Do i really need the hrc jet kit because 100 notes seems a lot for some needles emulsion tubes and jets of which half i'm not going to use.
So i was thinking of just putting different mains in when i mod the airbox, is this feasable or am i just being a tight arse?
And now for the horror question
what size mains would be a good start for a modded airbox lid and Tyga pipes, and please dont say start big as what is big as I'm pretty sure 190's would be a tad rich 
and I have never jetted anything in my life so I dont even know how much difference one jet size would make.
