    Hey guys, I know this has likely been addressed, but I can't seem to find it. I want to get rid of the old defective bean can on my 91 r100gs, but can't decide between the Motorradd Elektrik replacement "bean can" and the Omega ignition system. My bike is duall plugged running Dyna coils, and this makes the Omega option a bit more spendy. Did the price just go way up on the Omega?:eek1

    Any wisdom is much appreciated.

    I want to hear some FHE on the Motorrad Electrik alternative as well.

    Someone posted on another thread recently about runningone for 3 months now. I need to see if I can track it down.

    We don't have a ton of info on the Alpha yet. Here's what I ran across

    We do have a ton of info on Rick though. He's a great guy and I wouldn't hesitate to buy one of his products. There are a few bikes at the old BMW shop down the road from me, one dual plugged, and the owners are very happy with the Alpha can.

    Another consideration is how this will work with your alternator. The Omega ignition system won't work with an Enduralast alternator. If you're not interested in the Enduralast then it's not a problem. Enduralast is also now making a crank mounted ignition system that fits their alternator for $330.

    I'm running an Enduralast alternator and I put in a points bean can ignition. If the points end up being a hassle then I'll put in the Enduralast system and keep the points can in place as an Armageddon back-up.

    Thanks for the links Brad. I just got back from some errands to start a search around, and behold.... they are there. :clap

    I'm supposed to be studying for a Finance exam. It gave me an excuse to avoid that for a few minutes :D

    That's just something you memorize and forget right after the exam. Don't let you head be full of non-airhead related stuff please.

    Much thanks for the information guys. I have been debating buying electronic ignition for the R90/6 I just picked up. Surprised that the more i look into this, the more likely i am to keep the stock system and just learn to be an expert on it.

    I ran a Boyer solid state for at least 12 years without a glitch and it's still on my shelf awaiting reassignment. I also have an Omega to try out.

    The Omega is simple, low parts count, easy to install and dual plugging is a snap. I had it on my R-90 for a while and I really liked it. Now I'm going to use it to replace the bean can points system in the new/old R-100 engine. With the Omega, you can get the timing right-on-the-money and then dial in the advance curve!

    As far as I'm concerned, you're either a points guy or you're not. I'm not.:lol3

    Ditto. I've seen the Alpha can up close and it's more of a logical evolution of the stock bean can, not anything revolutionary. Much the same way that Rick's Omega charging system is what the stock alternator should be. With the /5, I've still got points (but did add a Dyna Points Booster last year), but if I did get a bike that needed an beancan replacement, I'd go for it.

    I do have the Omega alternator on the /5, so I'm not too incurable a Luddite...

    I've got Rick's Alpha built for dual plugging on one of the G/Ss and it runs perfect from 0 to redline..and for cruising at 65 all day long.

    Actually...I had the first Alpha for stock airheads about 5 months ago...but it was stolen out of my car before I could install it. If anyone happens to see one anywhere in the Bay area flea market or swap meets, please let me know....then duck while I find that #$%#%

    Does anyone here have experience with the Hot-Spark high energy coils? Would they give my beemer a boost? Maybe an intermediate position between electronic ignition and points?

    Thanks,

    The problem with "high energy coils" is that they draw more current than a stock coil, which can cause excessive point burning. A hotter spark doesn't necessarily mean a hotter engine-- once you get past the optimum spark energy to ignite the fuel-air mixture hotter doesn't add anything.

    I fitted the latest Boyer Micro power system to my 1000 cc twin plugged G/S.

    The PO had just retarded the stock ignition a few degrees and used Jap twin coils coils 2.5 ohm resistance, 1 ohm more than stock.

    As you might expect it wasnt working that well.
    .

    The Boyer system includes two twin mini coils and four plug leads , and landed the lot cost a bit less than the Omega ignition system only.

    I had a points bean can which I picked up for GBP6- on ebay and it fitted inside easily, the magnet plate slipping down over the bob weight pins and the pick up plate replacing the points plate. It is listed as for a points can only but I cant see why it wouldnt fit a hall sensor can.

    My rev counter doesnt work , and my timing light is a bit erratic, so it was set by trial and error up my usual test hill.

    I ended up with around 26 degrees advance coming in around 3500 revs, and this gets me up the hill around 25 km faster than the old system , and easier starting , smoother running and a couple of extra km/ liter as a bonus.

    O.K. looks like we're pretty much on the same page, Alpha can is closer to stock, Omega lets you keep a back-up system on the bike and ready for any possible break-down, with the added advantage of not running off of the worn-out timing chain...but the Enduralst alternator is tempting... I guess what I would really like to do is put the thing back to points, but I think the points bean-cans are getting pretty scarce. Anyone running a dual plug bike on points? It seems like it would be fine, mabey a little less life span...I'm definitly a breaker points guy if I don't have to spend a fortune to get it to work.

    Here's another bit of insanity I've been pondering, I have a dead slash 5 motor and have given some thought to swapping out the whole front end on my r-100 for the old style one with the points and all...any body know if this is do-able? Is it imoral?

    Thanks for all the help!

    I put an Alpha from Rick on my 83 R100 after the stock beaner failed, has been flawless and even better than I expected. Have had it for 3 months going on 4 now and I ride everyday commuting 100 miles each day on it here in Texas, where its cold in the morning and hot in the afternoon. Well worth the investment for reliability, function and ease of replacing the hall unit if ever needed. Thats my 3ยข worth...

    The front of the camshaft is different. Nothing for the point mechnism to ride on with the later cam.
    ...and even if you could, yes, it would be immoral.

    If youre going to go with a /5 points and covers on an R-100 engine, youre going to have to think this swap through carefully and a set of /6 parts might work better, since the /6 cover is vented.

    You'll not only need to swap the covers but you'll need a cam that has the points nose and the lifters. If those parts are worn, you might do well to source new parts. The /5 and /6 engines have a mechanical tach drive you can pull the tach drive out and have a plug machined to fill the hole (That was my solution anyway.) and then run either simplex or a duplex timing chain, depending on what gears you run.

    I may have forgotten something but basically, thats the swap.

    This seem like a real complicated way to go nowhere, considering the ease of installing an electronic ignition but I guess points guys, are points guys....

    I did not know that, thanks, and the imoral part bothers me too...
    I'm thinking the Alpha can may be the way, I allready carry a spare igition amp on long trips.
