ptr jetting

[NickisGod]

my mods are as follows,

 

paul turner mid range pipes

+4 timing on a 200w stator

39mm carbs on a crossed over intake

dual exposed 12inc air filters

coolheads

vforce reeds

runs on 5 gallons of 100 octane and a quart of yamalube

 

it runs great but i had the setup tuned for t6 pipes, and i think i should change the jetting?

 

what do you think?

you are probably close, maybe down a size in the main, but let me tell you, imo, those carbs are just plain too big. there are guys with +7 mill strokers running 35s fine and you are stock running 39s..... just not going to be very efficient.

lets say i found the carbs before i found this site :/ ..... so ya i know i gotta find a better carb setup, but alright thanks

hey, no need to get pissy, i didn't say anything snotty, you were asking for advice so I was helping out. reason I brought it up is because you are going to be jetting them and being that they're probably somewhat inefficient, they're not going to jet as consistently as say a pair of 28s or stockers....

 

i'd keep what you have in there, main jet wise and see how it does; should be close for a start.
