I have a '03 150F and been jumping it alot lately. My problem is that i bottom out the suspension every time. I was wondering if there was a way to make the front forks stiffer, any tips would be appreciated...

Go with a heavier spring kit.

BBR springs took care of our problem with this with our 03. But the rebound is considerably more. They work great for me jumping and great for my father, but just too much rebound for my skinny bottom when riding on a track.

if you want to stiffer up the first few inches of travel add some preload, if you just want to stiffen up the last few inches of travel add more oil, if you want it all the way through add thicker oil, or a more effective alternative to the thicker oil is stiffer springs
