ok.  I took the head off and losened the cylinder and pulled it up a little so the rings would still stay compressed.  The cylinder moved pretty freely up and down.

I also shined a light down the timing chain and around the crank.  no kinks.

So the piston is jammed inside the cylinder it sounds.   I would back the piston out and see if that’s the problem. 

If the crank spins freely then the piston is jammed inside the head and that’s not good. You can scratch the cylinder walls.  Maybe a rings not compressed and sitting in the groove right.

I hate to say it but I would pull the head again and see if the crank spins. You have to be sure that nothings inside the engine.  

Habs you tried to spin it both directions.  I feel like it would have to be the timing chain. Be sure it’s all the way up and not kinked down below.

Ok, looked it up, for the forum:  In:   .10-15mm

                                                    Ex:   .20-25mm

I got it as close as I could- the valve clearance tool I bought didn't go that small...  just down to .20mm so I just tightened it farther on it to try and get down to .15mm.  If Its running bad, I'll get a different set and get it exact.  Any tips as I put it back together?

So timing and valves are good ? 

If so just re tighten everything good and spray a drop of wd-40 into the cylinder and spin the engine a few times to get the piston up and down the cylinder. 

Did you put the new rubber rings in the valve cover caps.  I like to use a drop of high heat scilicone on the edge of them caps. They leak oil for some reason.  

lastly  after it’s all back together I like to  press the start button with no spark plug in to cycle the engine a few times to pump oil up into the head before it fires up so it does not scorch the cam.

I would do a quick clean on the carb just to make sure it’s giod to go and nothing’s in any of the jets.  It has happened before.  

1-3/4 turns out on the fuel air mixture screw from a snug position. 

Put the air filter back on before you dial it in with the final adjustment. 

Floats prob stuck. 

You can try to tap it with the back side of a screwdriver to maybe free it up.

      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!

      Heres my story. Kinda long. I guess I was a late bloomer when it comes to quads. I had never ridden a quad in my life. Rode Dirt Bikes as a kid growing up. Back in Oct of '06 I found a Mustang on craigslist. Took it for a test drive one morning before work. Fast car. 351 Cleveland. I had planned on meeting the guy again after work. For some strange reason thats still to this day beyond me, I stopped in Hillsboro MotoSports on the way home from work. I had 6 Grand on me. There was a left over '05 sitting by the front door. It was on sale for $4999. It was $5499 OTD. I didnt even look at anything else. I knew nothing about quads accept I thought it really looked coool and I had the money in my pocket to buy it. I was sitting on it when the salesman walked up and asked... "Can I help you?" Without hestitation I pulled 60 Ben Franklins outta my front pocket and said "I want this Quad. Load it up in my truck." It was just about dark by the time I drove away from the shop. BTW, I didnt bother to ask my ol lady if I could buy it. LOL. Anyway, I took it by the house and showed her. She was kinda stunned but not mad. We drove over to a friend of mines house and unloaded it. I took it to the field across the street from his house. HOLY CHIT!!!!! I was surprised by the power. I had it for about 2 weeks and took it to Sand Lake. I was there a few hours and rolled it on a banked turn at the top of the bowl right before you get to the one-ways. When it rolled, I flew off and landed on my belly. The quad came bouncing and landed on my back. For a month I couldnt even walk. I was scared of it. I considered trading it for a 250EX. Went back to the shop. The salesman said..."Dude!!! You dont want a 250EX!!! Trust me. Just get used to it" I still wasnt convinced. I put it on craigslist for $4000. Calls were coming in. I had a guy that wanted to come look at it that evening. I decided to take it for one last ride at Browns Camp before I sold it. I was still afraid of it. After about 5 minutes I started feeling comfortable on it again. I decided right then, I loved my Honda 450 and would learn how to ride it instead of selling it. That was late Nov of '06. Work was slow for a Painter in Oregon. My new job everyday? Going to Browns Camp and ridding my Quad. I bought my Girl Friend an '02 Blaster. I rode my 450 for 4-6 hours almost every single day for 3 months. And yes, I know my way around Browns Camp pretty well. LOL. In March I bought her an '06 TRX250EX (Thank God I didnt trade my 450 for one of those) LOL Since then, I have become totally addicted to quads. I love them. Couldnt imagine not owning at least one quad. Luckily I have two. My "07 was $6500 OTD in July of '07. Bought it for my Girlfriend. Traded in her 250 EX. A month later we broke up. So, I wound up with two Honda 450's.
