Well, I just converted the 7 to race shift and let me tell you, it is soooo much quicker to upshift! A lot more positive too, I think missed gears will hopefully be a thing of the past. Will put up a pic when we can do such a thing again. Just gotta remember which way they go now lol. Already stuffed it once on my round the block 'testing' ride. 2nd back to 1st at full throttle = not good. Many revs.
But it is a great mod, and costs $0. I would recommend it for street bikes too. It is a bit of a muck-around to get it right, including (after much scratching of head) a couple of washers under the rear-set mounts. If anyone wants to do this to a 7 or something similar and needs help, let me know.
