The Fleet

I also cleaned up some wiring. The previous owner had started the dual sport kit, but just left the bulb socket and a bunch of wire on the bike. Last trip it was falling out and dangling. So that’s all gone.

Suspension done.

On the list.

Four Stroke Works Header
Valve adjust
Port and Polish head
Star Wheel shifter mod
Retime ACR for easier start
Water pump guard
Front brake line guard
Radiator braces
Pumper carb
replace idler gear. (this is a known week part of the KLX so I'll just replace it)

I’ve been remiss on some updates. All the guards and braces are on except the MSR rad guards. They are on backorder.

Here are some pics.

Water pump guard



Got started today. Got it torn down. The head goes to the shop tomorrow for a port and polish, and new valve seals and guides. On a surprise note when I tore it down I realized that it was not a stock so did a bunch of research and found it has a thumperracing.com 340 big bore kit. Which is awesome because I was going to spend the money and go big bore next winter. Don’t need to now.

The pumper carb is a 37mm Keihin. Its borderline too big. The jetting will be a challenge.


It will take some custom fitting. Also I have a fourstrokeworks header. Here it is next to the stocker.

I’ve also had the rear shock rebuilt by a local racetech trained tech. It really needed it.

So here she sits waiting for a good cleaning and reassembly.

So a known issue with these is play in the idler gear then they hit the spur gear and crack the case. The bushing wears out. So I put a new idler on.

Play in the idler gear.

New one in and ready to go.


Also they will pop out of gear occasionally. Four stroke works makes a new star shift gear for this.

Old on top new on the bottom. Also comes with an aluminum spacer for more spring tension.

Got the carb in. Had to grind down the intake and put a grove in it with a file. Also had to cut out half of the top motor support. I’ll be fixing how it looks once its running and moving.

It is a really tight fit.

I took it to my who does all our carb tuning. I should have it back in a week or so. He lives 2 hours away and is coming up next weekend so hoping he has it with him.

[hadfield4wd]

Well carb tuning seems to be going well. Fitment is tight and I’ll have to work on some bracing in there.

Started up second kick with the carb tuning based on internet research. Pretty happy. You can see in these pictures this carb sits high. Looking back I’m sure there would have been a better FCR37 to put in this but oh well this is what I have so I’ll make it work. You can see where the push cable from the throttle hits the tank and doesn’t allow it to sit down all the way.



Here you can see the nasty angle of the push as well. Throttle was not smooth at all.



So we’re going pull cable only. Here’s what it looks like with the push cut off. He still protected the cam on it.



Also the cable then didn’t work right so we went with a KX500 throttle and a custom cable. The cable is being made by motion pro and should be ready in a couple of weeks. Once we’re sure it works I’ll order a spare.

While I was at it I ordered a new clutch cable and a MSR Pro-raptor clutch lever assembly with the hot start lever. I needed the hot start lever and I like the adjustable clutch force on this. Should make the clutch super easy. Although we had a bit of an issue. The hot start lever hits my horn button. So for now Chuck is just getting the bike running and when it gets back to my house I’ll fix that. I have some ideas in my head on how to do it, I just need to see it to see if they’ll work.





So basically we’re waiting for the throttle cable and we’re done.

[hadfield4wd]

Well the cable showed up Thursday. They really has us bend over though. $75 when their website says $35. Chucks been tuning the carb. Has a little to do in the midrange. Changing a jet and moving the slide one more spot. The ap shot is awesome he said. Will do power wheelies in 3rd gear!! Too speed is about 65. I may regear for a little more, but I don't want to lose top much in the bottom.

Got my new chain a sprockets on. Cruising speed is now 55. It'll go 75ish but that's not a god idea in a dry bike with unbalanced tires. I did actually get the front balanced as it was so bad. Also had to rebuild the forks. Picked up a spare rear rim to mount my other tire so based in conditions. Mud tire and dry (trials) tire. In addition I picked up a new frame with a clean title so I can register this properly as well as make some modifications. The sub frame which holds the seat, rear fender and airbox is welded on. A lot of bikes have a remove able subframe to get the carb easier. I will make this one removable. And also fix some known weak spots. And finally I have some better forks on the way. I will get more adjustment. My current forks have compression adjustments only and rebound is adjusted by oil weight. My new forks will have both compression and rebound adjustments. They will need a total rebuild and new front rim so it'll be a while yet for this.

[hadfield4wd]

So an update. I’ve got about 300 miles on it.

This thing is great.

Still some little things to iron out.

Lets talk tuning of the FCR37.

170 main jet
Needle 3rd clip from the bottom
45 pilot jet
2 turns out on the fuel screw
40 leak jet
No oring yet but I might do it still. I’m undecided. There really is very little bog if any.

This is hands down a great mod. I know I did a bunch of performance stuff all at the same time, so it’s hard to determine what did the most but this bike really is fast.

The hot start works great. Never had a bike with a hot start. Makes starting easy.

