You have 'Windows' in your carbs with that model, with the engine stopped, open the throttle slowly and see if bothe the carbs open fully at the same time. There is an indent on each throttle slide, you will see it appear in the window. Link to comment Share on other sites More sharing options...
YPVS TONE Posted November 1, 2009 Share Posted November 1, 2009 Have you got the slides in the right carbs as they are handed.The cutouts at the bottom of the slides should face back towards the airbox. Tony. Link to comment Share on other sites More sharing options...

Use the knurled screws to adjust the idle speed, havent you got a manual? Link to comment Share on other sites More sharing options...

I imagine they are ...yes (the biggest of the two) the trouble is...its years since I had a 2 stroke twin and cant remember what the procedure is You wouldnt want one cylinder doing all the work, it should be shared equally between the two. i could guess that you remove one plug at a time and set each side seperately but dunno for sure...maybe YPVS Tone or Merv or anyone else who knows can enlighten us?

YPVS TONE Posted November 3, 2009 Share Posted November 3, 2009 What you need to do first is with the engine Stopped look on the RH sides of the carbs and you will see a window on each carb. Open the throttle fully and make sure both dimples in the slides apear in the centre of the window if not adjust the cable on the top of the carb to raise or lower the slide so both slides are at the same height with the dimples in the centre of the window.Now start the bike and warm it up. Stop the engine and remove the RH plug cap and put a spare plug in the plug cap and rest the plug on the cylinder head.Start the engine and adjust the throttle stop screw on the LH carb (the bigger screw on the side of the carb with spring behind it) until the tacho reads 1000RPM .Stop the engine and remove the spare plug from RH plug cap and put cap back on the RH plug.Remove LH plug cap and put spare plug in cap and rest on the head.Start engine set tickover on RH carb to 1000rpm. Stop engine and remove spare plug and replace cap on LH plug.Before you restart engine unscrew each throttle stop screw out the SAME amount say about one full turn each. If the tickover is to high or too low screw each throttle stop screw in or out the Same amount as each other to keep the carbs balanced. Tony.
