Just bought my 1st real mower, Z 60 had it for a few weeks and decided to put some flex forks on it, ride quality improved but the question I have is while driving full throttle up my lane or even in the grass the whole fork has a wobble, both sides do it. Wasn't an issue with the old set up. Best way to describe it is a good old tank slap for those familiar riding a bike 
Thanks in advance.
