    What is everyone's revised delivery dates?

    No I haven't. But I have ridden an Alta, and the 268lbs is a killer for me. I am 78 years old, I was a young 76 when I ordered it. But it is really tough to pick that much weight up. I know, don't fall down... The conversions we are building have enough power for my riding and good newer...

    2010 CRF250 with V3

    How long did it take to bring the battery back to full charge with your 2 charger system. And how big is your generator?

    2023 Honda CRF250R with QS138 70H V3 Motor and EM260S Controller

    Your conversion looks really good. The battery is such a difficult part of every build. Also since every build seems to be in a different frame. Im looking at the battery you used, as a solution, they build a great battery. Fusible links, the right cells and quantity, they disable discharge BMS...

    2023 Honda CRF250R with QS138 70H V3 Motor and EM260S Controller

    I usually mount the motor with 3 points, the swing arm bolt, and the 2 sets of mounts at the bottom of the motor. So I just ran the mount to the front since the middle bottom bolts only go to the plate. These little motors put out some really awesome torque. I would rather be on the side of...

    Is this a good generator? A-iPower GXS7100iRD 7100W Dual Fuel Inverter

    Here is a sound test and load test of this generator. Costco had this generator last year, and sold them all. now they have them back. That is a good price. . Sound is actually good on this, pretty comparable to all quiet type generators. It only reaches 71db at close to full load. the...

    Battery construction 5,8kwh 72V

    No I haven't seen any aftermarket battery system. Unfortunately the easiest way would to replace the battery and controller. But there are very few 350V controllers. I could reload an Alta battery, but not real sure if I could get the wire bond type connection with solder and wire. There are...

    YZ250F 2014 Build With QS 138 70H V3 Motor and 450A controller Part #1 and Part #2

    I have 2 x 10A 120V chargers, since I have split my battery into 2 packs, and charge them both at the same time. 120V is available some tracks, but I have a 3500W inverter generator that can run 2 15A chargers. That brings the battery back to 80-90% in 45 minutes from about 50%. 15A charger is...

    YZ250F 2014 Build With QS 138 70H V3 Motor and 450A controller Part #1 and Part #2

    So I turned 78 last month. All is well. The YZ250F 2014 Electric is about 6 months old and it has 300-400 moto laps on it, ridden most by a older rider, but it has been near flawless. The battery packs have given me a few problems, but this is their second career on this bike. They have...

    2001 RM with QS138 70H V3 motor and Votol EM200 Controller at an Enduro

    Yes, it is for a EM260SP The Controller always says EM-100. Just lower the Bus Bar Current on the first page, and your current limiting max for Sport Mode on Pg 2. 200A or try 250A . I think it can push that much. The EM150 pushes 200A.

    Here are video.s of my YZ with and without Flux Weaking. the One that says Sport mode, the Battery was in the mid 70"s Volts, but you can hear the motor spool up higher. The One with the 2 of us, the CRF and YZ , I was in Mode 2 (66% of sport mode Amps,) but no flux weaking, it doesn't reach...

    I think Mark at XEMX1 is really on to something with this quick change battery system. XEMX1.com has more information. Ask him questions on that site.
