650 Twin - Interceptor/GT / Re: Out and about on your 650 - photos

It's fun to ride. I think the best part of the parkway is from Cherokee to Boone. That is where most of the tunnels are and going through the mountains. The portion in southern VA is pretty boring. So getting off and hitting side roads there was probably a better ride.

I live about an hour south of the parkway but too far away to ride the best part of it in one day. I can make it to Boone from where I live and back in the same day. One year I for vacation I rode the parkway end to end. Planned on doing skyline drive but it was pouring rain for the first two days so I delayed starting and missed out on skyline drive.
Yeah I definitely heated the brakes on the Outback to their limit on some places like Grandfather Mountain, down around in there. Plus it also was pouring rain in some spots. And then sunny in others. Sun showers are so great in that part of the world. Jealous you're in that prime riding country!

I expect to be in the general area. I have a short out-of-state work trip, but I expect to be back for the weekend. Trying to work out logistics with a riding buddy, my wife, non-riding friends, but I will be in Fredericksburg on Saturday and possibly Sunday. It's one of the bigger Oktoberfest deals in the region, so make sure you are aware of that.

Yeah, will likely not do Fredericksburg itself for just that reason. It's crazy enough there on a weekend as is, let alone Oktoberfest. Then again, it's ACL weekend #1 here in Austin, so not doing anything in town here either....

I don’t suffer from magnetophilia  ;)

Cyrusb,

The extra spring was fitted because the gearbox was very new and tight when I bought it. I suspect it might have come from a brand new bike and possibly removed under warranty, because of a fault. On down-changes, despite my later efforts to ease everything off and four or five reassemblies, the pedal wouldn’t reliably come up far enough to reset the spring loaded finger which engages the cam plate, so it wouldn’t change down below third. I changed the existing return spring but it made no difference. It was irritating to have to play the soft shoe shuffle to avoid finding myself trying to pull out from junctions in third or second. I’ve put about twelve thousand miles on it now and it might have eased off, making the helper spring redundant but it’s OK as is. It’s easy to remove it and the only clue it was ever there would be the M5 tapped hole in the pedal.
Ah! I feel your pain. I had a stiff shifter and kicker arm after I did the right hand conversion. I had to leave one of the two "locating?" dowels out and it works fine. Still kicking myself for not just boring and bushing my stock cover. In fact after I received the kit it was obvious all the parts were already there with just a little lathe and drill work.

Very cool!

I have never touched the idle adjustment of my 2011 Bullet. According to the digital tachometer that I installed on my bike it idles at between 1100-1200 rpm when fully warm. BTW, I see 3900 rpm at an actual 60 mph.
That's useful, so about 5,500 at 70mph. I got mine up to over 80mph indicated, about 6500 to 7000rpm. That is a bit much for our single, I'd say. Which front / rear sprockets do you have?

Those are your videos?
Looks like fun.
I would like to find one just for cool factor.   1st world problems.   Lol...

You could always fit an empty-bodied magneto for decoration, the gaps in the crankcase casting for the magneto strap will still be there.

Here is a link to a 15-minute-long YouTube video of a fellow riding a Royal Enfield diesel model along the Roman Road. After watching that video and listening to the diesel exhaust I decided that I wouldn't want to ride one of those things anywhere:

A truly efficient and simple AC motor would need three phase power.
The brushless motors that are used for hub motors are running on chopped up, PWM DC, not true AC.  Some controllers will run at higher frequency to create a waveform that approximates AC, which gives quieter running and more efficiency, but the run of the mill controller just sends subsequent square pulses to the various phases.

There's some information on how this works here:  https://www.integrasources.com/blog/bldc-motor-controller-design-principles/

One could build a controller that had more phases, but I don't see much advantage.  The motors are already constructed with lots of poles which gives more power pulses per rotation.   I count something like 48 on the rather basic, gearless hub motor shown in this picture, split between the 3 phases:  https://www.ebay.com/itm/Voilamart-Electric-Bicycle-E-Bike-26-Front-Rear-Wheel-Motor-Conversion-Kit/322247604604

In this design, the stator is fixed to the axle, while the magnets ( not shown in the picture) are attached to the rotating rim of the motor.
I think it's easy to see why this basic design of hub motor has a hard time developing power at low rpms.

The type with internal gears can spin a lot faster at a given wheel rpm, producing the same power with much fewer poles and in a package with reduced diameter and weight.   http://volto.co.nz/wpvolto/wp-content/uploads/2018/06/motor300w-electric-bikes.png

I imagine that the motors used on the Sol and Sondors machines both use internal gearing, but I haven't seen details of these.

That's pretty funny, as the bear urine was likely sterile enough to drink directly, as the bear would have been dead otherwise. Maybe she carries a still around? Living proof that "booksmart" isn't necessarily a survival trait. Apparently she didn't know about canteens or water bottles...but she's got free room & board now.

The Cal Fire officer who arrested her also said he believes there is a high possibility that she additionally started a separate vegetation fire the night before the Fawn Fire broke out in the city of Shasta Lake.
Souverneva faces a felony arson charge with an enhancement of committing arson during a state of emergency, according to Shasta County District Attorney Stephanie Bridgett. She could face up to nine years in state prison.
On Monday, Governor Gavin Newsom proclaimed a state of emergency for Shasta County to support the response to the destructive Fawn Fire burning north of Redding.
The fire — which started on Wednesday, possibly at the hands of Souverneva — has so far consumed approximately 8,577 acres and was 60% contained as of the latest Cal Fire update Monday evening at 7 p.m..
So far the Fawn Fire has destroyed 144 homes and other structures, causing thousands of residents to be evacuated from the area. However, improving weather conditions and cooler temperatures allowed fire crews to make progress over the weekend, raising containment to 35% as of Sunday morning.
The fire at one point threatened 9,000 buildings but the number dropped to 2,340 on Sunday. The light rain that fell periodically over parts of Northern California on Monday was also helping the efforts to contain the fire.
