Bleeder resistors are used and the only problem with using them is, every time the device is turned on there is a high-in-rush current sent to
the cap(s). A high value supply resistor is used in used around a power relay that supplies current to the cap(s). Some equipment depending
on the application like a HP transmitter used a delay circuit for applying voltage to the caps which bypasses a resistor that is across the relay
contacts. When the delay relay times out the relay contacts close and the caps get the full voltage applied to them without the high inrush current.
A DC supply system is easier to work with versus an AC supply. I am sure the controller has a safeguard circuit built into it for protection.
Good stuff Dennis and though this controller is not the best quality the safe circuit did work and since I ride the hybrid often I'm glad it's not down awaiting a new controller.

Advice I can take!
I forgot those old CB days, the Linear Amplifiers plus all of the old tube amateur transceivers, including audio tube amps, all have HV DC/AC
on them for operation. The old hi-power broadcast amplfiers will KILL You! I also want to say that the CDI systems on cars, etc, charge a
HV capacitor to 400 vdc and if you get across the output of one of them you won't forget it! At a low votage of 25 vac 60 Hertz is lethal and
anything above that is deadly. AC will stop your heart rhythm (big hazard) and HV DC will burn you and throw you across the room!

Got the hybrid figured out & running well, was way too rich without the expansion pipe. For daily riding I only carry one battery on the bike two for longer rides. The 66cc lost some low end performance with the pipe change but the electric can be used to more than offset the loss. I have a 36t rear to clear the disk brake setup so using some electric power during acceleration is huge as is hill climbing. I underestimated a hill yesterday and didn't have much speed built up to climb it but I used both motors till I got the revs built up to finish with just the gas engine. With the expansion pipe this would not have been necessary so yeah low speed torque is down with the kit pipe.

Using the electric for starting really beats pedal starts or kick starts for that matter and this 36v will get almost 30mph on it's own. One oddity with the hybrid that I reported before was that the bike vibrated enough to cause an audible buzz not enough to really feel but easily heard. I think maybe that's gone but not really certain how fast I was going yesterday. I'll mount the speedo and try it again.

If it’s coming from the hub it could be the sound of it run by a squarewave controller.

Thanks Tony. It is a hub setup
I've not run it up to a speed at which the vibration comes in as of yet. Before the battery switch about 40 mph and above and this while under gas power or with a combination of gas/electric. As this CG has been modified a lot speed on gas is well over fifty, but I seldom cruise at speeds over 30 mph. With the 36t the motor just loads at 30.
If I find the vibration is still there do you think I am causing damage to the hub motor?
Thanks for your insights as I know you have a lot of insight into electrics/gas bikes in general and hubs in particular.

BT forum pretty quiet for a couple of weeks so checking in on what's up in my world. Tornado last evening missed us by 8 miles, long track mezzo cyclone style which though it lasted about 8 hours did little damage to cities in it's path thank God.

Rode the hybrid Grubee this morning, really nice out. The stock muffler broke off at the can just leaving the pipe. This was a first for me. I had taken the Thrust expansion pipe off and replaced with the old kit muffler in order to run saddle bags to hold my batteries on the rear rack. The Thrust pipe interfered with that configuration thus the pipe switch. The change was noticable on the low to midrange performance which was expected. Not a huge deal but noticable.
When the muffler fell off I decided to just keep riding and see what change, if any, could be felt. I had the GPS mounted, but not the tach. First test was a 10 degree hill, it being the steepest incline inside the city limits. Dead stop at the bottom pulled straight up, not a problem even with the tiny 36t sprocket; no pedal or electric assist. Then off to a flat just outside the city limits for a quarter mile run up to 40mph. I again was surprised at the ease it came up on power band, which I was struggling to get to with the stock muffler just a couple of days prior. I shut it down at 40mph but it was just getting started. This bike with the Thrust expansion chamber has seen mid 50's and with a Mx 80 chamber low 60's. This motor comes on pipe at 5,500rpm to 6,800 rpm depending on which expansion pipe is used and runs out to around 12,000 rpm from a dead stop more than a half mile is required. I'll mount the tach and wear some safety gear to see what he short pipe can reach. I'd be shocked if it actually performs well, but it felt and sounded really good in the cool air this morning.

