Advancer gives a noticeable boost to bottom end and makes cold starting a tad easier, trade off is a slight loss of top end but unless you spend the majority of the time caning the bike the benefits easily outway the costs. Having said that I wouldn't say that it's worth risking engine damage to fit and in this case it's probably best leaving well enough alone unless you take it to a shop to have it fitted and they assume all responsibility .........
