I am wondering if anyone out there knows what the header drop measurement is for the 107'' Pilot Rc Yak 54, I am installing the EME 120cc with canisters. I have searched every which possible way on the internet to try and find some kind of measurement but I have had no success, I have a ruff guess what the measurement is but not an exact.


I am new to the 100ccer's and exhaust setups like this, any kind of help or guidance would be much appreciated...
