Well, Im gonna leave the seals on my new bearings alone BUT, if I wanted to add more grease, I'd just remove the inboard seal and pack the bearing. Grease flinging out inboard in the wheel hub will not endanger the brakes.

Sealed bearings are on my modern bikes and they work fine.

Andy, have you considered lightening your flywheel ? Escher really recommended that for mine.

I have, and will leave it along for the time being, with the logical thing being to modify another flywheel if I was going to, rather than the one I have :-)

Also, Huub. Please educate us more on your recommendations about oil pumps. Just using one of the new pumps offered by several sellers is not good enough? Need to get the pump for a twin?
depends what you are aiming for , lighter valves is a good idea if you dont want to end up with a hole in the piston, so that is recommended
lightening the flywheel also makes quite a difference, the gearchange improves a lot . whether you feel the gearchange needs to be improved is up to you.
i just got myself a stock cylinder when it had a holed piston ,
to be honest i cant see the point in tuning the absolute slowest bike in existance. but that might be me.

now the oil pump.
the stock pump has no bearings , the pump shaft runs in the alloy pump body. because of this it wears out at a amazing rate.
add to that that everybody fits a extra oil line to the cylinder head dumping oil on the inlet valve, oil that is obviously not reaching the bigend
especially when you like you NF to idle at 400 RPM.
the lack of oil seal on the end of the crankshaft doesnt help either.
and the camshaft is lubricated by oil coming from the pressure release valve , so leave the engine idling for too long with low oil pressure causes rapid camshaft wear.
i am not aware of somebody manufacturing falcone oil pumps with decent needle bearings, so i needed a upgraded pump


my solution is to fit a pump for a twin , which has the needle bearing , so no more problems with wear.
the original falcone pump has 11 mm wide gears , a pump from a tonti twin does better with 16 mm gears which adds 45% to the oil flow.
if you get a upgraded pump with 18 mm wide gears , you've got 65 % more oil flow.
running that pump the oilpressure release valve is open all the time...

if you buy a new one, the upgraded pump is cheaper , so that is a easy choice.
if you are on a tight budget , get a used pump from ebay, and modify that.
even a used pump from a T3 will be far better than a new falcone pump.

cheers,
Hubert

Hubert, give us a link to one of the upgraded pumps, please.

Also, didn't you once say that the mounting holes need to be widened for the pump to fit the Falcone?

i use aftermarket pumps with 4 mm wider gears ( 16 mm instead of 12 mm wide , resulting in 30% more capacity
the t3 pump has a proper needle bearing , due to the lack of bearing the falcone pump tends to wear out early.

as you can see on the pic the mounting holes on the falcone pump on the right are smaller than the T3 pump on the left
i made a plugs to press into the t3 pump mounting holes, and redrilled the holes, using the falcone pump as a guide.

the other difference is the end of the oil pump shaft,
on the falcone pump it is a taper , on the T3 pump a straight shaft



i weld up the hole in the falcone gear , and turn up a nice straight hole in the lathe, if you dont want to weld your precious gear you might get away with using a tapered bush.
i enjoy using the lathe....

Here's your previous post and also this link that you gave -

http://www.ebay.de/itm/MOTO-GUZZI-Ol...-/160865867818


But, what about the pump with 18MM gears ? Where is that?

the one from the link has hohere forderleistung , wich means improved capacity.

it is the one with the 18 mm gears

Just had e mail from Barbara Escher, the parts have been ordered (lighter valves and a 94mm BMW piston) the engineering work will be done next week. So looking forward to getting my NF back on the road.

If anybody needs help contacting the owner or translating, drop me a mail.
I'm not close (200km) so I'm not gonna look it over for you. Maybe some other Duthman living closer will drop in and offer that service

Hopefully not the result, of some reality program's big suprise build mod,
on an unsuspecting Falcone owners dusty resto candidate.

Good one bk brkr baker !

Question

Pronounced fal cone, or fal coney?
Just found this - watch it scoot backwards when he "revs" it.
