thcassidy: unresolved problem... the system i received is totally seized... unable to
turn the engine sprocket freely or at all. and loosing the clutch cover
does nothing to resolve the matter...
Christian Woodruff: i haven't started the motor yet but i noticed that assembling the throttle
to the carburetor the cable was extremely tight. it doesn't seem to fit
right... is this normal? also i did the test for the spark plug but never
saw fire, how do i know its not the spark plug but the wire box?? HELP!!
Richard Rowlands: I am completely unable to unscrew the philips screw that locks the flower
nut. I've tried a couple days now trying to unscrew it and now its
stripped. Any advice?
Blake Mager: My clutch is very tight and hard to engage and can't be engaged by the
wire, is this going to fix my problem?
albert costello: if you`re confused about fuel to oil ratio, you can do what I did , go to
you`re local Honda shop and buy a measuring cup for 2 cycle engine oil ,
you can buy oil there too .
freshi went scf: my clucth wont engage it is very loose every time i move the bike the
pitins move very easyley so it wont turn over properly any advice
vDaco: this is a bit off topic but, does clutch starting the engine harm it?
Joseph Johnson: hello just want to say thanks for the uploaded information..
i have a question i noticed that your clutch has a spring underneath the
clutch plate,do you need that spring for your clutch to work
properly?please do get back to me a.s.a.p. thank you.
Justin Carson: No one has made a video on a complete rebuild of a Grubee clutch yet.
There is an issue with the clutch on these engines. The adjust nut(not
the fine adjust nut) on the clutch shaft screws tighter and tighter against
the clutch spring until it completely compresses the spring rendering the
entire clutch(and engine) useless. Very poor design. 2 of the 3 engines I
own have done this. Again, I'm talking about the part of the clutch inside
the engine, not the fine adjust nut under the clutch cover. I have to
figure out a way to stop the adjust nut from tightening itself on the
threaded clutch shaft.
KingCobraJFS: The wire for the throttle cable is stripping away trying to assemble it its
the wire that you put the springs on that turns the thing on top of wear
the chain sits its to turn twords the engine but the silver wiring that you
screw down is coming on ravled and the springs are being difficult to put
fatyfisherc: I just finished assembling my bike but when i tried to pedal it, it was
very difficult like the clutch was engaged even when I held the clutch
lever. So then I adjusted the clutch like in the video and now it spins
freely all the time and won't engage.
any suggestions +BikeBerrycom ?
conker balderas: Hi could you tell me how to tighten the clutch because i can pedal freely
while clutch is on or off
Joe Franco: Tnks man! Right to the point.
Cadet Hassan: I just got my bicycle engine kit to run and I was running it at full speed
for about 2 min. When I was doing a tight turn I slowed down and the
engine turned off. I held the clutch to turn it back on but in the process
it became to stiff to turn. The engine was hot and I was holding the clutch
but it still would not spin. Would this fix my problem?
RockLobster2402: yeah got everything installed- and first time trying to start the bike the
chain breaks at the master link, so I bought a new Master link and
reinstalled the chain. When I tried to tried and engage the engine to start
the bike it just completely locked up.
Called bikeberry the guy was real nice he said to look at this video
my question is the engine is installed already and chain is on so do I have
to uninstall the chain to do this? I guess thats a really stupid question
since I just said it is locked up how would I get the chain out?
Miguel Hernandez: This was exactly what I needed! Thanks!!
Joe Franco: Tnks man! Right to the point.
J Danny Casillas: if I am replacing my square like clutch pads with new ones, which direction
do the new clutch pads go in? One side of my pads look checkered and the
other side is black......and what if the holes seem alittle too small for
the actual pads to fit in.? Is this common? and what do you suggest to make
the pads small enough to fit?
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?
Pollo Loko: How do you take off the sprocket from the clutch? The videos on YouTube

Pollo Loko: How do you take off the gear *****
William Stark: My clutch is stuck stuck stuck. Those three prongs won't spin no matter how

Ryan Marshall: Should you do this when u first buy the motor ?
Lang palmer: my clutch gear is rubbing on the bottom of the motor case WTF do i do?? i

Dominic Suniga: Ok i just set mine up and when i try to pedal that engine tries to turn

Pollo Loko: I have a 66 cc skyhawk and When I hold the clutch in, my bike doesn't move
how can I fix it?
pavel1809: let says if my motor is off and i ride my bike for 4 miles my cluch will
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!
