Reply To: Jetting a GT125R – 2017 ..?
I did uprate oil-cooler last year, but I think the 250-cooler takes away much of the access to front spark-plug, so while experimenting, I found a cooler just in between the 125 and 250.
Old and grumpy,(?), have fairly wide engine & tuning experience, "restoring/resto-mod" on cars & mc, worked as electronic tech. (retired).
