OK, I want to go to 8 tooth drivers so I can run my 1175's. I put about 500 miles on it with them in the track and its scratching the bulkhead pretty good when the front compresses. Theyre not hitting anywhere else, so I was thinking Ill just go to 8 teethers. How the heck do you figure out the gearing change? Ive got a 23 T and a 37 B gear right now - works out to 1.61 gear ratio on the gear calc with a theoretical top speed of 113mph (spinning 8700rpm with 9 tooth drivers)
Im confused about changing the gearing to compensate - If I dont change anything it said my top speed would be like 80 or 90 something. But I assume it would pull hard and get to those speeds like right now! Id like it to pull that hard but Id like to be able to hit 1teens to 120 or so as well.
I dont know if Im using the calculator right on Yamahainfo.com or not it tells me Id have to go to a 1.4 gear ratio to see 118 and a 1.5 ratio would be 110, If that sounds right I dont know what gear to change even or would I change both? Im just all confused, especially when I try to make sense out of the gearing section in Olav Aaen's clutching book - specificaly about gearing taller for drag's and it not hurting acceleration in light high HP sleds, well I wouldnt call my sled light but it is high HP, so should I go a little taller but not to much?
My underlying motive is to have a starting point to perform halfway decent in the 660' range.
Any input is appreciated and maybe I should just put shorter studs in after reading back through what I just typed?!
