How to fix a smokey 4 stroke motorbike / quad bike motor. TRX350 recon

My Honda trx350 foreman 4 wheeler was blowing a lot of smoke so I stripped it down and found a badly scored bore and worn stem seals. Thought I'd make a vid for anyone looking to fix their smokey motor. The process is similar with most small air cooled 4 strokes.
Took about 6 hours to do the work and cost around $140 for parts, fairly simple job for anyone with a good tool kit and mechanical skills.

Great stuff, Marty, but I prefer your vids when you’re talking. From your descriptions to your wit to your accent (I live in Iowa...,) your narration adds much. Aside, you are amazing.

[@captnsquid8151]

It has always amazed me the expense and effort people put into repairs and skip test and checks. Then forget wrist pin retainer. Then his loss and your gain. The valve stem seals he reused made me laugh out loud. Great vid.

[@AkatarawaJapan]

Mate, I don’t know how you know all this stuff but you are the Mustie1 of New Zealand. Thanks for the vids-always interesting.

[@MartyT]

Thanks mate, You can learn most things on the net these days

[@IndieAmericaTV]

@@MartyT Being called the Mustie1 of NZed is pretty sweet.

[@TedBishop1]

high praise indeed

[@curlyzst]

Here a year later and I'm pretty sure it's because of Mustie1. Mustie1 knows his engines, Marty T knows his..everything.

[@brotherkhan2885]

Mustie 1 is the best

[@physicsguybrian]

Marty, I live in San Diego, CA...not a bad place to live but MY GOODNESS man your land, your views, simply breath-taking!!!! PLEASE never take for granted just how damned beautiful your surroundings are. Thank you for all the great videos and the constant reminders to "get out there and do something" worthwhile...by good example every video! Cheers!

I did this on a 125 Honda when my Dad died leaving it to me when I was 15 in 1975. No doubt I made lots of mistakes but it worked well. I hammered the poor bike in the bush and beaches. So I had to rebuild the 125 about every year 10yrs until I could afford bigger bikes. But never found better bikes. They are still making those machines.

[@ronaldheit196]

It's a serious pleasure watching your vids. You get things done on equipment that most people would give up on. It's pure ingenuity at work on your projects.

[@marcryvon]

Honda engines are simply the best. Especially the older ones, still made in Japan. You're a very talented man. Like another comment here, you ARE the confirmed Mustie1 of NZ. 👍

[@rhiantaylor3446]

Can't have too much video footage of your amazing countryside !

[@ethanbible5264]

Man that place there at the end of the video with the ocean in the background would be a perfect spot for a log cabin home

There are no short cuts to a job well done. Great to watch your methodical servicing, so refreshing. Cheers!

I have an 1987 Trx Honda 350D in mint condition with low miles. Had it for many years and still love it. Thanks for saving another one

[@larannar123]

That's superb mechanical skills!!🖒 Truly impressed by your knowledge, not gonna lie,your a pretty remarkable guy Marty...😎

[@M21L35]

YIKES! This vid. just takes it over the top! I should've expected your engine rebuilding talents to be commensurate w/your equipment knowledge & operating expertise. And of course....you've all the necessary tools to accomplish any task you encounter!

[@Chr.U.Cas2216]

Dear Marty T. 👍👌👏 Very well done again and as always. Congrats for having so much skills. As always: Thanks a lot for making teaching recording editing uploading and sharing. Best regards luck and health.

[@duard1220]

Great video! I was waiting to see how you compressed the rings to get them into the jug, but all of a sudden it was done. Magic! LOL! Maybe next time..... Thanks Marty!

[@tomherring9104]

The jug is tapered so the rings just compress as you slide it down over the piston.

[@chazer200]

You are obviously a very skilled mechanic. I find it oddly satisfying to see you do everything needed without the 20 minute explanation I don't need. BUT, I would like a little more personality to your vids. Loved the HGV recovery, you have a new sub for sure. Also love the Rams LOL so good. Just give us a little more YOU. Who are you? Where are you? (New Zealand of course) but that adds to the intrigue... Just give Us a little more about who we are watching and this may explode! Total PROPS!!!

[@TedBishop1]

" a wee while ago " I love it !

[@waifuracer6516]

As a mechanic, this is the kind of ASMR Im into :D

Hello there. The Engine sound's good and that Vue is beautiful.

[@rogerwilliamcoates5724]

That takes me down memory lane. When you've had Old Fords, especially side valves, you end up having to do all that kind of stuff. Think I still have my Valve Spring Compressor somewhere along with my lapping tool and grinding paste...

[@mausplan3890]

Same here. Memory lane ,as a first year apprentice in OZ we had to learn how to pour and scrape to size babbit bearings

[@brianmoore5498]

my goodness what a beautiful view !

[@andysaunders3708]

Hey, that looks like it's relatively simple to work on. I had a Suzuki King Quad 300, which went fine, but it developed a loud whine in 3rd gear. The dealer said it was a 2 day job to get the engine out, and from what I saw, it looked like it. So it got sold as is - got what I paid for it, ($1800), as the repair bill was just nuts. Great little quad, though not popular with some people because af the swing axles at the rear.

[@dustyfarmer]

Great quad the TRX350, I've got the FM 4x4 version, keep the engine oil & filter changes at 100hr intervals as the oil runs in the gearbox & clutch as well. I'd fit new tyres as they are a safety issue, you don't want to be slipping & sliding especially in hilly country with a 2wd only.

[@richysee]

Great work and attention to detail. Performance should be like brand new.

[@eddiesheeran5791]

Nice work! I'm about to do the same job on a 454 bearcat.

That's a Rancher homie. Bet it took a while to burn the oil out of the muffler. Nice job

[@MartyT]

You must be in america? they're just called trx350 here. yeah she smoked for a few hours till the oil burnt off

[@paulmurray129]

Really enjoyed your vid. Paul Liverpool cheers

[@cecilhoover6175]

A easier way to seat the valves is I drille on the the back side in reverse until it is seated properly

[@AlessandroGenTLe]

You remind me when I rebuilt a Suzuki GS500 for my girlfriend. Good times those :D

[@H4rleyBoy]

Maybe one day you could show how to do the valve stem oils seals with the head still on.

[@w.w.2restorations.vehicles698]

Mine smoke at higher rpm but very hard to notice at mid throttle..no smoke when idle too. What could be the problem?

[@MartyT]

Rings, valve stem seals?

[@TubolMotoadventures]

@@MartyT it could be.. Anyway i just ordered intake and exhaust valve seal along with piston kit

$83 USD and some change. That’s cheap! 😏

Possibly, unless he forgot to install it
