I don't even have an ATV and I just watched this whole video! I love learning and this guy is freakin awesome. Definitely makes me not nervous to do this job myself now.
Yeah, but he left out the stuff that takes the most time; Plastics and gas tank. He also didn't check ring gaps or measure piston/ cylinder wall clearances.
Well explained! About to be doing this myself to my 2017 with 150 miles on it after I sunk it and turned it into a fog machine then let it sit because I have a "CAN'T AM" but ready to get it back up.
A woman who can sit and watch you rebuild a motor is a good woman. A woman who can sit quietly and watch you rebuild a motor is a great woman. Never let her go.
We did this on the trail 2 years ago. Buddy cracked a piston in his rubi and we couldn't pull him 20k thru the mud and up shale covered hills. We ran to Honda picked up a gasket set and ordered a niche 10-1 piston off amazon. Took us about 3 hrs to get done with limited supplies it ran better than new afterwards. Bike sat in the woods for 3 days before we had the parts together.
Question, when I put the valve cover on, it didn’t sit on there “nicely” I’m thinking one of the four studs backed it’s way out a little and is hitting the rocker.
I would never go to all the work of rebuilding a top end without checking ring gaps and piston/cylinder wall clearance. 10 minutes checking that shit could save you hours of doing it all over again. Also, rags are good to use, not just talk about. You just about had one of those dowel pins drop in the bottom. You were damn lucky.
Thanks for all your opinions lol when you install a new OEM jug with OEM rings and an OEM piston eyeballing the rings is good enough I've done dozens way more than you I'm sure
@@MudPuppyOffroad Typical answer from Christian the arrogant prick. You really are full of yourself aren't you? Honda can have a fuck up just as easy as anybody else. Also, they don't make their rings. Somebody else does. They can be out of spec. So why not check them? Takes 10 minutes.
@@MudPuppyOffroad Yeah, if you don't count taking all the plastic off and the gas tank and the exhaust. Since you can't do a top end without removing that shit, it gets added into the total time.
I do check rings whenever building something with tight tolerances that it matters like my 450 for instance. Even then it doesn't take me 10 minutes more like 30 seconds... but then again I'm a genius so I understand why it takes you so long
Got a question, first off love your videos…in this video every thing was described perfectly. However after rebuild new oil and coolant…after 30 min of. Riding the atv started over heating…seems my reservoir is filling up but not returning to radiator. Water pump? Clogged return?? Not sure.
It could just be air trapped in the system. these ATVs usually bleed themselves but you can check by removing the hose on the top of the thermostat housing and see if you get any air pushed out
I torqued everything down right , why is coolant leaking out my head gasket and ig getting in the cylinder and making it smoke any idea ? Yes the coolant is getting in the oil
This may sound like a stupid question but how do you know if you're getting low compression and is it a very noticeable loss in power and other than loss of power are there any other signs??
@@MudPuppyOffroad what’s your reason for not really ever getting into the Polaris world? I know you have owned a few I believe but you usually stick with Honda’s.
@@MudPuppyOffroad thanks , I was on my 06 Foreman 500 going up a small hill on the Hatfield and McCoy trail here WV on Wednesday at the end if our ride it started losing power and it was making a noise in the top end then it finally died . I think it dropped a valve haven't had time to check yet .
Well the main thing that will get water in the oil is the crankcase vent, so make sure it’s ran into your airbox, also look up crankcase breather mod, it’s by project ajax on RU-vid
So did you ever find out if the oem 520 cylinder fits the 2017? Ive got the 500fm1 foot shift straight axle And would like to do the top end also does the new head differ from the 2017?
Would you be interested in helping me or showing me how to rebuild my 2014 Rancher need a full motor rebuild I’m buying the parts I’m 14 and looking to learn??
When I put my top end on, I messed up by putting the piston on the crank before the jug... and that was the biggest pain in the ass I’ve ever experienced
@@MudPuppyOffroad Yamaha seems to have one of the best belt set-ups. I agree though that they seem geared a little high for big tires. I see a Brute Force in some of your videos. How are they sealed up for the deep stuff?
Yes those are an extremely brutal tire They are hard and might as well be square They will break all kinds of stuff and are hard to turn They do pull amazing in clay though
I don’t stand as Advanced Honda/Acura engines are with there VTEC and J series V6 SOHC engines. Why still use OHV push rod engines. On there Powersports. Use SOHC engines like how Yamaha does.
