I was riding my scooter home one night from a long 88 mile scoot and halfway home the lights started to flicker and then just turned off. the bike itself was still running with no problems except the lights didnt work. I parked it and picked it up to finish the ride home the next day without issue except the light still did not work. a few days later the scooter just died completely while i was riding it to work, it started to putter then jolted a few times and finally just stopped. i replaced the battery to the bike and it drained every day all the way down to where i had to put it on the charger each night. it will run after the charge for at least the day but the light still will not work and I constantly have to change the battery. what is wrong with my scooter
It sounds like your alternator is not charging the battery. Fit a new battery remember to undo negative lead first to remove and fit positive lead first to refit the battery. When the new battery is filled please charge it using less than 1 Amp DO NOT use a car charger or try to jump start it. Your new battery should show 12.5 to 13 volts on a meter for a 12 volt system and 6.3 to near 7 volts for a 6 volt system. Start the scooter and check across the battery terminals your meter should show about 14.4 V for 12 volt battery and about 7.5 V for a 6 Volt one. No voltage increase means your charging circuit is not working. Either the alternator or rectifier(regulator) are not operating correctly. Worst case scenario is both units dead.

The water getting in is corroding the electrical contact from the speed sensor's wire, situated on the transmission. This can occur at both ends: either at the sensor or at the indicator.
You will have to find out which by looking at the sensor connector: If it's corroded then clean it thoroughly, crimp it a little more then insert it firmly and insulate it further with some hot glue. If the connector there is in good working order then follow the wiring up to the instrument panel; - check for wires with broken insulation and repair that. Finally if all the wires are correct then the fault is at the indicator: take it out, clean it and insulate both the connector and the instrument panel itself - the water might seep in and short the electronics board.

Something is wrong with the fuel supply. Since you have flow thru the return pipe it means that the problem is either in the pressure regulator or the injector .
To check them you will need to do 2 tests:
1 - to determine the location of the fault detach the fuel line from the injector, put it in a can and try to start the engine - if the fuel squirts with pressure then the regulator is good and you need to test the injector itself;
2 - connect the fuel line back to the injector, put a multimeter across the contacts and check the voltage when you try to start the engine - if it shows less than 6 volts you have an electrical problem (either a faulty wiring or a defective ECM); if it shows over 6 volts you have a clogged injector - the entire fuel system will have to be cleaned.
