grubee skyhawk 80cc

[geoffmaree]

can anyone give me an honest opinion on the grubee skyhawk 80cc (66cc) motors.

[skinnydog1_2007]

Yes I’m interested too china girl engines are the pits so unreliable. Had the bike motor for less than three months. Clutch cable snapped, accelerator pin to handle bar hole snapped off, chain tensioned fell apart, rear engine mount bolts snapped off in the block, magneto and cdi crapped out not once but twice replaced, main drive gear got stripped had no teeth left on it there is more but I’m getting depressed writing this thinking about the long long rides back home using the pedals because the motor died along the way, Anyway I’m interested in the grubee skyhawk 80cc (66cc) motors as well. Are these made in china? Alot of other China products seemed to be out for a fast buck to their own shame building poor quality items. If ever china goes to war like a world war 3 type thing they will surely be defeated if they build tanks and planes like my bike engine.

All of these little two strokes are made in China. I have bought six from six different vendors, some run better than others. I have one of the Grubee Skyhawks. It's o.k. Wouldn't say it is much different than the rest of them. I haven't had any major problems with any of them. They do vibrate more than I would like. Especially at high r.p.m.'s
There is a solution to this. If you want a vibration free motor in a two stroke you are going to have to pay the big bucks. Get yourself an Italian made 49 c.c. Morini Franco for around $500.00.
I am going to try one on my next build.

if you go to usabikemotors.com they carry a deluxe motor of the 66 cc crubee i think they go around 200. i have a 58 cc star fire crubbe and so far no problems

i reccomend the 48cc dualstart starfire gt-2 grubee motors from gasbike.net.
my motor is still running strong with no major problems.
my gascap broke and a master link on my chain,but those are cheap fixes.

topspeed 35mph all stock,180-200mpg,and the engine still starts the first time.

Yeah, but they will have 40 of them to every one of ours and can fix them with parts from an old kitchen sink.

Does anyone have any real experience with the "Skyhawk"? Not "Starfire". So far only Retmachinist is the only one to comment.

[city of angels]

skyhawk motors is related to the star fire motors i did heard that both engines are really good quality i have mine about a month and so far no problems

[Bikeguy Joe]

They are all "related" to one another....actual experiences please?

I have a skyhawk 80cc and i have not had any problems. One of my friends rode mine am bought a stinger 80cc and it is the same thing just doesnt have a dragon eating a snake or something on the side. I tore my engine all the way down when i got it to get the china out. The engine looks prity good i am very happy with it. The choke cable broke very quickly because some of the sleeves were not debured. The twist throttle broke but i replaced it with a 4 wheeler thumb throttle and it makes it much easier to pedal/ride. I would buy one again I am very happy with it.

Just dont look inside the muffler. I cut mine appart because i made a tuned pipe and it looks like a 12 year old used a mig welder with no gas(non-flux core) and some steel he found in the trash.

Hope it helps.
