I owned a 03 RX-1 last season I did not like the suspension but loved the 4 stroke power. I sold this machine and purchased a 07 Apex GT with 1800 miles on it. I rode it for the first time yesterday and the trails were rough as I was trying to keep up with my son on a 07 600IQ I felt like I was riding a bucking bronco. I swaped with him and he made the same comment. I hope with some set up I can improve this. May be I choose the wrong machine. I felt I did my home work but not sure. I read a lot of post about valving the rear shock is this a must? Is there any adjustments that can be made with out the revaleving the shock? I weigh 190lbs do I need to change springs to stop the bottoming out? could the shock just be bad? The unit still has warranty would taking it in do any good or is bottoming out common with a stock machine? Thanks
