Samuel Poe: I just purchased an 80cc engine and installed on to my bike. Everything is
working except the clutch. I can get the motor running but when i try to
stop at a stop sign or just stop, i pull in the clutch lever and the engine
noise increases dramatically. I have no choice but to push the kill switch.
I can't keep the motor running. Sounds like it will explode if i did. I
know it is not suppose to do that. It's suppose to keep the motor running
at a lower noise, then when you resume riding, you let the clutch lever
out. Do you need to peddle again to keep the motor running after resuming
the ride after leaving a stop sign? or is the 80cc motor capable of
resuming the ride after a stop at a stop sign without needing to peddle?
jmld69: Thanks that was really helpfull I was looking everywear for videos on how
to dismantle clutch and u answered my question
R. Beyer: thank you much
Jose Cortese: the clutch handle is stickey
Lang palmer: my clutch gear is rubbing on the bottom of the motor case WTF do i do?? i
tried this out of spite but no luck obviously is the gear grinding along
the bottom Plz help?!
Jason Teasdale: Hi Bike Berry, I find your vids very helpful. I have built 5 of these
Grubee Skyhawk kits now, and sell them. The last 48 cc I did has a rattling
noise in the clutch area. Now I have heard this is "normal" sometimes the
pressure plate is out of round or something like that? I haven't opened it
up yet, but do you have any suggestions on what that rattling might be? the
nut loose maby? The engine and clutch work except the clutch will not
engage until the clutch lever is almost ALL the way out. On my 66cc it is
not like that. I will try and adjust it this weekend and see if anything is
loose in there, but your opinion would be greatly appretiated!
William Stark: My clutch is stuck stuck stuck. Those three prongs won't spin no matter how
long I bang on them. I'm afraid I'm going to break them.
pavel1809: let says if my motor is off and i ride my bike for 4 miles my cluch will
Dominic Suniga: Ok i just set mine up and when i try to pedal that engine tries to turn
over and wont let me pedal will doing this help
Mexside619: just adjust the screw on the side to let less air in
bikr1975: ohh yeah, i replaced the plug with a small engine type for honda. is there
any difference in resistive to non-resistive plugs as far as power goes?
the original dies and replaced it with a similar sized one. when i first
got it, it was like it was turbocharged. had lots of low end power. now,
all of a sudden, it bogs right down with no low end power and feels like it
wants to lock up if i try to get more speed. im using a 40:1 full synthetic
racing oil. no plug fouling. bad CDI????? help.
BikeBerrycom: It's locking up because the fuel ratio is incorrect. These engines require
a much richer fuel mix. I say flush your motor, and refuel it with a 24:1
ratio. If it's still in the break-in period, 16:1 or 18:1 should be the
wav5000kb: Weird background noises,turn up the volume an listen.
chappytk: You should make more videos. Concise and well edited. Thanks!
RockLobster2402: I bought a small Bike engine exactly like this- except it does not say
Skyhawk, I did everything you say to do, and I found the Spring in the
video at 1:39 (time) is missing. ----- where can I buy that Spring?Are they
universal? The Name on my box the bike came in says BGF "Boy Go Fast" if
that is any help. I got this back over the Summer and with the Hurricane
and other things,Am just now able to put it on--- Thanks.
BikeBerrycom: That's the first time I've heard of that problem. If it doesn't effect your
flower nut negatively, you may want to file down the clutch pin. Please do
so at your own discretion though, as we are not reliable for this advice.
PLEASE NOTE: do so ONLY if it doesn't affect the flower nut negatively, as
in, it causes the flower nut to sit and screw back on the clutch pin
rodney dikin: i've got the grubee skyhawk 66cc and i absolutely love it. i customized a
cannondale h300 and installed this motor kit. i used some of the parts that
came in the kit but did away with most of it and upgraded better parts. the
engine is fantastic. get rid of the sparkplug that comes with it. it's
crap. get a ngk or autolite. and your best friend is going to be loctite.
use it to the max. it will save you from loosing parts and keep your motor
secure. email me at firstname.lastname@example.org for more tips
hamslam199: man im glad i finnaly found out how to fix this thanks man
tibetoo7: hello.can u use this in a kart ?
