Tacoma's "Project 300" build

tacoma_20022010-08-10 07:48:01 +0000 #1
Well here I go with my long awaited build thread.

I had dropped by the local ATV shop to see if I could get a lead on a TRX300FW to build as my mud bike when I spotted this '99 Honda 300 2wd sitting out back of the shop on 4 flats...long story short I opened my mouth and bought it .

As you all know its getting harder and harder to find a 300 reasonable, so when I brought this one home (after draining the old gas and replacing with new of course) and kicked it once it started right up !

I dont have any pictures of it when I brought it home, but this one should suffice for now.

Here I had already Pressure washed/degreased, swapped out wheels with foreman rear/300 4x4 front (so I could roll it around), installed a new gearshift lever (didn't have one to begin with), and removed the racks/plastic.

I'll post pictures of the rest of my build when I get access to DSL/Highspeed.

You gonna convert it to a four wheel drive ?

Actually, I've called around on some junk 300FW's trying to get an idea of how much I'd have in a 4x4 conversion. Turns out (unless I find one super super cheap) that I'll come out better by leaving this one 2x4 and buying a 4x4 and building it also.

I'm currently midway through the build, but I wont tell you about it until I can post some pics . Just waiting on gears and some odd and in parts to button er' all up.

My parts will be here today...

After letting it run for a while with transmission fluid in the gas it smoked a little. I changed out the gas a few days back, and it still smoked a little, but not as much. I'm going to run it after the diff install with no plastic, and if it still smokes after a hour or so of riding you'll get to see....

Weisco piston


'88 Cam

BR timing chain

Clutch kit


300ex carb

Good luck on this restore. I'm going to start a thread like this soon and chronicle my restore on my 1985 ATC70. It runs great. I ride it often.

UPS was so kind to drop my parts off about half an hour ago.

All parts are Genuine Honda and the gears count out to be a 3.88888889 therefore making them 3.88's.

Tacoma I would seriously reconsider running the 300EX carb. You aren't going to be making enough power to need that carb. It's going to be dumping a lot of fuel into the motor. Probably a lot more than needed. Unless you got a good deal on it or the stock carb is shot!
tacoma_20022010-08-10 09:23:58 +0000 #11
Depending on what bore size I have to jump to will depend on the carb. Maybe just the stock carb with a jet kit. If I only have to go .020 over or so I wont use it, but if I decide/have to jump to .060-.080 over, then I'll probably do a carb upgrade of some kind to not only meet the fuel demands for the bigger bore, but the cam also.

I appreciate the idea's fellas keep um comin'.

Feel free to elaborate.
