Thanks.

Hey Vince, there was another thread on here about the EBMX x9000 V3. The contact over there is a friend. Bridger Hombreverde at support@ebmx.com he has a KTM Freeride with a QS138 70H V3 and the X9000

Thanks for the reference Philip, but Vinsanity and I have been talking for quite some time about this problem and others. My Far Driver Controller experience is limited. So Ryan Goodyear is a good answer. I corrected my problem on my Votol EM260S controller by replacing it. There must have...

A friend works in Support at EBMX . He said send a request for the pinout to Support@ebmx.com and he can send it to you. He has also asked ChargedCycles when will the Harness be available, he just sent it and is waiting for a reply. Good luck Don

I have actually tore apart a Stark battery. The cells are now propelling my KTM DIY Electric Dirt Dike. They are not easy to take apart, but you can find defective batteries around for about $500. The complete package, like above, is probably worth somewhere close to what he is asking. Here...

Some thoughts, I understand that you are a good fabricator, but I would recommend not to cut and reweld the main frame. Welding in new mounting brackets is OK, but the Integrity of the frame is a tested thing. I have seen modified frames fail. The factory have a lot more engineering in their...

It looks like Honda is copying my KTM Duke 790 build...

I am glad I helped you get interested in building an electric dirt bike. You look very thorough in your plans. You look like you want a lot of power and will ride this really hard, Have you ridden a Stark yet? I have and quite often can and do, but I cannot use all the power on it. I am...

I have taken the cells out of the Stark battery. As mentioned before THIS COULD BE DANGEROUS, OPENING A BATTERY LIKE THIS CAN BE DEADLY, IF YOU ARE NOT TRAINED, OR IF YOU MAKE A MISTAKE...WORK ON THIS AT YOUR OWN RISK I worked for 50 Years in the XRAY / NUCLEAR and MRI Medical industry, on the...

I have tried a few spot welders, and was never really happy with the welds, or I couldn't get penetration for the thick bus bars. I also saw that Alta, Stark, Chi Battery Systems and others, all had fusible links on every cell. Here is an early video of how we made fusible links. Since then...

If you look at the complete open battery above in pic 5931, you can see the bottom tray. The bottom tray wasn't complete in pic 4352, and those batteries were from a KTM Freeride (There was another row of cells on top of the flat group already there.). I could only make it 20AH 72V for the...

Yes if you build one of these, you will be building 5 or more. I have a lot of friends, that I helped them build one, or built one for them, that have built a bunch more. So go get the welder, and start learning. Get an inexpensive MIG welder, 100-120A, one that accepts gas. Start with that...

Hello Mr. D_Daly, welcome to the Forum. Yes your bike works perfectly for this type of build. Go to post #11 in the article, (Your post is post #26), the first picture in that post is a "90's model that I build. A bit different in the motor mounts and a simpler shape for the battery. The...

This all bids more questions??? I have run the QS138 70H V3 motor almost exclusively. With the EM150SP/2 for smaller bikes and lots of EM260SP/2 and EM260S controllers on the full size bikes. I am dabbling with the FarDrivers now, but no real experience yet. I have never overheated the motor...

Mike Burkeen, of the AMA, spoke with Steve Agular today with some great news. They are going to have an Official Electric Class race included in the Washougal, WA, AMA Pro Motocross weekend during the Amateur days of the event. There is also going to be a Open Electric Class at the Mammoth...
