KX125/KDX200 Hybrid Build

[ChestonScout]

they are going thru a rough time and were trying to help.


They are both unemployed and looking for work. They have plenty of money stowed away but want to keep it stowed. Its been interesting. They do help out a TON. But I miss my house.




It does give me a good excuse for the wife when I want to go do stuff. hahaha

5 days. That's my limit for my inlaws, less for my own folks.

In fact, I believe that's why they invented the hide-a-bed sofa: "the appearance of hospitality with the lack thereof."
Nothing says, "go back to where you came from" like a metal bar directly under the middle of your back hidden by 2" of useless padding.

I decided I didn't like the two-tone green paint. So I shot it white and I love it. I'm pretty sure I"ll be powdercoating it white soon.

 

[GAR]

Nice, I like it.
Let me know when you want to modify the subframe, I'll bring my TIG over and help ya out.

 

[sixstringsteve]

I actually just elongated the holes on the subframe to get a little more droop there. If that didn't work, I'll swing by your place so we can tig it up. Thanks Grant.

 

[TJDukit]

I like the white, I think it will look much better than the green when the bike is back together.

If I were an engineer like Kurt, I'd make a Gaant chart. But I'm not. I think it'd take more time for me to build the Gaant chart than to build the bike.

Gaant's for the win. Just finished a massive Land Cruiser build here in Australia, much of which took place while I was back in Utah. All of which went super smooth with 10+ different vendors. I attribute the success to the Gaant chart

Though a list is a good start and more then many delve in with

Guitar lessons took most of the night, so I didn't get a ton done (plus I'm waiting on parts).

The suspension needle bearings were totally rusted solid. The linkage wasn't moving like it should. I can't afford to replace them at this time, so I just cleaned them out and greased them up. They're working great now.

I pulled the cylinder to find out if I had a weisco or stock piston. The stock KDX 220 piston is notorious for breaking and taking out the cylinder and the bottom end. So, just to be safe, I checked it.

I don't think it's a wiseco, or it would have numbers on it.


It's starting to look like a bike. I really dig the white.

 

[ricsrx]

Steve you are amazing! how do you get the motivation? that looks great!

 

[sixstringsteve]

Thanks rick. There ate few things that keep me motivated:

- add and the constant need to start new projects
- this build thread really helps keep me motivated
- great friends who hang out and help me wrench
- a deadline (trip planned)
- the faster you go, the closer the end is in sight. I can't stand projects that drag out over a long period of time.

 

[Rot Box]

Looks like the stock piston to me. Low hours from the looks of things Who's KTM? That looks like a fun bike.

 

[sixstringsteve]

Definitely low hours on the bike, which is why I paid as much as I did. It's getting tough to find a KDX that hasn't been abused. It'll be nice to have a clean platform to start with.

The KTM is 193 Kyle's. That thing is a ripper. Lots more power/top end than my bike, but that's ok, it'd be too much for me right now. I have a feeling I'm going to love this hybrid.

 

[sixstringsteve]

I got a ton done today. It's not as done as I'd like, but it should be rideable soon.

Installed:
- rear subframe & fender
- new top end
- rear brake
- airbox
- foot pegs
- radiators and radiator guards
- started on the electronics


I found out it's jetted with a 35 pilot and a 140 main. That's pretty lean for sea level, but it runs great here.



To-do before it'll run:
- modify gas tank so it'll fit around the upper water outlet
- finish wiring
- install carb and clutch/throttle cables
- work on the exhaust (I may have to lengthen it 1/2" at the head tube
- install chain
- fix front brakes (really spongy)
- top of all fluids

Then it'll be time to break the top end in. I think I'll be ready for a ride around noon on Saturday, but we'll see. It's coming together! I can't stress how much easier this build has been compared to the CR. Maybe it's because I've done this once before, but the KX is a lot easier to build around.


Note to self for future notice: the driver's side swingarm metal bushing is 1-2mm too wide.

 

[TROKITA]

i got a piston for a KDX if you need it

sure, NOW you tell me.


This bike shouldn't need a new piston for another 5-10 years. The stock 220 piston is a ticking time bomb, so I had it replaced asap, even though it had very little wear on it.

 

[sixstringsteve]

huge shout out to jentzschman, you're the man. Thanks for keeping me company and helping me with this build. It would have taken twice as long without your help. Now go get some sleep so we can break your bike in tomorrow.

Can't, building a shopping list to pick up at RMATV tomorrow... I can see the $$$ sign's flying out the window...

 

[sixstringsteve]

The goal is to have it running at lunch. It won't be fully assembled, but I plan to have it running so I can start breaking in the top end. It might actually be ready to ride tomorrow.

 

[rholbrook]

Steve, lean at sea level is leaner here. Don't burn a hole in the top of your new piston. Your better off running richer than leaner on a 2T
