I JUST PICKED UP MY NEW/USED 99 XCR700. WHEN I START IT THE ENGINE IS RUNNING AT 4500 RPM. IT SATYS THERE UNTIL I SHUT IT OFF AND RESTART IT. I HAVEN'T TRIED TO DRIVE IT WITH THE IDLE THAT HIGH. IS THIS NORMAL OR IS THERE A PROBLEM. THIS IS MY FIRST OWNING OF A SLED.

well it could be normal...my 2000 triumph will do that too....when i first start it, it will idle around 3,500 and after about 2 or 3 minutes of run time it will slow down to normal of about 1800 rpm. If yours doesnt slow down you may want to check carb syncronization....you may have one carb that may not be closing as much as the other.

4,500 is too high, you should turn your idle down to around 3,500 when cold, and around 1,500 when warm.

OK, WELL HOW DO I DO THAT? THIS IS MY FIRST SLED. I AM MECHANICALLY INCLINED, BUT NOT SO MUCH WITH 2 STROKES

Hey, before you adjust the idle speed...what does it idle at when it is warm? or what does it idle at after you shut it down and re-start it?...if it idles around 1500-2000 RPM i personally would leave it alone unless you have problems with the sled creeping. a high idle will not harm anything unless the clutch is engauging and grabbing the belt, in which case you will burn up the belt quicker. If it were mine and it doesnt creep, i wouldnt mess with it.

Just my opinion.

i had an indy trail 488 that would do that, ide at 3000, all the time, i reset the idle and it ran awfull, might be better off if you dont mess with the idle setting, and i read somewhere that you can re-synch your idle by placing a 1/16 drill bit in the throat of the carb, under the throttle valve, then adjust your idle screw so that it allows the throttle valve to just touch the drill bit, just a thought, if i can remember where i saw that, i will post the url for you.....good luck
