ESE's works engine tuner

[Niels Abildgaard]

The Garelli looks nice and it is a shame that twins were not allowed to compete against the 125 singles.
Two 50ccm cylinders could have ca 10% more blowdown time area than a single125 ccm but of course also 10% more combustion chamber area so ultimate power would have been more or less the same.(Aprilia 54 horsepower and two Kreidler27 horsepower?)
Engine and transmission of the twin lower mass than a single with balance shaft and much nicer two stroke sound.

I'm not sure where to introduce myself in this forum, which I've been following for a while. I own several classic motorcycles, including a 125cc Garelli twin-cylinder from 1985 that I've just finished restoring. I now want to disassemble the fork, but I don't know how. Perhaps Frits, who is on this forum, knows this type of fork and could help me.

Bonjour Bruno, I actually worked on that front fork myself. Back then we called it ‘White Power’, the original Dutch company name, but because certain groups started using the same name for racist activities, the name became tainted, so nowadays it’s called WP.
At the time, I focused on the hydraulic stop, which was designed to prevent metal-on-metal contact when the fork was fully compressed.
The problem was that the hydraulic stop worked in both directions: when fully compressed, it also impeded rebound. I remember milling a couple of slots, which solved the problem. But unfortunately now, forty years later, I no longer have any documentation regarding this fork or my modification.
