They were a nice bike. If you have a workshop manual ... most of the strip-down / rebuild you could do yourself. If you haven't ... Hillside books in Dunedin will have / can get one. There are some (not sure about your model) on this site available for download. Or find a download yourself.

Thus ... those that do head / valve work get the bits they're best at. Those that do the re-bore get the barrels ... and costs get cut dramatically.

Is the gearbox ok ... ??? and how bad is the engine ... ???

Hi there

thanks for that . Gearbox seems ok had the bike running /changed oil and filter and noticed a rattle , took the bike for a ride the rattle turned into a banging then bike stopped wont turn over , can hear the starter trying to turn the engine over sounds tight to me. Paid $ 500.00 for complete bike hadnt been run for eight years . bike has no warrant but live plates ... the bike still has full fairing and in pretty good nick.. is it worth a rebuild????

Yes it is worth it. As I recall ... it will have gear driven cams ... does it not .. ???

Can you turn the motor over backwards ... ???

Hi There

This model has chain driven cams .. I thought it might be cam chain slap at first ... I put it in fifth gear on centre stand and tried to turn the back wheel by hand it was really tight. I havent seen many of these fully faired models around just trying to work out how cost effective it would be to rebuild .. everything else on the bike seems good possibly a bit of leak from the front forks and the odometer doesnt work speedo goes .... how much would these bikes be worth in good going order??

Yes so I found .. (googled it) This sound like yours .. ??? Do the rebuild right and it will be worth it. There is not many left. I don't think they were imported into NZ in great numbers.

Check with a local bike shop what costs for the head-check/valves etc and re-bore.
Might have to see what caused the "Bang" first. I'm guessing cam chain (bearings or similar ???) let go


VF1000F2

Following the release of the VF1000FF in 1985, a fully faired version was introduced, and the VF1000F2(F) was launched in April 1985 as a sports tourer. The 116 bhp (87 kW) F2 included the same styling changes we had seen in the VF1000FF but Honda added a more aerodynamic full fairing which covered most of the engine, and changed the seat design to improve comfort for rider and passenger over long distances.

The F2 has the name of the French 24 hour endurance race "Bol d'or" across the top of the fairing behind the indicator, giving this VF it's Bol d'or nickname. An extra radiator is included to assist cooling and is integrated into the "wind tunnel" designed fairing. The fairing, designed to increase rider comfort and reduce drag, has a built in ventilation system and twin storage "pockets".

The cockpit was redesigned too with a centrally mounted fuel and coolant temperature gauge, new style speedometer and tachometer with yellow backgrounds. The twin headlights first seen on the VF1000R are also included on some models. Suspension and braking specifications remain the same as the VF1000F/FE. Engine and frame modifications were carried over from the development of the R and FF models, but the F2 still had chain driven cams.

The VF1000F2-(F/G) was discontinued in May 1986.

Pull the plugs out and put a little light oil into the cylinders ... and leave it for a few days and try again.

I have heard such things about him. Specific places for specific work needed. Not necessarily motorcycle places.

That's why I suggested getting a workshop manual. Nothing like having facts in front of you (with pictures)

The Honda dealer still in business ..???

Yep the manual seems like a good idea ... so you are saying I could get a workshop manual strip it down my self and send various bits to various peple to get done etc??? havent been into the local Honda dealer in Invercargill the Local one in Winton really just deals in farm bikes etc

Your hourly rate will be less than ANY workshop. Otherwise it may not be worth it. But I've rebuilt a few four cylinder bike engines ... read carefully ... and they explain it well ...

Make a few phone calls ... ask a few questions. (I spent my childhood in Wallacetown by the way)

Do some research, there's a few tricks with the oil feeds on these things. I can't remember what off the top of my head, but I'm pretty sure the main one was moving the oil feed to the head off the gearbox gallery...or something.

its probably the bottom end,a conrod bearing most likely.

I hope you have deep pockets as the last one of those I rebuilt for a customer was around the $3000 mark all up.

good luck.

yes i got qouted 500.00 for the con rod on the crank to be cold welded for vt 250 might still do it

if i get myself another job, so guess in theroy if you did the rest yourself you have to get the bearing

shells that go between

I have to agree seems that what the problem will be

As with most of the Honda V4's of that era, it is likely to be the crank - and most likely a big end. Honda didn't finish the oil holes very well where they break onto the bearing surface and they pick up bearings. In my experience, often this doesn't mean a new crank...the material and surface finish Honda used generally means the crank doesn't crack. I've cleaned up several cranks with good results.
They are however a complex and time consuming motor to do....hence costly....

There is a guy on this site that imports engines from japan. Look through the engine related forums (use search .. Engine imports) The numbers may not match ... but may possibly be a cheaper option.

After you find out what the engine issue is with your bike.

As an observer of old bikes on trademe over the years there crop up from time to time and a fair few have survived in reasonable condition. I think back in the day people were a bit leery of putting too many miles on them and they seem to pop out of barns semi regularly.

If you rebuilt the engine yourself (assuming not much wrong) and tidied up the cosmetics as you went (assuming its in already better than average condition) you might just break even... If you paid someone to rebuild the engine for you an hourly rate I doubt it very much.

If you think this could be a monetary profitable project then I'd say you would be very wrong. It would however be a very interesting project that could result in a very interesting and capable bike and some excellent learning experience. You will spend more than its worth in a straight sale though... It nearly always works out that way

If you're looking to make a profit, I highly doubt you'll manage, unless you do some deliciously dodgy work to it.
I'd rebuild it though, always liked those V4s.

F2 and FE were both great bikes , the F2 was a prefered model becauase of the full fairing. I had a CBX750 F2 which was similar in design (but inline4) and i always enjoyed working on them. The CB1100r and the VF1000R are my fav bikes so i agree to rebuild it and preserve a great bike for the future.
I seem to remember the oil pump or starter gear gave issues but i lost my memory a few years ago .
Good luck and keep us informed.

VF1000R worth doing,Gear Cam Drive and all

VF1000F means basically a waste of time unless you happen to love it for some reason

your call

If you get it going you'll have potential kudos points for telling people that that F2 model won a TT in the hands of Geoff Johnson (85-86?).

Sorry anorak moment! He he.

Seems no one will pick up the bonus anorak point by pulling me up about it being the Bol d'or version of the F2! He he.
