stator and rectifier resistance a smidge low

Hi, my 86 750 is reading .2 on a stator test. Normal is .34 -.4???? Is this low enough to warrant replacing it? Hate to spend the money if it's not needed. Same deal on the resistance test on the rectifier just a smidge low. Thanks

what is your charging output voltage? Also check all connectors for corrosion very carefully...i found that to be the problem with mine.

Output voltage rarely hits 13 - 13.5 volts

The resistance part is fine but like Slim stated make sure your run all the other tests before you come to your conclusion.

If I charge the battery full I can start and ride all day. I did notice that one a lenghthy ride when I shut it off the starter will barely turn over. It happened today then we went out for a while when I got home it started right up once it cooled down. Seems to me like maybe a breakdown somewhere when it gets hot. R/R perhaps?

Do you have a Maintenance Free battery?? It almost sounds like you have an old battery or a wet cell that is low on electrolyte. Heat can cause the symptoms you give with a worn battery or one low on fluid. Either situation is not good for the charging system.
I wouldn't worry too much about the resistance readings yet. My first concern would be the battery. I'd get it load tested to see if it's up to snuff. Most auto parts stores will do this for you.

If you are still running with the old wet cell battery do yourself a HUGE favor and pick up a M/F right away. Solves 98% of hot start probs. Wally World even carries them so no excuse not to have one. Theres one on every other block anymore...lol.

I just put a brand new wet cell in last week when I got the bike. Kawai dealer recomended wet cell. I had a bad feeling when I replaced an old MF with a wet cell. Old MF would not even take a charge.

Battery

HUH?......Your dealer recommended a wet cell over a MF? I would be looking for a new dealer!

Remember the commercial a few years ago where it stated that if you weren't happy with your new tires on your car----feel free to return them. Then you saw an old lady pitch one through the front window of the tire dealer?

Hmmmmm..............For some reason that commercial seems to come to my feeble mind reguarding that wet cell battery..........
