those jet kits are a complete waste of money, tell him to return it and get his $ back
they never include the jets needed, 90% of stock carbed bikes require a 250-320 jet, wonder why these do not include those ???
cause it's a F'n scam to sale you all the jets nobody uses and they wasted their $ buying, so pass that mistake onto us ???? crooks i tell ya !!!!
FMF's = 270 - 300max
go to the local dealer and buy them individually, mine lets me return the ones i don't use
start large and plug chop your way down to perfection
