50 to a 70 jetting ??

[skyeryder]

How much should I expect my jetting to change right now I think I have 42 pilot and 105 main. Anyone that has done this please chime in, also it's a/c
also gonna need a new coil any suggestions???

Well I have to say that when we switched to 70 from 50 (ported stock 70 l/c cylinder and stock 50/70 pipe) we ran it w/ the stock carb and the biggest jets we have (48 pilot - 115 main). We then went to a 24mm Keihin and HUGE difference!!! It did run quite well w/ the stock Sunworld but definatly worth changing ,and for the prices G-FORCE charges youll be glad you did too!!

thanks, we have a OKO 21 probably gonna stick with it for alittle while. What coil do you recommend, a rock or something must have hit ours the brass piece came out and won't tighten up on the plug or make a spark anymore, these things always happen on a friday before a national when there's no way to get parts:(
