Re: New to me bike 1981 Suzuki 650 gs need general...
Hi and welcome to FixYa,
A couple of ideas you may want to consider when starting a bike that has not run for some time:
drain the carbs - there are drain screws at the very bottom of each carb for this purpose. Of course best would be to rebuilt the carbs or at least, disassemble and clean;
of course change to a fully charge battery;
remove the sparkplugs, get a clean dry sprayer similar to those used with plants;
fill the sprayer with some 2T oil, used for 2 stroke engines;
spray the inside of each cylinder through the empty sparkplug hole at least one spray. if the sparkplug holes are rather deep, you can use a short length of a hose;
test crank the engine with no plugs. this is to exercise the parts inside and evenly spread the sprayed 2T oil around the piston and rings;
ensure drain screws are closed, fill your tank open fuel valve. On most Suzuki, there are 3 positions, ON, RES and PRI. On the initial start pls use the PRI. The fuel will flow. The other two would require vacuum to open the valve.
confirm that fuel has entered the bowls of the carbs by opening the drain screw just to check;
in some instances, there would be an overflow on the very first filling of the carbs.
Other than the above a few more but these would initially be of help for the moment.
Would appreciate an update, curious myself.
Good luck and Thank you for using FixYa. Happy New Year.

Check compression of cylinders, all should be close the same. Swap spark plugs and check if problem cylinder moved. If bike sits for long periods of time then most likely it will be a plugged carburetor.
hi,i have one of these,great old bike,parts are becoming an issue,but never fear,try"bikebandit.com",they are based in the uk,but ship worldwide,and are very reasonably priced,i am based in new zealand and all parts i order are normally here inside 10 days..hope this helps..cheers
Sounds like the battery you have in the bike has gone bad sence you have to jump start it all the time. And yes the bike will run bad cause the cdi need a good voltage to work correctly. Get new one and put in new asid in and put it on the charger till it is fully charged and you should be good to go.
Theres a site glass on the engine, tells ya how much to put in. tranny an oil are the same should be about 2.5 or 3 qts total. filter on front o block, change too. don't pinch o ring. Can't change oil get off bike!!!!!!
Great bike !.i recommend Castrol Syntec Actevo motorcycle oil 10-40wt buy 4 qts...After draining oil and replacing filter and drain bolt pour 1 qt in dipstick hole w/bike level on level ground..check dipstick and top up slowly while checking dipstick
continuously so as not to over fill.....Good Luck to you friend......Tim
