I have just purchased a 954. Have ridden it about 500 miles. I've been away from riding for a few years but the bike seems to be very light in the front and 'shakes' under acceleration on bumpy roads. I've read many of the suspension related articles and it appears that everyone is suggesting rebuilding of both front and rear suspension or upgrading to aftermarket. Looking for advice as to where to start on this effort. I've tried modifying dampening, rebound and preload but haven't been able to find a great setup as of yet. Any suggestions/advice is greatly appreciated!
