1977 Suzuki GS 750 - Page 3 Questions & Answers
I JUST PURCHASED A GS 750 AND THE MOTOR WAS SPRAY
Use a small amount of paint thinner and a stiff brush. If you make sure and wash off the paint thinner when you are finished it should not harm any unpainted items it comes in contact with. If you choose to leave the paint there it won't affect your cooling much unless it was put on so heavy that it blocks the cooling fins on the head (pretty unlikely).
My gs 750 was running ok, but now it wont start
Do the following test:- (1) check if theres sparks at the spark plugs, (2) check if the spark plug/s are getting wet with gas.
If the plugs have fouled up i.e. turn blackish due to too 'rich', you better replace them and retune the engine.
Check the valve clearance and adjust accordingly and also go thro the air-mixture screw/s ...tighten them in slowly being careful not to tighten them too hard to the last to avoid damaging the tip of the screws.
Try to start the bike's engine ...it should start taking into account tht its now got a new set of spark plugs and let it run to some good temperature thn set the air-mixture screw/s:-
release to 2 and half turns (turn outwards).
From the sound and the running of the engine you would know if its at its running ok ..you can however go in or out + - a little to get good idling of the engine ...go for a spin and recheck the spark plugs to its condition and offcourse for the starting issue if its solved.
Hope this helps!
Clip-ons to fit a 1978 Suzuki GS 750
If i were you i would not do this mod. You are going to end up with a ugly top triple tree. Rather find a lower set of bars off another bike. They are all the same diameter tubing.
Wont start
Hello;
If it starts with ether then you have spark, compression, and air. All you need is fuel. Make sure that you have fuel at the carbs and that the fuel is flowing to the cylinders. Check that the petcock is open and free of debris. Hope that helps;
Thanks;

2nd cylinder not getting hot and leaking fuel from it
Assuming the carbs were rebuilt properly, this sounds to me like a carb float being stuck open. Turn off the gas and drain the offending carb. Next, turn the gas back on and sharply tap the float bowl with the plastic handle of a screwdriver as the fuel bowl refills. The goal here is to vibrate the float to free it up. If doing this process a couple of times does not free the float I would remove the carb and look at the float chamber fo any problems such as stuck float, float level not set correctly, and the correct installation of the main jet.
..
Use an air hose to dry out the cylinder then install a new spark plug AFTER you make sure that the cylinder is getting spark. Be sure to balance and sync the carbs when finished.

Consuming problem
There is a tool that adequatly adjusts the carberator. You should ask your dealer about it. It's not very cheap but.... it does works.
How many quarts of oil do i need for a Suzuki 1978 gs 750
Usually they take 3 1/3 qts. Just add 3 and watch till it full with the last bit of oil. Then start the bike and let idle for 5 seconds to fill the oil filter. Let it sit for a couple minutes and recheck the oil level and add more if needed.
