I've fit a Smartcarb to a 2011, 2014, and a 2018 GG 300. On all of those there was interference for the cases to the float bowl of the carb and it had to be tilted. In doing that, the float height needs to be set lower (in my opinion). I am going to try a carb spacer from an early 90s CR 250 Honda to see if that helps (I think it will).

I would suggest a new cable as the one I tried to use that I already had on the bike did not work. It resulted in a the revving that you experienced as it did not seat properly in the slide. Get the Motion Pro that is 4 inches longer (10-3000 is the part number I ordered). That allowed the cable to seat properly and not get hung up when I turned my bars.

The SC2 that I have on my 2018 300GP has a needle (AQ-07) that is too rich. I have conversed with SC tech support and will go to leaner needle. However, that is my case, for my mods, my style of riding, and at my altitude (my riding typically starts at 7k feet and goes up over 12k feet). Another rider in our group is having the same richness on his needle for similar conditions but with no mods. A third rider in our group has an SC needle that works fine on his 2019 6 Days.

Even with the setup issues, I am fine with the SC. I bought the 2018 used and it had a Lectron on it. It had no power compared to other GG 300s I had and my friends have. That is the knock on the Lectron, no power on the bottom, mid, or top. The SC2 running too rich feels like it has 8 more horsepower.

Good luck and let us know how you make out!
