jetting?

[blasterkid1998]

well guys i ordered a right bend pipe off of egay a few days ago.and i was looking for some suggestions for the jetting to get me in the ball park. at the moment im running a 320 main with the needle in the middle position with mods in my sig. im at about 1000 feet of elevation and its 85 degrees with 90% humidity. thanks in advance

320 main sounds pretty big for the fmf

have you leak tested and/or plug chopped?

if needed, i have a genuine mikuni jet 310 and 320 that i could send your way. i have no use for them

yep i leak tested last week and i plug chopped with the 320 and it was a tad on the rich side.and i have plenty of jets but thanks for offering the 310 and 320

I'm running a LRD. I have a 330 main in there with needle on middle clip. It's about perfect, may go up to a 340 to stay safe. Sorry I didn't look at your mods.

I would run with the #320 if the plug chop showed a tad rich.

you dont think i should increase the main jet size going from a fmf to a right bend?

 

[Blaaster]

It will depend on what a plug chop says, often a right bend will breathe the same as a lefty, the difference being where the power is produced.

I am not too familiar with the right bends, but on reading they seem to have similar jetting requirements.

In some cases the left bends seem to need larger jets, I believe the Toomey B1 is thirsty, as is a DMC.

ok thanks. im just wanting to get in "the ball park".and i am not familar with the right bends...yet.

 

[Blaaster]

If in doubt, up the size a couple and plug chop back.

 

[blasterkid1998]

well i believe the largest jet i have is a 320.so ill put that in and plug chop when the pipe arrives

 

[blasterkid1998]

i will probably order some larger jets up to about 350. i am only going to run my bored stock carb temporally until i find good pwk28 or larger carb
