I just got this quad a few days ago and finally got it running. It has oil leaking and it seems to be coming out around a cylinder bolt. Not the valve cover but just below and to the rear. Is there supposed to be crush washers on that bolt? and what are those bolts supposed to be torqued at?

Thanks

Thanks for the welcome. The bolt i am referring to is just below the valve cover and I think it is one of the bolts for the cylinder head. It has a domed head

Maybe someone in the past tried to stop the leak with a crush washer, who knows.

I am an older guy just learning to use computer stuff and I don't have a camera to take a picture and if I did I wouldn't know how to get it from a camera to the computer box.

Have you tried to tighten the bolt down? Maybe loosen it up and put some high heat silicone on it and re tighten.  

Do the other bolts have the same washer ?

Might as well check all of them while your at it.

I do have some high temp silicone I can try. I was kind of worried about over tightening and breaking something. Do you know if there is a torque spec for this?

Thanks

I’ve done it in 2 hours not by choice and it worked great. 

Honestly... I would wait 24. 

Also remember to clean the area with a little carb cleaner to make sure all the oil away from the area.  Just a little shot will do.  Dry it with a rag.

another thing to remember is if you take a bolt out, especially those long ones that hold the head and cylinder to the crank case, never put the bolt back in if any liquid gets in the hole-  let is sit overnight and air dry out.  Have a relative that does automotive repair and she has cracked crankcases before because she torqued down a bolt that had water (or some other liquid) under it.  That water is very powerful under pressure like that, hence it cracked the case and ruined the engine.

      I Was Riding By Myself. I was going through a Mud HOLE Either there was a log or a rock, or A Dip but just as I was almost through it, Machine, Rolled over on my right side, as soon as I contacted the ground, I Heard A SNAP! I got up, flipped the Quad back over. I had the wind knocked out of me.

      Hello All
      I'm kinda new to ATVs. I just bought a 1987 Suzuki quad runner 230 Dual Range. I'm having a problem finding info on it. It's very clean, only 2.800 miles. The front wheels are only 30 in.center to center. I was thinking about adding wheel spacers to give it more stability. I realize the added stress on ball joints and bearings. I'm wondering if there are any other concerns? Any input is greatly appreciated!

      I hadn't driven my Kodiak for a two months, and since it was low on fuel, the first thing I did was filled it up to maybe 7/8 full. Getting ready to start it, I rotated the fuel selector switch to "on" and within seconds I smelled and saw fuel dripping onto the floor. I quickly turned it off and the fuel gradually stopped - I can repeat this.
      The fuel is flowing from the hose that is connected to the bottom of the carb, and routes around to the left side toward the wheel well. Any idea what's going on here? It ran fine the last time I had it out.
      Thanks...

      If anyone is having issues with the Mikuni VM24SS carb, I thought I would post what issues I had and how I resolved them.
      Acquired a 93 Bayou 220 that had sat for over 4 years.
      The carb was extremely corroded and pitted and full of leftover fuel.
      Cleaned carb and bowl and was able to get the engine to start.
      Within 30 seconds exhaust would heat up and start to glow red hot.
      Removed carb and recleaned everything, including a second overnight soak.
      Needless to say, after removing the carb for the 5th time and my frustration to the limit I
      realized that my attention had been to the carb body and not to the bowl.
      There is a small brass rod on the bottom of the carb that goes down into the float bowl but is seperated from the main section. I had cleaned that area very well....I had thought.
      ***The corrosion had sealed off the channel that runs from the main bowl section to the small tube section on the side of the float bowl. No amount of carb cleaner was going to get it to budge. So i took a small nail and started to scrape away the corrosion and was eventually able to dislodge enought of the corrosion that carb cleaner would flow through that channel. ***
      I thoroughly cleaned each side of the channel in the float bowl and reinstalled the carb and now the issue of it running lean is gone.
      On a second note the fuel mixture screw was a nightmare to remove as the threads had been corroded and wouldnt let the screw come out. I used a little cutting oil and worked the mixture screw in and out until I was able to push past the corroded threads and completely remove the needle. After a couple passes with a tap to clean the threads it is like new again.
      Hope this helps if you are having a lean running machine.
