Mikuni Needle Advise

[Yaxy]

Guys,

 

I am currently running the stock needle (5DP39) on my RZshee with 28 FS Mikuni carbs. I am looking for a different taper needle that will reduce the amount of fuel off idle to about 1/2 throttle. I have adjusted the clip to postion 2 and I may move to position 1. This is an option but I am looking for suggestions on who I may be able to talk to to investigate this further. I have contacted a company who is looking further into this but at first glance there wasn't any luck. The bike runs fine the way it is and I am just looking to fine tune.

 

With these carbs there is only one choice of throttle valve and I think there is only one size needle jet.

 

Current low speed jetting

15 pilot jet: moving to a 17.5. With a 15 I need to have the air screws in all the way.

 

Thanks for your time.
