11 posts in this topic

Hey everyone I just bought a 2000 Honda foreman and it smokes a lil and sometimes oil comes out of the muffler but the guy I bought it from said it needs carb work cause it sat for two years he said there is a lot of sea foam and fuel stabilizer that he put in it that's why I think it smokes it anyone got any ideas it runs but bogs out when you give it gas but fires right up some one please help me!!!

The first thing do is change all the fluids and filters, put fresh gas and a fresh plug in it and check the vavles. If it still runs poorly after that, I would move to cleaning the carb. Take it off the quad, take it comletely apart and clean everything, all holes and passages, make sure not to lose anything, there are some small parts in there. Keep an eye out for damaged gaskets and seals. If you still have problems after cleaning the carb, then do a compression test. Please keep us posted on any developments and feel fee to ask as many questions as you want. I would also recommend getting a service manual, they are well worth the money.

Ah yes, mechanic in a can, that'll fix it!

Change all fluids, should be OK. Hondas are hard to hurt.

Mechanic in a can, I like that. I am a big fan of seafoam, but too much of a good thing, isn't a good thing.

To check the vavle lash, first set your motor at TDC on the compression stroke. If you can't find the timing mark on the flywheel, then just remove the valve cover on the top of the head then rotate the motor until the intake vavle opens and then closes, stop it before the exhuast valve begins to open. The idea is not to have any pressure on the valve train from the cam lobes. Next, you slide a feeler guage between the top of the vavle stem and the adjuster nut that pushes the valve. I believe the gap should be .006", but I am not sure, you may want to call a dealer tech and see if they will tell you what the clearances are. If they need to be adjusted, there is a jam nut at the top of the rocker arm, right above the vavle that holds the adjuster screw in place. Loosen the jam nut and screw the adjuster up or down until you have reached the specified gap measurement. Then, carefully tighten the jam nut while making sure to hold the adjuster screw still as not to change the gap. I would recommend getting a repair manual, all of this info will be in there, as well as torque specs and other valuable info that you will most likely need at some point.

Hey I posted a forum about this ATv earlier and I did exactly what y'all said all fluids and filters changed everything but still smokes bad and makes a knocking noise in the top of the motor.....any suggestions?

sounds like maybe your valve stem seals are shot... pop the covers off and adjust your valves for the noise and look at your stem seals closely... you may find the culprits there.

I merged your two threads together, no need to post another thread for the same issue. You want all the info in one place, it makes it easier for people to get an idea of what exactly is wrong if they can read the whole discussion.

Did you check the vavles or do a compression test as I suggested before? The smoking could be bad valve stem seals like Raptor8 said, or you could have worn piston/rings. Also, as Raptor8 mentioned, the noise coming from the top end is probably your vavles needing to be adjusted. The only way you are going to know for sure though is to take a look under the cover. Good luck.

      I bought a Honda 250sx 1986 but the exhaust is broken. Apparently it's not possible to order a new one. I checked to order one on others compagny but there's noting.
      Do you know which exhaust it's possible to install. Is there a company who sold an exaust to fit on my 250sx.
      Sorry for my english
      Thank you

      Im working on a old 1987 honda 125 4 wheeler in the school shop. It will start by getting pulled by another 4 wheeler but wont start with the pull start or Electric Start. When you pull start it it tries to start but when you try the electric start it just turns over but doesnt even act like it wants to start. The spark plug is dry and it shoots fuel out of the back(air filter side) of the carb. Weve had the carb off twice and it is complety clean. What are some things we can try?

      Hey I own stock why Yfz 450 and I'm just looking to slap a turbocharger on it.. I was just wondering if they're pretty compatible with these machines it is the carburetored version Yfz 450. I have all the piping hook ups / kit that's threw HURON SPEED an i also have turbo lined up for it gt 12.. I was just wondering what else I need to make this work? I know i would need to up the Jets and stuff for starter but Is it just that simple or do I need blow off valves and like some time on regulator on it or so forth? Trying get ideal what i would need
