V-strom build

[TheIglu]

You are doing all this for under a grand?

Well then, carry on.

I *think* you've answered this elsewhere Randy, but who are you using for a machine shop?

custom fab stuff has been done at B&B Fabricating here in Farmington and dealer installation at Rochester Motorsports

I dropped my stator side cover off at KJE Automotive in Rochester a few days ago to drill the stator bolt holes and tap them all the way thru

[RandyO]

Significant progress, the external auxiliary alternator is mechanically installed, still have to fabricate an auxiliary battery box and do the wiring

[RandyO]

Alternator is a Powermaster 8182 75 amp rated for up to 20,000 rpm, between the stock alternator and the auxiliary alternator, I will have 108 amps on tap

Powermaster Performance

What ratio are you driving this at (since it doesn't come with a pulley...)? I see most ratings at 6K RPM as the industry standard. I notice the part #8182 has 7A at "idle" and 75 A at max rpm, vs. the 8162 at 30 A idle and 55A max respectively. If they're rating it at 13.5V, you're looking at 1458 watts at peak speed? This seems odd since you're into insulation, not heated gear.

I use insulation for the coldest weather where I only ride solo (25°f and colder), electricity for above and maybe 2up


pulley ratio is 1.5:1, the guy I bought it from did a lot of experimentation with pulley ratio and load testing at various rpm, initially he was using a different alternator but it couldn't handle the high rpm of a bike, hence the reason for the 8182, his testing showed that it puts out over 50 amps at V-strom 1k cruising rpms.he ran this setup for nearly 2 years until he returned his Vee to stock and sold the bike. then offered me the setup for $200

Looks like my auxiliary battery will be a DS42B24R (Prius) , I will have to notch my inner fender for clearance

leaning toward a yellow top optima, designed for both starting and deep cycle, 450CCA, with the extra power, I will easily have enuf for 2up heat,100watt eurobeam driving lamp, 55watt fog lamp (both Hella 4000s) a set of low mounted leds, heated seat (rider and pillion) and a 200 watt inverter, as well as gps,radar & autocom

[Tekime]

Awesome project. Looks super clean too. So in the summer you can power a railgun which will be nice.

Randy... missed you at the peeps all the usual suspects were there

Take a look at a marine battery if they are small enough, they take lots of physical and electrical abuse

marine batteries are not rated for cold starts, I considered them, not many people go boating when it's -30°

just ordered the battery, found it for $123.74, over $100 off list price of $225.99

[RandyO]

now I get to work on the box, I will make a cardboard mock-up to give to my local fab shop, end result will be tight fitting box about 5" higher than in the photo

[RandyO]

ready to make progress again, but am rethinking my battery location

it would be much easier to mount the battery and all the components in a NEMA 4 box on my luggage rack, it would be more easily accessible, and the Optima battery is an AGM so it don't need to be mounted vertical, the downside is higher center of gravity, the 23 lb battery will be nearly a foot higher, and behind the rear axle

a custom battery box would be much more complicated, and cut into the underside of the tail with barely any clearance between the chain guard at full compression of the suspension

[Stromper]

Brave enough for lithium

search ebay for the box also Nema 12 would be fine too

lithium was not even a consideration, cold weather reliability was my #1 consideration when choosing a battery, and Li is not there yet

NEMA 12 is primarily an indoor enclosure, not rated for water tightness that the NEMA 4 is

[RandyO]

been looking at this enclosure

4 years later......... the build was put on hold while I was getting my seizure disorder under control. haven't even registered the bike in 2 years. Today, it went off to my dealer for service & inspection, I will get it registered tomorrow, so they can put a sticker on it.

Then I'm back to the build, first thing is the battery box, then an auxiliary wire harness, and hook it all up.

after that, next on list is a Russell Day Long Saddle

and somewhere in future is an expanded fuel tank

Attaboy!

[RandyO]

I learned today, I may have a rusty fuel tank issue

[RandyO]

[Stoneman]

Let me know if/when you want a hand with that so we can make sure the entire tank gets coated proper!

[Stromper]

Randy Strommer are have an intimate Peep show up at Cupsuptic/Rangely

Poorly attended all the Canucks are some where else in Northern Quebec