BikeBerrycom: In all fairness, it's true that the 2-stroke engine kits or "china girls"
need fine tuning. I can't speak for most other stores, but we offer a 6
month parts exchange warranty. We understand how these engines work and
will work with you in making sure you get your parts to get your engine
paraglidermx: All china girl motors are POS,,if you dont know how to work on 2
strokes,,dont buy one from anybody,,I have no problem buying them fro ebay
for 139 dollars,,just need to go over them and fine tune,,they all run
great with some TLC :)
BikeBerrycom: Power loss is generally due to the carburetor not being adjusted properly.
When you twist for more power, the carburetor is trying to feed more fuel
and air through a small jet.
BikeBerrycom: No problem, Alex. Glad it helped :)
sagy cohen: Why when i stop the bike the engine is just shut down?
ThePeoplepimp: This is trouble shooting not adjustment, but cool video...
shredderjoachim: Hey man here is my problem. I have tried putting the cover that goes on to
the sprocket on the side of the clutch that you were showing in the very
beginning of the video but the pin is blocking me from putting the cover
back on. I have tried taking the clutch cover off and the plate as well and
fiddling with some of the settings. I cant get the stupid cover back on
that you took off because the pin is seated way to far out of the housing.
I have checked for dirt and grime.. help please!!
mitzy162: Thanks for the help! My three prong thing was frozen :)
Matthew Schurter: Nice vid Guys I have also had two engines recently a 48cc GT2B and 66ccGT5
where the plate was just stuck to the clutch pads and used a small slotted
screw driver to unstick it by gently prying around the radius of the plate .
Jose Jimenez: What if clutch is not un ingadgin
Sam McDowell: THANKYOU
Daniel Smith: the clutch arm is at normal position and the clutch still moves and or not
engaging with back wheel???
BikeBerrycom: Great advice! Thanks for sharing.
mhamo9922: im Egyptian i want buy the engine
iryan74656: Umm I thing from now on I'll shop here for my engine need and upgrade parts
I spend way tooo much on motovelo.us crap bad service there
TenSixtyFive: im having the opposite problem! it will disengage but not fully engage (the
back wheel still spins somewhat freely when its in the engaged position).
Samuel Robinson: flywheel not clutch cover
Jose Gutierrez: You re the best!! Thanks!!!!!!!
DONphantasmo: Great video!! Thanks
bikr1975: sorry, i guess my main question is, is there a common cause?? the head that
came with the replacement engine, the underside of the head has a recess
for the spark plug. the old one is a slant head type with no recess. ok,
carb, plug, CDI or the worn out bearing?? ill replace all if neccesary.
mindcrime420: I cant get my clutch to engage the back tire spins free wether i squeeze
the cultch in or not tho i can see the plate move yet no matter how tight i
tighten it the back.tire spins free
Jamie Remington: I've done that and Engine has will not engage....
Darkman S Bhuller: Thank you so much, GOB BLESS you. I found solution to my problem
charlenecarter60: How do you fix a carburetor that idles high
Cody Randall: this is a great engine but now i know whats wrong with my clutch thanks :)
Paul Solver: FYI I'm 99% sure this is my problem. I have the 80cc/66cc Flying Horse.
Just so you can pass along this problem to others
ethanarpit: Hello, I am thinking to get 48cc skyhawk. is the engine quality good? i
don't know much about engine so I dnt want trouble to end up fixing it in
future. n is it too noisy n will i b able to go uphill easily?
guitarnerd19: The three pegs on my motor refuse to turn, they will only go about 1/2" in
either direction. I know you said to assist it with a hammer, this did not
seem to help move it. Have you ever heard of this problem before/have any
Luca Infante: My 50cc moped has resently packed up on me and i can't push it freely it
feels like its in gear or at least stuck in gear but i'm not sure whether
is somthnig to do with the chamber and piston/rollers or whether is just
the clutch is stuck in engaged - Please Help! :)
Brad Cook: hi there, did you get your fixed. Im having the same problem. Went into
gear initially, now it wont go into gear at all. Stays in neutral. Did you
figure out what it was. Thanks
Alex Chan: I had this problem with an 66cc engine I got from Zoombicycles. Thanks for
