Sounds like a short or one of main sensors is burned out.. Mite get a voltage meter and see if your getting
Power or not. Go to google Image and get the schematics of the main wiring
Systems and go threw it piece by piece.
Or you mite just have a main fuse blown. Get the schematics and check
Each system good luck.

that's about 50mph,how fast did you want it to go?i would ask dealer what the top speed should be,and think about warranty service.

Has it been sitting up? sounds like the carb needs cleaning... runs about 8-15 seconds then dies... sits for a few and then will do the same thing??

Have the carb/FI cleaned and set...

repost with details..

Linda, looked for video on the wheel bearing replacement for your Kawi, no success. Check the attached links for your manual which would show how to change wheel bearing, I beleive the send link is a free manual. Good luck

Thermostats are cheap...start with that...it is the most likely to fail.

Look for dried mud behind the switch activator. It wont let the switch fully deploy. Or the switch has vibrated out of adjustment.

Does this happen when you race the engine at a higher RPM
because it is in low gear

Did you figure this problem out? I have the same problem I think it may be the tps?

You could try replacing the ignition coil. If it's failed, then it may run ok for a few seconds, but as it heats up it fails. Trying to start again immediately will be too soon for the coil to have cooled down. Leave it a few minutes to cool down and it will run again, but only for a few seconds again.
Hope that helps
