I went +4 and it's still a great bike for duning. Like Wicked said get your shock rebiult or at least get a heavier spring. I rode with the stock and it SUCKED! MattSCEC has my rear shock right now and I'm sure it will be great come New Years, he's already done a pair of front Elkas for me and I couldn't be happier. Hit him up he's got great pricing and quick turn around
