Below are some common problems and solutions I am frequently asked about
(I'll try to post this to my website in a few weeks.)
For all of us that have bitching and and moaning about the brightness
of the Hyosung Sense/Tomos TSR50 headlight bulb brightness, as solution
is at hand. Moped Hospital has found a new bulbs which should dramatically
increase the brightness, and is a drop in replacement for the factory bulb.
This is the bulb the factory should have used! I believe they are
Halogen, but are the same what as the factory bulb. Steve at Moped
Hospital has tested them, and he says they work great.
The bulbs should be available from Moped Hospital(Steve) or Solano Cycle(me)
in a few weeks. I don't know the price yet. Let me know if
you're interested and I'll get the price for you asap.
Another weakness that has been addressed is the charging problem.
The Hyosung does not produce its maximum charge until very high RPMs, this
causes the batteries to regularly become discharged if you are just commuting
in slow moving traffic, or idling for any period of time. The Southeast
distributor, AMED, has just informed me that you can replace the stator
with a stator from a larger displacement Hyosung scooter(I believe a 100cc
model) and it will solve the problem. It generates a much better
charge at a lower RPM, and is a relatively easy drop in replacement.
You'll need to specify to your dealer to order the new stator, not the
old one. I think he said they will be using this stator in future
Hyosung Senses.
I personally have not tested this new stator. I'm taking his word on
it that it works. I'll let you know the results the first time I
get an opportunity to try it.
Exhaust Heat Shield Breaking Off
No solution to stop it from breaking initially, but we have been tack
welding the tab back on when it breaks and they don't usually break again.
The weld is stronger than the original tab. It is simple and cheap
to do. Probably $10 at your local muffler shop.
Hop in the front wheel
Replace the cheap-ass factory tire with a Sawa. The Sawa is inexpensive,
and is much better than the factory tire. It is readily available
in the US from STR Motorsports(the former Hyosung distributor) and works
well on the scooter. We charge $40 installed on the front wheel.
However, it should be a warranty item if this occurs on a new cycle.
There are better tires, but you will have to pay more. FYI: The old
distributor, STR, sells both the factory and the aftermarket tire for much
less than the new supplier, Kasea. So, you'll want to find a KYMCO/Old
Tomos TSR50 dealer if possible.
Baffle breaking loose/rattling inside the Exhaust
This is annoying as hell. Hyosung needs to use better metal on
their exhaust pipes. This problem occurs more frequently when the
governor wire has been disconnected because it puts more stress on the
exhaust.
Two solutions: You can replace the pipe with a new pipe and hope
it doesn't happen again. Or, you can replace the pipe for about $40-$50
more than the stock pipe with a Technigas pipe which is now available in
the US. You'll also gain about 5mph, but the engine does wind up
pretty high to get that 5mph. You can cruise at 45mph without having
to keep the throttle wide open. The pipe is available from A&R
Trading(they only sell to dealers). You'll need to find a dealer
that gets parts from them, or hunt it down overseas on your own.
If you can't find one locally, I can ship you one. We sell them for
$140 in the US. They come with roller weights. I've tried it
with and without the weights. I personally think the bike performs
better with the stock roller weights. This is good, because it means any
jo-schmo who has a metric socket set can easily install it without paying
ridiculous labor rates for 10 minutes of work.
We don't go by the Hyosung owners manual or cycle decal for tire pressure.
It is too low. We did so on our first batch of rental bikes and ended
up replacing a dozen tires a few months later. We've been running
our tires at the max PSI written on the sidewall of the tire and we haven't
had a problem with abnormal wear ever since. Nor have we had a tire
failure from that tire pressure. The plus side is that you also get
slightly better accelleration, top speed, and fuel economy. The down
side it that the bike will ride a little firmer(although this is really
a plus in my opinion because it is safer and more agile.)
The kick starter just sucks on these bikes, which is ironic because
you have to use it so much due to the weak charging system that drains
the battery! The kickstarter on this bikes is really just a backup.
If you use it constantly, the retaining pin will wear out and the kick
starter will eventually get pushed in and gring against the gears inside
and/or stick. If this occurs, you'll need to remove the transmission
cover, reposition the kick starter, and "replace" the retaining clip with
a new one. DO NOT reuse it. You'll be repeating this whole
procedure within a few kickstarts if you do.
Regardless of how often you use the kickstarter, you'll need to periodically
take it apart and grease it if the bike is stored out-doors. Otherwise
it will eventually stick. To do this, you'll need to disassemble
it, grease the shaft, and reassemble it. Just make sure you note the position
of the spring and reassemble it the same way. You'll know you got
it right when the little groove that holds the retaining ring is sticking
out the transmission cover. If you can't install that clip because
you can't see the groove, then you'll need to tinker with it/adjust it
until you do. Make sure the clip is seated in the groove all the
way around, or it will pop out on the first kick start.
Rear Wheel Touching the Ground/Bent Stand
Stop sitting on the bike when it on the stand, stupid! Or, lose some
weight! Seriously though, the Hyosung has a relatively weak stand
that bends easily. For a quick fix; get a large wrench or metal tube(such
as metal conduit from Home Depot) with a small diameter, put the stand
in the up position and have a buddy hold the bike, put the tube/wrench
over the end of the stand that you would normally step on and pry it up.
This won't make the stand work perfectly, but it will work better and keep
it from dragging on the ground in sharp turns. It is better to replace
the stand, however, if you can afford it. They aren't that expensive.
I hope this helps everyone out there with Hyosungs. If I can be of
anymore help, just post a reply or email me.

Does the Hyosung 50 have some sort of a governor or restrictor that slows the amount of fuel that gets to the motor?(I'll try to post this to my website in a few weeks.)
