[mud runner]

and i opend the transfer ports like in kens vid and are no toil air filters better than stock

 

[dksix]

I suggest picking up 270-310. I've got a full DG, no lid and I'm stock inside. I'm at 280 on my main.

 

[Awk08]

/\ yep, just start large and work down, doesn't hurt to have some bigger jets on hand for any future mods.
plug chop to confirm each.
yes...no-toils are better than the stock filter

 

[mud runner]

I strongly recommend that you do a leak down test on your motors as a #350main seems huge.

A reed spacer or reeds should not change jetting.

 

[mud runner]

A reed spacer or reeds should not change jetting.

i.dident think the reeds would make a diffrence but dident know qbout the spacer
