I had an old 86 honda fourtrax 2wheel drive that was in worse shape bodywise and put a new Wisco piston and rings in it. If you got it all apart like that, $160 for a piston is totally worth it especially with everything else tight in the engine. That mistake will haunt you
For as bad as it was it's running pretty good 👍. Some hunter will buy it. Give it a shake down ride and maybe it'll stop smoking so bad. Thanks again for your time today and have yourself a great week.
I've always wondered why you don't clean the bikes before you take them apart? Seems like a lot of crud can drop into the engine when you're handling the tear down.
You need to get the plastic welder from harbor fright the one that you hook to the air compressor and order both filler plastic rods HDPE and LDPE and show how you fix all your broken plastics. its easy and practice on a 5 gallon bucket. really like your videos
You definitely amaze me with your analytical troubleshooting skill! What you generally think is wrong, usually is. Good too see you could save her, to a certain point, great video, as usual! All of your videos are so interesting to watch, you do a very deliberate, step by step walk through, and you only go as far as your knowledge let's you, meaning you know when too call it quits. I was a two wheel motorcycle person, in my younger days. Wish I would have dabbled more in depth with 2, and 4 cycle diy repair. Great video, as usual. Thanks for sharing.
Great to see the skills you have developed while repairing these. MMI, will give you basics but to me you've got all that, keep hammering away.. great job.
Good video. As far as the timing off, the timing was way off because you had the piston at top dead center exhaust stroke. Both lobes were in valve overlap, that's why it looked way off. You just had to turn the crank 180 degrees, and now it would have been in TDC compression stroke.
If you make it a point to open the throttle to take a compression test, what are you accomplishing if the cam isn't operating the valves? (No rocker arms installed)
I can hear as your driving it hard, the choke is staying on a tiny bit. If you can smell even a hint of fuel in the exhaust that’s likely why your seeing the blue smoke. It’s a fuel enriched I believe and on this model the spring gets weak and when you slide the choke lever to off, the weak spring won’t fully return the valve.
@@kittenfat2207 Not a chance. The plastic is High density polyethylene. It won't dissolve that's why it is so hard to repair. The old way was plastic welding. I think 3M now has some adhesives that will bond it.
Joe, love your channel and am always looking foward to new projects and you never disappoint. I have seen you bring back worse this this. Like the mule..lol this quad isn't that bad. Should have taken the paint off. I think you would have been surprised.
Nice video. Why was the area around the head smoking after startup? I've noticed this in a few other videos and wondered why it is not just coming out of the exhaust.
Love the vids keep up the great work. Just a quick question. I have a ttr225 which is a 70mm bore. Weisco doesn’t make a specific piston for it but would just s normal 70mm four stroke piston work for it if it’s just a universal piston?
Just FYI you should never hone a cylinder if you’re not going to replace the rings. They wear to seat and once seated to the cylinder they will not seat to a fresh crosshatch. And as one guy said in your comments.... if you’re honing you need to wash the cylinder really good with soap and water then wash with brake cleaner followed by some oil to keep it from flash rusting. Great to see it run again.... great job. Oh PS.... when engines have a slight miss to them and cleaning the carburetor does nothing to help it don’t rule out oil getting into the combustion chamber and interfering with the air fuel mixture due to really bad piston rings or scratched cylinder walls.
Over the years I've bought rebuilt bikes where wrist pin clips fall out and the wrist pin wears a groove in the cylinder.When replacing pistons,do you replace the clips with new ones?
Hey man you do a great job on quads and bikes. I have a Honda 250ex (2001) that smokes like a freight train and was wondering if you would be up for rebuilding the top end. Not sure where in WI you are located though, South Central?
I purchased a 1999 KX250 from a sheriff that got it at their police auction. Spent over 800 fixing the bike up and rebuilding the engine. Had the bike listed for sale and was going to make a good profit from it being it looked better than it did from the factory. When I listed it I had a lot of interest in the 1st day. One person begged me to hold it. They even sent me 100 bucks to hold it and said I could keep it, even if they did not show or decided not to buy it. I said sure. They showed up 2 days later with paperwork. They showed me the paperwork and I verified it was the same bike and same Vin #. Now could of fought it legally? Probably yes but at what expense? I felt bad but at the same time had a lot of money into the bike. Good thing they offered me what I had spent on the bike and parts. I gladly accepted and they got back a nice bike. They should me pictures of it they took a couple weeks before it was stolen and it was in good shape. How it made it through a police auction baffles me till this day and worries me. If reported stolen dirtbike that a police report was filed on in the same state a police auction sold it makes me wonder how many more stolen dirtbikes and ATV's are sold in police auctions that are reported stolen. Only 8 months had passed. Not like it was years
Good job joe look on the bright side it didn't blow up lol not a bad job at all mate somebody will buy it for sure if you decide to sell take care man 🔧🔧🔧👍👌
I know you gotta draw the line somewhere but unfortunately it still has low compression because it needs rings.. a good running engine by itself is worth a nice chunk of change if you parted it out
Good idea to lap in all the valves while you have it apart . Use s piece of rubber fuel hose on end of valve and a drill . Use valve lapping compound till the valve and seats are shiny.
