If you can take the pull start cover off you will be able to turn the crank by hand or a socket, or, put it in a forward gear and gently nudge the bike forwards so it turns the engine over. If the timing mark goes right past the hole then you'll have to nudge it right round two whole turns of the crank so watch carefully and nudge it gently. If you have the spark-plug out it will turn easily, and if you have the cam cover off(if it has one) you will see when it's getting near the right place before the mark gets into the timing hole.

I think, if I'm going to take that cover off I'll order a new pull rope assembly and put it in while it's off. I'll save that info for when the new rope gets here. First unfortunately, I think I need to pull my carburetor. I'll start a new thread on that. Thanks Mech 🙂

I use a screwdriver in the hole and turn slowly to tell when im at top dead center with a finger over the hole to tell when im on the compression stroke, but timing marks are good too if you can see them while turning over the engine.

      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.

      I did a compression test on my 2005 Bombardier Traxter 650 CVT and it's 75 PSI.  service manual only talks about leak down test.  No specification for engine compression the manual.  What does 75 PSI tell me?  Thank in advance.
       
      A little history of this machine.  640 miles.  Picked it up about 2 years ago, not running. Probably the computer.  Tested all circuits and confirm it was the computer.  Long story short, I watched a Youtube video and fixed the computer. ATV now started and runs.  BUT, it tops out 20 MPH.  I cleaned the carb 3 times also using a Mikuni carb kit after the second time.  Slide in carb is going up and down.  Only adjustment for fuel is at 1.5 turns out.  NGK Sparkplug had soot on main part but brown on the electrode.  Champion sparkplug is brown.  I check CVT clutches and they both appear to engage like they suppose to.  Checked valve clearance it's 0.00, I can't get any feeler gauges in-between.  I check timing chain I believe it's in the correct position and hasn't skipped.  I removed muffler plug and drilled into muffler to try and make sure it wasn't plugged.

      My uncle bought a Baja 250, 2006. Knew there was no spark since the get go. He don't know anything about quads so is getting me to help him try to get it running...
       
      battery is bad so I connected battery charger to it to crank it over , cranks over well , but no spark .... 
      Lights and everything work fine , but with each crank over using the e start switch , the display reads 999 888 777 666 ... Right down to 000 and repeats itself . 
       
      He managed to get a parts bike , I changed over the CDI and the coil and the stator from the parts bike and there was another black box by the voltage regulator I changed over ... I used my multimeter to confirm as much as I could works , it's hard without knowing which wires are which , and I cannot find any diagrams online for this bike ? 
       
      Do you think it could be the Killswitch? There's so many wires coming from there I don't know where to start . Also I should mention it appears the fan on the front of the bike has been taken off (the wires have been cut too ) 
       
      If this bike sparked it would run . The previous owner said he parked it one day and it just wouldn't start after.

      Hi All
      I have a 2012 Coleman 500 Outfitter that keeps fouling out the plug within 10-15 minutes 
      not sure where to start

      I have a 1988 Quadrunner 250 2wd. My brother in law sold it to my son for $20...had been sitting outside for several years. Got it home and had it running in about 30 mins. Ran it a bit and then went to looking at the carb as it was having trouble idling. Was getting it pretty close, then started losing spark...Also, it wouldn't start up every time...only about 1 in 5 tries. Anyway...now, it has what I can only describe as "intermittent" spark. I can get 1 light spark right when the start button is pressed and sometimes one when it's released...but none while cranking. 🤷‍♂️

      I have replaced the spark plug, ignition coil/wire, and traced wires best I can. I noticed a couple frayed wires at the pickup coil where it enters the case. So, now I have the cover off, stator and pickup coil out and trying to test the coil. I do have about 114 ohms resistance for pickup best I can tell. And I can read minute voltage when I drag a magnet across it. Could it still be bad? Can a bad ignition switch/button cause this? (I did have the switch off to oil the choke cable)...pulling rope makes no difference though...any ideas or help would be greatly appreciated!!! It's the intermittent part that's throwing me off!
