Large Spur vs. Small spur
Hey Gents,
I'm reading through this thread as I just built a TC6.2 that I bought just a month before the TC7 came out, ouch. I am wondering what the advantage is of a large spur gear vs. a small one. The kit comes with an 87T, yet I have seen some tuning videos with as small as a 72T. I'm planning on racing in 17.5 on a large asphalt track, good grip. Thoughts please. Thanks.
