Upping the main jet

[leprogle]

The stock main jet is 95 in a 185s, if i put a 102, and put a k&n in it, do i need to pipe it too, or can i run stock? I have a dirt bike carb with a 102 main jet, i was just wondering if i should make the swap.

Just check the plug after. I would run a new plug in there, then ride it and check it after. REMEMBER, just because you put a bigger main jet in doesn't mean its faster, you could deliver more un burned fuel, hence flooding it.
