Hi, While adjusting the chain I noticed a fair amount of backlash when in gear,I can probably move the rear wheel 2 to 3 inches back and forth,is this the norm?the bike rides o.k.with a bit of snatch between 1st and 2nd sometimes 2nd and 3rd but nothing you'd think was wrong.Bike is a 2010 FZ1N non ABS. Thanks.
