wooshing sound 81 gs750

[Larry D]

Are you sure?
I thought it was the 8V 750 that were sold as shafties in Japan.

UHhmmm......you could be right about that. I know there were 750's sold with a shaft, but, I can't recall if they were 8V or 16V or both......in any event, I doubt the OP has one......unless he brought it from Japan.

I believe it was only the 8-valve 750s that got the shaft, and they did not make it to '81, so it's rather safe to assume that he has a chain-driven 750.

The question remains as to whether it's an E or an L, but for engine work, it does not matter.

The carbs have been completely torn down and dipped overnight in a can of berrymans and have had the new o. Rings from cycle orings installed. As per the pdf of how to clean and adjust the carbs. And ill try to get a picture up as soon as I can

[Pendulum]

Cool, I'm betting it's either valves or air leaks.

We get a LOT of folks on here that do a half ass job with the carbs and claim that they're cleaned "real good" which is why we ask. Thanks for clarifying.

[Larry D]

....and to be clear.....I hear "whooshing" sounds on my 750 too.

........usually between about 85 and 100 mph.......


Good luck with your 16V 750, they are a blast to ride !!!!

Oh c'mon, Larry, that is just the sound of your head expanding.

[bartmancometh]

this is what it looked like when i got it




and this is what it looks like currently turning it into a cafe

Did you install a jet kit when you switched over to the pod filters? also the air wooshing sound you are talking about may be the sound of air being sucked in through the pod filters. You WILL need a jet kit with those filters. Oh and your bike is an E model

[bartmancometh]

i did not put the jet kit in. what kind should i go with? and thanks for the id

[Larry D]

No idea on what jets you'll need, but you're using much, much more air than if you had the stock setup. These bikes are very particular on the air/fuel mixture.

You're bike looks like a mix to me because of the leading front forks. Perhaps it had a front end accident at some point...

Do you still have that air filter box that's laying on the floor in those pics ?? If so, I'd be interested in purchasing it from you.

[bartmancometh]

no i sold all the extras already.

The 80 and 81 750Es had leading axle forks.

The 80 and 81 750Es had leading axle forks.

The 1100Es also had a leading axle for those years.

Dynojet is the most common, followed by Factory

[koolaid_kid]

Get the DynoJet Stage 3 kit. It contains jets for bikes with pods and bikes with pods and pipes. The needles are also an important part of the kit, some say the most important part.
