Starved?

Haha. I didn't measure the backpressure, just remember reading it somewhere.
I also had a hunch it was rich when my eyes started to sting. lol.

Anyways, I put in the 124s and now everything runs perfect!! I just got back from a nice cruise on the freeway at 70-80mph. =D

Well you got some guts riding in the weather we have had.. need a new helmet, boots and gloves before this spring. I work graveyards so I do not see the sun much these days ...least what we call sun in seattle

Good to hear you got it sorted out though

Hey, If you don't ride in crappy weather in Seattle... you won't get to ride at all! I prefer riding at night too, there's less cars on the road to watch out for.

Another update, in the hopes that it may aid someone else. I just moved the clip on my needles down a notch (towards the pointy end) and I no longer get any more bogging down at any point in the throttle. Runs grrreat!

Recap:
-mac 4-1 canister exhaust
-cheapo pod filters
-dynojet stage 3 kit
-new petcock valve

carb settings:
+clip on second notch from pointy-end of needle
+124 main jets
+1.5 turns out on air screws

Thanks for the update.

What jets and which notch on the needle did you use?

I used the 130 jets in the kit. Clip is on the 4th notch from the top with two washers below it. Was considering lowering the needle...

Why the washers under the clip?

The washers keep the needle a little higher I believe.

They don't. They just add a little spring pressure. Since the needle is pushed up into place by the spring, the height of the needle is determined by the clip and what's above it.

Update: Installed new petcock. It definitely fixed part of the problem, it no longer starves out and runs quite a bit smoother. However, it still stumbles and hesitates a bit at high speed. ... I'm probably running too rich with the 130 mains. I'm going to switch to the 124s and see if that helps.

So, in summary, you leaned out the upper end with the 124 main jets (those are DJ numbers, right?) and richened up the mid range a bit by lowering the clip, which raises the needle. Did you tweak the "air screws" (they are really "idle mixture adjustment screws") for highest idle speed or just set them and forget them?

Had you read the plugs in any of this process? Doing plug chops to read the color of the plugs would have told you what the engine is doing, might have saved a bunch of time and aggravation.
