Hello All,

recently purcahsed a bike and not sure what exactly has been done to it in the past. Thus, I am doing a complete overhaul.

the bike has to 4to1 Vance and Hines exhaust.

Now the age old question, it seems, is: what size jets should i get?

105 main
20 pilot?

ive never gotten a complete answer and am not sure what will work best.

again not sure whats done to the bike and want to replace the jets while i have the carb assembly off.
