General Discussion / Xciting 500cc flapping noise from engine or crank or valves
« on: April 26, 2024, 05:05:00 PM »
Hi All
I have a 2007 kymco Xciting 500cc, great ride and great scooter, i enjoy it tremendously.
I have a 2007 yamaha R6 too.
I had this flapping noise on the Kymco, i can start, ride at about 15km/h, once i start to increase speed, the flapping noise gets fast and louder but only takes about 5 seconds then it completely switches the engine off.
I was riding on the highway/freeway when it started.
I checked the bike even when i removed the Driven belt and on its centre stand, the same thing happened.
I have the entire bike stripped down to the crank shaft, everyting is perfect on the bike, bearings are perfect, nothing is damaged, nothing is loose, teh engine from eye view is completely perfect.
So what is or was wrong?
What was causing the flapping noise?
and how is it effecting the power and electricity on the bike?
