1982 kawasaki CSR 1000 starting problems

I bought a 82 kawasaki csr 1000 recently and have trouble starting it. After crancking for awhile it will fire up and run and once its warm i can shut it off and fire it up again with no problems. But after letting it sit over night it wont start again. Im really hopi by i can figure this out as i would like to rely on it to get me around any help would be appreciated. Thanx

try cleaning carbs out, oiling auto advance unit,also whats the air filter like ,did you start it on prime first then switch to on thats if its been sitting a long time ,i have same model i always put on prime first if stood for a few days .

Like kwaker2000 says,,give it a good service first before panicking . Its a 30+ year old bike,of course its going to cough,wheeze,fart and complain when you wake it up in the mornings.We all do !

How old is the battery? If the battery is not fully charged starting the bike will be a problem; especially when the engine oil is cold. Ed
