One of my new riding buddies has a 2015 YZ125 and yesterday at the track, after hearing him ride, I told him the bike just didn't sound right when it got on the pipe.. Way too fat and boggy. I asked what ratio he was running and he said 32:1, which he said that's what the bike calls for (I haven't confirmed this).. He's the second owner of the bike and is 99.9% sure the previous owner wouldn't of even known how to re-jet the bike, so we're assuming the carb settings are all stock.
I know oil ratio and jetting specs run hand in hand.. but if the carb settings are indeed stock, and the manual does call for 32:1... where's the best place to start? Try leaning it out with the clip setting? Any comments are much appreciated. Thanks guy
Positively, absolutely 110% obsessed with anything MOTO.
