I just bought an 06 crf 450r from a guy who had springs for a 220lb rider He installed the stiffer springs but didn't bother with a revalve. He gave me the stock springs (which have 0 hours on them) I weigh about 180lbs. I ride about 80% in the woods and the remaining 20% at the track. I havent played with my clickers yet. I want to make sure I have the right springs in there before I do. Any help would be great. Thanks  

I would go buy springs that are even softer than stock. What you need is a 0.42kg set of fork springs and a 5.2kg shock spring. The reason I say this is because the stock ones are 0.46kg for the forks and 5.5kg for the shock spring, so you are WAY off from your target area. Also, when you go to a softer spring you should consider a re valve(Moto-Pro is the best, he is VERY committed to giving you the best suspension possible, he has his valves and springs in 2 of my bikes and they ride like a dream) because you can over stress the shims causing a fatigued valving stack and that would rouin your suspension shims, then you will have to send it to someone who has new shims(which is a re-valve) and fix the problem. A lot of people say you don't need a revale, this may be true if your springs are stiffer or SLIGHTLY softer than stock. A revale is changing the flowrate of your suspension, allowing it to be altered to YOUR needs. If you are close to the stock area and you are not competitive, you probably don't need one, a re valve is only necessary if you are good, fast, aggressive, ride in rough terrain a lot, off the target weight, or want your bike to be 100%. If you have your suspension off, have it serviced and have them put in lighter weight oil(2.5w should work) so it will be a little more compliant for the trails.

That's my 2 cents.
