33 pwk jetting question

[TeamRealtreeHD]

Yes... both silencers have oil coming out, and the plugs are wet on the threads. But not inside.

 

I am mixing at 32:1 or 36:1 everytime I mix 5 gallon. Kevin doesn't want me to go any leaner than 36:1 on this motor.

 

But even when I ran the bike lean on the jets it was the same way. So it's not a rich jetting issue

[TeamRealtreeHD]

Anyone have any ideas? Or any input on the octane being too high for 185 PSI? Causing the low end not being there?

I am going through the same things. Just put the new ported motor together with PWK 33 s and have the same problem. I will try the change of octane. I have jetted and jetted and still have it. I have changed the stator,reed cages , reeds, intake, coil , and cdi with no fix. i have put different carbs on that are jetted for the same motor and no fix. Fuel octane could make sense.

 

 

let me know what you find out. I will do the same

[TeamRealtreeHD]

What domes are you running, and what is your compression? That will tell you what gas you need to run.

 

We took my pickup coil down to .016 and gapped the plugs to .020 insted of the standard right out of the box gapping.

 

I am running 105 octane and it plain out rips now.

I have 18cc noss domes with 175comp +5 timming stock stroke/bore with passion 12 port dunes drag style will CPI style inframe drag pipes.

I had straight 112 fuel and mixed a gal of 89 with 2 gal of 112 to see if there was a difference and the bog got way worse and the plug were really rich. I am going to try a different coil and cdi box today.

 

But it does sound like you have the same problem ..... Is yours fixed?

[TeamRealtreeHD]

Yes, mine is fixed.

Hi What did you do in the end to sort out your problem?

So what carb settings did you finally end up on please?

[TeamRealtreeHD]

160 mains run a little rich on her... I switched to 155-158's, currently have 155's in for the drags tonight
