A few years ago when a deer decided to commit suicide in front of me, I obliged & rode through the debris field.
Fortunately it was a young buck & my speed was down so I was able to keep upright. 
When I assessed my situation I found I was mostly ok but my phone had decided to leave its mount. Another good fortune was that when I circled back I found that the phone had survived quite well.

Here’s the mount….

When the iPhone 15 came out with auto 911 summons my wife insisted I give up my trusty old  10 for the 15.
Fast  forward to today on the way home in the poring rain I happen to look down at my phone & all kinds of activities going on.
Apparently the phone had slipped down in the side pinching mount & managed to double press two opposing side buttons & call 911 (a selectable feature).
Anyway, two strikes & it’s out. 

Anyone have a handlebar mounted holder that’s easy to use yet secure.
Not looking/needing vibration resistance as it’s for my 2016 DSR.

TIA

General Discussion / Deer Me (Incident Report)
« on: October 01, 2022, 09:48:43 PM »
On Thursday AM just before 1st light, an adolescent buck decided to commit suicide in front of my Zero DSR. 
He was successful & I manage to ride through the debris field without going down. 
When I came out on the other side I heard a heavy scraping noise.
I thought for sure I was dragging a corpse.
Turned out to be the left crash bar (deer approached from the left) that had its 10mm bolt sheared off as well as one of the skid plate mounts dislodged so the top of bar was what I had heard.
Looking down at the dash I found the wind screen & instrument panel tilted steeply back.
My left mirror was missing as was my phone!!!! (I think the windscreen made contact with top of phone squirting it out the bottom of the holder).
Initially I thought one of my fork mounted driving lights wasn’t laminated but after dismounting I found that the right one was pointing down & the left was pointing up.
The fender was missing as was the headlight housing.
Sometime back I had installed a JW Speaker adaptive 5.75” led headlight and it survived quite well though was pushed in & to the left due to the (stock) headlight mount being mangled.
I had carved out the stock headlight housing to allow the led headlight to fit. 
I made it out fairly well but my knees.
My right knee received quite a deep gash from (I believe) the accessory plate on the right crash bar in spite of my very expensive Motoport ridding suit It seems the plate sliced right through the armer & then had its way with my fleshy knee (deep cut that took 10 stitches).
My left knee felt as if it had experienced a hyper extension.

If you have crash bars on your bike you may consider removing the backside of that accessory plate on the right bar.

Careful out there

The front brake on my 2016 DSR seems to have excess drag & I'm thinking a rebuild is in order (72k miles & 4 or 5 pad changes). 
It’s my understanding that replacement parts are hard to impossible to obtain.
Does anyone know where to get rebuild parts?
Anyone upgrade to Brembo?
TIA

EV Ownership in these troubling times.
I live in Southern California & gas is marching towards (or past by now) $6/gal. 
Very thankful to be an EV owner right now.

By this I’m referring to letting the onboard charger go to 100% and then shut off thus insuring cell balance has occurred.

Back in July of this year my 2016 DSR battery was changed under warranty.
I decided to try and keep the SOC of the new battery in “the sweet spot” so have limited it to around 80% max.
I now have 4,563 miles with only 3 charge cycles (1,110 miles on the last one) yet presently  @ 83% the cell balance is 2-3 mv.

I’m thinking letting the charger go to 100% so cell balance can happen is not necessary or I’m I missing something?

Zero Motorcycles Forum | 2013+ / Battery charge level sweet spot?
« on: August 27, 2021, 09:21:18 PM »
A few month ago Zero replaced my 2016 13ZF battery as it had lost substantial capacity. 
The new 14.4 is a HUGE upgrade as my old battery was quite capacity impacted. 

I use the bike to commute about 55 miles/day so in the 4 years of ownership I managed to rack up nearly 60k miles (I purchased the bike @ 1yrs old & 2.8k miles).

My old charge strategy was to plug in at work & unplug at end of shift (100%).
I was able to return to work on that charge & would only supplement significant of additional miles were added to that day’s commute.

I need to maximize the usefulness of this new battery so will limit its charge/discharge levels.
My commute consists of mostly high speed ie fast drain so I’m sure that’s a major factor.

Perhaps it’s best to keep the battery in its mid state as much as possible which means charging at work as well as at home but limit charge to say 70% & discharge at 35%.

What say you?

PS, over in the Parts, Mods And Hacks section I’ve started a discussion on how to limit charge level (input there also appreciated).

Parts, Mods And Hacks / Means of limiting charge
« on: August 07, 2021, 07:54:09 AM »
A month ago the my 06 DSR battery was replace due to insufficient charge capacity.
My old charge pattern was to plug in upon arrival at work & unplug @ the end of my shift (with 100% SOC). I figured this would be ok as it would only be @ 100% for a short time.
I only needed to charge at work (tho often arrived at work below 10%).

Now with a battery 10%  greater I’m changing my charge strategy.
I have a 6 hr spring wound timer that I’ve corded up & using to (try) for 85% SOC.
This allows a buffer on both stream sides of SOC.
I’ve read that this is best for battery retention level.

The problem is that I need more then the 6 hrs & have to add time to the timer sometime during the day.

Ideally I need an 8 hr timer but can’t find one.
The next size up is 12hr & I’m concerned that the resolution won’t be adequate.

Any suggestions?
Has to have contacts rated for 15a

Thx.

