Rejetting Matrix

Postby Admin » March 31st, 2008, 3:33 pm

Stock pipes (baffles or debaffled) & stock airbox:
128 or 130 main, 30 or 32.5 pilot jet, dyno spring, dyno needle on 3rd notch, mix screw at 2.5 - 3 turns. Adjust idle knob as needed to reach 1100 rpm.

Aftermarket pipes (baffles or debaffled):
132 main, 32.5 pilot jet, dyno spring, dyno needle on 3rd notch, mix screw at 2.5 - 3 turns. Adjust idle knob as needed to reach 1100 rpm.

Aftermarket or stock pipes (baffles or debaffled) & Uni filter or K&N (airbox mounted):
150 or 155 main, 37.5 pilot jet, dyno spring, dyno needle on 3rd notch, mix screw at 2.5 - 3 turns. Adjust idle knob as needed to reach 1100 rpm.

Aftermarket or stock pipes (baffles or debaffled) & K&N (carb mount):
155 or 160 main jet, 40 pilot jet, dyno spring, dyno needle on 3rd notch, mix screw at 2.5 - 3 turns. Adjust idle knob as needed to reach 1100 rpm.

Aftermarket or stock pipes and Hypercharger airkit:
142 main jet, 45 pilot jet, dyno spring, dyno needle (for Thunder kit) on 3rd notch (Thunder says 2nd notch, but no one has had this work well), mix screw at 2.5 - 3 turns, plugged air jet. Adjust idle knob as needed to reach 1100 rpm.

Add the How To (Rejet Carb) from BriMan's website http://www.therusks.com and you are in business.

This should cover the bases except for the Thunder air kit. I am looking for the posts that had those settings.

Oneida Suzuki carries all but the pilot jets which motorcyclecarbs.com carries.

Note: Motorcyclecarbs.com has a rejet "kit" they have put together using the stock needle, with new main & pilot jet. Several members have done this and some are having problems dialing it in. They have no other jets to play with to fine tune and the stock needle makes the bikes less responsive in the mid-range. My recommendation is to use the dyno kit and buy a pilot or two. The benefits outweigh the cost savings and you have the jets on hand to fine tune your setup. [HuntsvilleAL note - I used to motorcyclecarbs.com kit and it worked just fine. The stock needle is re-used with shims. However, using this kit worked fine for me because I had this matrix. Without it I would have been toast.]
