Choke and Throttle Issues

Discussion in 'Technical and Troubleshooting Torque' at netrider.net.au started by MAP74, May 26, 2009.

  1. Hey all.

    Maybe someone out there can give me a little advice.

    The choke on my VTR250 stalls the bike when I shut it off, even when the engine has warmed up.

    I have adjusted the throttle stop screw thinking this may solve the low idle speed but all I seem to get is too high or too low revs when I close the choke. To get a reasonable idle speed the choke has to run about a quarter on.

    I might have to take it to the shop for a viewed opinion but I would like a little advice beforehand to know if it could be something else.


  2. Could be a blocked pilot jet?
  3. been playing with the air/fuel ratio knob?

    whats your definition of too high and too low & normal idle rpms

    give us a tad more info, year, kms, always happened/recent? did you buy the bike like that etc
  4. Its the 2007 model with 2009 compliance plates. I've had it for about a month.

    It's a second hand import from Japan, about 20,000 on the clock.

    It was like this from the start.

    As far as rpms, I would only be guessing as it doesn't have a taco, but when I close the choke it stalls.

    I rang the place where I purchased it from and they are going to check it out on the weekend.
  5. Please don't say you bought it from Sumoto! A VTR without a tacho (i.e. speedo and lights only on the dash) is 2003 (I think) or older. It definitely is not 2007.

    I think you're doing the right thing with taking it back to the shop first (unless the shop is Sumoto in which case go to a Honda dealer).
  6. Problem solved

    It was just a simple case of idle adjustment.
  7. I love a happy ending
