[@duckworthatvandmxadventure6601]

Great vid. Nice to see a economy build with real life experience

[@Mrcbuilds]

Thank you Sir.

[@roryk.3568]

Absolutely, been using for years on high pressure areas and never had an issue. 👍 Love the details, everyone skips over the details

[@bobziegler1994]

Its your video,s that gave me the confidence to rebuild my ES . I learned more from you than 4 years in high school

[@Mrcbuilds]

Thanks for the kind words Bob, I am glad the videos have encouraged you and given you the confidence to tackle these small engines. You will find that the same skills you learned on these will apply to other projects you encounter the rest of your life. Thank you for sharing and supporting the channel.

[@phxfunfly9083]

Another great video - one great thing about living in the Arizona desert - I have bought several ATCs, VWs and other cars that spent their lives in AZ and no rust. My most recent 200x I bought sat in the sun for 20 years. Faded and cracking plastics and seat, but zero rust.

[@Mrcbuilds]

Thanks for watching. Rust works while you sleep. Lol

[@michaelkaizer6540]

Thanks so much for these videos.!! really ! I'm building a 350x now from parts.. complete engine teardown. It's my first time doing anything like this or any type of engine work and your videos for this machine have been so helpful !! Subscribed ! It's really cool that you do these videos and create this library for hacks like me. Ignore the trolls.

[@Mrcbuilds]

Be sure a get the manual and follow it . You will be fine. Thanks for watching all of mine are still running fine. Haters are gonna hate. Lol

[@atvseatexchange2176]

Determining why an engine failed is where the mechanics don't help themselves. I've seen motors from a 220 Bayou to a 900 twin from a SXS get the parts replaced and after a short time, it let go again. I found out about that 350d top end swap a few years ago but usually the hot shoes want every last bit of power for speed and bragging rights, not budget reality. Fantastic vid, I'm guessing you've spoken to the Dali Llama or meditate to remain so calm when thing goes wrong!

[@cliftonveasey1482]

Nice video, hate that even after all that work you had to pull it back out. But that's the way it works out sometimes. Keep up the good videos. Appreciate everything you teach us.

[@Mrcbuilds]

Yes, sir real world here. Lol thanks for watching and sharing.

[@porchonetwothreefour]

Another great video. Can’t wait for the next one. Thanks for all you do.

[@Mrcbuilds]

Thanks porchonetwpthreefour. Just waiting on a gasket set now. Thanks.

[@daryleduardo7055]

Dude its great to see someone fixing up that ol girl! Love the KISS shirt rock on 🤘🤘🤘

[@Mrcbuilds]

Thanks Daryl, yeah I'm hooked on these ol things. Rock and roll all night Honda everyday!

[@MichiganQuadTrailsTales]

Great Video! Sucks to go through all that work, and find it did not fix it, and have to take it all apart again.

[@Mrcbuilds]

Yes it does, it can take the wind out of your sails quick. But I will figure it out. Lol thanks for watching

[@benschlack5814]

Hey it happens I built a rm80 engine split cases and all the good stuff the crank bearings were packed in grease for shipping and storage purposes I think but either way I never cleaned it off the new bearings and when the engine warmed up it blew a crank seal when the grease hydrauliced also made a mess inside the case's lol lots of fun learning that's what it's all about

[@Mrcbuilds]

You know how it is, you have to take it in stride. Some are harder than others. But there all fun and I learn a little more each time.

[@cj7fun579]

I can't believe after overhauling that engine that the kick start is still stiff. It's almost like something is out of alignment or something simple that's binding. Sorry to see you go through all that and start over again, man I hate doing that myself, I know what it feels like. Hopefully the problem shows up.

[@Mrcbuilds]

I'm thinking it's an alignment issue in the trans.

[@johnmcnamara4880]

another great how to video! just a comment about spring compressors and eye protection! even though the springs are small, things can go wrong in a hurry.

[@Mrcbuilds]

Your right, good call. Thanks for watching.

[@markengley8839]

Love your channel and videos. This one sure is interesting. You said you were in Florida. Have you ever shared where? I watched the video where you went on a road trip for a 200x and you drove over the Escambia Bay bridge on I-10. I live in Milton, so you drove right by my exit (Hwy 87) on the video. Always wanted to ask you where you were coming from and going to on that video, but just can’t find that one right now…..Looking forward to the next one! I am a subscriber and shopping for a 350x of my own….Looks Iike it’s going to take quite a pile of shekels to reel one in, along with a road trip….

[@Mrcbuilds]

Hey mark, no I dont say where exactly on purpose, you know just in case. 350x are hard to find and when you do usually not cheap. I have a friend in lake city who seals in 350x, look up facebook marketplace in lake city, he post them there for sale, or join his FB group " king of the hill" his name is Lou.

[@larrymitchell7958]

Excellent information! Keep it up..

[@Mrcbuilds]

Thanks you Sir

[@smallmiraclesgarage622]

Look into time sert repair kits for the plug repair. they work great! i use them a lot, they are 100x better then a helicoil

[@Mrcbuilds]

I will try that thanks!

[@223cycles2]

Awesome Stuff. A lot of really great info here. Get all your practice in so I can send you my 86 engine to go through. 😂

[@Mrcbuilds]

Anytime for you sir!

