My 2014 CR125 is the ultimate add-gas-and-ride bike. I fiddled a bit with jetting when new (one leaner on main and pilot, I think) and have pretty well left untouched since. Not perfect, surprisingly good.
I am due (likely overdue) for top-end as I approach the 70 hour mark. Of course, this means installing the 144 kit that came with the bike.
I have searched (including the jetting thread) and found lots of good info about jetting specific bikers and solving specific problems. There is not much for what I want to know - what jetting changes should I expect to a well-running stock 2014 CR125 when I install the stock 144 kit?
The closest answer is from Kelly. Older model, but he went leaner on main (although he said it ran rich on top as 125) and richer on pilot and needle.
General advice appreciated, but ideally someone has gone through the same exercise and can share their experience.
