2003 Honda CR250
Install:
Throttle cable install was much easier than the factory carb.
Fitting the the air box was a bit of a b****. But it sucks with the factory carb too. I didn’t need to trim anything, it’s just a little longer than the original. Wedged golf balls in between the farmer and the boot on the left side, while pushing from the right.
Jetting:
It was really rich from the factory.
I had to adjust the float bowl, no big deal.
I’m probably 15 or so clicks out from where it was when I got it. Starts good no need for a choke, I’ve done 3 spark plug tests all look great!
My bike is running very well. Less smoke, not loading up. Honestly it is running ??!

I can’t believe it, SC2 makes my old CR250 run like a new BIKE! awesome! I decided to buy a 40MM SC2 for my brother to revive his CR500!

Hey guys I bought this for my 2003 CR250R. I wanted to let you guys know that this carb is absolutely the BEST product I have ever bought for any of my bikes. I recently talked a friend into getting a carb for his YZ125 and will continue to share my experience with others. Customer service is excellent, and the product is phenomenal. The 38mm SC2 SmartCarb is worth every penny times 2. Thank you for making such an excellent product.
