28 OKO needles...please help

[Ndog1]

Guys...I have JJL, JJM, JJN and JJQ needles.

For the past month I have been switching them and varying clip positions.

I have a SR50 aprilia w EVO2, yASUNI C21, 28MM OKO,
vl REEDS WITH KIESLER WEDGE AND STOCK IGNITION.

I thought the JJL at leanest was ok but then as it got warm it got thick in the midrange again. Im to a point where I am lost and cant tell the point where I am going to lean, as running like poop in the middle seems very similar for both overely rich and lean conditions.

Ive read many of you with this setup...if someone could just give me a place to start. My fingers are literally blistered from tuning all day every day.

Thanks

If I can give you my advice from past experiences... Ditch the OKO. I had one and did get lucky and found the perfect jet/needle setting/air setting in a short time. But the carbs are not the best of quality...

As they say "you pay for what you get" If you are interested, I have 2 x TA-09's for sale and one 28mm version soon if you wanted a nice carb

Regards

Butch

i have been running both OKO & Keihin PWK28 carbs with JJH needles & they are spot on.
