Hey guys im a new member here, names chris and I just paid out the as* to fix my big bear 350. It got rings valve seals a rocker arm a head gasket. I got out yesterday for about an hour before it started to back fire on me and shot a huge black cloud of smoke out. I couldn't get it started so my buddy towed me back to the pick up point and after about an hour of sitting it started up like it was no issue at all. I got my beast back yesterday and have all weekend to get into it. Anything would be great thank you! Note a slight cloud to the left of the photo. Couldn't get one of the thicker smoke

      Hi, I have been around everything with a motor since I was little, and finally purchased more to get my husband, and kids involved. I have 4 quads I will be searching around for information on. I have two 2002 Suzuki LT80K quads, a 1997 Yamaha Timberwolf 250, and a 1996 Kawasaki Bayou 220. I have had different ones throughout the years, and plan on buying another Yamaha Banshee. I plan on trying to learn more about all of them, so I can customize some of them. I know nothing about them besides how to race them, my dad always took care of the rest, but figured it was time for me to learn.

      I just bought a rare beast!

      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!

      Trail Tire Valve Replacement
      By Gwbarm
      Have you ever been on the trail and your tire valve goes bad. No way to break down the wheel and replace it. A lot of you probably know about this already i had heard of it but never used one. Just punch out the old one insert and tighten down the nut
       

       

       

       
      So far it has worked very well.

      01 bear tracker stutter/ bog, electrical ??
      By Thumpinhard25
      First thanks for any help guys, new to the forums and it's gotten me this far. I bought a 2001 bear tracker 250 for my family to get around the dirt bikes races. It wasn't running right and had a high idle. Previous owner thought it was a carb problem, so he ordered a new Zoom carb and new intake boot, but it still had the same high idle. ( I believe he had the throttle cable adjusted wrong, because it idled fine when I put it back together) So I tore down and cleaned the stock carb, and it started up and idled fine, but needed to have the choke 1/2 out to run.  I swapped to the new zoom carb and had the same issue. Choke half out bike ran ok. I played with the needle and the pilot screw with no change. ( bike did seem to be running rich though, but didn't get better when I tightened pilot screw or raised meddle) I Took it to the races and once I started bouncing around in the cattle fields the quad started cutting out real bad. It would barely run.  Sometimes it would run with choke off, sometimes choke 1/2, sometime choke full. I cleaned carb again, checked float level, and boots, no change still wouldn't run. Then suddenly it started running ok again.  This makes me believe it's an electrical issue rather then carb. I know there's no air leak, it's been checked, both carbs are clean( I've swapped them out a couple times, it starts up immediately and usually idles fine. But then bogs down/ or stutters under throttle. I saw the post on the guy who disconnected his rectifier and reconnected and suddenly it started working again, which lead me to believe it may be electrical and not carb.  So any advice on what I should check? Any way to test the CDI or rectifier?  Once again, I appreciate your help.
