Did you pull it straight out...did it put up a fight? Curious, I'm getting ready to go through that myself. Micah

Sweet build! What's the story on the gas tank boss extraction? I'm interested in what you did there. Micah

These are the only two pics I have of my old 1989 Kx125 (circa 2007). It was pretty much stock. Paid $700 for it with a shot water pump. Rebuilt that and rode it trouble free except for the fact that one of the subport power valves ... more »

I did not take off the fork lugs. I would think that they unthread...with the use of heat. As for the shock reservoir, it unthreads. If you go to my youtube channel I did a video showing the tool i made from an angle grinder spanner wrench. Micah

Thanks for that tip. I dont know how the Chinese spring can cause the slide to get stuck though. The cap needs to compress the spring before it can even be threaded. Also, have you noticed inaccuracies between the same size jets chinese vs keihin?

They are drilled "black tape covering them." The drilling profile looks very nice too.

Very little progress

I really did consider swapping the front end. Or at least upgrading to a newer generation of the 4054's, which offer better parts and performance. Hell, these first gen's don't even have compression or rebound adjustments. But, I thought the bike would ... more »

Almost a month later, still no fork parts. Just got notice that they should be shipped this week. The inner and outer bushings are discontinued. The "inner" bushing for lack of a better word is very specialized. It is the part that you see in the cover

A quick and dirty test showed correct ohm range for one of the stator poles - the other flashes numbers and then goes dead (to number 1). I'm guessing that's the problem, but not sure. After finding the crank wobble, I have now decided on a full engine

Got caught in a lull. Finally found time to pull the forks and tear em down. I had no clue how these came apart but there are no compression or rebound adjustments in these simple WP 4054 old school 40mm inverted forks so they werent too hard to navigate

Good point

Bringing this back from the dead. I have also been using ERT2 chains and recently ERT3. I agree with langhammx....this thing stretches way too much and the gold looks like poo in no time. Im done, but not sure what to switch to. I love the low drag of ... more »

Shifter done. Welds look ok, but both the old shifter and the wrench were chrome plated and as usual I couldn't be bothered to really clean the metal up. The fit is really good. And while it looks long, remember that the old shifter was pretty stubby.

I messed with the shifter. Here is how it was before I touched it. A prior owner tack welded the pivot into a fixed position and did the grinding on the weld. I was able to remove the weld and clean it up to make a functional pivot again.

And ... more »

Thanks to Husabutt on YouTube for pointing out that one of my rear frame rails appeared to be bent. After some measuring I comfirmed that he was right. The silencer side was 1/2 inch higher, which is why my fender was twisted after I mounted it. I should

Thanks Matt...there were a couple good shots in there. My clutch cable I decided to leave alone. It has one lone broken strand up by the perch. Certainly I can use it for now and just keep an eye on it. The throttle cable was fubar though and already ... more »
