If you dont already no i have fitted a YX140 brand new
The compression is unreal!!
My mates was comparing it to a 426 or something.
Noticed that when cold with NO choke you get a almighty kick back
WITH choke she starts 1st 2nd kick with the od kick back
And once warm no kick backs, and start first kick easy
Ino it is best to start slightly after TDC as toasty/speedflash were i got my engine from just rang me and said you may think its good to have that amount of kick back and compression but ur kick start bearings wont think so...
He told me to ask you all "how to start the YX140 PROPERLY"
Videos/clip's would be really helpfull
Cheers peeps
