 Hello,
I am looking for a reliable source for a jack shaft sprocket with 19mm shaft (for Agni Motor) 12-14 tooth and must fit with a size 420 chain.
Thank you

Email dls, If you are willing to part out one of your bikes. There is a black aluminum plate that bolts to the motor and the frame on both of those bikes. It is specifically made to bolt an Agni motor to the existing motor mounts on the frame. I would be willing to pay you a worthy amount of cash for that part, if you are willing to part with it. Thanks

Thanks again Doug S. very detailed indeed. You have helped me choose my new parts with confidence. I feel I've come a long way in just a weeks time. All the answers are out there. Just have to research, and helpful advice goes a long way. Sure do appreciate it. I hope this will help others with their projects as well.

O.K so i have my Solenoid contactor figured out for my 2011 Zero Xu rebuild. I went with A Sol-600 Solenoid contactor to provide power from my 58V battery to my Alltrax 650 and A brand new Agni 95R.
 Next is mounting the Agni. I was able to find a mounting bracket From Kartmasters.com (France) I purchased it with shipping it came to a little over $60. There will be mor fab work to do to the existing bracket, but it's a good start since the bracket from Kartmasters.com allows the Agni to be mounted using the M6 mounting points on the outer edge. By doing this It will allow me to keep the sprocket as close to the shaft bearing as possible. Which is ideal and recommended by Cedric Lynch. For chain and sprocket driven set ups using the Agni motor. I could only find a few not very good pics on the web, showing the configuration of the mounting bracket on the older Zero bikes that used the Agni Motor. From what I can see it appears that Zero used the four existing M8 mounting points on the Agni motor to mount to a plate, which in turn bolts between the existing top and bottom brackets on the bike frame. It allows for adjustment of the chain tension. Can anyone confirm this? If so I see a flaw in the design, If you use the four M8 mounting points, it puts about a half inch of aluminum between the motor and the mounting bracket on the bike. The result is having to put a spacer bushing on the shaft of the Agni to compensate the correct location of the drive sprocket alignment. Doing so would cause unnecessary load on the shaft and motor, which i think would also cause more heat. Perhaps this is why the 2012 and older bikes suffered from over heating? I can't help but notice the newer Zero's modified the design of the motor mounts so that the Z54R take full advantage of the use of the shaft (sprocket seated as close to the bearing as possible with just enough clearance for the chain.)  For now it's Just a Theory, any thoughts on this?

 Update: I ended up going with the SOL-600 Main Contactor 600 Amp. Water resistant
Double-make or double-break contact
Rated load—making & breaking 600 Amps
Voltage:  24V, 36V, or 48V coil
Current:  600 amps continuous
Inrush Current 1000 plus Amps
Contacts:  Silver oxide
Terminals:  1/2" main lug, #10 coil
Mounting:  2-up to 1/4

470 Ohm 10 Watt Pre-charge Resistor
3/8" Ring Terminals
Used on 48 Volt Applications

The coil suppression diode calls for 1 amp when using 200 amp contactors, and 3 amp when using 400 amp contactor. I could Not find any specifics on what size diode for the 650 amp controller.  Alltrax Doc100-068 Spec DCX AXE Only shows Diode sizes for 7-200 amp solenoid contactors and 400 amp solenoid contactor. So calculating that there is 1 amp suppression diode to every 200 amp solenoid contactor, and 3 amp diode to 400 amp Solenoid. This should mean I should use a 5 amp suppression diode on a 600 amp solenoid. is this correct?
 This will be providing power from my 58V battery pack, into an Alltrax 48650(650 Amp) controller, in turn the Agni 95R.

Hello folks,
So I have question about solenoid Contactors. If the contactor indicates the make or break amps is 400, does this mean the contactor requires at least 400 amps to operate. Not sure what contactor is best suited for an Alltrax 650 amp controller, 58V battery. I plan to turn the alltrax down to about 450-500 amps max. Should I purchase a 400 or 600 amp contactor? Also is the three amp coil suppression diode sufficient for this set up? Or should I make my own 6 amp diode? Or could I use two 3 amp diodes in series or parallel? Thank you in advance, build on....

Hello folks.
 So I'm off to my fist Electric motorcylce build. What i have to work with so far, is a 2011 zero xu(entire bike and charger.) My mbb has malfunctioned. The bike came with a Motenergy 0810. I also bought myself an Agni 95R, which I have sitting in a box. My next purchase is a new control'r. I am looking at Alltrax because of the free software. I have not decided to stick with the AXE series, or give the new SR series a try? any recommendations? Also I was thinking a 500 amp model and turning it down to about 75% matched up with the Agni 95R? Any thoughts?
 After I get that configured I will go after upgrading that old 2011 bulky under powered battery pack. Mine still works, and charges great(for now). So who on here is building the supreme battery packs these days? (I know they don't come cheap). OR any recommendations for a tried and tested company that is custom building them would be helpful. In the future I hope to build my own, but I am not ready for that yet. For now I Just want to spend a bunch of money on a reliable high C rated battery, with a bms.( and get the looks of disgust over with from my wife asap)
 Next I will be playing with motor control software for the first time ever. I'm hoping that going with the Alltrax, simplifies this process. I guess my biggest question for the experts is, Timing and commissioning of my Agni motor once installed. From threads I have read on this site and on Endlessphere.com, and videos I have watched, I do know the procedure for timing the Agni. My question is, how much do i want to advance the timing? 58V + 400-500 amps. Does anyone Know specs as to where Zero set the Agni timing when they used to run the Agni in their bikes?
 Any thoughts, opinions, 2 cents, criticism? I'll happily accept.
Thank you for reading.
