i have a problem my presureregulator is dead and i cant get new one duc not produse anymore i got 1 from a 900ss but its feel as the bike loos power any idea what i doo?

Get one from a scrapped 907? Having played around with an adjustable fuel pressure reg on my racing 996, I don't think your lack of power is down to the fp reg. It only makes a difference at (very) high revs. I would check to see what pressure you are actually getting (I have a gauge you can borrow if you're in the UK) or put the bike on a dyno to look at mixture throughout the rev range.