[@phil463]

For future reference, a heli coil is NOT your only option. Small engine guys actually will turn their old spark plugs into a tap and fix the threads. donyboy73 did a video of how to do it years ago, and it has worked like a charm for me, and many others as well. I would suggest finding the video BUT what they do is (BTW, he learned this trick from a car racer) they cut "tap grooves" into the threads of the old plug with a hacksaw or whatever, then screw it down into plug with (grease on threads to catch any shavings) and voila, you have a rethreaded, fixed stripped spark plug hole

[@Mrcbuilds]

There always more than 1 way to skin a cat. Thanks for sharing

[@JasonSmith-bc1qh]

Your videos are the best! Thank you for taking the time to do this! I have an off topic question, I need a timing chain and guides for a 85 trx 250. Can you recommend a place to purchase this stuff and is the motor in the 250 three wheelers the same motor that's in the trx 250? Thanks again!

[@Mrcbuilds]

Search ebay, I only use D.I.D. brand timing chains. Guides a company called G&H sells a nice pair.

[@JasonSmith-bc1qh]

Thank you!

[@ronniewilliz153]

Was the wrist pin wear from the piston slap that was from the difference in piston size an sleeve size ? An I wonder if bearing was locked up on the kicker shaft or there's chunks of teeth in the cases. An are you changing out the crank bearings since you have it open ? Never had a 350 but had a quite a few of the 200s the 250x was my favorite you could throw that thing around like nothing the 350 was quite a bit heavier lol. I also miss my xr200. I love Hondas my self as well. I also love the 80s an 90s stuff better then the new stuff. Don't get me wrong fuel injected is nice an all but the nostalgia of the older stuff is awesome.

[@Mrcbuilds]

Hi Ronnie, no chunks, no teeth. Just a lot of sludge. I cant find anything really wrong with the kicker or its parts. I have another trans, kicker and case that will be going back together.

[@mister_fourfiftyfour]

Good vid! How much do you charge to rebuild an 86 350x motor?

[@Mrcbuilds]

Hi Creek, I really dont do work for others. But i appreciate the confidence in my work.

[@mikeshobbiesandrandomstuff]

Someone once told me that if the decompression mechanism isn't setup correctly you can have a really difficult time trying to turn it over

[@Mrcbuilds]

Your right Mike the decomp makes a big difference, this was hard to kick even with the plug out. I feel it's something in the trans.

[@mikeshobbiesandrandomstuff]

@@Mrcbuilds agreed definitely looking forward to the next one.

[@82airfouler53]

I bought a nice looking and running 85 350x a while back an I've rode it a couple time an put it up because it has a ticking rattle thing going on I took it to our local Halls Motorsports they adjusted the valves but it still ticks or rattles I'm worried it's starving for oil like yours how do I check that screen you said gets clogged up ? The bike runs excellent other than that.

[@Mrcbuilds]

Pull the right side case, the screen is located on the bottom, pull it out clean it and slide it back in. Download the free manual, order a gasket it's not that hard of a job.

[@timothyburrier6684]

So I had a 86 would start 2 kicks every time when cold. Would run fine. If I shut it off it would start for shit when hot or even warm. It wasn't running lean or rich. Got to the point I just sold it broke my heart. It was rebuild at a honda shop. No one could figure it out. That was 4 years ago and I still loose sleep over it. Anyone have this issue before. Searched 3ww and the rest of internet never found a warm start issue. I tried cdi swaps idk. It just sucked

[@Mrcbuilds]

Hi Timothy, I would start with a the coil and the stator, heat affects both of these items. The next time you have a hot start issue, take voltage readings when the unit it hot and again when its cold. Heat issue can be tricky, a compression test would rule out the engine, and bit of starting fluid would rule out the carb and fuel delivery, this only leaves electrical.

[@daver681]

I have a 85 model 250sx and the gear shifter hangs down every time I shift it and I have to pull it back up, where is the return spring and which side of the engine do you remove to access and fix it, Thanks.

[@Mrcbuilds]

I would pull the left side and inspect the spring on the shift shaft top of page 9-0 in the sx service manuel.www.oscarmayer.net/atc/manuals/

[@daver681]

@@Mrcbuilds Thank you so much.

[@jake_of_the_jungle9840]

I just hit a stump with my 200x and not I think I need new forks or something, my wheel was crooked I got it to straighten a little but just not perfect. Any ideas or input on what I should do bc I love the thing

[@Mrcbuilds]

Check your forks you could have bent 1 or both. There really isnt much to go wrong with the frontend other than bearings.

[@onsiteautorepair]

Will 9 inch wheels fit on a 1985 200s

[@Mrcbuilds]

Yes, as long as the bolt pattern is the same, for the rear you can swap the hubs, not so easy to change the front.

[@dubbedmodz7253]

So the 200 timing chain fits the 350x?????

[@dubbedmodz7253]

This can't be right, please tell me

[@Mrcbuilds]

No that's not correct.

[@dubbedmodz7253]

Do you know a chain that will work with the 350x

[@Mrcbuilds]

@@dubbedmodz7253 go to ebay search honda 350x timing chain, a d.i.d. brand will pop up.
