After being on the fence about what carb I wanted to run, the SC2 caught my attention. After reading many reviews, with some positive, and some negative, I decided to give it a shot. I gave them the details on my setup, as well as possible future planned mods. 8 weeks later, it finally arrived, and got installed. The bike fired up on the first kick, and had a nice fat blubbery idle. Even with it running pretty rich, it has great throttle response. It's still really early, and I need to do a little tweaking to lean it a bit. But I will say, out of the box, I'm seriously impressed on how close the "jetting" is. On the east coast, my temps range from 0-100, and low humidity to 100%. Im hoping it lives up to its name. I used a dremel to remove a bit of material from the factory air boot, right at the top where the venturi is, to be sure it was exposed as required. It was a tight fit with the boot, but a little heat, and some choice words got it done. Im not saying this is the carb for you, but it seems to be working well for me so far. Hopefully I can update this post in a few weeks when I get some real time to dial it in.
