Ah, now that you say it... It's always easier to read, than to write ;)
I'm from Germany by the way. :)

Your English is good, I can't speak a word of German. Nice to meet you. The international aspect of this forum is almost as fun as the motorcycles.

Thanks,it's getting better little by little. It's easier to learn today, with a lot of shows, movies, videos, books etc. available through the internet, and multi-language DVDs... and forums! 8)
Only one catch: I tend to mix up British and American English quite a bit ;D

A partial clue is in the spell-checker, you will find wiggly red lines appearing under British English spellings on forums (fora?) using American software. "Divided by a common language" as an Irishman once wrote...

Mudguard/Fender*

Gudgeon pin/Wrist pin

Tyre/Tire

Gearbox sprocket/Counter-shaft sprocket

Colour/Color, etc...

* I sincerely hope that there is some automotive component somewhere, maybe the mythical warble-flange bracket, for which the American English is "Gibson", in the interest of fairness, of course.

As said: Try some heat to the barrels, light force from the top of the pistons and a lot of soaking with creep oil.

Not familiar with creep oil but PB Blaster is the best penetrating oil I've found.

Is the head off? If so, a pic of the bores will reveal just how rotten/seized the problem is.

No,not free yet.But sea foam deep creep and heat finally moved them.Dumb question,how far can i pound these lovingly til i reach the bottom of the stoke?I do not want to pound at the bottom of the stroke.They are not moving easily.

About the same hight as there are fins on the barrels. The Pistons move into the case even further, but I wouldn't risk it. Once you are down there, you should be able to pull the barrels as far as the pistons have moved, put some piece of wood beneath them and continue on the pistons.

What I did once (with a single), was to make a sturdy (5 mm or more) steel plate that fits over the studs, put wooden block between the plate and the pistons, an tighten down, bit by bit (don't exagerate: time and patience are half the work).
