atc 350x

[Schultz#508#]

im about to buy a 86 ATC350x it runs but doesnt have rear hubs which that wont be a problem to get the plastic is in pretty good shape theres about a 2 inch crack in one side of the rear. it just needs a few things to be nice but i didnt know really what one is worth. any comments or suggestions

[deathman53]

$1000-$2500 all depending on condition. Thats if its like you say.

[dxcody]

deathman prettty much called it, anywhere from $1000 to $2500- and i know thats a pretty big gap, but if you posted a picture, there are some guys on here that could tell you exactly how much its worth.

It may be a little lower than $1000 idk

Im not much of a 3wheeler guy, but i have spent enough time on craigslist to price about anythin with a motor lol.

[deathman53]

just a tidbit of info, 85-89 250r rear hubs are the same as 85/86 350x. They are exact or a slightly different offset or color, only difference. When you check it, there is a very important thing to look at: if it smokes at all, there is a good chance that the cam journal is gone or valve seals/trane needs work. 350x's have a problems with top end oiling, in 86 it got better, but not solved. Revving it high(extended times), extended wheelies and revving it so high until you shift are the primary reasons for the oiling failure. The head is discontinued(for 10 years) and commands a high buck. something to thing about.

thanks guys ill see if i can get a pic of it up here it dirty but itll wash

[tripicana]

bought my 86 350x for $350
put a new clutch in it, and have only changed the oil.

I agree with the first part.


The second part...no


Me and a bunch of my friends bought our 350X's brand new, I had the 85 they had the 86's. We lived way out in the country so dirt road riding was the norm...all day 6th gear wide open, two of my friends are wheelie gods...lol...these guys could go as long as they wanted to, through all the gears...

None of us ever had problems with the heads...I owed that same 85 350X up untill a few years back when my ex-wife stole it...never once had to replace the head becuase of oiling issues.

350X heads get destroyed because people did poor maintenence or used crappy oil's

[wrencher]

isnt the oil pump located at the front of the motor on the 350x? so while the machine is in a wheelie position how does the oil pump pick up oil? wouldnt gravity pull the oil away from the oil pump and the pickup?

what about the cam, does it have bearings? or does the STEEL cam run directly on aluminum journals? werent the 350xs notorious for having damage to the cam journals? did the 250xs have the same problems? they were almost identical in design to the 350s with the exception of having BEARINGS on the cams. i wonder why 250xs dont have so many head issues... i mean are all 250x owners big on oil changes and 350x owners not? thats the problem? kinda odd that 350x owners were so lazy and 250x owners were not dont you think?

[Black Sheep]

Yes, but, the 350X holds over 2 quarts of oil. even in a wheelie position oil will get picked up by the pump.

As far as the rest of you post, apples to oranges but, I will entertain it with a reply.

I don't recall ever saying anything about it being the BEST design. I just said it is not the problem people make it out to be. Yes, a bearing cam will last longer and I never said otherwise. But, in my experiance in owning, maintaining, and making a living of 350X's for 20 some odd years...I have only seen cam damage from two things...low oil or oil filter installed wrong.

With that said a 250x will tolerate a low oil amount more then a 350X will because of the bearing cam. In my experiance most ATV owners are real terrible on maintenence.

I would love to hear peoples opinions on why we were able to get away with beating the living crap out of our 350X's, holding them pinned in 6th for hours at a time and yet never had a cam problem.

[wrencher]

if its not the problem people make it out to be, then go ahead and buy a few 350x heads. lets see how many you can find without damage to the journals.

350xs had a design flaw, yes they were good motors, yes they were fast for the time, but they were flawed, end of story.

[Black Sheep]

How many you want...I have over a dozen. More 350X's got parted out because of the frame then the engine.

I would like your "expert" opinion why I never had a problem in 20+ years.

If it was a "FLAW" then it would happen to all of them...as it stands the 350X is one of teh most popular ATC's still out there today...20 some years later...why are they not destroyed.

Plain and simple, the 350X was the high performance, high manitenence 4 stroke of the day...call it a pre 450 era engine...it requires more maintenence then your average trail engine designed four stroke...amd if you don't...you pay.