This 66cc motor is a reed valve, Delloto carb induction with my own window piston and extra port, jug design. Head is a 6cc after market with copper head gasket and a single base gasket. Though I've never dyno test this motor I feel it must be at least 5hp. I base this on how it feels compared to another motor I tested in this frame which dyno test over 8 hp. It was one serious port timed China girl that one day I might rebuild, the jug is all that it needs, but the case needs to be cracked open to remove the debris from the ring that broke.
The current motor has a ton of hours on it and still runs fresh, way past 10,000 miles for certain. GT5 balanced at Bicycle Motor Works seven years ago and shipped as a port timed motor. I'm convinced balancing is a key factor in motor longevity with the CG motors, regardless of the brand. Running an aftermarket aluminum head and avoiding high compression ratio ensures good cooling which is also critical to these motors. Finally running a reed setup with piston window lubricates the wrist pin with a cool charge of fuel extending the motors life as well as helping with power, if set up properly and carefully tuned. Reed systems typically are not just bolt on power; you have to work for it through tuning and testing and this depends on the motor. I have two identical motors set up the same with reed valves one runs really well the other not a lot better than stock. I never went the extra mile to tune the second engine just copied the exact setup of the first. Shame on me that didn't work! It's setting on a shelf as a backup, but if ever need I will tune it properly.

I like all types of motors 4 stroke, 2 cycle or electric and have a lot of good things to say about all of them yet the typical kit China girl requires some real patience and experience to get right on your own. Using a quality vendor like Norm at Venice bikes, for example, is a good place to start.

Tony the vibration seems to be gone, at least at 40mph, wish I knew exactly what eliminated it, but I tried several small things at one time and it's gone.
One thing I noticed was how much an extra 750 watts was felt at 40 mph. One hp added at that speed was like an extra gear. I only used it for a couple of seconds or so, but really dramatic effect. It's a 36v hub that by itself is only able to pull 20mph or so as this bike is over 125 lb and not a lightweight for sure

Hybrid update since I've ridden quite a few miles since my last post here in October. The low end to mid range power loss with the CG engine is more than I first thought but the electric hub offsets this loss well. No problem with top speed using the gas motor only it easily goes past 40mph and this is faster than I ride by 10 or 15 mph typically so actual top speed with this setup and for my use don't actually matter. I really like riding the hybrid in town because of the many stop signs at which I always stop (really) and from a dead stop I rely on the e hub by itself to get me rolling. No pedaling or clutch slipping from a full stop even on serious inclines.

The electric hub "vibration" no longer occurs so the changes made a difference. Exactly what made the vibes? I've no idea at all, but it's history.

Weather here is about perfect and has been all Fall with more of same for next 10 day forecast. Best Fall weather I've ever seen in Indian Territory!

So rides are always comfortable.

Dead still and 67 degrees so a 5 o'clock ride is in order

Howdy, I have one of the bikes I built as a 50cc 2 stroke & never sold it. Brand new & now everyone is ebike now days I just kept it. I have a 36v 500w front wheel kit 26" I never used so I put it on the bike. Being lazy I use the electric kit to get to bike moving fast enough I can just let out the clutch to start it. At 67 I don't even feel guilty. .trk

Good to hear from you Rick, we are all on a dry spell forum content wise.
Pete is holding his own content wise. Another masterpiece.
Steve may have got flushed into the Strait of Georgia.
Mona got out of hospital a week ago this last Monday. Hickup in her cancer chemo management got her RBC count dangerously low. Took a week for the wise guys to sort it out. It took two units of blood to get her out of the hole. don't know who the doner was, but Mona is starting to look like a 75 year old Farrah Fawcett. (^)

Good to hear you're getting plenty time in the saddle Rick. I've forgotten what a ride-out feels like. Plan was to take my BLUE BAMBOO electric for a spin last Saturday a.m., but Storm Arwen hit us late Friday night and left a trail of devastation in its wake... so no ride. Alnwick front street looked like a war zone movie set what with all the blown off roofing slates/tiles, disloged pieces of masonry, damaged vehicles and downed trees. Half the town's Christmas lights were nowhere to be seen. Suffered a 3 hour power cut here Saturday a.m. but power to half the town was only just restored after five days yesterday afternoon. Went online to read/view reports of the storm's aftermath on YouTube and that's when I saw the videos of the far worse flooding situation Steve must have endured up in B.C.. Hope things have started to dry out there Steve.

Glad Mona's turned a corner with her chemo Tom. I'm managing to stay on top of Jen's care with the help of twice weekly home visits by the district nurse team who pop in to change the dressings on Jen's foot and b'donkadonk and assess the wound's (slow) progress. The nurses take regular photos of Jen's wounds using their laptop so the senior care practitioners can prescribe the best wound management strategy. Modern technology , eh? Can't help wondering if the pics will show up on the internet one day...!

