SmartCarb For Honda TRX250R
$749.00 – $849.00
For those who Ride Red.
This SC2 model SmartCarb replaces the stock carburetor in Honda TRX250R quads, offering holeshot-winning performance, corner-ripping torque, and tool-free tuning.
Choose the 38mm size for best all-around performance in stock or mostly stock TRX250Rs or go with the 40mm size for quads that are punched out or if you absolutely must have the fastest, baddest quad around. In general we recommend the 38mm size for stock up to 300cc TRX250Rs and the 40mm size for bored/stroked 300cc+ setups.
Every SmartCarb ships pre-adjusted specifically for the quad for which it is ordered. Please provide information in the forms below about any engine/exhaust modifications, how you ride (riding style), and what fuel selection and oil premix ratio you use.

It came out of the box nearly perfect and I was able to make two adjustments during our first practice heats and had it dialed in. HOLY sh*t, it’s unbelievable – extremely crisp through the whole range and I’m able to lug through the tight corners in 3rd gear. Dyno shows my 431cc LED Puma went from 60 to 64 Horsepower with the SC2.

I read every forum online before purchasing a 38mm smartcarb for a 86 trx250r. The bike has 68mm piston, full air box, full fmf pipe. I live in New England and struggled with jetting on an original Keihein carb that was completely rebuilt. Between elevation changes where I ride spanning from 42′ above sea level to other riding areas 2000′ above sea level, the bike always ran like garbage. Humidity and temp changes are drastic here from one day to the next and the bike was becoming a hassle. I bought my smartcarb used, as I did not want to pay full price on something that I have never tried. After putting the carb on my bike, with no tuning once so ever (came off of a trx250r with full pipe and stock motor), the bike literally started first kick. I no longer had my low end bog. I had crisp throttle at all rpm when you whacked it. After several rides at 42′ on up to 2000′ on 90 degree days and 65 degree days, (and little tuning help from this company) the bike is snappy and crisp. I maybe spent 30 minutes setting carb to my liking then did plug chops. I would recommend this carb to anybody with a 2-stroke. Best part is, I contacted this company and spoke with Nathan who is a customer service rep. Even knowing I bought the carb second hand, he went out of his way to give me technical support for carb settings for my bike given my region and modifications. He did not care that I did not buy new, basically said he valued me as a customer of their product regardless of how I purchased 🙂 Customer service is absolutely awesome. The carb auto tunes itself for elevation and temp changes unlike the Lectron. The dial clicker is simple to use and you really do not have to mess with it at all once set for you bike. No more gas leaking out vent hoses either. Super impressed with this carb and the people that work here. They hundred percent stand behind their product. For people online that were not impressed on some of the forums, I feel they did not take the time to set it up properly for their application or did not contact these guys for support. Hell, I even sent my plug chops to them to read and they helped with that. I cannot say enough. Always been a 2-stroke guy as far as sleds and bikes go and did not think I would ever go to this style of carb, but after purchasing and seeing how this almost made my 2 smoker into a “fuel injected” bike, I will never go back to an ordinary carb. Very good product. Thank you again to Nathan for all the help setting mine up! Greatly appreciated the time and effort especially when I purchased second hand! How many other companies would have done that???? Not many!
