Zero Motorcycles Forum | 2013+ / Re: What DS tires woud fit an FXS ?
« on: February 17, 2019, 01:00:20 PM »
In the attached file, I have listed the available sizes of some tires for the FXS.

Amazing work. Thanks!

I talked to a parts guy at my Zero dealer, who wasn't much help, but had more luck at another store. So I now have Continental TKC-80, 120/70-R17 for the front and 130/80-R17 for the rear. Initially they gave me 140/80-R17 but that would have been too close to the rear fender.

Zero Motorcycles Forum | 2013+ / What DS tires would fit an FXS ?
« on: January 31, 2019, 08:03:22 AM »
I bought an FXS in 2017, on a $2000 year-end discount. They sold the last FX just before I reached the store  :( The FXS is great, but it slides on the gravel roads near my new house in the wet.

What dual-sport tires can I mount on the FSX rims ?
The handbook says the rims are 3.00 x 17" front and 3.50 x 17". Currently it's got Pirelli Diablo Rosso II 110/70-R17 and 140/70-R17

I'm thinking about Pirelli MT-60 130/80-17 for the rear, same as the DS, and 110/90 - 17 for the front.
Or maybe Pirelli Scorpion 130/80 R 17 on the rear and 110/70 R 17 for the front.

Zero Motorcycles Forum | 2013+ / Bike speed "current limited"
« on: December 13, 2017, 01:13:04 PM »
I have a 2017 model FXS  ZF3.6 modular with one battery pack. Supposedly the top speed is 120km/h sustained. This is a fairly new bike (2 months) with fairly low mileage.

On a few occasions the bike has stalled out at a much lower speed - twisting the throttle has little effect.
Yesterday the bike limited to about 71km/h on a slight downhill, and later to about 65km/h on a bridge where many vehicles go 80. Kind of embarrassing.

The motorcycle log as downloaded via the Android app showed messages such as
 2017-12-11T19:23:13 Batt Dischg Cur Limited 133 A (51%), MinCell: 3485mV, MaxPackTemp: 12C

Has anyone else seen this ?
I believe adding a second battery module would probably fix it, but that's somewhat expensive...

I made a map with Zeemaps that allows users to add their electric motorcycle to a worldwide map of other riders:
https://www.zeemaps.com/view?group=939336&x=8.461561&y=20.545427&z=15

Go to the link above, click "add" and enter your information. I hope people put their email so other users can contact them.

Enjoy!

I just tried that link in my Firefox 52 and could not see how to add an entry. The base URL at

Add a left hand rear brake, many have, Zero should.

Just did that; see my reply to  http://electricmotorcycleforum.com/boards/index.php?topic=7066.msg58399

Works nicely on my ramp, at least the one I use for my truck.

Zero Motorcycles Forum | 2013+ / Re: Proposal and RFC left hand rear brake
« on: December 03, 2017, 02:06:50 PM »
I was considering the following:

Get left hand brake cylinder/lever.
Locate line from rear master cylinder to ABS and disconnect from cylinder.
Reroute line to front and connect to left hand master cylinder.
Fill, bleed, good?

Anyone know why this would not work? Any suggestions or recommendations? Anyone already done this?


I did that recently. I got a left-hand brake lever with master cylinder from a local bike shop (not sure what's it's off - he said "does it matter?"). The rear brake line is just about the right length. I was able to bleed out the line through the master cylinder - I took the lid off and pumped carefully, keeping the cylinder filled with fluid and watching bubbles till they stopped and I was able to feel the brake work. My aim was to have an effective left-hand control to use while backing my bike down a narrow ramp - without a clutch and the resistance of a piston engine, the front brake alone cannot hold the bike. That works fine.

What did not work was my attempt to have both the hand and foot controls work. I should have figured this out before spending $100 on a hose and a few hours of my time, but 3 motorcycle technicians at 2 different bike shops failed to point out it was stupid when I explained what I wanted to do. If you do that - fit a double banjo bolt on the ABS controller and connect both master cylinders - what happens is that one reservoir pumps into the other one because the reservoir port is open when the lever is not depressed. I guess you would need to fit a separate caliper and brake line. You can have two slave cylinders (two front brakes) on a double banjo because slave cylinders have no vent.



I had previously ordered a cheap clutch kit online, as suggested by a different bike tech, but that turned out to have the wrong size fittings, and was probably too small - a small cylinder volume and reservoir - although the reservoir was on the correct side of the lever. Someone else told me that snowmobiles often have a left-hand brake, which may be another option.

I was thinking to pack a "sprag" to put through the rear spokes.

