Hello all, 

i just rebuilt the top end of a 99 Bear Tracker 250 and it can’t get it to hit off of gasoline or starter fluid. Occasionally it will backfire. Right now I’m just trying to get it to fire off without the carburetor like I’ve done a thousand times before with other engines. Usually there is no response, but occasionally I get a backfire through the intake. ISeems like it’s out of time, but I don’t see how that could be possible. 

Here’s what I know:

1. compression 120psi

2. all timing marks are lined up after numerous revolutions. 

3. Strong spark. 

4. Valves adjusted correctly. 

Thanks in advance.

      Looking for Quadrunner Flywheel Starter Clutch Gear race diameter
      By logray
      Hi all, 

      I am wondering if any of you have a Clutch Starter gear from a 1988 era quadrunner 250 sitting around that you could get me a precise measurement of the outer diameter of the race the sprag engages onto, for me? I need to machine a damaged race down and install a hardened sleeve and need that measurement (it's on a different gear than the OEM one, so I can't buy and use a OEM gear).

      99 Bear tracker no neutral or reverse light or start button
      By OldATVowner
      Just getting into this issue really. Been replacing solenoids but now I'd like to track down the problem. This time I'm not getting neutral/reverse lights or start button. Was on a creek ride when it started doing this recently. It cranks by arcing the solenoid and gives me no light or start button but if I crank with the pull cord....the neutral light and the button work. Turn it off and try to crank with the key and nothing. I'm looking into the safety switch issue tomorrow and re charging the battery. Just figured this was odd enough of a problem that you guys might be familiar. Thanks

      What's with all the UFO stuff lately?
      By quadmaniac
      So here's a topic for anything goes forum and to get a way from the china virus stuff...lol. Has anyone been noticing the small drips of news about ufos and the government confirming? President Obama has an interesting late night segment. How warm and fuzzy do you feel when an ex-gov official confirms objects in the sky they can't explain...

      Starter not staying engaged while cranking
      By HoldenBoy
      Hi all,
      Looking for some help on a starter/bendix issue. Can Am outlander 450 2017. While cranking to start, the starter spins and engages into the ring gear. After a few seconds the bendix retracts while still spinning and there is no damaged teeth on the drive pulley.
