jobs list.
The rear wheel has been changed to a CBR600 wheel, hence sprocket and rear brake discs are also different.
The front wheel is also from a CBR600 but hasn't been remachined as yet. I have a VFR400R front wheel which I will use for the minute but I intend to chat the the who bike back to stock VFR400R and will have CBR wheel set, discs and sprockets as a spare set. CBR600 has a wildly large tyre selection available bit to start with I want a correct base.

Other jobs:
New chain.
New exhaust (scratch build).
Forks rebuild.
Carbs rebuild.
Full clean.
Repaint.
Front wheel to fit.
Brakes to bleed and hoses to change.
Oil filter and oil change.
Seat to recover with different colour leather.

Will be a steep learning curve!

Currently making a manual from combining drawings and parts list in an excel sheet so I at least have some information to use.

Ambitious project. Good looking bike.

Nice looking bike James. As to manuals, is this any good?

nice project......keep us updated

[Ancientmariner]

Thanks for the input all

As for the manual Tim that's what I have but it's basic, very basic. I bought a Haynes manual for the NC30 think it would be a lot more similar than it is but alas, I guess it's good as reference.
That one you've sent me I am currently combining with the drawings from a Dutch parts website which has very good drawings. Thanks as always for the info. I was amazed how little there is for this bike, I guess namely as it was import only and also 34 years old now!

Just resprayed the forks today, gone for gold as opposed to the metallic brown they were.
Might whip the carbs out tomorrow I think.

Sorry it’s no use. I looked for workshop manual and manufacturers service manual but that’s all that came up.
Was it a home market only bike then? If so, perhaps you can find a Japanese speaker that could google it? Not sure if there any on here, but worth a crack.

Thanks for looking Tim, I think that's an NC30 manual and it's in a few places. There's also one available if you dig very deep which says it's the NC24 but the suspension is different.

I have spent most my day typing parts lists up and printing the drawings so I have something to work from.
Just annoying really as I'd love to have a Haynes manual for it!! Also yes it was JDM only, hence parts are impossible to source.

My other half speaks Japanese but I am even struggling to find the original Japanese manual!

Can’t be this one then…..

Unfortunately not Tim, the NC24 is 1987, the it's Haynes is for the NC30.

It's soul destroying when you think you've found one and then realise it's not the one.

One good thing I do have is a generic 1987 Honda service manual, not for specifically bikes but it is good as a helping hand.

It's certainly an experience having to pull info and just work it out as you go along.

Not surprised really. It would be a bit odd for Haynes to make a manual for a grey import :tongue-out3:
Just out of interest, have you tried contacting Honda direct? Might be worth a crack.

My mate had one of these out in Germany. I had to look after it when he went to the gulf on det for a while. Whilst i found the lack of power compared to my CBR600 very noticeable, i do have to say that it was fantastic around the twisty corners and really a lot of fun. Not good for autobahns though lol

I just saw it on eBay and thought it's a nice ornament.
It's the smallest bike I have currently as everything else is 750 or over.
Like the Rothmans colours on them and wanted a doer upper.

This is an option and no I haven't yet, will do tonight and see if I have any joy.....
