You need to find out why the temp is going so high. Is it really getting that hot or do you have a bad sending unit?

Adjust the carburetor.

need more info is battery full and connected all power wires ok. You need multimeter $10 repco or supercheap there are cheap ones easy to use set to 20< volts test positive wire to ignition for power after you check battery without anything connected to it.

Bike batteries need full charge to start a bike, if there is less than full charge you can't even push start them. No click generally means no charge, the clicking sound is the solenoid working.
When you just start the bike and run it at idle, even fast idle. The battery does not get sufficient charge. What you take out of it to start it, is more than what you put back in it when you run it at idle. Bikes need to be at road speed to charge efficiently.
Also just sitting around they discharge, you may have an earth leak also. That causes your battery to discharge at a more accelorated rate than normal. If it has a clock in it, this bleeds off a small amount of power but still enough if it isn't being correctly charged.

If old gas sat in the carb.s for more than a month it starts to dry up. As it drys up it leaves behind a varnish like film that stops up some very small ports and pin holes inside a motorcycle carburetor. It is also very hard to get out. You can try this before you pull the carb.s for a full cleaning.Use a product called Seafoam, get as much gas out of the carb.s as you can. use a turkey baster and force the seafoam into your carb.s fuel line that you take loose from the fuel tank. Let that set for say 1 or 2 days. then hook up the fueltank with a mix of good gas and seafoam, (not a lot but enough to start it up. Move the cycle outside as the seafoam will make a lot of smoke if it does start up. If that does not clear up the problem you may have to pull the carb(s) and remove the blows to clean the inside. If you have to do that do not DO NOT MESS with any adjustment screws. Just take the carb. bowl off. Do not mix up any internal parts. It is best to work on a large sheet so if you drop a small part you can find it, you do not want to be missing some tiny spring or screw. Hope this Helps Fix Ya Up..

what model or you working on. I'm guessing it is a gsx-r but till i know for sure i'm not going to be to much help. I would like it if you could get back to me with the yr and model, when i have that i can get you the wire diagram and help you get it fixed.
I'm not going to lie about this but if your not confident in wiring it may be something you want your local shop to handle. If you take your time and ask for help with things your not sure about i'm sure you can handle it without a problem.
I'm looking forward to hearing back from you with the info i need to help you get the bike running like it should.

Hi,,first thing is to clean the carbs,,if that dosnt solve the issue ,i would be looking at the coils.and cdi

FI stands for Fuel Injection. Sensors on fuel system have found a problem. Many problems are simple, like a dirty air filter. Some problems are serious, like low fuel pressure. Some problems are "fatal" like fuel mapping gone bad. Fatal problems will not allow the bike to run. You will need to get the bike to a dealer and hook up a code reader to see what the sensors have found. Bear in mind, be sure the sensor hasn't gone bad.

This new gas that everybody is selling with the ethanol goes bad very quickly try using some lucas fuel stabilizer and if that does work check the run / not run switch above the start button if it got some corrosion in the switch it would allow the engine to turn over but not fire. Good luck riding season is right around the corner.

If it has a Clutch cable check the adjustment. It always need adjusting after putting in new clutch. If it has hydraulic clutch check and bleed the clutch fluid. If there is air in the lines this can cause a problem. Make sure you purchase a Service Manual it is a mechanics best friend.
