I am a 175 lb. intermediate rider. I have an '06 YZ450F and ride almost exclusively on trails (from desert to tight and technical single track). I've always preferred the firmer suspensions and lighter weight of race bikes and have usually opted for race bikes (2 and 4 stroke) over WRs and modified them for the trail. I have been very impressed with the stock suspension on the '06 and have been able to dial it in to my liking and riding ability. With the hours on my bike, it's past time to change the oil/seals etc. in my forks, and I have been wondering whether it would be worth it to have the suspension revalved and set up for my weight/riding style while I'm at it. I've heard that the stock suspension is pretty much dialed in for my weight, and I'm not sure spending the extra cash would result in a suspension mod that I would notice much or that would improve my riding (and no... I'm not trading off this mod to buy an aftermarket pipe). Should I seriously consider a full suspension upgrade/revalve... or just stick with a simple oil/seal change and hit the trail. Thoughts???
