Not sure yet, the underside is/was very dirty with old grime so I need to get my sherlock cap on.

Other -family- stuff to take care of 1st...

The shed is a plain single stone one and with temperatures >freezing anything metal wet with condensation.

It could be fuel as the actual petcock was dirty/wet, as was the area below.

Shoved a bunch of white paper towel under the petcock and will check tomorrow.

The decals for both my girls came in today :-)

July 1986 the year my VF500F was built also the month/year I started with a certain company I am with still today (after 2 mergers and a split...).

Undecided on which color scheme would look best I simply made "3 generations"....

The nothing else matters will look good under the sidepanel VFR logo (methink) with the sane insanity apt for the VF... :goofy:

Dutchy, I´m afraid it looks like the front sprocket axle seal is leaking..... Can be the outer or the o-ring that sits betwen a collar (inside the sprocker) and the axle. Might be good whit just a clean and a now o-ring, worst case its a engine split to fix.

But look at the head valve covers if they have also been leaking, becorse of cold temps... the last pic of collector box looks like engine is wet all back part.

You know older laidies might have problems whit small uncontrolled leaks :wink:

The glistering wetness all over is condensation inside the garden shed, only redslut is parked in a heated garage....

If there is a break in the weather AND my work schedule, I will take puma out, remove the mufflers, front headers and collector box to give her a good clean underneath and hopefully trace "the source".

There was but still is a lot of grime underneath.

Having put a new rear shock in a sourced RT front fork emulators and springs, I'm not ready yet to consider letting her go.... In the few months I had her, put ~ 4,500km's on her, I like her a lot...

Known suspect for an oil leak is the clutch pushrod seal.. Unlike the VF750, 1000 and 1100, this seal originaly can only be replaced by pulling the engine.

Other option is to dremel the outer ridge of the engine case off and then pull the seal. Installing the seal back with an O ring will do. On mine I made an extra lip on the sprocket cover that prevents that same seal from running out of the engine case.

I have that seal in stock..

Other known leaks if it isn't oil based. Is the waterpump..

Cheers The Dutchy for offering light at the end of the tunnel :beer:

With the bike under "overgangsregeling oldtimers" I won't be riding her until March anyway.

Weekend forecast for rains and more rains so the "pull the exhaust and give the engine a good clean/inspection" will have to wait.

If you know another trick Bert, please do tell.

The Dutchy gave me a tip to pull the rod and put shrink tubing (the stuff you heat up) over the rod area where the seal would be. Tried that, but it kept leaking. So I put another bit of tubing on top and reassembled once more. But then the rain started. So I will try tomorrow if there is dry spell.

Made myself a nice gin and tonic and call it a day.

If you take a look at the pushrod and seal pictures posted by Dutchy, you can see a ridge holding the seal in place..

So the seal is placed from the inside of the engine.

On the VF750F/1000F and 1000R the final drive has a cover that can be removed to replace the oil seal from the inside.

The VF500 series don't have that cover. To replace the seal from the inside, you have to split the engine case.

Another option is to cut that ridge holding the seal away using a dremel. Than the seal can be pulled from the outside, and a new one can be installed using some RTV or other sealant to keep it in place. On my 500F I made an extension on the sprocket cover to keep that seal in place.

So far, so good. The engine ran for about ten minutes, pulled the clutch a few times. And no leakage.

Compare this with the earlier picture.IMAG3334-768x1358.jpgIMAG3326-768x1358.jpg
