125-200cc WR125 Teardown in 8 seconds flat, (Caution: Bike Porn)

Time to quote myself.....
I pulled the PWK 38 from my Yamaha and did some comparing.

PWK 36 (1999 kx125)
small end ID to ID 37.7mm
Big end ID to ID 52mm
Lip to lip (length) 75.8mm

PWK 38 (2006 yz250)
small end ID to ID 38mm
Big end ID to ID 54mm
Lip to lip (length) 75.8mm

Small differences, but different none the less.
Length on both was identical, so I guess my yamaha carb is a shorty too!?!?

Jake, we've never really ridden the trails together... I've been on a couple "bigger" trail rides with you, but looking forward to getting out on the trails with you... Hurry UP

I was talking to Kelly, and I know he can speak for himself, but he seemed interested as well... Let's look at next week maybe?

Thank you for posting the description of the shock rebuild.

A question: what sort of oil did you use, and how did it work for you? I want to try revalving mine and would like to avoid doing a bunch of rebuilds to get the oil viscosity right. BTDT with another bike, that was enough.

It was 5wt, I think Bel-Ray.... It seems to work great now that I put the spacers in the swing-arm correctly. There didn't seem to be anything wrong with the shock before servicing, just wanted to freshen it up.

Livin in the Beav eh??? What do you ride?

Update:

About 30 hours on the bike since this mod, and they are holding up great!!

Thanks.
I just bought an '11 TE250, mostly ride in Diamond Mill/Jordan Creek. I put the fat boy springs in it and the back either has no traction or kicks depending on where the clicker is set.

6.0 Yeah, just a bit. I found a bit of a surprise in the shock, I'll start a separate thread for that in a bit.

ive got a stock wr300 shock spring in my garage. i think its a 5.4.
Feel free to try it out.

And the shock is easy to work on. much easier than a kyb or showa imo.

Thanks, but the 6.0 gets the sag numbers just right. The 5.2 (I think that was the stock rate) was way off for me. And you're right, it was really easy to work on.

I started a thread about shocks over here:
