Jetting help

[banshee#527]

Working on getting my banshee running again. Its been sitting in my garage for 6 years. Switching up from a Trinity single carb setup to dual 28mm keihin pwks. Engine is stock. Got some new SLP pipes, K&N air box lid, 1 SLP 2 inch flow rite for the air box. Going to upgrade from VF2 to VF4 reeds. Anyone give me a base line for jetting? Riding around 500 feet above sea level

i would start with

48 pilot

jjh or n68a needle

145 main

[banshee#527]

Cool. I'll order some jets. Have the jjh needles already.

[banshee#527]

Forgot to mention that I have +3 timing advance. Will that effect my starting point?

Alright so I finally decided to tear down my shee and build it this winter and its comin together pretty well and i need help in knowing where to start with my jetting the mods i got are...

 

Power lid k and n filter and another k and n filter in the box

28mm pwk carbs which is where i need help

4 mill 115 long rod

hardcore mx port job from herrjugsracing

20cc domes cool head

dmc 916s im planning on buying next week or should stay with fmf fattys

pump gas 92 or 93 octane 32:1 amsoil

 

Btw this is my first post on here ever if i did anything wrong or posted this in the wrong spot. my bad

[banshee#527]

Would running a dual feed Pingel be too much for 28mm carbs?

[lastnline75]

Nope.

Just realized that my carbs have different sized fuel inlet nipples. One is for 5/16 fuel line the other is for 1/4 line . If I reduce a 5/16 line down to a 1/4 line will that throw anything off being that 2 different sized lines are feeding my carbs?

[sleeper06]

Should be 1/4 on both , change as a pair with same line

[banshee#527]

Picked up some 1/4 fuel line today. Bit of a tight fit over the one carb and pingel but I guess theres nothing wrong with a 'tight fit'

 

Thanks for the help.

[banshee#527]

Well I finally got it running today. Got a bit of a bog off of idle. Wants to stall out when letting the clutch out unless I keep the revs up. Running 145 mains, 48 pilot, jjh needles with clip in the 3rd position, air screws are 1 1/2 turns out.

 

Pulls hard once it gets past the bog.

[banshee#527]

Using Maxima castor 927 at 40:1 with 93 octane.

 

Should I start by adjusting the air screws?

[banshee#527]

Does this seem like the pilot is rich?

[banshee#527]

Finally seems to be running happy. 145 main, 48 pilot, moved the clip to 4th position on the needles. Don't have the real estate to do a proper plug chop right now.
