Electronic ignition... how to match oem to aftermarket...?

Im thinking about trying. I have never worked on a bike before, so I was hoping for an easy bolt on product.

I just checked an online parts fische for your 85 GS300L. The stock ignitor and crank trigger are no longer available so I dont see that you have much choice in adapting a Dyna to fit your bike. How much mechanical experience do you have? Work on cars, lawnmowers, outboards or anything, any wrenching experience? Where are you? Maybe there is someone close enough by to lend a hand. Adapting a dyna is not that difficult, but a lot depends on mechanical experience as to how difficult it may seem.

If it means just slipping a mechanical advance on I can do that. Would the mechanical advance work for my bike just by putting it on? Is there any adjustments that I may have to make to the unit in order for it to correctly adjust my ignition? I can put things together etc. but I have little experience trying to time ignition. I'm not afraid to work on the bike, I am just concerned at spending hundreds on something and not get the right parts.

Thank you,

The stock ignition rotor shaft that is fitted on the right end of the crankshaft is keyed into a recess on the crank end. The mechanical advance is a plate with a rotor shaft and two spring controlled advance counterweights. As the crankshaft turns, centrifugal force opens the weight arms which rotate the rotor shaft, which advances the point the rotor and triggers activate. There is no setting or adjustment of the installation of the advance mechanism. It keys into the same recess as the original rotor shaft did. Its literally, a stick it in part. Takes two seconds. :-) The part that complicates matters is that stock ignitions were manufactured by two companies in two configurations and the rotor shaft may be short or long. If its long, a dyna rotor once installed on the shaft may be too tall for the stock ignition cover to be put back on. Also, the two types use a different rotor, and they are not interchangeable. The mechanical advance unit make you use will determine the dyna style you need, either ND (Nippondenso) or KD (kokusan) Ask which it is when you buy one Mechanical advance units for ND systems used points held to the breaker plate with one screw. Advance units for KD systems used points held to the breaker plate with two screws. You may need to make a spacer to fit between the ignition cover and the crankcase to get enough clearance for the rotor so you can install the cover. I dont have a 300L, so I dont know the exact dimensions of your cover.

As far as I know, all GS models used the same diameter ignition base/breaker plate, so you should be ok there. Also, some GS models without adjustable electronic ignitions were not made with a plate and timing marks because there was no way to change the timing. Depending, you may need to find #1 TDC and draw a degree wheel to determine where to time the ignition once installed. Do you have a Clymer or service book for the bike that gives any info about timing it>

Also, from Sleepy's thread on ignitions...................
"Has anyone bought from Z1 Enterprises? Their prices on the ignitions are the lowest I found? $145.00"
Just in case you're looking for a source for a Dyna at a good price.

Thank you Earl for your help. I will have to look at my bike more once I get back from vacation in a week or so. I don't have a service manual yet, getting there though. Hopefully I will be able to ride again this year....

Later,

Earl or someone else, how do I determine which model of Dyna S to get? Some of them looked like the coils had different angles on the ignition plate. Though I think my GS300L had 180 degree coils on the plate. Not certain though.
 
For what it's worth, I just finished installing a Dyna S, coils and wires on my GS1000. It was a good afternoons project. I noticed an immediate difference in starting and idling. I'm going to find a timing light and time it before I go on a long ride.

And I have a spare mechanical advancer for my bike. PM me if you're interested.
 
Do you still have that advance available? Do you have any specs on it?

Thank you
intercessor
 
Update on Dyna ignition system install:

One of the smarter moves I've made. Big difference in performance.

Still got the extra mechanical advance unit. Anybody here know about interchangeability? I have a GS 1000.

intercessor, where are you located?
 
THE ignition type gs's is induction ignition.and thats from accel . or other wise known as Mr. gasket
 
Newbie needs a little help

Newbie needs a little help

I'm currently breathing new life into a 1978 GS-1000 and need a little guidance. I used to make my living working on these things but that was 20+ years ago and, well, you know................I've slept since then! The gentleman that sold me the scoot told me it had a bad ignition coil (it does not). It appears that he trusted a shadetree mechanic to "help him out" at one time or another. His buddy basically destroyed the points plate and all the screws too. Having worked on mostly old Hondas for years this came as no surprise. I decided to replace the whole ignition assembly right? Wrong! I almost needed CPR when I saw how much $$ they wanted for that. I've been reading about this Dyna S system on this forum. (BTW, this is an AWESOME resource. Thanks!) Where is the best place to buy the Dyna and what should I expect to pay? I dont mind paying $100+ for a "set it and forget it" setup. I've tried finding it on the web but have only found "late" model stuff. Any links you could share with me? Thanks again for such a cool site! Guy
 
Call Dynatek directly and buy a Dyna-S for about $155 to your door.

800-928-3962.

The one I bought recently had a bad trigger (1-4) it was only a few weeks old. Turns out my 1-4 coil was bad also a Dyna 3 ohm. Dyna offered to replace it if found faulty for $35. I bought 2 for $70. While I waited for my new Dyna-S replacement, I wired the old ignitor back in with the new coils. Worked great. They sent me a no charge Dyna -S to replace the faulty 1-4 triggered one.

Great customer service, eventhough the new part didn't last the first time. They made good on their faulty component, so I still have faith in them.
 
Thanks C/T

Thanks C/T

Got one on the way as we speak! Man, I'm getting excited now. Just got confirmation that the tires (GT501s) will be here tomorrow and the ignition in a couple of days! Any Houston / Galveston guys here? I'm gonna be getting bugs in my teeth even sooner than i had hoped! Guy
