  • I end up going through my 1999 Honda 400ex to see why it is smoking. These quads are known to smoke, and fining one that doesn't is pretty rare. #SmokeyGirl, #Honda, #400cc,

      Oil rings could be buggered or or it could have a lot of oils built up in the the exhaust i had one and it had same problem which was just the exhaust best of take the tip off and put the rest in a hot Fier and it will clear it all out

      It’s definitely more put toward valve seals but the oil ring could be going bad but it isn’t the worst because my 400ex has a bad oil ring and it won’t even run half decent because the thing runs with oil in the gas due to a bad oil ring.

    • @roryk.3568
      @roryk.3568 Před 2 lety

      More than not a bad valve guide will smoke on startup and clear out as it warms up with an occasional puff of smoke. My bet is rings as well, gets progressively worse as it warms up.

    I can’t believe changing the oil and cleaning the carb fixed the smoking. I was guessing it needs to be honed and new file fit ring set at the least.

  • @jeredalmeida1880
    @jeredalmeida1880 Před 4 lety +5

    It's the oil ring but might as well replace the whole ring set. For someone who flips so many older bikes, I don't think I've ever seen you hone ONE cylinder. That little bit (bit) goes a long way. What's happening is there is wear on the rings or possibly the cylinder wall. On the down strokes, the oil is making it's way into the combustion area above the piston and igniting. Hence the smoke. Just like in a 2 stroke, your burning lesser refined petrol. Since a four stroke has such high compression, it's still running but if this were a two stroke, that little bit of blow-by would cause stalling or failure. It could also be valve seals or the valves themselves as oil could be making it's way into the combustion chamber from above.

    Its actually a pretty common problem with these quads, a lot of the old ones that you find around normally smoke. As other people have already said its the valve seals. My suzuki 230 somtimes burns a little oil when its started after sitting for a while.

    These quads are notorious for valve seals I’ve changed them more times than I’d like to count here at my shop. I wouldn’t waste your time with cleaning the carburetor and I wouldn’t give it an oil change until after you change the valve seals and have the motor apart.

    I've unstuck rings with some atf down the spark plug hole on an old atc 200x. I honestly think that's what wrong. If it were the valve seals you would only see smoke on startup after sitting.

  • @thomasmarshall5728

    Your not supposed to twist the dip stick in when checking the oil level. Just push it in until it stops on the threads. So you probably have less oil than you actually think

  • @joemumma5058
    @joemumma5058 Před 4 lety +4

    It's not valve seals as the smoke would clear after a short run time but the smoke is pretty consistent. Try dropping the viscosity of the oil and replacing oil rings. A four strokes oil rings can blow while the compression rings are still good and the bike runs great. So a thicker oil synthetic oil, and new rings.

      you are correct. after you take it out you wipe it off and then place it back in all the way do not thread it back in. Just stick it in and back out and thats the oil level. However the jug makes it pretty forgiving. If you are doing it from the crank case that oil would need to be perfect.

    If it is valve seals they are not super hard to do but like you said you might as well do rings since its a couple of more bolts to make sure the motor feels good and do break it in those gaskets on the head really to need time to set in my buddies blew his valve cover gasket directly after rebuilding the whole motor because he decided to tp rip on it for like 10 15 minutes during break in

    @ronniewilliz153 Před 4 lety +24

    Nothing but a new oil ring is gonna fix the dam smoking. Maybe just maybe the vales are not seated right. But i like how optimistic you are it not needing to be rebuilt tho. I do the same ill try everything else before i break down a fix the problem u gotta try atleast. An have u started learning how to properly tune things. I know ive said it in the past but you'll get alot more performance out of any bike if you know how to tune. An pls dont use a flat head to gwt the 2 cases apart you will dent it an it will not seal right yes im sure you where carful an what not but so was I when i use to do that untill u put a hairline gash in a case once an had to double up on gaskets. An yes i did sand it down to get a flat surface so it sealded again but use a dead blow hammer or tap on the case to get 1 to fall off.

    Start with a set of rings , it can have good compression an the oil still get passed the oil ring , way easier job then to try an do valve seals first , i wouldnt run it like that youll hurt something more in the long run , if its burning that much oil its not valve seals
