Changing my stock spring with a heavier one...I weigh 225lbs :cry: . Went to Race Tech put in appropriate info said I should use a 5.6 kg spring. Took off rear shock, stuck trying to take off origional spring! How is is done :cry: ? There is a large gold colored nut on the dampinging rod leading into bottom part that holds the bearing/bolt hole that connects to swing arm. Please let me know how to remove spring! Info much apperciated :cry:

Undo the 2 sag adjustment rings (the upper one is the locknut) all the way up. The spring then comes loose. There is a collar at the bottom of the shock spring which has a slot in it. Slide that out and the spring base plate. Spring will then slide off the bottom. :cry:

some of us are not so sure the race tech numbers are correct. they seem to be on the light side. at 225, you need a 5.8.

Where can you go to get the correct spring numbers? I weigh 220 and although I am just breaking in the suspension, I would like to re-spring before the serious riding season starts.

More like 6.0-6.2. You are NOT going to get correct sag numbers with anything less :cry:

Post this question in the Suspension forum (or do a search - it's been answered may times before) and you should have an answer from one of the Suspension tuners who hang out there.

I agree on the numbers. I weigh 200, and have a 5.6 (Ti). It is a huge improvement over stock, but if I had it to do over, I would get at least a 5.8.

It's easiest if you loosen the spring collars with the shock still mounted in the bike, then pull it out, remove them completely and swap the spring.

Strange! I weigh in at 210 and I fitted a 5.6 and the sag sets up just fine. The numbers cant be wrong so maybe its just the differences in individual springs? :cry:
