gs1100l,starts good cold, not so good hot

[claude ouellet]

I have a 1983 gs 1100L, I bought it last summer ad ran it for about 12000 k. until now I never had any problems with it. Yesterday I went for a ride of about 100k, I stoped and turned the ignition off. Five minutes after I tried to start it again but it seems like the starter did not have enough power to cranck the engine. I waited 15 minutes and it finally went. Back home I retried the same thing and it did it again. I tested the batterie, it looked a bit to low for me at 12v so I changed for a new one. now it stars better with more power but I think the problem is not fix and I am scare to go far with it. Is this like I think a compression problem
If someone can help me, it would be very nice.
Thanks
Claude

Connect volt meter to battery. Start engine & rev it up. Voltage should climb to near 14v. If it don't, you have a charging problem.

Thanks for the quick answer.
I just did what you told me to and it goes just a bit over 13v. But yesterday with the new baterie it did charge at about 13.5, .6v is this normal and what do I do about it.
Thanks again

You may also have a problem with the starter motor, the solenoid, and/or the wiring. Or all three.
