It doesn't appear they addressed the major issues in the current generation. While I love the counter balancer and some other improvements, until they solve these issues I'm going to continue rocking my 2011.

1. Max horsepower is only 47. Previous generations were 49-50 and have more top end pull, current generation has better mid range power.

2. The gear spacing between 2-3rd gear is much too narrow. Gearing alone will not solve this problem

3. The Mikuni carb is temperamental and requires frequent re-jetting. Where the previous Keihin carb stayed jetted well with temp ranges by as much as 25-30 degrees, the Mikuni window is much smaller in 10-15 degree increments. You can get away with a Winter, Spring, and Summer jetting process in the Keihin, but with the Mikuni carbs you often need to re-jet week to week or ride to ride depending on weather.

The first two issues cannot be band-aided, and the carb issue can only be solved by going with a Lectron. I admire the incredible advancements from KTM, but in my view the current 250sx is a very flawed machine and not up to the standards of the rest of the lineup.

Sandman mind sharing your jetting specs?

My '18 with proper jetting and a PC pipe/silencer made almost 51hp on the dyno.

The carb is amazing and with my jetting I only need to change it when it drops below 50 and we are talking a clip position change. The Lectron is junk on these bikes. Anyone that says different are not riding the bike hard in moto.

I agree on the gearing. Dropping to a 49 helped, but I want to try a 48 and also maybe change the front sprocket too.

These are valid points but not deal breakers IMo. A pipe/silencer and powervalve adjustment gets the top end revs back, 1 less tooth on the rear helps with the 2nd to 3rd transition and the Mikuni jetting changes can be made in minutes. I have the carb settings down to where all I need to do is change the main depending on conditions, but yes, I would welcome a Keihin carb to the party...

You may suggest all you want, I have many hours of seat time on the new gen bikes and the takeaway is real world perspective. The new gen is a good bike in many ways, but it's actually inferior in some very dramatic and important ways, and superior in others.

You people that think the Mikuni carb is junk and temperamental and whatever word salad you want to throw at it are nuts. I swear so many ppl like to pretend they are the ultimate mechanics that knows all and if you don’t do it their way THE BIKE WONT RUN AT ALL.

Stock, yeah it’s heaping shit. However. You throw a JD Jet kit in it- and it’s a badass carb that works phenomenal. I’ve been riding the same settings since April.

It’s a $100 performance part I would’ve bought with a Keihin too. But this is vital and what the hell do I know