52k miles & each winter seems to yield less from the battery but not seeing a drop in range but rather seemingly a reduction in intensity. 
I use the bike to commute to work (about 55 miles round trip) & charge at work.
Not noticing this on my afternoon leg home but that’s due to relative warm temps & high state of charge.
I arrive home in the afternoon with about 72% charge and the next work morning return on the remainder of the charge arriving at work with about 30% & then plug in for a full recharge by shifts end.
I’m finding that with the cool AM commute battery output (amps) increasingly reduces but it seems each winter it’s more noticeable then the last. 

As stated, range has not appeared to be drastically reduced as top speed is reduced & thus energy is saved.
Flat terrain is not too bad but much speed is lost when encountering a grade.

I’m assuming this is a battery issue as apposed to a BMS issue.

The bike will be 5 years old next June so I intend to have the battery condition assessed @ Hollywood Elect. before the warranty is over on the battery.

Any feed back would be appreciated.

Thx.

2016 with 50k mls....

I just got a new 912/921 led (Running Light)  to replace the last one that has ceased to function on all chips.
The new one is slightly larger OD then the headlights opening so I enlarged the hole with a Dremal & file.
This left some dust inside the housing plus I noticed some fine white hazing on the main beams reflecting surface. 
I flushed out the inside of the housing with water & to my horror much of the silver coating is now gone >:(

Just a heads up to those tempted to clean their housing.

Likely will just end up spending the $150+ on an OEM replacement as that’s the fastest/most assured positive outcome route but asking for input on an aftermarket replacement. 

I have lots of aftermarket lights & even a garage door remote that resides in the headlight housing as does a power port for my phone so needs lots of space for these if an aftermarket solution.

Parts, Mods And Hacks / IEC320 C14 Panel Mount Plug Adapter Replacement
« on: September 24, 2020, 06:22:46 AM »
About 15 months back I was seeing that my charge socket was heat damaged. 
I contacted Hollywood Electric to see about procurement of a replacement (I figured OEM would insure the highest quality as I was/am leery of standard crimp electrical connections when the amps exceed 8 amps. 
I’ve seen plenty of heat damaged connections during my HVAC carrier.

Harlan said that I was (just) under the warranty period & that it would be covered. 
It’s was replaced but that didn’t stop my worries for a reoccurrence.

Gradually I’ve felt the back side of the socket becoming quite warm during charging.
Well, a few weeks ago when I went to plug in the charge cord to the socket, to my dismay I found one of the sockets pin stuck in the socket of the cord!!!!
I plugged in & monitored the temperature.
Turned out it was acceptable so I was able to continue commuting while I sourced a more robust solution & had time to replace. 

I found this plug on Amazon
Viborg AC 250V 10A IEC320 C14 Panel Mount Plug Adapter Power Connector Socket Screw Mount 3 Pins Inlet Male Power Plug Socket Audio Grade (Rhodium Plated, Black) https://www.amazon.com/dp/B01N6M3CHF/ref=cm_sw_r_cp_api_fab_Kb-AFb9X67HXG

I like that it has compression screws rather then the usual 1/4” crimped flag connectors. 
I found that this plug is a bit larger in the dimensions that mate to the bikes frame so had to remove material as necessary to fit.
I was able to cut the last 1.5” of the cable leading from the old connector & then cleaned up the individual wire strands with some sand cloth.
I pre positioned several layers of heat stink (note that the OEM used glue lined heat shrink but I didn’t have that type so used sealant injected on the wire end before shrinking to help insure no water migration).
I was able to double up the wire into this sockets junction points.
I inserted a small piece of copper between the setscrew & the wire to protect the wire as well as distribute the pressure from the setscrew. I was careful while tightening the screws as I had read a review stating that the Phillips head strips easily.
Getting this socket to fit into the bikes frame was a challenge due to the fact that the wires go back from the plug, not 90° like the OEM.
I abandoned trying to get the M3 .5x8mm screws to work & instead ordered m3 .5x25mm threaded rod as well as flanged m3 .5 nuts from McMaster Carr (delivered to my door less then 21 hrs later).  NOTE that the nuts require a 5.5mm driver that will have to be hollow if rods aren’t shortened or standoffs used).

[Edit: NOTE 7/32” is close enough to work as a driver or in my case, box wrench]

Space is VERY limited & this work can be frustrating so not a task for the weak at heart. 

I used blue thread locker on the rods & fully screwed then in via dbl nutting.
I found a small tube that I put over the screws so I didn’t have to struggle screwing down all that distance. 

It turned out well & Im hoping this ends my overheating charge cord/socket situation.

General Discussion / Hollywood Electrics during LA’s civil unrest
« on: May 31, 2020, 08:10:19 PM »
Part of yesterday’s civil unrest in Los Angeles occurred in the area that Hollywood Electrics is located (& also my 95 yr old Aunt).

Anyone know how the store faired with all the looting?

45k+ miles on the clock. 
It’s only happened a handful of times but twice this past Sunday. 

I have a 2003 BMW R1150RT and it experienced the same condition.
Turned out to be a total severing of the power inlet wire into the ignition switch. 
It was due to undue stress due to the way the factory zip-tied the wire loom.
It was a common issue & fortunately the bmwst.com community was able to give me tips on how to disassemble the ignition switch so I could make a sound repair (had to replace the wire as not enough length to splice).

I’ve not yet dig into the problem on my Zero yet (is not too great of an issue at this time & doesn’t readily show its self).

It’s happened mostly backing out of its parking spot in the garage that involves full handlebar lock (CCW) as well as full decompression of front suspension.
It’s as if full/all power is being cut to or from ignition switch.
All lights die but then reappear a second or so later.

Anyone else see this issue?
Not much re ign switch in the unofficial manual.

Any tips/insight including ign switch info appreciated. 
TIA
