Not in it's best form, however. :P

[smiley=puke2.gif] Bummer, but not as spectacular as Joan's. :o I do love the way the rings kept the piston from falling apart! ;)

That reminds me. I still have to send away for Oaks top end guide.

Top End Guide?

Oh. Poor little red R65. :( The girl didn't look too happy either. I'm assuming it belongs to her anyway.
You are right, Justin. Joan's was much more spectacular. She had better pictures too. ;)

A R65 on YouTube. Looks kinda familiar... :(

Yikes!!!! At least I haven't had that happen to me (not yet, anyway)! ::)

Wow, that one's gone around a few times.
Yes, the Blueberry is still lashed to the wooden repair stand.... hey! My digicam takes 30 second vids, maybe I should make a movie of her just sitting there? Yeah right. ;)
The last problem is somewhere from the battery to the starter. When I saw Ken last (yes, I took the relay with me to Texas!) he tested the starter relay with a DVM and a 12v moto battery and called it a good relay. I guess that means the problem is between the relay and the starter itself. Hit the starter button and the relay clicks, but no response from the starter, AND I can run a jumper direct from the 12+ to the starter + and she springs to life! ARGH!
-
Joan, I had the same problem with my original starter relay, it would click but nothing else would happen, and it was the relay itself. I confirmed this by pushing down on the top of the relay case, (mine was plastic) and I could get the starter to work. I removed the relay cover and adjusted the spring loaded contact arm of the relay down a bit, so it would work again, and got another 15 years out of it before it died for good.
-
Oh! Bob! I'm gonna go try that right NOW!!
(back from garage)
No joy. It sure clicks nicely, though!
-
Another test you could do,is to remove the relay from it's socket, and jumper the pins on the connector. I don't know your mechanical abilities, or if your're comfortable doing this, but if you locate the pins in the socket that correspond to the pin numbers :30 and 87 on the relay you can put a jumper wire across both of them , and if the relay was the problem, the starter should rotate. You may get a little sparking, but you're only going to do this for a second or two. Just make sure the transmission is in neutral, so you don't get any unwelcomed surprise!
-
Hee hee... Thanks Bob! I'm going to try it. (Home with a nasty bug today, lucky me!)
Iirc, 30 is 12V+ to the relay, and 87 must be + to the starter. A nice long piece of 14g with tinned ends, but what's the best way to get the jumper ends "across" 30 and 87 while the relay is plugged in? Hmmm. I'm going in!
(she returns)
I figured it out. But dang, it still isn't giving it. AND I suddenly remembered the '86 R65 in the other corner of the garage, brought home in January. Took off the tank and YES, it is the same relay as Blueberry! Tried it: click-thunk. No joy. Hmmm.
-
I would recommend removing the relay, but it probably will be a bit difficult, a flat blade screw driver and pry up on each side until it's out. Then jumper the pins on connector that the relay was plugged into.

Oh! Thanks, Bob! That's something I didn't try. However, if using a known good relay still gets only a click, I'm thinking the electricity is not flowing right from the relay socket to the starter solenoid.
Or maybe a bit more extra dark roast will help clear the fuzz out of my head! ;D
Bob, I really appreciate your helpful hints!
-
I guess if you replaced the relay with a known good one, the relay isn't the problem. Next is to get to the starter and check the solenoid and see if power is getting there. If you need starter parts, Euro Motoelectrics in Monument , Colorado has just about everything you need to rebuild a starter, now whether it's cost effective, I guess that's up to you.
-
My money is on the starter solenoid, though I suppose it could also be that you have a bad winding in the starter
itself. Depending on the orientation of the rotor when it last stopped, it might be in a good spot to start it spinning, or
it might be in the dead zone, in which it won't move at all unless it gets bumped. But, usually the simpler thing is
to check the solenoid first. Now, I have done this on automobiles, but not on airheads (yet).

The starter spins up well and starts the bike perfectly when I apply 12V direct to the starter solenoid with the jumper, which I'm thinking means the starter is okay. When I had the bike all buttoned up and ready to pressuring the oiling system prior to starting, the jumper wire is how I managed to turn the motor over enough to do that.
I've heard good things about the guy in Monument CO, but I surely wish Rick Jones had an airhead cheater booklet for starters like he does for the charging system! :)
So the relay is good, starter is good... I'm missing something important. I know the neutral switch connections are freshened and tight, and so is the ground wire at the gearbox bolt. All the wires under the front cover are where they are supposed to be connected. Humpf. I think she's punishing me for leaving her in drydock so long! ;)

The button on the handlebar?

I've got a wiring diagram from my BMW shop manual, so I don't know how accurate it is for all R65's, or wire colors, but here goes ! On your starter relay connector, there should be a red wire ( a fairly large wire 2.5 sq. mm) and it goes to pin 30 on the relay. This is 12 v from the positive terminal of the battery, this is 'hot ' all the time, that is, power is available all the time. Check this with a voltmeter to see if you have power from the battery. If you don't you need to find the problem with this wire. If you do have power, you need to check for continuity ( low resistance a few ohms or less) in the wire from pin 87 of the starter relay connector to the starter solenoid, it should be a black wire 2.5 sq. mm . My wiring diagram shows that this wire goes through a two pin connector that also has a small blue wire as well. There doesn't seem to be anything else in the circuit that could cause a problem.
-
Yeah, I've got that nice shop manual, too! About the time I was headed back down to the garage yesterday to do more fiddling, an electrical storm came through pretty close by (she laughs), so ran around turning off the major appliances like the computers and gadgets, then I went to bed. I was home sick yesterday, after all. :(
I'll get back to it tonight, I hope. The Blueberry had better be ready to ride when I am! ;D
Thanks again for your help, Bob!

Starter relay... Doh! I tried everything to suss out a starter problem. Everything was right and it worked if I shorted the solenoid or relay. it turned out to be the connector block under the tank on the right running from the handlebar button. They can get a little furry inside causing an intermittent cut out on the button to relay circuit.

Thanks for the feedback!
