04/2021 tbr7
I recently purchased a 04/2021 TBR7.
I am looking to upgrade the carb, plug and sprockets right away. I was thinking of going 17/42 or should I stick with the stock rear? This may be a stupid question, but I have seen several postings about the newer 2021 TBR7s have different sprockets and chain. Any help is appreciated. Thanks |

So I have read it has a 12/38.
I'm trying to increase my top end, but not loose all of my torque. I've read that 13/32 doesn't really have enough rpms to get in 5th gear. This is not what I'm looking for. What would a better solution be? |
