Jetting question RZ350

Re: Jetting question RZ350
Your getting there with the pj. While in neutral, blipping the throttle near 3000 or so the bike should return to an idle rapidly if your there/close. If not your lean.
DoldGuy, the advantige using the banshee parts one has choices you don't have with the stock needles.

Changing mains will only affect 3/4-WOT.

Returns nicely to idle after a blip at 3k so guess I am close or richmkane wrote:Your getting there with the pj. While in neutral, blipping the throttle near 3000 or so the bike should return to an idle rapidly if your there/close. If not your lean.

Re: Jetting question RZ350
Opened airscrews half a turn and no discernible difference in the ride. On to the needles tomorrow night.

Re: Jetting question RZ350
The engine should rev up really crisp if that's what was needed.

Re: Jetting question RZ350
Nope. Not crisp. Will drop needles and see what happens. Thanks to all for advice.

Re: Jetting question RZ350
Dropped needles and is a little crisper. Need to take for a decent ride as soon as it stops bloody raining.

Re: Jetting question RZ350
Went for a spin. Still very unresponsive below 3k. Open throttle at 3k and it is flat just like sucking air. Actually will not pull away below 3500. . After 3 k smooths out, slight flat spot at about 4500 but hardly noticeable. Pulls strong to redline after 5k. Here is a pic of plugs after I rode about 3/4 a mike home at about 3k and cut engine as I pulled in.

Re: Jetting question RZ350
IMO those look fine. Maybe your asking to much @ 3000rpm. Are you snapping the throttle open down there or rolling it on. I don't thing anyone's RZ is going to respond favorably whacking it open @ 3000. I would put in a bigger pj and open up the air screw's.

Re: Jetting question RZ350
That thought crossed my mind but the inability to pull away below 3500 leads me to believe something still not rightmkane wrote:IMO those look fine. Maybe your asking to much @ 3000rpm.

Re: Jetting question RZ350
Think you may be right on the pj. Had been thinking I may have gone too small at 20. Cheers

Re: Jetting question RZ350
With some help from my new buddy, iron, some progress has been made.
Currently running
410 mains
DJ needle 2nd clip from top
Airscrews 1 turn out
Is now rideable and doesn't need a bunch of revs and clutch slipping to take off. Will make some more rides when it gets warmer and keep checking the plugs and adjust as necessary.
Thanks to all.
