2007 CRF450X fork questions.

[jrlastofthebreed]

I am new to the snowbike world and just bought a 2007 CRF 450X and a 17 Timbersled ST.
I see a lot of people posting about needing to stiffen the front forks either by adding new springs or adding air pressure. For instance Airpro has a neat set up for about $130.
My question is this. Is there any reason i shouldn't just take out the bleeder valve and install a schrader valve? and how much air can i add before i start blowing seals. Will this fix the bottoming out issue? I would appreciate any input on this.

i have an 07 crf. dont rec.adding air as you will eventually start those fork seals leaking.Original bleed screws were there to let excess air out after a ride.
you can try raising fork to max level and turning compression damping adj.all the way in but these are only patches.

I just ordered .56kg springs from Cannon racecraft.after 2 seasons of patches lol

We actually haven't had any issues with blowing fork seals. That was our first concern when we thought of this idea, and a valid concern. And on dirt, you do want to let air out of the bleeders. Makes for a very harsh ride if you don't. Believe it or not, the seals for the outer chamber on a spring fork are a standard seal. Same ones used in an air fork. The Showa TAC fork, (fork with 3 air chambers in the right fork and spring on the left) has a standard outer chamber PSI setting of 16.7, with adjustment up to 20psi. So we don't expect any issues with blowing fork seals directly related to our bottoming kit.

thats great to hear that.Glad you guys have come up with a viable alternative.
