The seat cover you got is for a Honda 300 fourtrax utility they were made 88-00 and the trx300ex was made 93-09 I believe
I like everything you’re doing. A couple suggestions: measure ring gap after honing. You should also start measuring for cylinder out-of-round. Keep up the good work.
Literally the Cris fix’s of four wheelers ☝🏻☝🏻
Cmon dude you can do it, you gotta get em out of there and do the job right like you have been doing in ur vids..dont start half assn now you come to far dude..
Thats insane how you heat gunned the plastics and made them free of oxidation! Keep on the good videos!
So awesome to see an actual engineer working on a simple stupid bike that is actually an engineering marvel and a wonder. How about those valves being spotted ? Excellent , loving it ! Superstar
Thanks for the videos man. I watch them all. Just a tip for you when checking the ring gaps. Use the piston to press the ring in there. It guarantees the ring is perfectly level in the bore for you to check the gap.
You definitely brought this one back from the dead good job Joe ! It'll be a great learner quad for someone.
it always feels like when your torque tightening bolts that they will snap lol
Yeah man, that seat cover is for a TRX, not an EX. The TRX is the utility style quad. Easy mistake to make, but you can’t really blame that on the seat cover company.
Yeah I realized that after I was editing lol. I got the right one ordered now.
Its a trx300ex there mr bwat
I think you're confusing TRX with FourTrax. TRX is the sport quads, like trx 250, trx 450r, etc. Fourtrax is utility.
Yeah it’s a trx300ex but the seat cover didn’t say ex so the cover was probably for something like a fourtracks
Now THAT's some serious "Shade tree" right there.
I LOVE your videos fixing these quads and bikes. I'll pass on something I learned from another guy (I think all of us guys doing fixit videos can share a wealth of info and experience), might have been Rocky Mountain Redneck (I can't remember for sure), but he was having trouble getting broken off seized bolts out, and used a set of Parrot Pliers. I'd never heard of them before. It worked for him, but I didn't really have a lot of faith in it, but as I seem to have a tool fetish (I have tools I can't even pronounce the name of), I ordered a set just to have them. Holy crap, those things work incredibly well. I have yet to find a bolt that has at least 1/4" sticking out I couldn't get out with those things. Heat it up like Matt Mazzella said below, grab it with those pliers, and they grip like nobody's business. Looking forward to your next one. Kudo's man.
To get in reverse you push in the little button on top of the clutch lever then pull in the clutch, third step is pull up on lever. Pretty complicated for a reverse procedure if you ask me 😂
Looked like so much fun. Takes me back 30 years with the Rm line up. Love to see more trail camera footage of the critters on your land.
Yeah honing cylinder is supposed to be a simple light low rpm couple passes just to get slight crossed hashmarks ... thats how i learned it anyway ... could be wrong
When you remove valves from a head, make sure you deburr the stem where the keepers sit in the groove, oftentimes there will be tiny bits of metal sticking up, causing it to hang up in the guide and possibly damaging it upon forcible removal of the valve. A small file or whetstone takes these right off and allows the valve to slide right out.
Great video on this overhaul!
Second this
Great job again joe they plastics came up like new cracking little quad for some great fun on well done mate take care looking forward to the next one 🔧🔧🔧👍👌
Perfect way to start the day, thanks for the upload 👌🏾
I had a yellow 300ex and wish I never got rid of it, had a full fmf exhaust and bigger jets to accommodate the exhaust, thing was so much fun and great for learning slow wheelies. Not the fastest quads by any means but definitely tons of fun
I heat gunned the plastics too on my 95 klx650. It looked pink and purple before bow it looks a descent original red. Great work i enjoy your content man. Wrenching is awesome
Always liked the 250X / 300EX platform, with Reverse its a winner in my book,
I'm always surprised you don't use a piston to check that a ring is "square" in the cylinder before checking a ring gap.
