DRZ400E + Yoshi SS rejet?

Recommended Posts

Hey Eddie & others,

I got a great deal on a Yoshimura slip on (I know, the Titanium full system is the way to go, but I don't have $700).

Anyway, I'm wondering what jetting changes I should make when I install the pipe? Is it worth it to buy the JD kit to get to most out of the pipe?

Currently I am running the following:

165 main jet

pilot fuel jet 48

fuel screw out 2.5 turns from closed

needle on 4th or 5th clip from top on stock needle

snorkel removed

exhaust end cap drilled out

about 1500ft above sea level

I also did the Taffy and o-ring mod but still want some more low end torque.

Thanks in advance
