I have a problem with my 1986 honda 200sx. It idles good, but for some reason ittle start revving high. It also drives by itslef when it does that. It also wastes a lot if gas, but im more worried about the iding issue. I have the idle low right now so it wouldnt do that, but when i fix the idle, it idles good, but itll start revving up. Please help me

Hi. How long has it been doing this, and did you do anything to it before it started doing this ?

And are you saying it sits there idling at the right speed for a while, then starts revving by itself ?

You should check it doesn't have air leaks between the carby and the head, and probably clean the carby and then check it's idle mixture adjustment.

I've seen that a few times and most times it's a vacuum leak between the carb and head, normally a gasket or oring not sealing properly. Alternatively, i've seen that happen also as a result of a sticky throttle butterfly in the carb or sticky throttle cable.

      91 quadrunner lt4wd shifting issue
      By Joeguy
      After i did my rebuild it seems to not want to shift well. I think the cable is alright, and when it does shift its nice and solid. I have to basically use my hand to shift and i have to pull or push it very far, like max travel, to get it to shift. I also tried adjusting the clutch set screw. Any ideas where to go next, or maybe i should just grab a new cable to try.

      I am unable to find a wiring diagram for this UTV.  When I turn the switch to on, the contractor does not engage.  The Brake pressure switch and the parking brake switches work correctly. What else should I be looking for?  All of the diagrams I have found are for newer models and the wire color coding is different.
       
      Thanks

      I have a 2009 Honda Rancher TRX420FA with shifting problems.
      Usually it shifts ok when cold but after couple minutes it will stop shifting with no codes.
      The 1st shift clutch oil pressure when in first gear is 74psi. The 2nd shift clutch oil pressure when in second gear is 74psi.
      The 1st shift clutch oil pressure when in neutral is zero. The problem is when the tranny is in neutral the 2nd shift clutch pressure starts around 10-15psi and builds to 20psi. Is this normal?

      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

      Fuel issue
      By Dsluder
      I am having an issue with a hs500. I bought it broken and have been trying to get it running. It seems to be starving for fuel. If I put my hand over the intake it will crank but will not run for very long because I'm not able to get the correct airflow with my hand. The things I have done so far are. Replaced the fuel pump, fuel filter, mass airflow sensor, idle air adjuster, fuel injector, cleaned the throttle body, replaced the ecu, and still the same issue. I notice the injector does not spray when removed from the head. I dont know if that is common. 
       
      I am out of ideas on what to do next. I have removed the fuel line from the injector and it is getting plenty of fuel. If anyone has an idea on what could possibly be the issue I would be happy to try anything at this point.
