I was looking high-and-low for this, but it looks like mine needs running in.
Dont forget to borrow a heat gun/hair dryer before 1st start up.
It makes a lot difference in rod life.
Watch the different "sound" it will produce.
Yesterday is my 1st day I crank my KHM 21 on the bench.
I shut it down on the second tanks, the engine is producing a scarry pitched sound in the mid to top rpm.
I thought that I had a bad batch of KHM but after talking w/ my partner who ride it already, he assure me that this engine is really having different "sound".
So i supposed it was came from the ceramic pitching.
I must wait till this sunday to install the ceramic to my RR to proove it and hopefully can answer bro D question.