Got the front tire balanced as it was so bad. Also had to rebuild the forks due to a leaky seal. I used 7.5w 95mm from the top. I have some better forks on the way. I will get more adjustment. My current forks have compression adjustments only and rebound is adjusted by oil weight. My new forks will have both compression and rebound adjustments. They will need a total rebuild and new front rim so it'll be a while yet for this. Probably this fall.

Picked up a spare rear rim to mount my other tire so based in conditions. Mud tire and dry (trials) tire. Probably get that mounted up tonight.



In addition I picked up a new frame with a clean title so I can register this properly as well as make some modifications. The sub frame which holds the seat, rear fender and airbox is welded on. A lot of bikes have a remove able subframe to get the carb easier. I will make this one removable. And also fix some known weak spots.

I put the bike on a shipping scale to see how much it weighed. I was hoping for 263ish. This is full of fuel. I just filled it up before I got there.





The issues I’m working on.

The hot start lever hits the horn button. Plus the kill switch on this switch pack is broken.



I am working on new switches at the moment. Looks like I could get away with 4 switches on the left side. (left turn, right turn, kill, horn) Then move the head light and hi/lo beam switch to the right.

This would be ideal. However I’m trying to find a solution like that and the guys at highwaydirtbikes.com have been working with me. The easy solution is to get rid of the turn signals, which I may do, not sure yet. They have some cool switches and have been helpful.

The second issue is my mirrors suck. I can only see my shoulder. They don’t stick out enough. And they are cluttering up my bars. With the mounts for the mirrors there I don’t have full adjustment of my levers. So I’ll be doing some sort of custom deal here.

Also I have a dyno appointment for 5/29. 1 to get hp and tq numbers and 2 to make sure the A/F ratios are good.

Then get to work on my frame and forks.

[hadfield4wd]

Mirrors fixed. Before I hit the dirt I can just take them off with the thumb screw and put them in my backpack or truck.

After





Took off my turn signals. Apparently I broke one of the back one riding again. So instead of just replacing them I ditched them. I ordered a couple of really nice switches from http://www.highwaydirtbikes.com they look really nice. So I’ll have a kill switch and horn on the left hand and the lights on/off and high beam on/off on the right hand. This will allow me to use the hot start. I also ordered a key switch as anybody can just get on my bike and kick it and go.

I cleaned up the wiring to the back of the bike when I took off the signals. I’ll clean up the front with the new switches I’m putting on.

Before



After



Finally I got my DOT trials tire mounted on my spare rim. That rim also needed a new sprocket to match and new wheel bearings. Its 2” larger than the mud tire. That will make a significant difference in RPM’s. I haven’t had a chance to ride it yet as when I get home from work it’s raining. I am happy to have the extra rim. If I get a flat riding at HMT or any place other than street riding I can just swap and go. Easy and fast.

Anyway here are the pics.

[hadfield4wd]

Ok so I got my switches all wired up, heat shrunk and in loom. Pretty happy with the result. Also made a quick bracket for my keyswitch. I ditched the turn signals. Here are the pictures.

Before.





After

Kill switch is Red, horn is black



Red is Low Beam, black is hi beam.



Keyswitch. The slot in the top is for the wires. I soldered it all up before I realized it comes in from the top. So I needed the slot. Not bad for 30 minutes. Function over form.

[hadfield4wd]

Well some updates. New skid plate. Moose racing.



Also new frame guards, works connection. Before and after.









Also I was excited about my forks. I decided to not wait until fall. So I went ahead and had them valved and rebuilt by D’Orazio Dynamic Engineering Suspension Services, https://www.facebook.com/DDESuspension. He’s done a couple shocks for me as well. Apparently ’94 KX forks are considered vintage. I had a hard time finding springs for the right weight for them. I stumbled on Cannon Race Craft. http://www.Cannonracecraft.com. They custom make springs at very reasonable prices. I was very surprised to see the price. Well worth the phone call. They also were great to deal with and told me my springs would be custom wound to my exact specs and delivered in 3 – 4 weeks. Turns out they were way off. I had them in my hands in 2. Great customer service.

Also got a Galfer brake line.

Out with the old.



Old forks sitting next to new forks.



Installed including UFO fork guards.



She’s ready for our HMT ride in a couple weeks. I’ll be hitting some local stuff here in the next couple of days hopefully getting some video.

[hadfield4wd]

So I absolutely love the suspension on this thing. Very balanced.

I had custom retro 90’s graphics made. I really like the way they turned out. I’ll post pics when they are ready to be put on.

But Kawasaki for some strange reason primes and paints their aluminum swingarms. So all the scratches come out as black (primer color) I didn’t want to put new graphics on a painted, scratched swingarm. So it’s off and ready to be stripped. Plus this will keep me from riding it before my knee is ready.





We’re using this I thought it ironic that it’s “Aircraft Paint Remover” but the rear of the can says “Do Not Use On Aircraft”

[hadfield4wd]

Quick update. I'll go into detail later but love the look. Shiny swingarm and retro 90's graphics



Shrouds.



I have some more on order so no overall pics yet.
