is there any leaks from engine to exhuast

Looking for some help got my 98 cbr 600 f3 a week ago parked it at my grams it rained bike fell over neutral light wont come on and won't try to start with the kick stand down please help

Have the battery load tested. Just because its 2yrs old, does not mean good.

Check if the battery has 12 volts.
Check the battery terminals if they are corroded with acid deposit. Clean them if they are, by using a wet sponge, wet it with water and let it stay for a while on the terminals this will ease off the corroded acid deposits.
If the battery is ok and if there's no acid deposit on the terminals , thn you have to check the starter motor, it may need to be overhauled.
Better too to check the solenoid switch.
Hope this helps!

Sounds like the temp sending unit went bad and when they do it wont let the bike start cause if it goes bad while riding and the temperature goes up the computer shuts the bike down before you over heat the engine and trash it. Try disconnecting the battery and reconnect it after you replace the Temp sending unit.

First thing to do is make sure it's the kick starter that has seized and not the engine. Take the cover off the end of the crankcase and try to turn the crankshaft. Apparently these engines were notorious for doing bottom ends. Start pulling it down and see what you find..

bad gas possibly?-just a thought

it sounds like you have a big voltage drop somwhere...i would start by checking the battery cables

I learned how to set the tappits myself 4yrs ago I brought a VTR1000 and never needed to set anything 2yrs ago I went back to MG... brought the V11 nero Corsa and for those 2yrs the shop has done my maintance. However the warantee is now up so I might as well go back to servicing the bike myself. Fill in the blanks please people, whats the clearances? which markings on the flywheel do I use for which cyl's? rotate the crank which direction? anything else I need to know? ,The left side is marked S and the right is marked D. Rotate the crankshaft clockwise when looking at the front of the motor. The valve clearances are .1 mm inlet and .15 mm exhaust in Australia, I think the yankee ones are tighter? Watch the inlet valve close when rotating the motor, then find the top dead centre mark s or d, soon to appear in the window.That is the adjusting position.Or use a broom handle down the plug hole to find TDC. ,,,
