yes , I knew about the 8mm kit and with the help of Jim from Sick Bike I ordered it as per his link , here is the strange thing , the kit came with the 8 mm bolts , one was a Allen headed bolt and the other hex head , but they didn't fit the bracket , I had to use a die grinder and enlarge the holes
Will certainly check out your build ----
I was messing around with my build some this morning , the upgraded banana style muffler won't work , a stock muffler fits , might have to do something custom , same with the upgraded head , it won't work , the Sick mount is as far as it can go forward and the jack shaft is 1/8inch from being against the seat post and the 17 tooth gear still hits the tire by just a tad ---- I have a couple of gears ordered , a 14 and a 13 tooth ------------
used the speed chart up above and it doesn't really take into effect the two gears on the foot pedal crank , but with out those gears in the calculation , it has it at 76 mph in high and 44 in low , wonder if it is going to have any low end at all after switching from 17 to 14 teeth ----maybe changing the crank gear would do it justice
