Ok guys, I need some guidance here. Now this is my first ever mini bike so be gentle lol. Replaced the original engine with a 79cc Predator, also bought a new centrifugal clutch to fit as it was a 5/8 instead of 3/4. Now the original clutch slid right off no problem, but I think the new one is seized or frozen on. I THINK I put a light coat of either 30w or WD40 on the output shaft before I installed the new clutch, but honestly can't remember. I do remember having to LIGHTLY tap the key into its slot before I bolted it up. Did I do something wrong here, or is this a normal occurrence? Was there a step I missed when I installed the new clutch? Any help here would be greatly appreciated!
