I also found info 'exhaust type for YX motor' differences on your website, you said there, honda type also have almost horizontal intake port. But how about the motor in the pic? I'm not sure...
I have asked the guy for the stud size but haven't got info yet.
T bolt whats the power and torque difference and reliability between the yx 150 and 160 or is that classified info
I'm gonna get one or the other off of you soon and do they come with the electrical (put the carb, pipe and hook up the wires and its ready to go?)
Flat flange where the intake bolts to the head (Honda style) like in the pic. If the head was at a 45 degree where the intake mounts to the head its a KLX.. If it has a Honda intake style the exhaust is Honda. If it has a KLX style intake the exhaust is KLX...
