The peace is over,Hydros clapping, who has tips??

Hello everyone

I'm really worried about my fat guy.
the problem is one or more hydros clapping with me and that not more than a few seconds but a very few kilometers.
Have already looked for remedy using oil flushing and change but that was without success.I have already read some things about searching here
was trotzdem nochma Fragen aufwirft.

So...
1. How can you get out whether the hydro is really or only the oil pressure holding valve (did that mean soo??)??
2.I know that you need special tools to build, what exactly do I need and can I help myself with other tools?
3.I would like to bring the front together, does this, if so, how best to do it??
4.Generally, I am grateful for all the tips this makes it as fast,inexpensive and easy as possible.

Thank you very much
Your weasel
