    Well I’ve seen some say that Shindy makes the OEM Honda pistons but don’t know if there’s any truth to it.

     

    They are less expensive than OEM and work perfectly

    That's good to know! I can't seem to find much of anything really for parts I guess the 400fa isn't common 🤷

    Check the small end of your rod with the wrist pin and make sure there is no play there.

     

    I use Shindy pistons.  They come with rings, wrist pin and circlips.  Made in Japan

    Thanks for tip I will have to check that. What would be genuine Honda parts be ? Shindy pistons?

    So I got some prices from Honda for piston it's 110 for standard or oversized, rings are more money for oversized though... Crank is alot hopefully mine is ok.. I removed piston and connecting rod looks straight but it is blue and so is crank is this ok? There is a little side play but no play up and down tight. Piston is beat 🤣. Iam still breaking everything down just need to read and watch more vids before I get ahead of myself. Currently searching for used head... Anyone got one? Valves and spring are very cheap I was happy on that price

    So tore into her today and she dropped a exh valve... Heads has alot of damage I believe she'll need to be replaced.piston has a hole through it.. cylinder has some small nicks not to deep not sure if I can save it. With the hole through the piston I decided to take motor out to go through to check everything and clean.

    Holy crap I can't believe a 400 Rancher held up that long if you were working it like that! 

     

    The 400's with the Hondamatics were known for having problems if worked hard or modded for big heavy wheels and tires.  They tended to burn up clutches if modified in any way or worked hard, especially if ridden in auto mode a lot.

     

    But it was usually Hondamatic/clutch issues.  What you have seems to be top end/oil starvation issue.

    Ya iam thinking the oil wasn't gettin to the top perhaps oil pump failure.. the more i think about it... She's probably gonna have to be split and inspected.. check pump ect.. I will have to print manual out start reading up on the old girl... If I get a chance I will post pics of hours and kms

    Did you notice if engine was very hot when it quit? distorted plastic or other heat damage? Smoking from engine surfaces?

    Never noticed excessive heat but these are some facts lol quad was a old cn railway unit it's has 20thous km.. it seemed underpowered like 45km max speed.fan was rigged to come on when switch is on ie key.. yes it's a toggle switch 🤣 the oil light was on but had oil ... And just before she went, limp mode kicked on speed dropped to 15km then boom after about 5 min trying to get back to shore..

    Nothing is cheap anymore, but Honda parts are less expensive than most brands.  Rocky Mountain ATV or Honda East Toledo seem to be the cheapest.

     

    You can also look at used OEM parts from places like Powersportsnation depending on what you need.

     

    If your crank is bad, Vince at Mr Crankshaft and rebuild your old crank for 1/2 to a 1/3 of what a new OEM crank costs.  He uses good Japanese Vesrah connecting rods.

     

     

    Appreciate all the info 🤞on crank lol. I do know one thing nothin but OEM parts on my stuff especially internals there's a reason it runs forever... Honda.

    Sounds like you know the lower end importance , if the crank is loose , the upper rebuild won't last long , if it has been sunk ,   or  ,  if the piston is damaged and lets  fragents go into the case , then it should be split and cleaned out or it won't last long as long as it could have , if done right 

    I do know if ! gets past rings then iam into it lol. I have only rebuilt one motor and it was a old Onan motor. but the Honda shouldn't be to crazy from the opposed Onan.. hopefully Honda parts are cheaper lol than Onan parts...

    No easy fix there. May as well remove the cylinder head. Plug looks overheated. Insulator core is missing and conductor misshaped. Could have happened by impact  too

    Hopefully next couple days get head off I just hope bottom end is ok..

    Pull valve cover and inspect valve condition. Maybe dropped a valve. Don’t try to roll it over anymore til you see all valves are in place

    So I got Time during cooking burgs on the barbie. I ripped all plastics,tank off then tore top valve cover off...so something dynamited lol I grabbed onto valves and  springs I couldn't get them out by hand so not sure if they broke...but not ruled out yet I gotta take head off still.. here's the pics of the spark plug that is gone lol. lookin in spark plug hole its alot of aluminium shavings so not great

    I would start with removing the rope starter and try to move the crankshaft with the bolt. A little back and forth to see if whatever happened will come loose. Any weird noises before the "pop"?

    No weird noises just was in limp mode then just a pop and a clank . everything just stopped instantly I was going about 15km hr. The quad was working great all day but on my way in I noticed esp limp mode was on then she was a tow in..

    Had the 07 Honda 400 out ice fishing on way in I noticed it was in limp mode I had 2km to go so brought her in slow. Was running good then all sudden a pop from front and she stopped instantly shutting off no start and can't pull her over stuck.. rolls in neutral easy I can select all gears but I believe she's toast.. guessing the crank broke anybody have any thoughts. She has oil I haven't read the limp mode code it was raining and cold fishin sucked aswell..

    Was given a half disassembled 07 Honda rancher 400cc, just about have it back together but iam struggling on the simplest thing. not sure if missing parts or its me 😂. Can't figure the proper position of the oem air intake pipe, and no I don't want a snorkel. Just want to arrange it the proper way. Note I know the way it is now is wrong I just did my best