I would like to see an upd8 for the one that was turning off. When I first heard it Sounded like it wasn't getting enough air and / or, fuel Though , it's better to always check out the electric system infrastructure so it might be better to replace the spark plug with an NGK . Usually the better ones
24:31 Man you need to slow down your speed on the drill. You are trying to get a 45 degree cross hatch in the bore. At the speed you are spinning that sucker you are just making radial scratches in the bore. When the hone makes half a rotation you should have pushed it from the top of the bore to the bottom, and in the second half of a rotation you should be coming back up from the bottom to the top of the bore. So much faster plunge in and out, with a much slower rotation.
@@DJBigDawg420 Yup, I worked for a hydraulics manufacturer for 20 years. We had our own honing department and it would surprise most people how slow the RPM's a hone should be spun at to get a proper honed finish. And man does that dark black honing oil stink...it is difficult trying to get the smell out of your clothes.
"Can't believe it's working." I can. It's a Honda. Somewhere there is a farm that can use a four wheeler for light work around the yard. Even thought it's a "beater" it still has some value, and it's better off running than left in a scrap yard. Great job.
I have a four wheeler i bought from a friend and it was orginally a cable choke and he put on a new carb that is a electric choke is there any way i can wire the connecter into the harness is so then where?? Im new to working on four wheeler this is my first one
to bad I don't live closer id like some help on my 86 250 fourtrax not neighborhood friendly as it's louder than most. but fixing it is out of my comfort zone with motor work it starts and ride amazing but cam chain is loose and need new valve seals and gaskets
Hey just see if your interested in 2008 polaris sportsman 500 with brand new plow exactly 1002 miles has the camo skin upgraded racks and winch. Problem is front transfer case is absolutely no good and has been sitting for around 5 years. Title , papers and special order receipt from the factory..
People like to paint things and make them their own. So no it isn't "very very strange" for it to be painted. People used to paint these things camo all the time, especially the older units
Just a thought... You maybe could list an asking price in the description for the vehicles that you are going to sell.. That way we all can get in on the action instead of just people local to your area.. HAHA..
Your attention to detail is spot on, I am continuously learning new ways at diagnosing issues, keep up the hard work and keep the videos coming……question do you ever offer up for sale some of your past repaired bikes or 4 wheelers??
Judging by how much gasket maker tharpt was on the motor when you took the the cylinder someone was in that motor and didn't make sure they did it right. That chain was not loose enough to jump a tooth or two. Somewhere someone took it apart and didn't know what they were doing.
I personally think you should have gotten the piston. But I know it had a ton of other problems. Tough one. Once you throw any amount of $ into it. You might as well do it right. Maybe something for another day? It's never too late. It's mostly your time that costs the most. Or do nothing to begin with and use it for parts. That one might have been a good parts candidate from the beginning.
That idle sounds to me like it's running rich. Take a second look ak the carb that the needle seats properly and adjust to factory specs. That could also explain the smoking as the unburnt fuel mixes with oil and burns in the exhaust.
And that miss and rough idle is that broken choke drill a very small hole in the middle of the choke end and use a wood screw and screw it into it and it should break free and come out I’ve had to do that method a few times on old Hondas it works 99% of the time a 350x carb will work also it will just have a hand choke on the carb like a 400ex and you can pick up a aftermarket 450x carb on eBay for about 60 bucks
you dont just wipe the bore with a rag, use hot water and soap, spay wd of pb ,as for valves hand lap all the seats, any play with the valves at full lift needs to be checked and new oil seals, as for the stuck top ring, make sure the groove is clean and the top ring can rotate with out hanging up, if in doubt just buy a new piston and rod pin .Most single rod engines use a roller bearing on the crank (Suzuki) side play is a hair, but if the rod has angle wobble that you can feel its time for new roller bearings, which means you split the crank install the roller bearing and press the crank halfs back together, its a pain to do, the first time.
painted black dont mean its stolen at all.some people just paint there stuff thats all.dont read a lot into it being stolen,im sure your fine.just a old atv!!
It'll make a fine hunting-trapping-fishing-camping-overall work horse quad, one that can get-r-dun without worring about dingin her up. She's already dinged up, I will call her Dinger.
For $250 you could’ve fixed it right with new piston,rings,valve,seals,chain. Why go thru all that and put old rings back in it? Now take it back apart fix it right.....
!!!check the small end rod / piston pin . Is the pin rocking in the rod at all ? My 650l was misdiagnosed by a Honda dealer ( I think they straight up lied ) 6k after full rebuild I have a dead motor and only certified mechanics supposedly worked on my L .

I was wondering that too.. the valves won't open obviously.
their all supposed to be closed on compression stroke anyway, removing the rocker arms just closes all the valves.
@@atothez1931 Right but they can't take in any air to compress.
@@austinreed7532 your absolutely right, didnt think about that, has to be able to pull air in, in order to compress it.

I’ll bring it to you from Canada
you dont just wipe the bore with a rag, use hot water and soap, spay wd of pb ,as for valves hand lap all the seats, any play with the valves at full lift needs to be checked and new oil seals, as for the stuck top ring, make sure the groove is clean and the top ring can rotate with out hanging up, if in doubt just buy a new piston and rod pin .Most single rod engines use a roller bearing on the crank (Suzuki) side play is a hair, but if the rod has angle wobble that you can feel its time for new roller bearings, which means you split the crank install the roller bearing and press the crank halfs back together, its a pain to do, the first time.
You need the rockers on to check compression. The engine needs to be able to breath
