I know this is an old post but I did want to follow up on the last post about TCS. I heard a lot of great things about this company so I sent my brother-in-law to them to get his 450r shock revalved. The first try ended up being so stiff that I told him not to ride it hard through the whoops or he would get hurt. He did what any normal male would do and ride it through the whoops; surprise, he crashed and cracked some ribs.
Sent it back and got a slightly softer setup but still way too stiff. The rear suspension never went past half way (we annalyzed it on video).
Sent it back and got a slightly softer setup than the second time but I feel it is still too stiff.
He is deciding on sending it back a 4th time. TCS customer service is great and there is no charge on the 2nd, 3rd, and possibly 4th time.
It does make you wonder if they know what they are doing or if they are just "throwing darts".
