My bike is going to require some re-jetting this year since I've made more changes than I can count to the engine and exhaust.
It's not that jets are expensive, but it can take a couple rounds of changes before you get it dialed in.
Unless you have a stock on hand, at 20-30 bucks a set (4 jets needed per set) it can get expensive before you dial it in properly.
The jets themselves seem pretty simple:
OVERALL LENGTH = 9mm
HEAD DIAMETER = 8mm
THREAD DIAMETER = 4.9mm
THREAD PITCH = 5.0 x 0.7
They're basically a restricting orifice and it's made in nice simple brass.
I can't see any reason why I can't turn out a bunch of blanks and then drill out to size.
Anyone ever done this job before? Anyone see a reason why I should buy them instead of make them?
