Thanks for the useful information it helped a lot.
The risers are fitted this way because the former owner was about 6' 5". Maybe it was more comfy for him this way. I like this setup, too.
There are some things to fix on the bike, for example some oil leakage on the alternator side, clutch is slipping - must put in some washers and change the plates, HD Sportster muff should be installed because this turn-out is a "killer" and some electric problems (strator must be repaired, I have only 13 volts because of a short circuit down there).
I hope it will be in perfect condition soon, its just the question of money.

Thanks again!
PS: I'm sorry, Lancer. I don't know what the problem could be. I have been using this webspace for a year and never met this kind of bugs. Apologies.
