14.2 to 14.5V is what you normally see when revved. 13.9's a little low but acceptable. I'd let it be.
Are we ever really done with our 650? lol. I don't recall seeing you do any handling upgrades here. Steering head bearings usually need replacing, better rear shocks really help, Minton Mods in the forks, TX750 swingarm swap, that all should keep you busy for a bit, lol.
*disclaimer, I almost never know what I’m talking about* but to the effect of your starter issues, mine is the same way and I’ve been reading until the time comes to broach the issue. Is the starter motor slow to turn over? Tried bypassing the relay with a jump from battery? If all connections check out, maybe oil -filled starter motor or bad brushes? I haven’t pulled mine yet, but all elec. issues check out so I’m gonna expecting a VERY well lubricated motor.. anyway, beautiful bike!Getting my bike started cold using the starter has been an issue and usually drains the battery enough to have to resort to old kick-start. So I checked the voltage with headlight unplugged across battery. @ idle 12.6 and @2500 rpm I get 13.9. I changed the rectifier and same results. So history of electrical already is replaced stator, brushes, battery load tested good, wires all tested, ignition switched cleaned and tested. I did fix my bike breaking down from past issues, but now would like the battery to at least be able to start using starter when bike cold. I have looked at curly's guide so will try and follow some of the steps when I get chance. Is the 13.9 volt reading low enough to be concerned about the low charge? Or am I just about to dig a hole for no reason?
Nice. I won’t be far behind. Maybe your bike has similar symptoms, even fresh off of the charger, starter motor is very sluggish, but after warming up (and assumingly softening up all of the sludge inside) it turns right overYeah I am suspecting the starter motor brushes or the oil filled scenerio. I have checked everything else and I am going to wait till an oil change is needed before I pull the starter motor.
I am still away from the shed until May is why there hasn't been any new updates on the build. My wife is wondering what all the packages I have received in the mail are since I've been gone . I told her not to look in them, because they are her Bday presents and I don't want to spoil the surprise.
... a lean condition out idle once hot. I went up a size on pilot jet and two on main jet. I found the mix at idle but once the bike got hot it was lean...
