I'm thinking up using a lower wt fork oil up front to help the bike take the square edged rocks we have around here. Has anyone done this vs the obvious valve job at a suspension specialist. I'm thinking of doing this before the more $$$ revalve. The bike seems to be sprung pretty good atleast for my 190 lbs geared up body. I launched it a few times a couple days ago and even with a few nose heavy landings it didn't use all the travel ever. Thanks for the input. Cody
Had the same problem as you. The stock 0.511 KG/mm front springs are a little heavy for a 190 lb rider and the compression damping is much too stiff. I wanted to have the forks revalved but the shipping costs were out to lunch. Settled on a set of 0.46 KG/mm front springs and the adjustable compression dampers from the pre 08 TE 610's. Also changed the rear spring from 6.4 KG/mm to a 5.4. Race sag is spot on for me (190lb) with this spring. These suspension changes made a vast improvement to the 630!
The adjustable dampers would be a good start instead of just going with the lighter oil. Pre08 TE610 huh?? thanks Willie.
The lighter weight fork oil doesn't help much with the high-speed compression damping. I tried 5W and the biggest difference was that I was blowing through full travel way too much. Not a huge difference on the trail chop. I'm 220 no gear.
Tell me more about the comp damper adjusters. Is it as easy as pulling out the plug and threading those in? Any internal work needed? I am about to drain the oil and pour in some heavier oil (probably 15) hoping to fix the dive issues I have on throttle transitions, but this is definitely a better solution.
No internal work required. When you remove the bottom plug the compression shim stack fastened to the plug will have to be transfered to the adjustable units.
