1979 GS 750 WHAT IS STOCK SPROCKET AND CHAIN SIZES

1st. - NEVER change sprockets without changing the chain..and vice-versa!! - they need to be replaces as a set...they wear our almost equally.. ie - a worn out chain will wear out new sprockets... A new chain will get stretched out by worn sprockets real quick!
Its east to tell what you have...

• OEM sprocket size: 16/43 - 2.68 ratio.

1. Count the teeth on your front sprocket.
2. Count the teeth on your rear sprocket.
Compare yours with stock(OEM)..
Now, if your sprockets match the stock sizes - count the number of links in your chain...(count the inner links).
If the sprockets are different sizes you adjust the chain by that number using inner links. - Usually people go smaller on the front or a larger rear.. this increases the ratio to give a quicker take-off - (more acceleration).
15/43 = 2.86
15/44 = 2.93
15/45 = 3.00
15/46 = 3.06
..when you get a new chain... better to get one a couple links too long than one link too short!!
Your local dealer will be more than helpful!!

The stock gearing is 17T sprocket front and rear is 41T sprocket. Chain size is a 525/122. Hope this helps you out

on that bike your options are probally going to be few.. for the shocks you want to go with something inexpensive no need to get a fox shock. just get a regular coil over.. tire, I live by dunlop, I am sure they have a good tire and do get a good one, cheap tires dont last as long.. chain and sprocket, you can probally get a kit a package deal again your options will be limited but just make sure you get an oring chain it will last alot longer mabye DID or RK

I have a 1977 GS750 and I found that the valves begin to make noise when the valve shims need replacing. You might see if this is similar in your manual for your machine.

You are dealing with Suzuki vacuum carbs, you cannot just replace the air box and re-jet. What you are running into is there is no pressure to raise the diaphragm because there is no restriction to create such vacuum. Either put the stock box back on or go to the biggest main jets you can buy. Sometime even when you get stage 3 jets you still have issues. Vacuum carbs are not made to run with no restrictions.....putting aftermarket exhaust on it will make things much worse.

check your oil. check to see if your front sprocket nut came loose, or anything else on that side.
