Disband the pipes and pods effort?

[red1100]

In late 83 I took off the black pipes and airbox and did pods and 4to1. A Yosh at that time.Now at 67yo I’m thinking about going back to original. Strictly because of noise. I wear earplugs now and it helps some. So here’s my dilemma, I figure out a way to quiet down the Vance and Hines and pods a lot without upsetting the carbs, or go back to my black pipes and airbox for which I can’t find the original jetting numbers for. The easiest thing to do would be rewrap the exhaust core but I’m not sure it would quiet it down that much. The pods seem to make more noise than the pipes. I’ve already scared the heck outta my self with the power zillions of times so that’s not the issue any more. Ideas?

I know there's a spreadsheet floating around here somewhere that lists every GS, their Carb models, and their stock jettings. Or, if you list your specific bike info: Year and model, someone who knows may post the answer. Consider putting the bike year and model in your signature. Then you'll never forget to post it, and no one will have to ask.

Take a look at the parts fische, for my bike the original sizes are listed.

Personally I wear earplugs because of the windnoise not the exhaust / intake noise.
Back in the day, I did find that the short exhaust like the V&H did make for more noise in the helmet VS my current Yoshi that has a much longer can that runs to the back of the bike.

I would think that finding stock jetting #s shouldn't be that difficult.

I know after you've restored the intake system to OEM, you see better mileage.
You can find a Db reducer insert/baffle for your can on ebay, repack the can or buy a new muffler.

You can find the jet sizing here - http://members.dslextreme.com/users/...at_height.html

Wind noise is a lot of it and somewhere online recently I saw a product that is some sort of noise reducing filler between your helmet and body. I’ll look that up today.

or go back to my black pipes and airbox for which I can’t find the original jetting numbers for.

Your service manual should supply all of the OEM carb settings.

Gads! Didn’t even think of that and it’s right on the bookshelf in front of me. Thanks.
