The springs are for the power valve. Your bike should have a yellow spring in it.

Those look like the same parts that I got with my '06' 250sx.
What year is your bike?
54837072000-auxiliary spring 'soft' red
54637072300-auxiliary spring 'mid.' yellow
54837072100-auxiliary spring 'hard' green

My bike came with those parts in that bag that the manuals and stuff are in.
I also got a box of stuff with my bike. It had a spare set of shrouds, front # plate, grips, air filter, # plate backgrounds and shroud graphics and a pad for the tripple clamps.

Red, thats is why it is painted red. Be prepared for a different animal. Yellow or green for less of a hit in muddy or slippery conditions. I use yellow at all times. Two much hit in the red for me.

Of course you never need to re jet for a different power valve spring so you must have had other jetting issues.. I would have run the same spring, then ride the bike for a while, then change springs.But of course you can still do that. Lets us know what you think of the red monster.
