This is a build log, not a build up.
I enjoy working on these things, I buy them, fix them and sell them, I keep some for myself but mostly to sell.
I keep a ledger of money spent and a tally to see if I made or lost.
My time is free, since I enjoy it and always learn something along the way, you could say its the cost of
an education, otherwise its purchase + parts= Profits?
I am not a mechanic, I just own tools and like to get dirty.

Today I picked this gem up, It is a real test
Can I make a dollar off of it? we will see.
Worst case I can part it out, so if you need any parts
let me know,

1993 Honda Fourtrax 300 full time 4x4.
I will update as I go.

Is it 1st gen 93 or 2nd gen 93 (single tube under tank or split frame?)

Doesn't look bad. Floorboards will always get you a nice bit.

Hi Jeep
I guess its a second gen split frame.

So tear down begins.

I have a video but cant post it (mp4)?
so I will write it out.
Previous owner said it just stopped a few years ago, and hasn't moved. we will see

I checked the oil, pulled the plug, it was orange. lol
sprayed the cylinder down with PB blaster
hooked up a battery charger
checked all the fuses
Turned the key
hit the button nothing!
turned on the lights nothing?
found a tiny small red wire pulled loose from the start relay, plugged it back in.
hit the button Wamo! the starter spins
screwed in the compression tester and spun it about 10 revolutions
it maxed out as 80 psi and held that for 20 min. while i removed and cleaned the dirt dobbers out of the float bowl of the carb. (i used toilet bowl cleaner to clean carbs it works great)
Installed the carb and rigged up some gas in a bottle.
primed the carb and filled the bowl with fuel and hit the button.

Pause for suspense vroooooom she is alive.
after listening to it and letting it idle and warm up, Im sure the valves need adjusting and the carb is not perfect. There is a wirling noise after you shut it off sounds like its coming from the front of the engine? I have no idea.
also when pushing it I heard a clunky sound coming from the front end diff area, we will address that soon enough.

All and all, a great night, from broken down for several years to starting up and idling
I will clean the tank and get some proper fuel for it, set the valves and change the oil, at this point it looks like I can save her, and make a buck, so that is the plan.

new used fenders
new wheels and tires
a good service (oil/filters/carb/plug)
a new master cylinder and lever
clean and adjust the brakes
address the front clunky noise
address the wirlly noise.

MrC.

Goober that is a beautiful machine, I like the green wheels, is that a factory option?
I am just trying to save this one, so far so good.
I am trying not to get attached to it. lol
I have been enjoying my 98 450es.
Here are some pics of tonights work.
I cleaned the tank and it looks to be salvageable.
found someone has been in the brakes recently, the rear is dragging and there is a clunk in the rear drive shaft or diff I cant tell yet.
all diffs and t case had fluid in them, so at least there arnt dry.

Thanks for noticing the olive drab powder coating; thought it might inspire you in your hunt for new wheels.

These are the original wheels and they had the original Goodyears on them—which i think you have one. They were silver but flaking and the black primer was peeling too. The powdercoater couldn’t get a silver i liked And didn’t want black. Very happy with the match

More of the same, The more it runs the better it sounds.
Shadetree may be right again, the binding is coming from the rear diff, the t-case and front diff, I changed fluid and they feel fine, So what are my options? replace bearings in the rear diff? replace ring and pinion? or swap the entire unit? Can I do it? basic hand tools?


I Cleaned the brakes (waiting on brake lever now) Spent two hours cleaning the tank, installed a fuel filter to be safe. I found some aluminum factory rhino wheels 7.5x12 and 6x12 4x110 pattern those and some matching tires should bring this pig into the 21st century looks wise. I will upload a pic of the plastics, they are a mess. I really don't know what to do about them.

The whirling noise has stopped, after the first couple starts it went away, may be it needed to be ran, sitting 5 years may have gotten a little stiff. While on jack stands and running, I shifted through all the gears and even into reverse, all gears works fine no issues (at least with no load on them).

Lets see what tomorrow brings. I want to see it on the ground and moving under its own power!

changing the ring gear and pinion gear in the rear diff is not too hard ?, the worst part is replacing the pinion needle bearing !. it wont' be easy to get the old pinion needle bearing out, but it can be done !.

So today has been fun, I scored some aluminum wheels and some new take off 25in tall tires.
Found a guy on eBay, who rebuilds the rear diffs for $185 and that includes a warranty and free return shipping.
Also talked to the guy in Arkansas who has new plastics, we are working on what shipping through fastenal might be for a full set.
fingers crossed on that. locally I get get some used plastics from a junk yard but there then there 26 years old.

I ran through all the gears and reverse all the dash lights work as they should and the headlight switch is working along with high and low, the bulbs are toast.

So now it comes down to plastics, rear diff, and a leaky front driveshaft seal (t-case side), it didn't start leaking until after I changed the fluid. lol.

Below you will see the new wheels, I may keep these they weight almost nothing, the terrible state of the plastics and the new knobby tires 25in on the left side of my v treads.
Enjoy the photos

Parts

I can not find the seal part number anywhere for the front output drive shaft of the transfercase.

Also would any other fender set or model would fit my 93 trx300. something newer? something cheaper?

Thanks WIlson

Partzilla didn't list it. Thank you.
I feel like there should be a 6ft privacy fence between us. Lol
Thanks again

it was listed under the drive shaft on partzilla, just like everything else, they are removing parts for the trx300's slowly one part at a time, wont be long, and all parts for them will not be around.

Well the first gens are harder to find parts for, and you can't use a Wide Open 424 on them without modifying it to fit because nobody makes a 424 for the first gens anymore.

I'm not sure if there's a benefit for the actual first gen frames in the mud, but some people seem to prefer the 1st gen bikes for mud bikes. The 88's had a BR cam in them from the factory, but I don't think any of the other 1st gens did, but I do think the 1st gen CDI's allowed for more RPM's.
@mac102004 could probably either verify what I've said, or tell me I'm wrong on every point.
