    Upgrading Everything Need Suggestions on Starter and alternator

    I am stripping down my 77 r100/7, electrical and everything and I am replacing the alternator and starter. I want to go with top of the line. Iíve heard that Cognito Moto sells a solid Enduralast unit but I also heard Silent Hektik is great as well. As for starters Iím unsure which one to go with. Definitely not Bosch. Any suggestions? FYI Iím running everything to a Moto gadget m unit blue.

    I have a 1977 R100RS (a /7). Some vendors that I like doing business with are Motorrad Elektrik and EME (Euro MotoElectrics)

    Rick at Motorrad Elektrik has a Nipon Denso-based starter that uses planetary gears (without glued in magnets) that I like (and use).

    Both EME and Motorrad Elektrik have options for charging systems (I have one of each for my airheads). I have only heard good things
    about both. The EME system uses permanent magnets rather than the energized magnets, but both systems give a greater output than
    the stock system, are reliable, and well supported.

    I use a Boyer electronic ignition which has been trouble free for over 20 years.

    Rick Jones at Motorrad Elektrik has a "must have" book on airhead charging systems -

    I went that route.
    I replaced the alternator with Motoradd Electrik alternator upgrade and have had nothing but success with that upgrade. Mine, a few years ago was the 400 Watt alternator and I have no issue running a pair of halogen H3 running lights (one 35w & the other 55w) and a heated jacket liner at the same time. The installation was straight forward and it has lasted years. I hear the other alternator upgrade is similarly well regarded (euromotoelectrics)
    For the starter, on my 82 RS it came with a Bosch starter. I simply had it rebuilt by a local guy and it has been flawless. I have heard about using Toyota starters, but I don't see the point of throwing stuff out if it just needs freshening

    Newer design starters seem to spin the engine faster than the old Boschís, but the older starters were known to be more reliable. I replaced a troublesome glued magnet Valeo with a Caltric brand purchased on eBay. Although it cost only $60 new, the Caltric has performed flawlessly for several years.

    I have one of these that is approaching 30 years old and it still works perfectly.

    Also, since you're in there doing stuff, I highly recommend the Wedgetail ignition system. I could not believe how much better my R80 G/SPD+ started and idled after I installed this system.

    (That is Motorrad Elektrik's Omega Charging System in there, as well. I replaced the near 30-year old Omega that was in there just because I wanted a new one).
