VF1000 / Re: VF1000R oil burner
« Last post by vf pete on March 22, 2018, 08:02:34 pm »
I had same thing last year with the boldor I rebuilt, it too hadn't run for a number of years before I got it started, when I did, the engine ran smoke free with the old oil in and had good compression, but when I put new oil in it it blue smoked, I removed the exhaust to have a look at the exhaust valves, they had previously been clean and dry, they were now showing signs of oil running down the stems, the bike still showed good compression, so I assumed it was just the stem seals that needed replacing, BIG MISTAKE, after removing and rebuilding the cylinder heads, new stem seals, re seated valves, it still blue smoked..
So, removed engine again, complete strip down, turned out to be the oil scraper rings stuck in, the compression rings were only just in service limit too,
My thoughts are that the bike ran smoke free with the old dirty oil in as it couldn't get past the oil ring, but the new clean oil did, and I also think oil getting past the oil ring gave a false compression reading..

finally, after all that, I started the engine, the blue smoke was swapped for grey smoke, which turned out to be the pilot screws which needed adjusting.

Hi longclose,
Due to not running for 4 years, it's a possibility that your oil burn situation is due to stuck oil rings. I've encountered this before and found that if you remove the spark plugs and inject an ounce or so of Marvel Mystery Oil in the combustion chamber, hand crank the engine a few times, leave sit for a day or two, there is a chance that the oil rings will loosen up. After this you can install the plugs and start the engine and just let it idle. It will smoke some as it burns off the MMOil. This process may need to be repeated a couple times. I also drain about a quart of oil from the crankcase and replace with roughly the same amount with Marvel Mystery Oil or a quality automatic transmission oil (is highly detergent) which will get to the underside or the oil rings.
As 'paul 810' discussed there can be issues with the carb float needles not seating properly and dumping raw fuel which will make for a rough idle and cause smoking.

Sales and Wants / Need: 85/86 VF1000R rear intake cam
« Last post by Faxe on March 22, 2018, 08:47:10 am »
Hello Folks,

I've got two sets of spare cams. Due to bad luck both rear intake cams have pitting. So I'm looking for a good cam to rebuild my spare engine.

Murphy says: If you have a working replacement, the build in engine won't get broken  ;)

Both front intake cams look good, so if anybody wants to change, this is also possible

If anybody has information about a Company, reworking cams I would also be interested in that.


VF1000 / FF screen
« Last post by Bart on March 21, 2018, 10:59:50 pm »
Due to some ear/ wind noise issues have have developed over the last year I want to try a cut down screen on the FF but don't want to ruin the one on the bike.

Has anyone got a damaged/spare one they don't want/need?

Hi longclose first I must ask what the mileage is and these bikes are not renown for smoking badly, my fe had bunged up carbs so I removed them and cleaned them and refitted them and when I restarted it she was running okish but was not quite right and the bike smoked a bit and kept on smoking even after 40 minutes of running, so I replaced the plugs and leads and recleaned carbs and found one carb was flooding directly into the engine so bought new float seats and valves and restarted her, the bike smoked again for about 25 minutes but found this to be old fuel in exhaust system mixed with old carbon burning off, usually worn valve stem seals will cause it to initially smoke but would soon clear, rings usually when worn will smoke on the over run and during gear changes,, I would replace carb float seats and needle valves and have carbs sonicly cleaned I could do the carbs for you if you remove all parts as long as you are in England, hope this helps

I took photo's of the original paint work, printed quite a few out on A4 black & white, then took measurements, I wrote the dimensions onto the pics.
One to watch is the front side fairing, where it lines up with the tank decal on both sides, its easy to get it misaligned, even though measurements are taken, offer the panel up to the tank before decals are firmly pressed down, just for a visual check.

sorry it took so long to respond, I couldn't get back on the site ::) :P

They say that time flies when you're having fun - well I must be having a BLAST 'cos this forum has been around now for 14 years and the time sure has flown by!

We've had a few updates over the years and we migrated to this forum software (SMF) 5 years ago. SMF is now showing it's age, it's not responsive - which means it doesn't work well on mobile devices, it looks dated and we are still getting problems with spammers.

The whole concept of a forum is as they say very "last century" with the focus now more on discussions. Whilst we all love our old timers here and our 30 year old Hondas are still pulling strong - the same can't be said for old technology... So, the time has come for another upgrade!  ::)

I am working on migrating the forum to a Discourse platform which will look like this

It's running on cool new tech, and has lots of sparkly features to keep us chatting about our VF's for the next century or so!

I will give you another heads up when I am ready to go live so you can be more prepared for the impending doom...  8)

Kind Regards

VF1000 / VF1000R oil burner

Good day Guys,

I have just joined the VF1000R club by purchasing a project, the bike has been stood for probably 4 years before it was last started. I re-commissioned the engine by removing the carbs cleaning and re-fitting, lubed the cylinders, cranked the engine by hand to check it was not seized and/or had stuck valves. I then cranked the engine without starting to get oil pressure up. Compression was checked all to be a minimum of 9 bar (130 PSI) and plugs refitted.

After this the bike fired on the button, it was clear after checking the water temperature that the bike was burning oil at any RPM and not just on overun (oil stem seals). So before I pull this motor apart I just wanted an insight to what other owners have experienced with the Vf burning oil. If it is the bores/rings what are the options (I know I can get standard rings) also what are the options on mains and big end bearings which appear to of gone out of production.

Any thoughts/opinions greatly appreciated to a new Vf owner.

Good day/night to all the members on this forum, thought I would follow etiquette and introduce myself as I know a lot of people get offended in jumping into forums as a newby without an introduction.

So after the kids of all left home 3 years ago I started after 30 years buying projects and restoring them for my own personal collection, as a precision engineeer/instrument maker I have been undertaking the projects myself. To date I have restored  2 x CBX twin shock and 3 x CB1100R, I now undertake restorations/re-commissioning as a pastime and for beer money!

I have searching down a VF1000R for some time now and had been looking for a project, a couple of weeks ago I secured a package deal of a VF750F a CB1100RC and a VF1000R project. I will put a post up of the VF on a separate thread as I have an issue with it being an oil burner!.

Here are a couple of my restorations for your bike porn addiction like me.
