bean can ignition advance module rebuild

[datchew]

Before I begin, has anyone used the motobins advance springs in this rebuild?
I've received info that these WILL NOT work and would like to hear more before I use them.

Why don't they work?

There's an echo on here.


Just messing with you Rob. I'm trying to find out that same question.
Oak told me they don't match the bosch original springs and that they screw up the advance curve of the unit.

If Jason sends his down, I guess i could rebuild 2 cans... 1 with motobins and 1 with originals and then have a comparison... but then, to be meticulous, I'd feel the need to find a dyno and that's just too much like real work.

So, I wanted to get other info/validation/invalidation before I jumped into this.

you want another one to rebuild once mine is welded?

Lemme see how the first one goes and then check with me again.

[datchew]

Right... so off we go.

Begin with a bit of light reading.

And you get your stuff together and end up with this mess after about 20 mins







More tomorrow. Bedtime.

So much mess in so little time. That's got to be some kind of record

Not for me. I can make a mess with the best of them.
Normally, I have cleaner rags, but I wanted to show some team spirit for Stagehand.

Business? I thought you guys were just donating.


he he he. The easy part is done. Disassembly. Now for the cleaning and soldering (did I ever mention how much I hate soldering?)

I'll let you know how it goes. A side business could assist with parts for the /2. Hmmmmm...

[Stagehand]

yeah- Rick Motorad's guy isnt doing rebuilds anymore- this could be a great sideline for you. Salvation comes in a Bean can?

I just got back from a 2500k trip and my g/s is not returning to idle (as quickly) as it should... suspect stretched advance springs due to sustained high speed running (and old/original springs).
I had a similar problem when i first got the ol gal on the road which i sourced to corroded advance weight pins (another case of little/improper maintenance by PO). While i was in there i noticed the springs were decidedly dodgy but replacements weren't available then.
Our BM parts guys (Munich Motorcycles) now offer them - i suspect they're the same as offered by m'bins etc.
I just ordered them so hopefully they'll arrive soon (tomorrow) so i can install and get back to normal...
meanwhile i might get a new trigger sender and perhaps i'll do that install too. But that's a little more involved... ie drilling/replacing rivets i think.
For more info re this stuff check out these sites:

http://www.geocities.com/fwarner_au/...gn_sensor.html
The second one has a method of adding an additional sensor - it's a bit too involved for my simple self. I figure if mine has lasted almost 30 years then one is probably enough. But a new one might just guarantee another couple of decades anyhow.
There's another really good replacement description (with v good pics) is out there by Robin Frankham. I can't find it and have emailed Rob to see if it's still available. I'll post it here if/when i get it.

Yes, neck deep in that right now. It SUCKS!!! Dammit I'm frustrated.


With me, it's the hall sensor. bike just cuts out sporadically. Springs look good though.

Got the sender - good price: $AU20.

Debating whether to replace it or just the springs - s'pose i should seein as i have it now... but how much drama is involved???

Waiting for your story datch b4 i get m'self all worked up too!