He used to use a piston all the time in previous videos. After you check the ring gap 100 times, you get a feel for when the rings are in the correct position to check the gap.
He used to he's done enough of em now to know
Cool fix !! She came right back around !!
You should invest in a decent size drill press to Hone your cylinders. When you do it by hand you stand a good chance of making your cylinder egg shaped.also,check your end gap by using the piston to squar up the ring,and do it after you have honed the cylinder.the reason the valves had a lip on them is because the actual valve seats were worn out,causing the valve clearance to b to tight.
Man come on u are just hone it u ant boring it lol U build a v 8 u use a drill press to hone it no u don’t if it’s that bad u bore it
@@shotgunz1248 no,actually I send a v8 to a automotive machine shop.just trying to help the kid out in doing proper procedures.
@@darrinwoodward14 ultimately it doesent matter. I’ve honed big scratches out of cylinders by hand no problem
Gotta use the clutch and button with the reverse lever. Be safe brother :)
Love your content bud, always anxious for the next video! Keep up the awesome videos
Thanks for watching!
Hey bud on those jug bolt you can get them out. By drilling holes into them for tapping A easy out into the bolt hole predrilled inside of it. Then use propane tourche to heat the outside area up to expand thread space. Then use A wrench to loosen up the bolts with slowly.
Just to let you know you should push the ring down with piston to make sure the rings are straight and ring gap is 100% true
He does bud
To get it into reverse: trans in neutral, push red "R" button on clutch lever then pull clutch in. Then lift up on the reverse lever, put shifter into 1st and she'll go into reverse. Let out the clutch and away you go
Never understood why the reverse lever was on the same side as the clutch. It can get a bit awkward to engage. That being said, I miss my lil 300.
@@buttermule yea I have a 1987 trx250x and the reverse mechanism is much easier you use your heel to pull it up
If make a longer shifter you can use the extra shifter to eliminate the funky reverse lever, you'll have 2 shifters but it works
@@buttermule yeah definitely a weird setup!
@@2vintage you dont put in into first to go into reverse, you press the red "R" (I noticed that your had dry rotted off so its just a metal post) and pull the clutch in while in neutral, then just pull up on the lever and it should click into reverse. But youve probably figured it out by now but, oh whale. (Edit: Im a dum dum stuoid brain, i just saw you do it, dont just the gun on commenting lmao)
When you do old seats and the foam is dries out and rough, glue a layer or comforter batting to go over the foam before you staple the seat cover on. The seat cover you got was for a fourtrax, you need one for a trx300ex sportrax.
Man, it's a good thing you decided to change the valve guides. That intake valve was stuck! You should consider a little assembly lube on the top end for first startup. Great vid sir!
What's the tool called? And is there one to remove a stuck wrist pin on the piston?
May want to invest in a ridge reamer to take care of the lip at the top of the cylinders. Awesome job as usual.
Find complete front fenders your set... great job once again.
Great job!! Seems like it runs great!
The heatgun-faded plastic trick was a new one for me. I'll have to add that to my repitour.
Yeah worked pretty well@
Love the videos I watch them all..the only thing I hate is how much we can hear you breathing lol idk why but it bugs me but keep up the good videos man
I've used those covers, they've always been to short for even heating and stretching. I started getting them elsewhere. Good luck Joe. 👍
And thanks for the videos I’ll be watching all of them
My god that valves seriously bent!Love ure thorough work!In ure experience for yzs kxs etc,is it OK to do a transmission, fluid,change when cold?🤔🤔🤔👊💪👍
She runs perfect dude 👍
a regular gas torch will bring that color back fast and it will look great
Little advice for you if it's ok. Next time when you're trying to get a broken bolt off like that. Get it as hot as you can, when you're done welding the nut on it should be glowing red. Then put a good pair of vise grips on and it should most likely come out.
