Re: 1979 Yamaha XS750 conversion.

Try turning that rectangular mock-up on its wide side, then leaning it down in the front of the frame. That will give you a better, lower center of gravity, and leave you room for the motor behind and slightly above it. The motor is a hub motor, so there is no advantage there, but a lower center of...

Re: 1979 Yamaha XS750 conversion.

Also, here are some pictures showing a cardboard mockup that is the size of my battery floating around in my frame.
I'll need to make a box for this to sit in, but this looks promising so far.

Re: 1979 Yamaha XS750 conversion.

Nobody local had anything available, so i ordered a Yamaha fazer swingarm. $_57.jpeg I hope it fits. Some other conversions from shaft to chain for the xs750 used this swingarm, so fingers crossed that it will not require much modification. We'll see. It should get here pretty quick, it is only goin...

Re: 1979 Yamaha XS750 conversion.

I have been contacting a few suppliers from china about getting brake parts that will fit. I will post here with some more info when I have confirmed a fit. But now for those other photos I promised earlier! Here is a picture from the day I picked it up: TuojwY2-min.jpeg I fitted one leaf module var...

Re: 1979 Yamaha XS750 conversion.

I had considered using a throttle setup like that, but I have (possibly unfounded?) reliability concerns because the stock throttle is not dual cable. This is the motor: https://www.qsmotor.com/product/17-inch-12kw-hub-motor/ I don't have a model number. For variable regen, I plan to use some kind o...

Re: Chinese E-Vader/E-Grom/E-Monkey

Well that was short lived.
My order got cancelled and the vendor no longer lists the bike for sale.
I decided to go ahead on my 1979 yamaha xs750 conversion with a 12kw hub motor.
Ill make a different post about it.

Re: No Throttle response on Egrom when Overvolt

While one would assume you'll wind up with a bigger fuse, I'm curious to see what happens if you leave that fuse there with the bigger controller. It's not like you have another use for it after you burn it out. I was thinking of removing the fuse as it is not present on the older models and just s...

Re: E-Grom Clone 72v battery upgrade recommendations

I just ordered one of these (the grom clone) and I already have a pile of leaf batteries.
I am planning to do this same upgrade when it gets here to get better range than stock.
Did you ever get anywhere with this upgrade?

Chinese E-Vader/E-Grom/E-Monkey

I just purchased one of those Chinese 2000W mini bikes that go by various names such as "E-Vader" or "E-Grom" or "E-Monkey". The one I ordered claims to have LifePo4 batteries rather than the normal lead acid ones. I plan to do a very detailed review of the unit, and post a lot of the information th...
