Okay, so this is not hawk related.

My buddy bought an 82 KZ750 as a bike to learn how to ride on. So far he has been doing okay. When he bought the bike the seller mentioned he had recently put in a new battery, but keeps the bike on a battery tender to make sure it maintains a charge since it was not his primary ride.

Now...my buddy is still having problems starting the bike from a dead stop, the the couple times we have been out riding he would stall the bike a bunch of times and have to resort to kick starting the thing. He was keeping the bike at my place and I left a battery tender on it also while it was here.

A couple weeks ago we took the bike over to his house and he has only tried to ride is once since. Apparently it was not on a battery tender and he had a rough time getting it to start.

I went over yesterday to see if I could help him out since he is not good at kicking the bike over yet. I was able to get it started but it was running like ****. It kept back firing at low rpms and then would eventually stall. On restart I could not keep it running as well. So we jumped it on another battery and it ran fine until we took off the starter cables.

I was originally thinking that this was a stator or alternator problem as the battery was not charging correctly. I really know nothing about electronics though so any help would be grately appreciated.
