Vf500F2 Aka Mbd Incubation Period At Least 52 Years

696 posts in this topic

Dutch CL had a set of "race bodywork" for the RC51 "from Japan". So I swung round to have a look. 

Hmmm, all panels still properly wrapped but the shipping paperwork said "Hongkong".... :-)

 

The seller (the father since his son was in hospital follwing his wreck) looked puzzled... "Hongkong is Japan no?"

I am pretty sure he feigned ignorance, but we agreed a price we were both happy with....

Plenty horror stories on the web on Chinese bodywork, but one wintry/bored day will test fit it.  In the attic space now, hope I never really need them :-)

When you said tasteless tank pad I envisioned something a little more appealing for my junk to run into.

And here's to VeeferMadness who sent me this "ward off evil spirits bell" years and years ago. It served me well; in fact saved my bacon in Lithuania......

Accompanied a 4th gen friend who had been tinkering with his carbs's internals (dynoyet kit) for a dyno run this morning. Yeah it rained persistenly, but there is no bad riding weather is there? 

 

Only bad clothing for the occasion!  And gear I have plenty!

While there, I decided to put the VF500F2 up for a run as well. Just to see how well a 31 year old bike performs.  Never really saw a lot of VF500 dyno charts posted anyway, only reports that the 70BHP claims by Honda were "optimistic"....

But if we take a 10% difference from rear wheel to crank...... :beer:

As the OEM muffler design doesnot allow for the CO2 probe to be "in" properly, we skipped the A/F measurement

 

 

 

V4rroooommm!!!

 

Looking back at the vid, you'd think he missed 6th gear, but he starts each run from 2nd:goofy:

100% stock methink

 

 

 

But I bought the bike used and have not had the carbs serviced/opened so cannot be sure if anything was changed here....

Testament to the build and design. You would be pushed to find a modern 500 pumping out out anything like much power. Just a pity it's a bit fragile in the valve train area.

31 years is a long time...

The OEM bodywork looks nicer so that will stay on; especially the top/nose fairing.

My sides do have a few blemishes, but the gray wing color matches perfectly with the tank.

But, having saying that, I've been know to change my mind (aka get in touch with my female side :goofy:)

 

The kit came along at a very good price, a price I could not resist :cool:

Useful info. Gives me something to aim for. Possibly that dyno was a tad optimistic though.

 

 

 

The 4th gen (open exhaust, K&N filter, dynojet kit all done by the owner, not a tuner) produced 97 ponies so I don't think that dynoyet bench is overly optiimistic. But benches do vary, as does altitude (the town is about 8 metres over sea level) etc as we all know

As you spotted there is so little dyno info for the VF500F. A google search brings up bugger all. The chart I posted was from the original reviews way back.I suppose these then became the "truth".

Your run is as valid as anyone elses. Have you managed to measure the top end on it? The best I have ever seen on mine was 183km/h on a GPS. Mine definitely doesn't deliver 59hp though.

 

I might try and get mine tested..

I will need to find an excuse (as if I need one) to break the Dutch speed laws now......  "I am sorry officer, but this Jeremy character made me do it.... :tongue:"

Or nip across the border into Autobahn country :goofy:

Here's another dyno run from way way back. This is for an 1984 version with the 32mm carbs and different heads. 55hp, which is close to what Cycle got when they tested the 84 version (they got 53.2hp).

Not bad at all. I feel a challenge coming on..

The Mechanics reviewers got 123mph (198km/h) from the one they tested with 55hp so there or there about.

That was at a test track too.

Well, despite what they claim, the Autobahn is no test track :-)

 

9/10 attempts I had to abandon as I was approaching traffic... Earlier, doing 130kmh I nearly got wiped out (by a dutch cager; the worst drivers in the world behind the Americans....) not checking his mirrors and move into my lane....  :-(

The Autobahn really depends on which one you're on.  The popular ones are not only very crowded, but absolutely chock-full of restricted speed zones that go on for miles.  And don't get me started on the "Lärmschutz" speed limits!  Besides which, of course, when I'm in Germany on a bike it's usually loaded up like a camel, so testing its top speed is a bit of a pointless exercise!

 

Ciao,

Wow....  interesting data from my Garmin device

 

Knipsel.JPG.a0f677a7be9527f51baebb193df1a1c2.JPG

 

3 clicks to get from 160 to 190 and one minute. 

 

The Garmin tracks time/averages per section, making is impossible to determine "real" acelleration. Took her a minute

But she is no torque monsta! One day will check out the SP2
