??? is stock sprocket count GT750 1976

[chainsaw]

What are the number of teeth for a stock gt750 1976? You kinda have to slip the clutch on mine and it seems to be geared for highway use on my bike. I may want to drop it down for more of an around town quicker to get on the pipe ride. What would be a good combo of sprockets for that? Who has them and how much can I expect to pay?

Chainsaw.
If memory serves, the stock sprockets were 16 front, and 40 or 43 rear. Quite tall gearing for that engine. Suzuki's attempt to bring up the gas mileage or make it more civilized, who knows. A good all around ratio is 3/1. 15 front and 45 rear. Makes for more brisk acceleration, and still good at road speeds. The sprockets are still available on the aftermarket most places. The rear sprocket fits many, but the front is GT specific. Expect to pay about $ 70 for the pair . If you shim the front sprocket out a bit, treat yourself to an O-ring chain, or better yet, an X-ring one. In a lot of cases, it will be the last chain you will need for the bike. Makes the sprockets last longer too.IMHO. Cheers.

I counted the teeth on mine. I have a 16 front and 43 rear. So, if I drop to a 15 front, how much will that change it? I am wanting quicker throttle response. It seems really sluggish on the highway in 5th. Almost like bogging down until I get the rpms up. I wont be riding the highway a lot so I want it snappier.

Would I go smaller in front and larger in rear to get that?

If highway use isn't a priority, then go with stock gearing for a J model ( 15 front, 47 rear) and that should wake up the performance of your steed. If your chain is at all worn, then I highly recommend changing it as well, as a worn one will reek havoc with new sprockets. Wait until you can spring for all three, and you will be very satisfied with the results. It is a water buffalo, after all. Cheers.

actually my chain and sprockets are all in almost new condition. Where would I get the sprockets from?

[Buffalo-guy]

Sun sprockets, or PSI are two that come to mind. Any shop that has aftermarket catalogues should be able to point you in the right direction. A lot of GS Suzuki's used the same rear sprockets, but the fronts are GT specific, different spline. Are still readily available. Good luck with it. Cheers.

There's a handy dandy gearing chart at http://pinkpossum.com/GT750/GT750%20gearing.pdf

Changing from 16/43 to 15/43 will raise rpms at 80 mph in top from 4400 to 4700. which should help a little.

On a stock motor with peak power at around 6,500 RPM, top gear should theoretically pull 118 MPH on stock 16/43 and 111 on 15/43

awsome chart TZ. thanks. I think I am going to keep the 16 and go with a 47 rear when I get the money.

I use a 15/43 on my stock 76 Buffalo, it works ok for me and i like how it feels, your results may vary. The problem is the stock pipes seem to have a sweet spot around 4000 and higher, so under this rpm figure in fifth gear on an average mountain grade road grade and the bike lags a bit.
