I found this article interesting. Terry traveled 1047 miles in 22 hours and 57 minutes. Terry previously drove across the country before on a 2012 Zero S.  I believe he also added a Vetter aerodynamic package for increase range.

I had some one I work with that was an auto mechanic recommend a Craftsman 48 pc. SAE & Metric Thread Restorer Kit. Unlike a tap and die set it should roll the treads back instead of cutting them off. I tried this on several repairs and the nuts and bolts go back on as if you were using new hardware.Here is a link to the one I bought from Sears.http://www.sears.com/craftsman-48-pc-sae-metric-thread-restorer-kit/p-00942275000P#

Here is a link to a guy that had a bunch of belt noise on a Corbin Sparrow.  He started using a pure PTFE (Teflon) aerosol spray from Kano Laboratories but then found a 1/2 inch squeeze of Radio Shack Teflon Lube Gel to work much longer.http://www.los-gatos.ca.us/davidbu/sparrow/s_diary.html

"Yes, you have peak voltage and rms voltage (or ave voltage) by PW modulation. Same with current."

RMS and average voltage are not the same. A normal voltage meter reads average voltage (0.636 x Vp) and assumes that it is a sine wave at 60 Hz.  It is calibrated to display the RMS voltage (0.707 x Vp).  If this was not the case there would be no need for True RMS meters.

Zero Motorcycles Forum | 2013+ / Re: Changing the front sprocket?
« on: August 12, 2013, 06:08:29 AM »
Degigner Dan, I work with a lot of sprockets on large motors.  Typically the bolts you pull off to unlock the sprocket get put back into the other holes that look like spare holes. By tightening the bolts in the other holes the sprocket normally pops right off.  If this is not the case a gear puller may be better that trying to pry it off. I would not put heat on it if there are any bearings or seals that the heat could conduct to.  Liquidwench penetrating oil is always worth a try.

With regards to servicing the Mission R this article said "Getting one repaired is like fixing your Rolls-Royce. Send the company an SOS and they’ll come to you wherever you are, with the necessary parts and fix your bike. For free. "

Zero Motorcycles Forum | 2013+ / Re: Extension cord too long?
« on: June 12, 2013, 05:49:34 AM »
It appears that I was wrong with my above post and Trikester was correct.  I have seen a 100 foot 15 amp extension cord get very hot while coiled on a reel.  I was told by an electrician  that it was because of the inductance and I always assumed that was correct. With a little research I found recommendations of reducing the current capacity by 25 to 50% if coiled but most information refers to not having the cord coiled for a safety issue.

People that buy 100 foot 15 amp. extension cords like to put them on a reel to easly wind and unwind them.  If you use a 100 foot 15 amp cord while it is still on the reel it lowers its current capacity to about 7 amps.  This is due to the extension cord now acting like a coil and creating a larger inductive reactance (AC resistance).

Zero Motorcycles Forum | 2013+ / Re: Battery life
« on: June 11, 2013, 04:12:56 AM »
Nissan lists the following as factors that could degrade battery life.

Frequent use of quick charging
Frequent charging when battery state of charge is already high
Too much electric consumption while driving
Long term parking with high state of charge

It appears from Plug In America’s LEAF Battery Survey that a high average temperature could also be a factor.  I believe some one mentioned this here before.  Here is the survey PDF link. www.pluginamerica.org/surveys/batteries/leaf/Leaf-Battery-Survey.pdf

Zero Motorcycles Forum | 2013+ / Re: Surprised by lack of LEDs
« on: June 08, 2013, 07:09:14 AM »
I would not get so excited about LEDs right now.  There are a number of manufactures that are overdriving the LEDs to get a desired brightness. They also say that it will replace a certain wattage incandescent bulb even though it does not put out the same lumens (light output). Many home LED bulbs have a similar efficiency as a standard compact florescent bulb.

I had some high intensity LED landscape lighting from Westinghouse that had a 1 year warranty. After 2 years all the bulbs appeared dim. I figured if the LED should have had a 100,000 hour lifespan it should have lasted over 22 years at 12 hours a day average. I pulled the bulbs apart and found that they were running the LEDs at 35ma instead of a normal 20 ma.

Very few of the LEDs actually burned out but they all became dimmer ever so slowly. This light dimming might be able to be check with a light meter.

The more that you read about LEDs the more you will see that some manufactures are trying to include a heat sink.  The problem is that not always is the heat sink of the necessary size or shape and fins that are position horizontally will heat the fins above them instead of convecting the heat away from the bulb.

Zero Motorcycles Forum | 2012 and older / Re: Post Sandy in NY area
« on: November 06, 2012, 08:53:50 AM »
This sounds sweet if your power stayed on.  I am in the Philadelphia PA area and lost my power for 5 full days.  They were estimating that it would be 8 days.  Everyone was throwing all of their food in the trash after 3 days. There were no flashlights of any kind at any store.  I am thankful I did not have an electric hot water heater. The temperature here was going into the low 40s at night. I had a 1750 watt generator that made life a lot easier but I still needed a wood stove running for heat.

This would have been a little easier without a wife and kids. I am sure many were not prepared.  I know I learned a lot of lessons.  It really makes you think what others not so fortunate went through.

Zero Motorcycles Forum | 2012 and older / Re: 2012 S ZF6 - Power rating
« on: October 17, 2012, 02:05:22 AM »
I think you also have to look at the voltage that the motor is running at. Here is a link to a motor that is 30 hp at 72 volts, 54 hp at 96 volts and 62 hp at 120 volts. 

http://www.evdrives.com/product_p/mot-es-31b.htm

Zero could easily change the voltage of the 2013 battery packs and run a very similar motor and achieve these huge increases in hp.  This would mean that if you could get a 2013 motor and put it into your 2012 bike that you are not going to get 54 hp unless you could increase battery voltage.

One thought here could be that Zero might have 62 hp for 2014.

Found another review at http://www.greencarreports.com/news/1079595_2013-zero-electric-motorcycles-bigger-badder-faster.  What is interesting is they had a little bit more info on the Bluetooth connectivity.

“Bluetooth, fast charging smarts
Also new for 2013 on all Zero motorcycles is a smartphone bluetooth facility that lets iPhone and Android users tweak elements of their Zero motorcycle’s riding characteristics from their phone.
This includes modifying top speed, regenerative braking characteristics, and acceleration, as well as provide diagnostic information and other important motorcycle data.
When docked in a suitable cradle, riders can even use their smartphones as a secondary dash, providing additional information about their Zero motorcycle while in use.”

I was also wondering if Zeros 54 hp motor is the same as Brammos empulses 54 hp motor. I found one that was 54 hp at 96 volts, 30 hp at 72 volts and 10 hp sustained.  It seems smart that they put a nice heat sink on the motor.

I think the real winner in this year’s line up is the FX ZF5.7.  It looks like Zero insiders from elmoto.net are really excited about it and are buying it themselves.  The other thing I see is it could grab sales from the XU and DS brands. The FX 5.7 is $1500 more than the XU 5.7.  This seems like a worthwhile upgrade.  The FX 5.7 is 88 lbs lighter than the DS 8.5 which is 66 lbs heavier than the 2012 DS ZFF6. I read about trikester not wanting the extra weight in the dirt. The DS tires look more street oriented than dirt/street oriented.

The Zero website just changed again to show the 2013 models much better.  It is very professionally done.  I really like how you can quickly change screens between models and click on bike colors to see the bike change.

I like that they are not exposing the battery charger on the XU to wheel debris anymore.

I was looking at the high res pictures and it appears to me that Zero may have fixed the problem with the mirrors also.
