it might put more stress on that side of the fork, if it feels that good y not just buy some softer springs?

Dude's under a hundred pounds, too much stress will never be an issue. One yellow spring should do just fine,

Dont know what the softest spring colur is but removing one spring i personaly dont recomend it. I agree that it has been done in the past but in this case if your agressive doing big drops 100 lbs does make a differance. My son is 100.1lbs with a Marzocci FR150 fork set up stock & can bottom it on a 8 foot drop. I would talk to a motorcycle suspenssion person for a better setup if the manufacture can not help. The internals can be modifyed to respond better for your weight.

shook_dh - One yellow spring should be perfect for your weight.

dogonfr - If your 100lb son is bottoming, then you have an incorrectly setup fork for his riding. Moto shops can't magically modify internals for different weight. What you can do to dial that fork in is to raise the oil height to help resist bottoming.

lets see 100 pounds is very light

what happens if that one spring fails???no back up...is it worth it even at 100 pounds

if 1 spring fails i have the other spring... i dont do that big of drops and its gona be temporary till i could save up for softer springs. if it starts bottoming on drops i wont do them or try to be smoother. when i was riding the dhi it the shock it felt that it had no dampning at all so it bottomd on the smallest drops so i thing that tought me to be smooth. so ill try to leave it with one spring see how it works out. which side si it better to take out from rebound or dampning?

If your suspension isn't bottoming once in a while it's setup incorrectly.

You want to be using your travel, otherwise what the hell's the point in having it? And off an 8ft drop I'd say it's perfectly fine to bottom considering we don't know the details of the tranny or anything of that matter.

As for the original topic, have you thought about putting a lighter weight oil into the fork first and messing with the adjustments before taking a spring out? That's what I would try first if I were you...

well i took out the preload spacers, as i was reading the online manual for it messed with the rebound slow compression dampning. i dont think thers anything i could do with those two springs when they are for a 150-180 lb rider other then taking one out

Do the oil.

im not getting full travel... not even half travel on really rough stuff. i dont think thinner oil would help that much and the springs are for 150-180 riders i dont think oil could change that

Running a fork with one spring is fine. Don';t make me list the hundreds of forks that use one spring. Just a couple:

Boxxer ride - its a boxxer, uses one spring, so WTF?
Fox 40
Fox36
Pike
Every coil Fox ever made

And how the hell is a coil going to fail? It's not going to fall out. It's not going to scrunch down and stay compressed. So WTF?

Dude, you're fine. Have fun riding your fork. If you bottom it too hard in the future, just add a stiffer spring and dual soft springs.

how about wearing a 50lb diving belt then two will be just fine

SMT has a point that hinting that if you are going big with that fork, having a pair of springs to "assist" each other in the event of failure is much more comforting then a complete failure of the one and only.

Please explain how a spring "fails"...

If your spring falls out of the fork, then having a spring on the other side is the least of your problems. Otherwise, coils don't just "fail".

You have never seen fatigue cracks which lead to eventual failure of a coil spring? You have not lived I am afraid.......

That's only unsafe for a rear shock where the spring could come competely off.

A fork is different. Even if it cracks and splits in one,two or even three spots at once the fork is not going to compress much more. You will have pieces rattling around, but the fork will not be a safety hazard by any means as long asit isn't ridden hard after coil failure. It may compress 10-30mm, but not give out completely.

Spring failure is only unsafe in air springs, where the fork completely colapses.

Once again, we're talking about a 100lb kid here.
