I have a 2007 gsxr 600. When i start it up and its cold it runs fineas soon as it heats up to temp it starts sputtering and loses power and it dosent idle very well like its missing bad pls help thx

Plugs leads or coils breaking down when warm. Or it could be tight valves when the motor warms everything expands abe if there is not enough clearance in the valves they don't close fully and allow combustion pressure to leak out. To test this do a compression test when hot and cold and compare.

BUY A testmeter from ebay 7 quid, run bike and check output, no more than 14 ish volts put dial to 20 anti clock wise, also feel the resin on the back of the unit, if all bubbled a sign it is shagged. test with meter pins on the battery terminals,

Could be ignition fuse. If not that then check the large block connectors which are usually located on the left hand side at the front of the bike behind the cowling beneath the handle bar. These connectors are notorious on GSXR's

you need to replace the air temperature sensor. looks like this one https://www.ebay.co.uk/itm/Suzuki-GSXR-TL-SV-AN-600-750-1000-Air-Temperature-Sensor-1996-2009-13650-61B00-/182447458716?hash=item2a7ab7499c:g:-rYAAOSwopRYmblq

The biggest difference is that the 2007 GSXR 600 has fuel injection instead of carbs. The FI symbol will alert you that the sensors on the Fuel Injection system have found a problem. When that happens, a dealer will be needed to hook up a code reader to see what the problem is. A dirty air filter is something you can fix. A fuel mapping problem is for the dealer to fix. Minor FI problems still let the bike run. Major problems shut down the fuel system so the engine will not even start. Other than that, just be sure the bike shifts smooth and easy and that all electrics and brakes work properly. How old is the battery? How much life is left in the chain? Does the clutch operate properly? How soon before new tires will be needed? I hope this helps. Please rate my answer.

Low beam switch may be bad. use a meter to check for power to lowbeam side of lamp. cleaning with electrical contact spray may help.

try replacing the fuel filter.

200° is quite warm...
If the engine wont turn over, probabily you have a bad battery, a bad starter or a bad starter relay, or bad connections.

A hot engine has more compression. If the full battery power doesn't reach the starter it won't turn over...
