Hey guys and thanks for having me, as I just joined up. So Ive had many yz 250's over the years, but this is my first kdx and Im definitely happy with it, just not familiar with what type of mods helps it the most?!? Got a fatty FMF on it, should I change to a gnarly or leave it? New twinair filter. Powercore II silencer. Thinking of adding Boyesen reeds. Flywheel weight possibly? Thanks in advance for the input.

Personally, I would leave the current pipe and flywheel. Focus on nailing down the jetting. Might switch to dual-stage reeds for a little broader power.

But almost all the biggest gains speed-wise after that are in the chassis, especially the forks.

Thanks so much and please excuse my ignorance....dual power reeds? Boyesen reeds? Change reed valve and reeds?!/ Thanks and look forward to hearing from you.

i have vforce 3 reeds in my 04 kdx 200

Thanks guys...and what about those chassis improvements? Stiffer fork springs maybe? Its pretty soft but Im also 230lbs, intermediate rider.

I have a rad valve on my kdx i had the boyesen pro reeds b4 that and the rad valve was an even bigger improvement

Guys Fredette racing is showing a replacement fork springs at .40 kg, and replacement shock spring 5.2 kg for rear. Definitely running soft here but again love this bike (97 KDX 200) . Any experience or recommendations appreciated. Yall have been helpful and thanks. Glad to be here. Geoff

What is your weight in full riding gear, including water backpack, extra tools, etc.?

check it tomorrow and get back to you....thanks so much for the assistance. Should be around 255 lbs but will make sure and post. Again thanks...

Yep. 248lbs with all gear on. Intermediate trails rider/occasional hare scramble race. Thanks Again. Geoff

.40 springs will probably be to light for you.
