Checkin in, first post... here at least

[Bear45-70]

I just pull the bowl on my brand new never been installed OKO 26 mm carb and the float is 19.25 mm, so 19 should be a good number. Oh and all the OKO - PWK carbs use the same float bowl parts, hence the float setting is the same.

That is how my 86cc ran .....with that filter on.

What is the jetting now?

Ha I knew someone was going to chime in about that filter. I'm at 50 pilot and 155 main. I just ordered a set from scooter assasins on fleabay which will give me 158, 160, 165, 170, 175, 180

I'm thinking one step at a time, shouldn't my ideal temp range be under 300?

Your Ideal temp range should be 300-375
Try taking that filter off and see if the problem gets better or worse.

I know you really like that bling bling

I appreciate it, I will pull off the carb tonight and get some measurements after I do these ribs on the bbq

every time I ride around the city... bling bling. Once I have this float bowl measurement figured out thats the next variable... either that or the main jet needle clip position

to many d*** variables!!!

[Chicago Ben]

so I measured my floats according to mystic's guide and I was pretty d*** close to the 19mm bear's stock 26mm is at (weird eh?) ... I bent them down just slightly. reinstalled- same issues, maybe slightly better? (could be in my head)

just to make traffic happy I ran the bike without the air filer-

results... same.

It's starving for fuel I feel like even at 160 main. Hopefully my package from scooter assassins comes this week with an assortment of large main jets.


On a side note- I broke my d*** plug cap. The piece literally shattered. Who sells good aftermarket ones? VT?

[Trafficjamz]

why do you think it is starving for fuel?

Is it possible you are going in the wrong direction?

Maybe it is too rich. What jets have you tried so far?

I have no clue why its starving. When I reinstalled my carb today, I kicked the bike over once and watched the float fill up rather quickly so I know there is no issue with my fuel lines or vacuum. The bike idles great, it doesn't even smoke really either with 32:1.

I started at a 155 main and now I'm at 160. I just have a feeling that it's all air an no fuel at 1/4+ throttle by the way it BOGGS.

When these new jets come in I'm going to put a 175 in there and see what happens I guess. Better to be too rich than too lean and blow this up anyway.... right?

[Bear45-70]

So raise the needle but feelings just don't get the job done with novice tuners. If it is crapping out at 1/4 throttle, run it there for 10 seconds and do a plug chop. Read the plug and it will tell you whether it is too rich or lean. You do not have to run at WOT to do a plug chop, if your problem is else where do the chop at the RPM.

[Trafficjamz]

But if you are way too rich the bike won't run.

My 86cc bike with a 30 mm carb was jetted @ 52 pilot 135 main needle 1 clip up from middle and air fuel screw 1 3/4 turns out

your 155 main in a 26mm carb makes no sense to me.

That has too be rich. And now your ordered even bigger jets

I think you are going in the wrong direction.

Do you have smaller jets?

[Trafficjamz]

You do not have to run at WOT to do a plug chop

I did not know that
I learned something today.

All I know is that this is cutting out majorly...

I believe the needle position 1 clip up from middle is the 'stock' position on these oko carbs, if I'm correct on that, that's where I am because I have not moved it.

Maybe I should drop down and see what's going on

In my current bag of goodies before these large jets arive I have sizes 112 (stock in the 26mm oko) 140, 145, 150, 160 (in the carb now)

Maybe I'll throw that 140 in there and see what's up

[Trafficjamz]

I suspect 130 or lower is needed.

Here is a good pack to get

Greetings:

Corsa-festooned Flash 3.26 has a 125 in it now. I suspect an 86 might need a little more, but not that much more. Tuning woes sometimes foretell vacuum leaks. Any seepage at the head, base or pipe gaskets?

[Chicago Ben]

you guys are probably right, I'm probably just flooding this bike

[Chicago Ben]

wheelman- your original recommendation to me, along the lines of 'start no lower than 150-155 main' , for a starting point one would just go down from there correct?
