I've offered to assist my riding buddy Gary with the restoration of his brother-in-law's 1981 XS1100SF which has been sitting for a number of years. He's got the Clymer manual , and he's now got my related knowledge of the XS650. He's asked me for a referral as to the best forums on the XS1100, so I'm asking for your knowledge/experience base of the most informative and responsive ones. Thanks ahead of time. . .
