I just bought an 2003 EC 200. I love this bike, it's perfect for the tight eastern woods here in Florida. We also have alot of sand and whoops in some of the trail systems around here. Does anybody have any recommendations on suspension set up. I used to ride a DRZ 400, so I like plush set ups. This EC 200 has front and rear Ohlins suspension, I've never worked with these shocks before. It's currently set out 15 clicks on front forks, the rear is soft it tends to hop side to side in the whoop sections. Any ideas ? My weight is around 190 lbs with gear on. Should I tighten the rear spring?

Thanks
