Welcome Kymco Owners!
I have a friend who has a 2018 UXV 500i. He says it was running fine , then one day it wouldn't start. I took a look at it, and it seemed to me to be cranking much slower than it should. I put a brand new battery in it, and made sure it was fully charged. And cleaned all connections. No improvement. It still turned over slowly. Occasionally it sounded like it was trying to start. All of a sudden now the starter motor spins ( and sounds like it's spinning fast) but it's not turning over the engine. Am I correct on assuming that the starter clutch is bad? And can these slip and cause slow cranking before they quit completely? Is the clutch hard to change? Thanks!!