Thats the way we do it at work for broken manifold bolts on heads and works great
When I do the nut trick, I only thread the nut onto one thread and then fill the rest with weld up to the top of the nut. That usually produces enough heat to get her free.
I just used it on my jeep. On wheel bearing bolts that I didn't have the right size socket for. I just welded a nut to the top of the bolt. Got it cherry red in the process and got them out with no problem. I'm not saying that it's a 100% guarantee. But if they're that stuck in there you'll most likely never get it out if you don't get them super hot.
You can grind a line into it aswell and drive it out with a flathead screwdriver or drill bit all types of methods
When I seen your title I answered it with a set of rings you can and maybe a little something else🤣🤣
Man good job a few Suggestions when your honeing cylenders put your drill in gear 1 and slow it down a bit and use oil that will help the stones cut better
Great lil machine.nice trail rider.b safe.peace
To get it in reverse there’s gonna be a little button by your clutch lever push that in pour the clutch lever back Then pull the reverse lever/handle up Then it will go into reverse gear but great job bringing this back to life very well job done do you still have this particular quad?? you can do so many things to this and they last a very long time
I do love the snowmobile videos
Bravo 👏 she's a little ripper!
Hey 2 vintage that problem I had on the ltr450 was cause by a aftermarket starter the shaft is a bit longer than oem I put in an oem one and it turns sweet
Oh awesome! Glad you got it fixed!
Excellent work as always Joe !!!
About the seat cover, As soon as you said 88-00 I knew it was talking about the utility TRX300
Click down on the shifter while pulling up to get it to go into reverse
I know nothing about atvs but I have a honda fourtrax 420, just had the piston rings changed on it and a few other things few weeks ago but now it's smoking after I changed the oil, damn I must've messed something up..
but I'm learning a lot watching these and hoping to fix it myself soon
Trx300 is a utility quad. What a hack! Not taking out broken bolts. To put it in reverse theres a button you push down on the clutch lever, pull the clutch in then pull the lever up. I cant believe i watched this!
Michael Sabo would not approve ! Good bike for Jade . It's still snowing up there ? Getting warm here in the south .
Just grind off the long part of the one to match the other one.,or use heat on the outside.& regular vise grips the loosen it up with.& do the other process to the other one. To get both bolts out of the engine block for mounting the jug onto the engine with.
solid advice ^^. i cringed when i seen him applying gasket maker under the base gasket..like...wtf bro ?!. bad way to seal for future oil leaks...and that gasket maker crap will throw the tolerance out of spec. he's got the '' i like working on these '' talent, but loses me when he does it half assed where you should not.
Selfishly I wanna see you do a road bike some junker from the early 2000’s 😂😂😎😎👍🏼👍🏼
You should use pb blaster on that stuck bolt and heat that will extract it pb blaster is 10/1 better than wd40.
Those reverse boxes are a pain, have fun with that.
love all videos should start posting more bikes ❤️
Thanks for watching! I posted a bike video last video. More to come!
Never hammer out of valve cut the end off 1st, heat that nut up when you weld on it till it's orange and never hone in fast and dry. I like seeing the old bikes brought back keep it up.
Hey im a huge fan I’ve watched all your videos bin subscribed for a bit now good work teaches me alot !
Thanks for watching!
Don't think nobody heard your stomach growl cuz I did. Hahah I thought it was mine hahha😂😂
Oh yes we did, should have had his weetabix.
Try getting a Bolt Buster induction heater for stuck studs like that
Good job.
Man keep that cold weather over there lol. We don't want it haha
Hi Love you viss mate it helps alots
When you are checking ring gap use the piston keep the ring square in the bore plus check the ring gap at the bottom of the bore as well as the middle, piston to wall clearence depends on the piston material one or two mill on the loose side isnt going to kill the engine
Good job man. But this thing looks so odd without those front fenders 🙈
Yeah I know
Rebuild wise I wouldn’t go cheap, you get what you pay for
Good job!!!
