1982 GS450 Exhaust??

[Guest]

I want to cut my exhaust and and some shorty mufflers like the ones in the link below from Dime City. There is a piece that connects the left and right exhausts. Can I cut before the connection eliminating it or will that cause any issues?

No issue at all...I have a similar setup. I assume you will be jetting the carbs?

Yes, I would like to run pods and change the exhaust like yours. What jets did you have to run?

Also, what handlebars are you using there?

[Thumper88]

I have K&N pods and the slash cut mufflers are pretty much straight pipes.
I purchased the Sigma6 jet kit off eBay
Spaced the needle, drilled the slide holes, upped the main jets (I think 122.5), and finally I had to up my pilot jets (20).

Superbike handle bars..they rock.

You'll have to explain what you mean by spacing the needle and drilled the slide holes

[Thumper88]

The kit explains most of this, and includes the drill bits/washers...but effectively you drill the slide for a snappier response (allows more air for quicker return on the vacuum diaphragms that raise the needles). You use a smaller washer than the stock washer to raise the needle for a richer mixture.

In search for topics talking about these two mods, I am now curious, it looks like Pete has found some adjustable needles.
EDIT: Was not aware of a Dynojet kit (3113)...says 1983 only...

So, looks like 83 carbs are completely different:

Looks like rapidray may be able to provide adjustable tapered needles...that would be something to look into...

What size pods did you have to get? Also, were the jets you needed in the Sigma6 kit?

[Thumper88]

K&N RC-1822

Pilot jets were not included in the kit.
