I am wondering if there is a superior brand with Jet kits or are they all comparable? Thanks.

 

I prefer Mikuni, Dynojets are good too, those two are pretty much your choices.

 

I have an FMF kit, but I think they are all the same. Just go with a reputable brand.

 

They aren't the same. Dyno jet numbers mean differen't things than mikuni jet numbers. Example: Mikuni 175 main jet, flows the same as a dyno jet 190 main jet. Mikuni jets are $5 for 2. Dyno jet kits {fmf kit is dyno jet}are $$. Just do a search on what you want to jet, and buy some mikuni jets.
