well finally finished off project motor (only taken 5-6 yrs) and is in bike ,with the high ratio gears found at 3000 rpm doing 100kph (60mph) 4000 rpm- 120kph (with carb tuning should go better) with 17/34 sprockets so I'm taking off the hi ratio gears until the motors run in and I can fine tune the chain sprockets to suit ,now the question is what combination would best suit ,not after massive top end speed that I wont use but a improvement over original gearing where the cam can cut in (deidens,same as megacycle 230-30) go 17/36 or 18/36 or does anybody make a 35 rear ,yep I know theres a chart with all the info on sprocket ratios but not much good at it reading properly (for a on road bike)
