Dinli diamond back head scratcher


Recommended Posts

I posted earlier looking for a wiring diagram, but maybe someone can help me with the problem if they’ve had it before. 
 

The quad Will start and idle ok, when I open the throttle it will rev all the way up until WOT and then it dies back down to idle, and if I keep the throttle wide open it will rev back up. It will do this over and over and over. 
 

I replaced the carb, (twice), Rectifier, battery, and spark plug.  The Stator ohmed out to the proper specs from dinli.  The other issue i can see is I’m not getting 12v on the choke circuit. The lights don’t work either. 
 

possible bad key switch? Maybe the new rectifier is bad? All the contacts on the key switch also ohm out properly    

comprsssion is up to 125 psi and spark is there. 
 

Reed valves look great.....

 

im at a loss. Any trouble shooting advice would be appreciated.

      From Arkansas. Just bought a 2012 Gator 850i RSX because I could not pass up the price. BUT it has an idle problem. So, to be honest, I joined just to get a service manual. I have a choice: 1)Buy a hard copy: ~$100; 2)Buy a CD ~$35.00; Get a direct download for free posting 10 times; or get a download for $29.00 (subscription). Haven't decided what to do yet.

      Hi, I am having issues with my TRX350D fuel pump.  It suddenly stopped running so I have replaced all the fuses and cleaned all the terminals.  I have fitted a new pump, fuel cut-off relay and rectifier.  Still nothing!!  The pump runs when attached to a battery.  The engine will start on the choke and the filter fills with fuel but it will  not rev and dies when the choke is closed. I have power to the relay but nothing at the pump black/white wire when cranking the engine.  Any ideas where to go from here would be very much appreciated!!

      Hi Guys!

      New member and could really use your advice. I would have to believe this has been an issue for others but a search here came up with nothing......? (Probably me not doing search correctly)
       
      I have an 87 Big Bear 350 YFM350FWT
      The OEM Mikuni BTM carb is shot and would rather replace than rebuild.
      It is no longer made and I have had good luck with NICHE carbs so I ordered a #K-CRB-0006 This was what they said was replacement when ordered. This Carb only uses 1 Throttle cable. The Slide is linked so it uses one. (OEM had 2nd cable coming through top to move slide)
       
      Problem is when I ordered a replacement Cable from NICHE (#C-CBL-0061) the Cable wire is a little short, not allowing Throttle to return all the way down to Idle position. I called NICHE and they are at a loss. Haven't gotten back to me after 2+ weeks.
       
      What would you recommend other than a carb rebuild?
      Can I just use 1 of the OEM cables (It is the right length) and snip/disconnect the other that went to top of Carb for Slide?
      Or ??
       
      Thanks in advance for any advice you have!!

      So I've got a Hisun 550 that I was doing some work on that required removing the CVT and it's housing. Upon attempting to reinstall the clutch, sheaves, etc, I found that the belt no longer fits - it's far too wide. None of the parts have been replaced, they're all OEM. Exactly the same parts as what I took off a few weeks ago.
      To be more specific, my belt is 1.25in wide, but the gap between the clutch and the primary sheave is only 7/8in wide. I'll include a few photos to explain.
      Has anyone ever experienced such a bizarre problem? Any help at all would be appreciated, I've been stuck on this for a month. I'm open to just about any suggestion.