You had the seat cover upside down 😅still looked small but if you put in dryer for bit it stretches
Hi when you hone a cylinder you need to use oil not the stones dry you get a better finish and when you measure the ring gap push the ring in with the piston just little tip for to do a better job and better finish
Great video
the way you honed the cylinder could be considered a hate crime...but somehow, even with that garbage piston..it will probably run forever...on 87 octane....with a generic air filter...and bent valves...because why wouldnt it......ffs....
lol! yep
It’s because he’s not a try hard
Why would it be considered a hate crime?
Treat your cylinder like a woman. Can’t just stick it in dry you gotta give her some lubrication and longer strokes
@@Jetsonn scratches should be at a 45 degree angle. To achieve that you need to run the drill at a slower rpm and move up and down faster. And you shouldn’t have it tilted sideways and hone it, you’ll get more pressure downwards honing it that way. And be more consistent with the up and down movement
@2vintage i got a seat cover same brand for my warrior, you have to leave it in the sun to form its shape
Did you really hone that cylinder dry? That's a no no if you did.
Was gunna say the same thing but was reading comments to make sure no one else had said it...there's always 35 comments about the same thing lol
He still gets it done everytime pretty much
@@camdencrotwell349 lol yea, funny how that works out. Because according to the know it all's in comments all of his builds show implode instantly.
you dont see the oil coming out of the cylinder after hes done honing? he literally wipes the oil out the cylinder out with a rag in the vid. everyones so quick to rip on him but cant seem to open there eyes 🤦🏻♂️
U put a bIg exhaust on it and it will run like a champ I had a stock 300ex before after I changed the exhaust it ride better and sounds good
So weird man, i keeep tellin ya we are cosmicly connected, working on the same quad now as usual!
Haha weird!
you should heat it up with a blow torch first the try and remove the snapped stud or bolt
They sell a kit to renew plastics on ATV s in all colors. My buddy used it on a machine came back to like new
Dudes starving 😂😂2:40
For that faded plastic just use torch it will bring it back like new
Shift to neutral push red "R" on clutch pull up on reverse lever , and your off it's easy
That seat cover was for the utility Honda 300
FYI supposed to use some kind of cutting oil when using a hone on cylinder or oil.
We’re did you get your rebuild kits because I have 5 300exs and one of them is blown and can’t find a good quality one anywhere
My wrist pin is stuck it seized to the pin i put heat tried to hammer it slightly and now am drilling it saw where someone sawed the piston what would you do? It moves on the shaft but its stuck to the piston so i figured if i drilled it with a universal bit and it got cut away from the piston i could pick it up and off and pull the pin. How much play is allowed in the drive shaft bearing ?As of now it moves about 002 of a filler gage at most.
Invest in a glass bead machine, work bench model or floor model and parts washer, then you could really clean all ur parts up real nice dude..
My 300 has the same exact problem hopefully it won’t now since the whole top end just got rebuilt
theres a button on the clutch cable u have to push down then pull the clutch in and pull the reverse lever up.
I'm a 30yr.motorcycle mechanic.I get it,I've used Niche parts ( cheap chinesium) but there is a reason the Wiseco was $140 and the Chinese CAST piston was $30.Just as anything in life you get what you pay for.
How long did the Niche piston last in your application vs the Wiseco?
Nice
Can you tell me where to get the key fab plastic for the key switch? My 94 has the big handlebar contraption. Thank you
Hey so if y’all have headphones on at 2:41 turn up the Volume you can hear this dudes stomach talking 🤣🤣🤣🤣🤣
Do you have a video on how to set timing ?
Does the cylinder head nuts and bolts have 10 mm washers that go with them or no
May should have added some heat to the area with the broken bolts and that might woul have helped getting the broken bolts out.
Is the valve bent from hitting it to get it out.
Reverse go in netraul and theres a button on the cluthc push it down then pull the clutch in and pull up the rod then youll be in reverse
