What is the best bang for the buck pipe? Full system? Could you suggest one that offers a bit of power and a little less noise?

What about springs? Are they expensive? Hard to replace on your own? I'd love to get the suspension sprung for my weight, but the local shop wants way too much money. I was thinking of doing it myself. I see the rear shock as no problem to re-spring. What about the forks? Is it worth doing it myself or just dropping it off to the pros?

Tye, What kind of tires would you suggest as an all around off-road tire/mx? I'd like to specify exactly what I ride, but it's a mix of hard pack, rocks and sand. To try and pick a tire for one, would leave me lacking in other areas. I don't race, but when I do ride hard and hit jumps it's usually in soft dirt or sand.

Hope I didn't side track your thread too much Jtemple.
Alright...

Pipes - you're going to have to choose power or sound. Even with a FI bike, loudness means power. Its just the way of the mx world. BUT being FI you'll have an easier time having both. Try to find a pipe that has a dB killer included. ProCircuit, FMF, Yoshi and Leo should have them. I like Bills pipes also, but I noticed they only made stainless for my bike and I dont want to replace a factory OEM titanium system with a stainless one adding weight.

Suspension - I have someone do all the work on forks and shock. I dont understand the mechanics, all I understand is how soft or stiff it needs to be depending on the track conditions and jumps. I would DEFINETLY get it sprung for your weight, stock springs are for a broad range of weights and they try to get the valving to compensate for all they can. Ultimately I would see about getting it all re-done but springs are a good start. I LIKE my ProAction setup, but I would prefer a RaceTech or Enzo setup better. Anything to smooth out the chop on corner entry and exit is something I look for, but knowing how to set up suspension will be the bigger factor. See if you can find someone who can do springs and a setup, or if your mechnically inclined, just the setup. The more comfortable you are, the faster you can go safely. Going fast and getting all out of shape with your bike bouncing around isn't optimal.

Tires - easy, get a tire that suits whatever terrain will be hardest on them. I run Maxxis ITs, they're an Intermediate compound tire with a Hard terrain tread pattern. Most tracks here are soft deep prep but the jump faces are as hard as concrete. I use the throttle up until the lip of the jump which really eats the knob edges, and it seems to work ok. Granted I have a 250 but I use as much throttle as possible being a heavier rider. If you ride alot of loose rock areas vs hard pack rock, I would look for an intermediate tire with more of a paddle shape to the center tread. Dunlop MX51s have sort of that tread but I tend to rip the knobs off easier down here.
