There was a recent post (may still be going on,
http://www.vtxoa.com/forums/showthread.php?t=212825&highlight=starter+removal) about starter problems, and in the middle was this write up (which I saved for future reference);
OK I finally found my problem and fixed it. Short story: It was a bad STARTER.
Long story: I tried all the suggestions - THANKS GUYS! I traced my problem to a suspected starter problem, and I ordered one from Hal. Honda had it on backorder for fricken forever so I just recently received it.
Removal/Installation? Well let's just say you won't do it by the book. No way it'll come out by following Honda's Service Manual with the engine in the frame - no way. You can easily get it lose, but it won't go anywhere. (You MAY be able to snake it out if you remove the upper motor mount bracket, but I didn't try it because I couldn't get to the starter wire.) The trick is to remove the bottom radiator hose and the bottom two bolts holding the radiator to the frame. Leave the top radiator hose and top radiator bolt connected (heck I needed to change the fluid anyways). Loosen nothing else (no wiring, no fan motor, no radiator frame pieces, nothing.). This will give you plenty of room to remove the starter wire and get the starter out the front of the frame (without scratching the frame cross member).
EDIT FROM A LATER POST:
Also, I found an easier way to get to your starter (the wire or to remove the starter entirely). Don't follow the manual - it won't work (not enough room). Previously I wrote to remove the bottom mounting bolts and disconnect the bottom radiator hose, leaving the radiator to hang from the single top bolt. Well, its even easier to just unbolt the bottom and top bolts (without disconnecting any hoses) and let the radiator hang from the hoses. This creates enough room to remove the starter wires and starter without the coolant mess.
END EDIT
Note the Honda Manual tells you to remove the "starter drive gear". Well, that means taking off the left hand crankcase cover (and I don't mean just the decorative chrome cover in the center - I mean opening the case.) Well, there is no need to do that (unless you want to check - the torque limiter, starter drive gear, and/or bearings - I didn't.) The starter will come lose (and reinstall) just fine with the torque limiter gear in place. I stabbed it back in the first try - no problem.
OK with the old starter out, I took it apart to check it out. The commutator bars were excessively black, in my opinion - all of them uniformly. Not wiped with rings of discoloration or scratches, but pitch black everywhere the brushes contacted them. I cleaned them up with Tarn-X (and a lot of scrubbing) to look like new.
Everything else checked out fine (everything), except there was NO continuity between the commutator bars and the armature shaft - nothing on any of them. I've concluded I have an open short per page 18-7 of Honda's Service Manual. This appears to be a ground back to the engine/frame/battery. Apparently, there is some flow elsewhere when the starter is engaged, but not enough to turn the engine over.
Anyway, the new starter (the one last thing I changed) SCREAMS that engine to life. No lugging, no slow starts, no intermittent problems, nothing - it screams alive so fast I can hardly tell the starter engages. Quite a contrast from before. It even started that fast after the bike sat on PepsX's bike stand for months (and it never fell over ) - i.e. with lower battery voltage.
So there you have it. My problem solved. If you are experiencing similar problems - check all your wiring and starter relay first. The starter costs $90.00.