That hand held stick welder I purchased from AliExpress arrived on Tuesday. Was itching to give it a go but my back went out later that day when I was bathing Jen and I've hardly been able to move these last couple of days. Give it a day or two more and the spasm will go just as mysteriously as it came.

You discovered the simple way to start these two strokes quickly and efficiently without engine case mods, plus the nice acceleration from dead stop without pedaling or clutch slip. The electric allows one to run a smaller trear sprocket as well for higher cruise speed without excessive engine rpm. Hybrid 2 stroke setups really work well.

Great to hear the wife is improving, but sorry for her glitch in treatment.
Tom many of us are in the advanced age category but still quite active in our lives, including hobbys. That said I don't feel any pressure to either start or finish much on my rides and for me that's a positive, but not productive. Work everyday on what I want to and recently that hasn't included much past minor maintenance on my bikes. Yes there are a few projects advancing nicely and posting on this forum section, but visible activity is pretty slim.

Best wishes and blessings to you all.

Take care of the caregiver Pete. I was a caregiver for seven years and prayed constantly that my back would hold up under the everyday lifting involved. It did!

God bless those nurses which provide care in home. They are a blessing!

I read of the storm and was struck by the intensity reported. I hope all returns to normal, whatever that is, soon.

Ride and build when you can. You've a nice project underway.

Hi, Pete,
Sorry to hear about Jen's foot. When I was being treated for the bone infection I had to go to the hospital at 8am and again at 8pm to receive the antibiotic intravenously because it was too strong to be given all at once. There were a group of regulars there and the discussion about infections and the where and how they were doing was interesting.

I have a good idea what you and Jen is going through. Hopefully they will be able to stop it's progress.

I follow a chap's blog on YouTube { HubNut} who is in Wales. He was showing the damage the storm did to one of his cars. It is a CV2 with fibreglass rear fenders and the wind which was around 90 miles an hour tore one of the fenders off the car.

Hope your back heals up. Have spate of that myself but it is a family curse that goes back a couple of generations and affects the newest generation as well.

When I was looking around AliExpress I saw the hand held welders advertised. It will be interesting to hear how it works when you get a chance to use it.

Steve.

What's happening on my end of the universe? Not hoping for rain because it's drying out that's for sure. Three storms came up the coast each one worse than the one before it. Total rain fall in British Columbia was 21.25 inches or 540mm.

We were fortunate that other than being soaked we escaped damage in our area. The worst of it started about an hours drive East of us. Devastating because that is the area where most of our local food production is. Huge losses in live stock and poultry. The farmers haven't had a chance to see how their fields survived yet but the water is receding.

In the early 1920's it was decided to drain a shallow lake that was formed by a river that passed a low lying area. They built a dike to block it off and pumped it out and farmed the land. For many years engineers have said the dike wasn't good enough and for as many years successive governments ignored the recommendations. After all nothing had happened so far and the money went to flashy, vote getting projects.

The roads were built along the sides of and over rivers because it was easier than going through the mountains and rough terrain. Where they had to go though the mountains no accounting was taken for mud slides.

To top off the nightmare there is a pipe line running from the oil fields and refineries in the next province over to the Port of Vancouver where it is stored. That is now hanging in midair in many places so no oil is being sent to the U.S. where it can be processed into fuel and sent to us in B.C. Gasoline also comes from the refineries in Alberta as is oil for shipment overseas so we're being hit from both suppliers. Gas rationing allows 31 litres or 8 U.S. gallons. You can however go from gas station to gas station to get the 31 Litres at each station.

They are bringing fuel barges up from California to supply our needs.

Now we have temperatures in the low thirties and snow forecast. Paradise Lost?

Art Ritis and I are still locked in combat so some but not a lot is getting done on the bikes. Cold and wet are giving him the edge. If it gets any worse I'll have to get a Velcro mitt and a Velcro beer can holder because it hurts to hold them because of the cold.

Purchased another lot of battery cells from AliExpress to build a 6p14s 52V battery. That is 6 cells across and each row is 14 cells long or 84 cells total. It will be used on both the electric tri car and the Monark & sidecar. Had some cells for a smaller battery then decided to just build a large one. Black Friday pricing score on AliExpress. Using 18650 cells that Tesla used.
When they get here along with the battery call holders from Vruzend I'll build it. Head lights for the Indian tri car are working their way here. I'll try and make it a busy January 2022.

All the best to everyone.

Steve.
