Reply To: Jetting a GT125R – 2017 ..?

Clearances are spot on; on both cyl, intakes, a .010 slides in, a .020 dont. and ex: 020 slides, 030 dont.

However… the plot thickens …

Seeing the camshafts, I noted a strange difference… and checked with the manual. Alignment is off! On rear cyl, both index-markers points straight up, and not to each side… (see pictures !!!)  Front:
