how do you start/ stop the engine on a rack mount system?

I am thinking of getting a Staton gear drive and I would like to know the starting and stopping procedures. I know they have a freewheel on the pedal side but does the drive side chain and gear always turn? If so, and the clutch is centrificul how do you bump start the motor by pedaling?
Thanks
 
There are two ways to stop the engine: a kill switch OR reaching behind, flipping the choke ON, and touching the throttle to flood it.

Starting by jumping the clutch? Don't know how that would happen, since there is no ON ignition position, just a rope start.......

I could be wrong, but don't know how.....
 
Only a pull start, no other way to start it since it is a centrifigal cluth....but..the Golden Eagle Bike engine system is superior to their gear system in all aspects. Check out this site:

why do you say it is better? I worry about the belt breaking or just wearing out. The gear setup looks like it would last forever. Thanks for the input guys.
 
The belt is made out of Kevlar and manufactured by Gates (the world's most trusted name if belts, hoses and hydraulics). I bought a backup which only cost around 25.00. Golden Eagle has told me there are many people with 5-7000 miles with no apparent problems. I have around 1200 miles on my original belt since I purchased the Golden Eagle Bike Engine drive system 7 weeks ago. The belt is basically flawless. The problem with the Staton system is this: It is heavy and large, a reduction gear package that loses energy. It is maybe only 60-70 percent efficient in energy transfer, in other words, lots of energy is lost from the engine shaft to the wheel hub. The Golden Eagle system is around 92 percent efficient as it is a direct, belt drive. Belt drives are much more efficient than chains, no oil residue, etc. That's why you see so many belt drives on different motorcycle manufactures' models. Before the Golden Eagle, I had Staton friction drive for 2900 miles. It was junky. I have talked to people that have experience with the gear drive from Staton and the Golden Eagle, there is no comparison regarding reliability, performance and weight. My Golden Eagle is superior to the Staton I had hands down. Whatever decision you make, enjoy and be safe.
 
Everything runs on belt these days, and there are 3 ways (2 on installation and one on performance) to make the belt last for thousands of miles. .

1. The spoke ring being centered, reducing tension arm "loopiness".

2. Dry fitting the rack/gear/belt. Before you ever put the engine on, you make sure the belt is running pretty close to center in the middle of the gear. 8 times out of 10 it is pretty well "in the groove" on the first try, but if you see it is touching the edge of the gear, you put spacers down at the axle, and get the thing lined up.

3. Start with the "normal gear", get the hang of it before moving up to the "highway gear".

You start getting used to the noise of the engine, and it will tell you "help out on this hill with some pedaling, or let of that throttle some".

It soon becomes second nature, especially on familiar turf, where you know how to get the jump on various hills and inclines.

I carry an extra belt/inner tube and drive shaft on long journeys, so if it did break, it is a 5 minute roadside repair. Dennis at GEBE added more kevlar and deeper grooves around January of 2006, and the performance has increased substantially.
 
Motorcycle belt drives

Okay so I'm nitpicking here but..... I wouldn't say that 'most motorcycles' use belt drive, it's actually the other way around. In the case of a simple bicycle chain, it's more like chains are 98% efficient versus 94% efficiency for the same set up using a belt. (Yes, there are a few belt drive bicycles, not many...Mercedes made one) As for motorcycles, they're in a different league. Belts can't handle the torque/horsepower that chains can, AND belts are more susceptible to damage from rocks and debris found on the road. (If you've ever been to a motorcycle drag race, don't be surprised to see some of them snapping belts on drag bikes that use them) Also, it's far easier to change gear ratios on a motorcycle with sprockets as compared to pulleys and a belt. Personally, I liked the idea of a motorcycle with a belt (no lube), but only Hardley's/Buell's and a few crusier type Japanese bikes had them. After getting about 27k out of my mc's chain, I was satisfied.
 
:cool:Torques, you have your opinion.

I wonder why many GEBE owners worry about breaking spokes and motor strap. and how ya gotta take it easy, so as not to abuse the setup, as GEBE would berate some of their customers. maybe that's why engines over 2 hp aren't offered or condoned on GEBE installs.

i have STATON gear chain drive, and i'm glad i do.i like unbreakable stuff. i'm on full power as soon as i push off from a standing start. no need to worry about breaking spokes or motor mounts. i carry my bike up and down 2 flights of stairs whenever i ride, so weight's not a problem for me.

about power loss thru friction? when you're flying over 30mph on a 20" bike on 2.2hp, am i experiencing considerable hp loss?(with .7962 handicap factor, that's about 41 mph on a 26" bike.)

i don't think so. if i am, that's plenty fast enough for me.

if ya want to baby your motored bike and limit yourself on how powerful of an engine you can use, choose GEBE. if you want to apply power gradually and enjoy the scenery, choose GEBE.if you wanna run 15hp, not 1.5hp, choose STATON. if you want to apply full power and not worry about breaking belts and spokes, choose STATON.

by the way, i use 14g spokes, and haven't broken anything yet.(except the master link.) when i upgrade to more hp, i'll install larger spokes.

my next project is to install a more powerful 49cc pocket bike engine onto STATON drive. it literally bolts onto the drivetrain. after that is an aircooled 40cc POLINI bike engine. finally, the watercooled 15 hp 50CC POLINI engine
the POLINI engines have 80mm clutches and a radiator:eek:, and may need slight mods to the STATON gearbox to bolt on.

and of course, STATON gearboxes have a lifetime guarantee.

in the end, it's an individual choice, and it doesn't bother me what people ride.

I, too think the Staton chain drive is the toughest thing out there. When you turn it off with the switch, the gearbox and drive chain stop almost immediately, the only thing going is the little "tic-tic-tic" from the drive freewheel. Also, I can reach behind while pedaling and pull the rope once (twice if I haven't run it for more than two days) and it always starts. I haven't used the choke even once in the 500+ miles I've put on it so far! It has more than enough power to keep me at or above the 20 MPH speed limit here, I've climbed some serious grades, and done some off-road riding on dirt and very loose gravel.
 
...does the drive side chain and gear always turn? If so, and the clutch is centrifigul how do you bump start the motor by pedaling?
Thanks
The drive side of most systems does always spin.

If there's a centrifugal clutch, then you need a rope-starter on the engine or some way to spin it. The centrifugal clutch has a bit of drag but not nearly enough to start the engine.

The belt-drive probably has less vibration than the chain setups do, but the chain setups can withstand more power. The gear reductions that some setups like Statons use makes me wonder about durability.

{just dreaming}
Ideally I'd like to use a chain-drive setup, but a direct drive with a centrifugal clutch (and no gearbox involved)--sort of like a GEBE, but with a chain instead of a belt. If I ever make my second attempt with the Lifan engine, that's what I think I'll have to do.
