Has anyone switched out their 2017 KTM 125sx Micrapi carb for the stock Keihin carb from a 2016 bike? Just wondering what parts (other than the carb) is required for the swap? Intake boot? Throttle cable? Air filter boot?
And what years of Keihin carb would be compatible?
Thanks

Erik, We have had trouble keeping a consistent tune with the mikuni. Like for example, after getting the bike running right during the daytime, we showed up for a night practice and the bike was bogging really bad on corner exit. Granted the Houston humidity was in full effect that night but damn it required a 2-position clip needle change to get it back to good.
Just looking for something to help. Thought the 16' carb/jetting were already worked out and so I thought it might be an easier solution to change the carb to the 16' model setup.
Thanks for the help.
Here is a thread I made on TT about the TMX: https://thumpertalk.com/forums/topic/1224849-mikuni-tmx-needle-decoding/
And I see a bunch of threads on KTMTalk about the TMX jetting.
Before doing anything, I would highly recommend checking your float level and make sure your reeds are sealing. My float was off and my reeds had gaps. Fixing both helped the low end on my 250.
The Shop
Already have the JD kit installed along with new Moto Vforce4 reeds.
I just ordered a leaner idle jet and when I install it, I will recheck float height but I set it when I originally installed the JD kit.
Another piece of the puzzle was on the same night that we had the bog, we had just replaced the clutch. So possibly the clutch was slipping just enough to cover up our jetting problem on the past rides? Idk.
The boy won on it Saturday night so it seems to be getting close but he says its still has a slight bog. So I was thinking about trying the 16' carb to see if we have some better luck.
I was planning on starting with the JD jetting kit. Surely after all those years with the PWK carb they should have a good baseline developed.
