loss of compression

[HSV_Hunny04]

i have a 140cc BSE
recently it has been hard to start i can just kick and kick, so my question is easiest way to check my valves? or what are the gages size i would be needed? keep in mine i am a chick but i do have a mechanical mind so i am willing to give it a crack to see if i can fix it,
besides the vales what else could be stopping it from kicking over? also have replace apart plug get plenty of spark and have a new carby,
hopefully someone can help me

Yeah i'd say valve/rocker clearance's need doing.
You need feeler gauge's with a .003"(.76mm) and a .004" (.1mm)
Inlet is .003", and exhaust is .004"
