My bike is a 2017 KTM 250 XCW. I just wanted to let you know what a change in my riding experience has been since I started using the Smart carb this spring. I no longer have to change spark plugs every ride or two. I am still using the same plug since riding season started. (1000 km so far) Thanks for that!! I wish I bought this years ago! I have been highly recommending the smart carb to all of my carburetor buddies. It’s well worth the money!! Thanks again!!

2018 (non-tpi) 250XCW – Rebuilding to 300XCW running the SC2 36
We live in Northern Utah and ride all around the Intermountain West (UT, CO, MT, ID, WY), predominantly around 5,000ft – 12,500ft depending on the time of year/season. This carb has been a game changer when it comes to ensuring the bike is always running crisp and proper, regardless of altitude, temperature or location.
This is hands down “The Best” investment you can possibly make for a carb bike. You get the flexibility, fuel efficiency and power that our fuel injected 2-stroke brothers can only dream of! No more messing with jets and that good old fashioned 2-stroke power band that your mamma always warned you about growing up.
After 150 hours of hard enduro, single track, desert riding, all around shenanigans and too much snow to enjoy ourselves in the mountains any more – it’s time for a rebuild on the motor and carb.
Cheers SmartCarb – You guys make and incredible product!

I’m amazed at the quality and ease of use of my 36mm SmartCarb SC2. It’s so easy to get dead-perfect jetting that it feels like cheating. In fact I’m so impressed with it on my KTM 250 XC, that I went straight for the “easy button” when I couldn’t nail the jetting on my son’s new KTM 65SX and immediately contacted these guys for a SmartCarb suitable for it. Like a skid plate or hand guards, the SmartCarb is now an essential piece of equipment on my 2 stroke cross-country bikes. Not only does the SC2 exceed my expectations, the support and responsiveness offered by SmartCarb is second to none.
