Agility 50 / Re: Won't rev unless the brakes applied
« on: October 20, 2014, 09:10:57 PM »
Over the weekend I removed some of the plastic and traced the ground cables from the -ve battery terminal to the frame and the engine.  I check the continuity of both wires and the continuity from the battery to the engine and from the battery to the frame.  All were fine.

Connecting the battery to the engine or  frame using jump cables did not solve the problem.  I checked the continuity of my cables and they were also fine.

Before I give up and duct tape of the headlight switch (keeping it in passing mode) is there another ground wire, fuse I should check?   

Thanks

Looks like BettinANDlosing was right it's a ground problem.  Basically if I turn the blinkers on or the have the front light on 'passing' it revs.  With the blinkers on it revs in tune with when the light is on.

Now I just have to figure out how to fit it.

I have no answer, but a bit more information might help with a solution.
What does happen when you try to rev the engine without the brakes being applied  ?

Engine RPMs stay the same ?
Engine dies ?
*******************************************************

When I rev the engine without the brakes applied there is no increase in revs.  There is a slight change in engine noise but it is minor. 

When I reved the engine with the brakes applied for several minutes yesterday the engine eventually died.  I was subsequently unable to re-start.  I went back out after a few minutes (perhaps 5) and it stared fine.

As soon as it stops raining I check the main ground as suggested by B&L.

Thanks to all

Agility 50 / Won't rev unless the brakes applied
« on: October 10, 2014, 09:43:30 PM »
Can anyone explain to me the mechanism behind not being able to start without the brake lever being applied?

I have no problem staring my Agility.  The problem is that it won't rev unless I have one or other of the break levers squeezed. 

I'm trying to figure out what is going on and how to fix it.

I can't ride (or get my scooter to the mechanic) as it won't rev without the brake applied, with the brakes applied it won't move.

Thanks

Agility 50 / starts fine, no power
« on: August 05, 2014, 07:56:27 PM »
After sitting idle for the winter I started my 07 Agility and it initially ran fine (~1mile to get fresh gas).

Later in the day I took it to the bank, at a couple of stop signs I gave it gas but nothing happened, no power. After a few seconds and multiple twists of the throttle power returned and I was able to pull off.  At no time did the engine stall.

The next time I tried go for a run the scooter started fine but no power.  When I twist the throttle there is little if any change in engine speed although there is a change in engine noise.

Any idea of what my problem might be and how much it would cost to fix?

Don't think that it is related but the battery is flat, lights etc work as expected when the engine is running.

Thanks

Agility 50 / Re: problem with fuel gauge
« on: April 06, 2010, 06:07:12 PM »
I have the same problem with my fuel gauge not working.  Over the weekend I took the consul out and check the connections and then removed the sensor from the tank.

I fiddled with the sensor and got it working. Put it back in the tank and it still worked.  Put it all back together in a hurry (but didn't check it when finished as my wife was waiting), turned it on yesterday and the gauge isn't working!

I like the idea of prodding the sensor with a rod through the gas port.  The sensor consists of a float a couple of inches long that moves up and down based on the level of gas.  To get to it you need to remove both seats, the rack, all of the trim from the seat back. 

Not sure if my problem is with the sensor or a connection.  If I can get the needle to move prodding the sensor it is presumably a sensor problem (~$25) if not is is likely to be a connection.

Agility 50 / Re: Too Long to Warm Up
« on: February 05, 2009, 02:34:46 PM »
I have exactly the same problem.  Takes the bike 10-15 minutes to warm up.  If I try to ride it before it is fully warmed up it will not respond when power a re-applied.  Usually happens as I'm pulling into a junction, scary!  Took it to the dealer in Northern Virginia and they charged me $150 and told me to let it warm up fully.  Got a cock and bull story about there being a wax part that needed to melt before driving the scooter.  I left in disgust.  I suspect that they never tried the scooter outside their climate controlled work shop. 

I've got some online advice .  I've been told to check the auto bystarter (which as best I can tell functions as a choke).  Down load the service manual (it's available online as a pdf) and look at section 5


The advice I got was to check the plunger for corrosion. 

Remove the  auto bystarter and apply 12 volts to the terminals and see how long it takes for the plunger to move out.  The auto bystarter should get warm very fast.     I'm going to try doing this this weekend and report back to my 'advisor'.  I'm not sure how long it should take for the plunger to move etc.  I'll post back what happens.  The service manual appears to have a similar test (see below)

Hope this might help someone as I know you pain and frustration.  If anyone out knows if this make sense or knows of a solution I'd love to hear about it.  Seems like this might be a common problem with the Agility.





The service manual has the following

AUTO BYSTARTER
OPERATION INSPECTION
Measure the resistance between the auto
bystarter wire terminals.
Resistance: 10? max. (10 minutes
minimum after stopping the engine)
If the reading is not within the limit, replace
the auto bystarter with a new one.


Connect a hose to the fuel enriching circuit of
the carburetor. Connect the auto bystarter
yellow wire to the positive (+) terminal of a
battery and green wire to the negative (-)
terminal. Wait 5 minutes and blow the hose
with mouth or vacuum pump. If the passage
is blocked, the auto bystarter is normal.
Disconnect the auto bystarter from the
battery. Wait 30 minutes and blow the hose
with mouth or vacuum pump. If air can be
blown into the hose, the auto bystarter is
normal.

REMOVAL
Remove the set plate screws and set plate.
Remove the auto bystarter from the
carburetor.

AUTO BYSTARTER INSPECTION
Check the auto bystarter valve and needle
for nicks, wear or damage.
If any faulty part is found, replace the auto
bystarter as a set.

INSTALLATION
Insert the auto bystarter into the carburetor
body until it bottoms.
Position the set plate into the groove in the
auto bystarter and tighten the screws.