[wrencher]

bla bla bla..whatever dude. you're right they were not flawed. none of them had issues with the heads, its all a lie, they were perfect, you win.

your the "pro"

I'm sorry of you don't like my response or experience but, you haven't proven a flaw. All you have done is make statements...based on what, some people having problems. Go check out the 3 wheeler message boards if you don't belive me, ask them what the "flaw" of the 350X is. They will all tell you the same thing...FRAME!!! Almost everyone that has been ridden has cracked in the same spot. That is a flaw...when you know it will happen.

[sly400ex]

Haha...entertaining. But I'm thinking Black Sheep knows what he is talking about here.

[speedracer350X]

I feel your pain fella, started out on ATC's in the 80's, (yes I'm old!) Had an 87 200X, my favorite machine, got a well used 86 350X in 1997, like you said, I was the 3rd owner at the time, and the machine was not well maintained or taken care of. Gotta open the history book for all the youngsters, no sport quads at the time, only Banshee's and Warriors, and in my opinion, they weren't the best offered. Still was on 3 wheels, didn't even buy my first 4 wheeler until 2003, I know the Honda 250R was probably the best quad of all time, actually never rode one. Was never a fan of 2 strokes, to me they just weren't made for the "coal region" here in PA. Had my 350X rebuilt in 2000, and yes, the cam journal was shot, prob due to little or any maint. performed. Once it was re-machined and rebuilt, ran like a champ. Usually neck and neck when drag racing my buddy on his 400EX when he first got one in the spring of 2000. But these youngsters gotta remember, which I didn't know until just lately, the reason no sport machines were allowed to be produced was from some 10 year law spanning from 1988-1998, right after they banned 3 wheelers. Hence Honda released the 400EX in the fall of '98 labled as a 1999 model. But during the time frame mentioned, we had to ride what we had, and 3 wheelers were still holding their own, esp. if that's what you started riding on.

Ok, not including the dozen or so I have...

Didn't take long to find this one on ebay http://www.ebay.com/itm/Honda-ATC-350X-350-X-ATC350X-TRX350-TRX-350-Cylinder-Head-Cam-1985-85-/150708953671?pt=Motors_ATV_Parts_Accessories&vxp=mtr&hash=item2316f42247 470.00 and you not only get the head but the valves, springs, cam, cam sprocket, rockers. pretty good deal.

oh, look at that...another one http://www.ebay.com/itm/85-HONDA-ATC-350X-CYLINDER-HEAD-VALVES-/200684712432?pt=Motors_ATV_Parts_Accessories&vxp=mtr&hash=item2eb9bdb1f0 only 185.00 for this one including valves, springs, and rockers

damn, found another one http://www.ebay.com/itm/HONDA-TRX350-350-4X4-ATC350X-350X-CYLINDER-HEAD-ASSY-Z-/400208566288?pt=Motors_ATV_Parts_Accessories&vxp=mtr&hash=item5d2e4a1810 this one is reconditioned so it's a little pricey

That was just a quick 2 sec. ebay search on "ATC 350X head" I'm pretty sure with different searches I could find more


refined my search a little bit a voila http://www.ebay.com/itm/HONDA-ATC-350X-HEAD-EXTRA-PARTS-1985-86-/200687306357?pt=Motorcycles_Parts_Accessories&vxp=mtr&hash=item2eb9e54675 only 249.00

This is just down right crazy...a forum dedicated to the 350X and not one person is looking for a head in the wanted secition http://www.honda350x.com/forum/forumdisplay.php?f=33&order=desc Just about every other part on a 350X is asked for though

the 450 is so awesome...those 350s are super nice too...i never was much for the 350x...i loved the 200x's and 85-86 250r's ...i always felt like the 350 was a tank, most of the ones i came across hadnt been maintained and had issues with the cam journals and other nonsense


i know this isnt a 200x thread but heres my old 83-85 beater i had back in the day

trikes are by far the most fun imo

[HondaPohl]

I guess wrencher decided to shut his pie hole.

[CHAR250R]

I have had 6 1986 350x's. No head issues. If you maintain things and use top notch oil and parts, things can last forever. It's the 350X's that are beat on day in and day out with little or no maintenance that fail.

[DVXchic]

That 450X is friggen sexy :eek2:

well im kickin myself for waiting to buy it, he sold it for 250 bucks and it ran
