My 2000 gsxr 600 ran good all summer and sat in the garage this winter went to start it and now it wont idle with out the choke on even after it got warmed up too 200 degrees what do i check for to fix it

take it and have the engine codes ran that will tell you whats up with it sounds like a bad spark wire or coil but could be something else

fuel filter? air filters? Drain gas lines and tank.

Around 2000 was the first year for fuel injection for the GSXR 750. It really isn't a 'choke' in the true sense of the word. It's a device that causes a high idle similar to an 'enrichener circuit' to warm up the bike engine. There should be no damage to the engine by leaving it on for a short ride so I'm thinking there was an unlerlying issue with the bike that the previous owner left undisclosed.

Around 2003 that device was abandoned due to the advancement of technology in fuel injection and was no longer needed.

After typing this response I just noticed the original post date was in 2012 and I'm sure the bike has been either repaired, sold or crashed by now but maybe this answer will be helpful to someone else.....

SOUNDS LIKE THE CARB LOW SPEED JETS ARE CLOGGED , THANKS TO THIS PITIFUL GAS WE GET TODAY ,I USE A ADDITIVE CALLED SEA FOAM IT WORKS GREAT JUST ADD TO FUEL EVEN WORKS FOR WINTER SET UP TOO

HOPE THIS HELPS

try draining your fuel tank and running it with fresh gas.

Try to adjust the idle speed Mr.If your bikes been sitting over winter there could be a blockage in the idle circuit in your carby,in which place it will need to be cleaned.....Was i helpfull??. hope this helped.

crank sensor likely-may be distributor sensor but my 98 sport was crank sensor situated in bell housing timed by flywheel