Here's my sprag - a length of aluminium rod:

Zero Motorcycles Forum | 2013+ / Running out of charge
« on: November 15, 2017, 01:34:11 PM »
Last week I'd been getting my FXS muddy and getting a bit low on charge, so proceeded to ride it home conservatively (about a steady 50kph). I started back on the road at something like 17% charge and it was steadily dropping the further I went. I'd done the math in my head to figure I'd just about make it when the bike suddenly died and went straight to 0% from 7%. It was quicker to push it the rest of the way home (3km) than beg a charge with the built-in charger.

What is other's experience ?

A few days later I made it home with 5%. Does the Zero normally drop smoothly to 0%, or fall off a cliff at some point? My Leaf starts beeping "charge now" and later the charge indicator starts flashing  with about 15km to go out of 200, with according to others even more flashing when it's really low for a final chance to limp to a charger. Of course, that's harder to push...

Update: here's a plot (attached) from the bike logs. 15:00 I rode down the highway, 15:50 I rode back up, 16:10 I played in the mud and 16:20 I rode home.

Zero Motorcycles Forum | 2013+ / Re: J1772 To Zero Adapter
« on: November 15, 2017, 01:21:33 PM »
If interested, I got an adapter from tucsonev.com for nominal $100 (plus shipping, plus import tax, plus handling fee...). Works OK, I keep in in my top box. I only have the basic charger so far. tucsonev will make up any adapter you want, e.g. dual plug.

« on: October 30, 2017, 11:46:18 AM »
I put the too-short kickstand down and as I was getting off the bike it rolled forward, fell over and knocked me flat on my butt.
There are a couple of threads about parking brakes such as one I started at http://electricmotorcycleforum.com/boards/index.php?topic=7432.0. Wrapping velcro around the brake lever seems the popular solution. I haven't yet tried to park on a hill but it's clearly something to watch for. I'm just getting over dumping mine on a merely wet road - more torque that I'm used to on my gas bike

General Discussion / Going down
« on: October 22, 2017, 10:59:35 AM »
I feel like an idiot. I just dropped my Zero FXS on the road. I've not dropped anything on the road like that for over 40 years - offroad, yes, but not on tarmac.

I'd just turned left at an intersection on a damp road, and gave it a bit of throttle to open up a gap from a car coming behind me on my right. The rear wheel spun out, got away from me and dumped me on my side. I knew intellectually that the Zero has much more torque than my 200cc gas bike, but I guess my body hadn't learned it yet. It's not the fastest or most powerful bike I've ridden - I've rented 1000cc gas bikes for a few days - though it might be the most powerful I've ridden in the wet.

Anyone else done this ?

My problem now is I don't heal as fast as I did 40 years ago; I'll have a beautiful bruise and a sore shoulder for days.  :( The bike's OK except for a bent brake lever I can probably straighten - didn't even break the flashers.

I'd love to see Zero offer left-hand brake lever as a standard option.

I installed the aftermarket one and it makes such a huge differnce
being able to put right foot on the ground when maneuvering and
being able to stop the bike from rolling with the non-throttle hand.
Any details on the "aftermarket one" - vendor etc. ? Is this a real left-hand brake (continuously variable pressure, rather than just a lock) ? Zero told me they can't offer such a thing themselves due to "regulatory requirements".

The front brake is stronger and a left brake lever would only use the rear.  You said the tire was slipping, what kind of ramp is it?  Is it just a board?
I have two ramps. One is a C-section piece of steel. That's shown in my write-up at https://www.instructables.com/id/Getting-a-motorcycle-aboard-a-sailboat/. Later I got a piece of aluminium cable tray (which won't rust and stain the boat deck), a bit shorter and steeper than the steel, with cross-members every couple of inches like the one on the left at http://s7d3.scene7.com/is/image/ThomasBetts/prod_tnb-cable-tray02?wid=600&hei=275

On my truck, there's less risk, but no chance to turn the bike around. On my boat, I could turn it around and come down the ramp forwards, throwing the weight to the front wheel where the brake is. But my experience and confidence is in backing it down, and besides, whichever way you do it, having two braked wheels offers more control.

Any details ? Zero say that they can't because of "regulatory guidelines" (US/California probably). They offer a >$600 "parking brake" which does 100% immobilization - not what I'm looking for, and seems to be  right-hand operation. (page 3-20 of the 2017 owners manual)

The bike has more rolling resistance than an ICE in neutral. Not enough to make pushing it hard but enough to keep it under control when going down a ramp.
Haven't tried the boat yet (a serious screw-up could put the bike in the water) but tried on my truck. Definitely not enough rolling resistance to make much difference on a 30 degree slope, and the handbook says not to try and use the motor to hold the bike on a slope. I'm still learning. I had it down to a fine art powering my DR200 up the ramp, but the tire on the Zero kept slipping.
