Hello Erbman, good to hear from you.
I haven't had much time to mess with it, but that kind of was my plan. I still think I have a vacuum leak sneaking in on me, just haven't found it yet. As far as riding temps, we get plenty of 70+ days here during the winter so there really no off season.

Everyone have a Merry Christmas,
and stay safe out there!

If you still have the stock igniter (ECM) I’d throw that on there to eliminate any spark gremlins.

Lets make this real simple. If it's winter, and you can't ride bike to bring it up to normal operating temps, won't be able to do final tuning on pilot screw and idle control knob. Then wait till spring.
This should get you near the ball park tho
Baron needle, 4th groove 1 washer and the spacer.
main jet 170 or 167.5 mikuni jet
stock pilot jet 35 mikuni
set pilot screw at 2.5 turns out from a light seat
Turn in idle knob 2 turns, this will increase idle speed and make for easier start for new set up, will re-adjust later.

pull choke all way out, start bike, if idle excessively fast, turn idle control in a little bit, just a hair to slow it down since the choke is also causing a fast idle, but final tune on idle control has to be with choke off, and has to be done with a fully warmed engine If you can ride, depending on temps, can be any where from 15 mins to 30 mins to bring engine temps up to a minimum 140degs (oil temp) Keep in mind, the only way oil gets heated is by friction of internal parts, takes longer than most people think to heat 5qts to 140

Any way, my 3 cents
use to be 2 cents, inflation brought it up a penny. LOL


We quit using stock pilot jet size a long time ago. Testing has shown that a 37.5 works best on a 1600 and a 40 works best on a 1700. And 2 1/2 turns out is good on both 37.5 on the 1600 and 40 on the 1700.
