I have a suzuki 750 gsxr 2002 the bike bike starts great idles perfect but when I ride for bout ten mins and I have to down shift and stop when I start to go again it stalls and bogs down

If it's 54 outside and the fan is not running because the cold air is passing through the radiator and the coolant is doing it's job. Then you come up on a red light and basically all of the sudden that 54 degree wind chill has somewhat stopped (because 54 degrees outside and going 50 mile per hour creates quite a wind chill) the engine will heat up, cause the thermostat to open allowing the fluid to flow through the system. Now the fan kicks in at 220 degrees and begins to cool everything back down or you start riding and the wind cools it back down again...........I hope this helps a little. My bike heats up quickly too especially after riding for awhile and then stopping at a red light. I flush my coolant system yearly before the winter. It's generally recommended every 2 years.Ref: https://www.gixxer.com/forums/80-06-07-gsx-r600-750/294175-rapid-heating-idle.html

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

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.....

when i shut off my 2002 suzuki motorcyle it run perfect then went to start i and have no power battery good have no light on dash no head light brrake light everything is dead what could be wrong can you help with a idea thank you dave

Hi This is most likely a problem wih the ignition switch
Next time this happens use jumper wires to bypass the key switch

You might have a leak in your tube mount between the carb and head. Let the bike idle and spray some starting fluid on the front of the carb. If the idle shoots up, you have a leak. Either cracked/weatherd or not tight enough

DONT WORRY BOUT TOO MUCH FLASH IT JUST MAKES U EASIER 2 SEE, AND BEING A BIKER OF 30+ YEARS , THATS A GOOD THING

When you are on the bike and riding do you still have the choke out? And stop spraying starter fluid into the carbs..bad bad bad.... bikes start with out that stuff and if you need it then something is wrong.. your gonna mess something up doing that....let me know about the choke and we will go from [email protected]

Hi and welcome to FixYa,

Your description indicates an electrical malfunction. Offhand, the jump start and charging is significant. This points to the bike's battery not charging. Suspects would be:

• voltage regulator (most likely);
• connectors to voltage regulator (likely). Check/clean corrosion/burnt marks;
• stator and/or the 3 wires coming from it (least likely).

Good luck and thank you for using FixYa.
