the KN100.47 is a 72cc cylinder. i haven't tried opening the dip stick while running yet ill have to try that before taring it down. I've done valve chk several times. yes full throttle while cranking for compression test. my gut feeling is cylinder head problem but not sure.

i didnt add a 100cc i installed a 72cc kit. all test are fine, and the parts according to naraku are compatible.

i have a 2017 kymco 50 KG10SA scooter and did a complete rebuild with naraku parts from crank to top end and i have low compression 60psi. i am a auto mechanic by trade, i rechecked valve clearance thats good, did a cylinder leak down test thats good, removed exhaust to see if compression would get any better it went up to 65psi. i installed a KN100.47 big bore kit, and a KN100.13 cylinder head all naraku parts. any help would be appreciated why im getting low compression.
thanks Chris
