(83 heritage special if it makes any difference) Wondering if anyone can help me understand the job of the pilot jet, and what are the effects if it is too big or too small. Ive got open pipes and pod filters, and have been playing around with the jets since the mod. I did have all 3 jets bigger than stock, and after some trials ive put the main and air jet back to stock and it is running omost where i want it. Just wasnt sure if a final tweak could be in switching out the pilot jet to a different size. Any info would be great, Thanks again guys!

the pilot jet is starting and low speed idle most problems are, to small (hard starting) to big (prone to flooding)
