1985 Honda TRX250 Fourtrax info.


Recommended Posts

I haven't rode in a very long time and a friend is selling me a 1985 TRX he obtained through family that is in pristine condition. I have a few questions since he can't find the manual- and sorry if I come off dumb or "noobish".

1) Gears- these are 5 speed right? 5 down and up is back to neutral?

2) 4 stroke 10-w30 for oil? How much?

3) spark gap?

Thanks for your time.

Correct, push all the way down until it won't click any more and that is 1st,About half a click up will be nuetral. Kind of hard to find on some bikes. I have a friend who has the same quad I do. I find nuetral no problem, he CANNOT get nuetral if the bike is on or running. All the gears are up except 1st is down. When down shifting everything is down.

Just remember, there are no dumb questions. Just dumb people who DON'T ask and end up with a busted quad because they took a guess.

Yeah, it's not a 250r it's a trx250 and really nice. I haven't ridden it yet, I want to make sure I know everything about it mechanically because I don't want to fry the clutch or anything else.

I'm sure I'll find neutral, I used to have a 250 Big Red about 20 years ago and never remember having a problem with it- it's just been a while.

Here's a photo of it.

One more question, I found a few places but anyone know where you can get:

A arm bushings

Swing arm bushings

King Pin bearings and

Tie rod ends for these 86 TRX250's?

The front end is a tad bit wobbly and I want to have them all replaced. I found one place hat have them, but I'm not sure if they have the TRX250- they do list the TRX250X and R models though.

Welcome to the site, don't feel dumb for asking any questions. Yes 10-w30 will work just fine, it's what I use. The shifting is usually 1 down 4 up with nuetral between 1 and 2. Don't know about the gap but the oil should have either a viewing glass on the side of the motor or a dip stick.

Do you put any additives in the oil? I was told additives may be required?
