How did you end up valving them Wibb ?

Post by **Mr. Wibbens** » 01:59 am Feb 23 2011

Well the original owner removed 7 of the 32's

Everything else is pretty much stock except I removed the bleed stack and shimmed the 20x1.60 up about 1mm (it's sposed to allow the fork to sit and plant a bit better)

I also drilled the free piston

Midvalve is stock

Understandable why they removed so many 32's.
Those are some stiff bastages stock that's for sure.

I lucked out on the springs

I had .46's on my old forks and stock for the KX is .47's

I put new springs in the kx450 but would have to look to see what I put in it.
The stockers were to light

According to the calculater, On the 450 the stockers are ok for about a 170 lb rider

According to my sag numbers on the KDX they are perfect for me at 290

so, was it worth it? I expect you've been out without snow now...

They are pretty sweet

Where with the old forks I could expect to eat **** over the bars on certain types of terrain, now I just roll right over it like it's not even there

Looking back at it I think I was better off having problems

Now I know these twin chamber forks inside and out

so, how much was too cheap for these forks wibbs? (I'm trying to avoid the same mistake of buying a moneypit)

Post by **Mr. Wibbens** » 11:05 pm May 24 2011

100 bucks

heckler · Post by **heckler** » 11:31 pm May 24 2011

yeah, that's cheap. Thanks.

did you need a new capliper because of fit problems, or other reasons? I'm hoping I don't need a new caliper on an 06 KX450 fork.

Post by **Mr. Wibbens** » 05:13 pm May 25 2011

E series caliper is different from an H

Almost. 89-92 caliper is different. 93/94 use the same dual piston nissin caliper as the H bikes.

Well, I'm jumping into the game. 2006 KX450 front end on it's way. Apologies to whoever I sniped on ebay.

Got any recommended links for details on how to make this fork better for 270 lbs riding in the rooty, rocky forest? I'm hoping to do the work myself in the basement.

I know this one already, which is my starting point.

I found most of my info at Thumper Talk

Here's a interesting thing. I was out yesterday and the forks were kinda beating the hell outa me. So I went out 2 0r 3 clicks on the compression, thinking that would help it

This was the result

So I put them back to where they were, then 3 more clicks in

MUCH IMPROVED!

Bike tracked a lot better, and actually rode much smoother
