need help with carb

[bigred85]

i have a blaster, i do not really know what year but it is bored 80 over, port and polished, and has boyesen carbon fiber reeds with a DG header and fat boy exhaust. what size jets should i be using?

if you have the airlid off i would start with a 300 maybe and do plug chops until you get it right.. that is if its the stock carb. also the dg isnt the best pipe for the blaster.

ok the air lid is still on. but what does the plug chop do?

 

[bigred85]

also it keeps burnin up plugs, what ratio do i need to mix my fuel?

Been here before, a plug chop will tell you if your jetting is correct.

32:1 is what you should be running.

If you are using a b8es plug and it is burning up, you most certainly have a jetting issue, or a major air leak. Do a leak down test.
