I have read many places the TW37 tops out at 9.8:1 , does anyone know what the TW26(G)s optimum compression ratio is ? I saw Bill Bishop using 9.25 on his Stage II . Thanks to all in advance
it ought to be fineLittleBear said:Okay guys, if I run a 26g with 9.3:1 compression on a 95" motor on a carbed bike, can I use the stock ignition module or do I need to to get one that retards the timing say 5* to avoid pinging with 93 octane gas.
Thanks in advance for you replies.
