First real plug chop!

[Fast6hand]

Made all necessary adjustments and leak tested. All is good now. Did a chop as it should be done. What you guys think? Don't mind the hack of the plug, only had a hacksaw available at the time. Man did that suck.

I would say go up 1 jet size

I would say go up 1 jet size

or 2 sizes, hard to even see a smoke ring...
go big and work down !

 

[Fast6hand]

Ok. There's a 310 in there now. Maybe I'll go to a 330 and go down.

 

[harley1-5]

awk I kinda see a ring kinda high and very light x2 on the 2 sizes better to be a bit rich than a bit lean

You bet your sweet bippy!

Alright thanks for the help. I'll post pics with the 330 when I get a chance to do it.

i ran a 330 with LRD no airbox and all that stuff

Well that's good to know. Did you run a 30 pilot as well? You had all the same mods? I'm running a CFM airbox.

 

[Herpderplol]

i had mods close to yours. uni pod filter on the carb and no box though.

i didnt change the pilot jet. i never actually plug chopped with it (sshhh)

i sold it for a DMC. IMO dmc is better. but i had porting and a small carb for low end power, so it was a monster with the low end pipe.

Did you ever glance at the plug?I'm gonna start there. It's funny because when I rebuilt the motor I had a 330 in the carb. The 30 pilot made a huge difference. My a/s is perfect now.

Just an update. Got a chop in today. This is with the 330. I think I'm there. It's brown. No white/grey. May be a tad rich.

 

[Fast6hand]

Oh and I went back to the 32.5 pilot and was able to make all necessary adjustments. Ran awesome today. I really like the timing advance.

That plug to me is one jet size small.

You could go up one size without loosing power, and have the added protection if you ride at slightly colder/lower.

If the engine does not falter with the larger jet keep it?

Colder/lower than Florida? Haha. But I do agree. If I keep it there you think I'll be harming anything? If I go up it will be a 340.

It is only my preference, what you got looks good, one size bigger to me would be better.

I am an avid believer in jetting on the rich side.

Just say for instance you jet at the edge and you develop a small leak at the header, that leak will throw you to the lean side.

Jet bigger, that leak may just be masked enough to save a piston.

Unless your are chasing the podium, and are happy to ride with the pack, jet on the rich side!

Thanks Blaaster for the help. I'm gonna go up one and see how it goes.
