Bro's,
I was given a DynoPort jet kit (the same one that comes with the Toomey T5's) It has some 270 and 280 mains and a set of needles. I dont plan on using the jets, but was wondering if the needles would be ok. I was told that these kits are specific to Toomeys but that seems silly. )Anyu advice is greatly appreciated..

That actually runs well on the FMF, the fmf is just a refined copy of the T5, however here in OH with a an airbox lid we ran a 260 I believe, but needles ran well

I run the Dynojet kit with the FMFs. The 270s are doing well for me with the lid on. Without the lid, 300 mains.
