Default Suspension too soft?

     

I have a 93 cr125. I am 16, 5'9, 130lbs. I do mostly the track getting at the most 25' of air. I do some trail riding too. Right now I have the forks and rear shock as stiff as possible. 145psi in rear. When I land a high jump on flat like a table, my suspension feels bouncy and not smooth, kinda like it wants to throw me off, and is pretty scary sometimes. I try landing a little on the back, and it feels too soft. I rebuilt the front forks last year. Should I put more oil in them? Am I landing wrong? What about the back?(oil level is right) has a blue spring. I just think something ain't right. Also I get cramps pretty fast the first 30-45 min of riding so I stop fer a minute or two. Eventually they go away. What causes this? Is it normal? Am I not realaxing enough, because with the suspension like that I feel kinda nervous for a while.

Have your forks and shocks been serviced recently??
Do you have the correct spring rates??
Have you set the sag??
How are the linkages in the rear??
Have you set your clickers ( front and rear/rebound and compression ) to the manual spec??

The springs are stock, and its worse when the clickers are stock. The linkage is fine and has new bearings. How do u set the sag?

are you adjusting the compression or rebound?

The too much rebound will make the bike feel bouncy. Happened to me this weekend, was getting headshake off flat landing because the forks were rebounding too fast. Turned the rebound a few clicks towards Hard in order to slow it down. Problem solved.

Keep in mine suspension should be serviced every season. Nobody seems to do it until it's clapped out. On the shock are you adjusting high or low speed compression? Have you played with rebound?

I would start by getting the correct spring rate for your weight, front and rear, then set you your sag, ( asumming your front and rear are serviced properly........ ) set your clickers to stock, see how you go.

You'll almost always chase your tail if you don't do things right, start from the basic stuff like spring rates etc finally getting to stock clickers settings. Now if you feel like the rear is bucking you off then your rear shock may need an oil change and general service. How well did you do you fork service? Did you measure the oil exactly? These are all very important things to remember, suspension tuning is not just an 'every mans job' so if you wana do the best you can do without a suspension gurru then I'd suggest you start with what I'd suggested to start with first

If the stock springs are in it they should be close for his weight if my memory is correct.

Should be right only mentioning start at the spring rate as its the basis of correct suspension tuning ( which I'm sure you'll know ). Hopefully the forks are functioning correctly after the 'service' performed as stated.

You said it best "suspension tuning is not just an 'every mans job' . Been doing it for 10 years and am still learning.

Same question, I got a CR125 2004 frame 2001-2 engine and I think the last owner said that my cr's springs are for 90kg man and am only 55kg should I be adjusting something..? I don't feel anything going wrong at the moment
