    I would like to hear more about this mod. did your battery run the piaas, until dead, then turn em off for recharge???? Did the battery give you enough juice to run all day with the lights on, 55 each piaaa, 55 headlight , heated gear 80, gps , radio, phone charger lets say 10, thats 250 watts on a 300 watt system not including a low or weak battery and system costs, am i wrong here?
    I know the alt is constant output and excess is discharged but what if you hit the max because of the old system? is it a burn out, then a replacement

    Any specific concerns ?

    The crank snout loading is not a problem.



    Your call on the choice of tug. For mainly asphalt and forestry/Alcan Hwy style work I'd run the 'wing. My 'glide has more ground clearance under the bike than the bm' had.

    The auto alternator would be the best idea.I had a optima auto battery in the trunk, I only ran the Piaa's at night when needed, wiring the headlight through a relay and using the existing headlight wiring to turn the relays on and off makes for a very bright headlight.I usually maintain my motorcycles on battery maintainers year around. If I where going to travel long distances a 30 year old bike wouldn't be my first, but those old wings where a pretty bullet proof setup and parts are everywhere for them. Since I have an 1150gsa based rig now they are way different beasts.DB

    The concerns I have, rain and the back of the alternator and belt slippage, keeping the tension on the belt, cracking of the long arm mounts, bolting the pulley to the crank, keyed or not, rain entering the timing belt covers. Are you Sorry you asked?

    Sorry ? ... hell no :lol3


    Rain , ask Whitlam ( bmeuro's old rig , R100gspd ) , not a problem. Belt housing can be sealed , depends on your choice of crank pulley offset.

    Slippage , zero , zip , zilch if you use the correct belt for the pulleys that you choose.

    Cracked mounts , proper preparation prevents piss poor performance ... build it right the first time :D

    Tension , non issue ... next ?

    Adaptation of drive pulley to crank , non issue if you stop and look at it. If in doubt consult local engineering shop. Simple job. Cat' , cummins , detroit plus numerous car manufacturers over the years employed the same stacking of crank pulleys bolted to the harmonic balancer ... bottom line , non issue.

    If the GL/eml works good it maybe easier(cheaper) to improve than mounting chair on GS the poorboy set up seems like a great idea to me if your afraid of water in the belt covers drill some drains,and mount a car battery someplace. Get the Headlight relay setup http://easternbeaver.com/Main/Wiring_Kits/wiring_kits.html
    Onward ans forward.DB
