1995 scrambler 4x4 issues

Recommended Posts

I have a 1995 scrambler and when i ride it for awhile it will start to smoke like crazy. This is what i have checked. The gas had some water in it when i drained it put new gas in it ran great for a while then i got on it pretty good and it looked like a cloud of smoke coming out anyone have i idea what my problem is?

If it is black smoke it is getting to much fuel. If it is blue smoke it is burning to much oil. if it is blue then you might want to check the oil injection system. The oil injection system my need set and cleaned. If it were valves you would have problems right from start up and it would run like crap. I would suspect that it is getting to much oil.

There are no valves, it is a two stroke. Check the air cleaner, make sure it is clean. A dirty air cleaner will cause a rich condition. You could also have a problem with oil getting into the crankcase. That is usually either a bad crank seal or a leak between the case halves that lets the oil into the crankcase from the counterballancer chamber. Another possibility is that the oil injection system is putting too much oil into the fuel. Are you mixing your fuel too, unless you have an oil injection block off, there is no need to mix the fuel in that thing, just make sure there is 2-stroke oil in the tank. Another problem could be your head gasket or a cracked cylinder or head that is leaking coolant into the combustion chamber. You need to figure out what is causing the smoke, like Gearhead said, black smoke usually indicates a lean condition, blue smoke is usually burning oil, and white smoke usually means you are burning water or coolant. Antifreeze also has a kind of sweet odor when it is burning.

But the only time it really smokes alot is when i am getting on it pretty good. Does not smoke bad at slower speeds. I have also checked the coolant and it is full so don't think it is the coolant.

Agreed, the first thing we need to know is what is causing the smoke. Is the smoke black, blue or white? Did you read my last post? Did you check any of the simple things like the air cleaner? What about the fuel? Are you mixing your gas? If so, you are going to get too much 2-stroke oil in the fuel because it is oil injected. I suggest these things so you can either confirm that they could be a problem or rule them out so we can get some info on what is going on.

      Happy New Year all! Remember not to operate any vehicles while under the influence, you could get busted or worse, you could get hurt or hurt someone else who's playing it safe and end up in jail. Have fun and be safe.

      So I’ve had this quad for the better part of a month, and it’s been hard to start since the day I bought it. Once it warms up it idles just fine and has plenty of power and starts no problem, but cold it takes 20 seconds minimum of straight cranking to start it.
      It’s not really too big of an issue, I’m just curious as to why it takes so long. Earlier today, it took me about 2 minutes of on/off cranking to get it to fire.
      i have attached a video of a cold start to show you what I mean.

      Hi Everyone
      This is my first post and I was wondering if there is anyone who can help me solve a problem I have with my Yamaha Kodiak 400 4x4 Fitted with a Mikuni Carburetor . The year of the quad is around 1998, the reason I am not sure of the date is, there wasn't any paperwork and no details on the frame either.
      The quad had a bad leak from the carb overflow which indicated that the float needle valve was blocked or passing so I replaced this and put everything back together. The quad ran really well until I took it onto some rough ground to have a ride around, a few hours later the engine started to run really rough as if the engine was flooding. I have removed the carb again and cleaned the needle valve out and the whole of the carb just in case there where any dirt behind it. Engine now runs fine again but fuel has started to run out the carb overflow again.
      I have tried everything to try and stop the fuel leaking out the overflow but its still happening. My last thoughts where to adjust the float level and its still happening.
      Has anyone got any thoughts on the problem or could suggest whats causing the fuel leaking out the overflow.
      Thanks for reading
      Kevin

      Hello, well back to where I was last year with this carb. Took my 250 to the mountains for the first time this year and blue smoke, too much gas again. I can't believe that this carb gives me this much trouble. Seems like the choke is stuck but the cable moves freely. Anyone else ever experience this issue? Do you think a new choke cable would maybe resolve this?http://www.quadcrazy.com/atvforum/images/smilies/arghh.gif
      OK it was the choke. Put on all new cable and plunger and she is running 100% again. So now the question is, is the carb getting worn out where the plunger needle goes in the small hole and when I use the choke the needle end doesn't get lined back up with the hole?? We'll see how it runs and now that I know what the issue is I can always pull the choke plunger out and reinstall if I start having this issue again.
