The Grubee Starfire 66 cc GT4 is made in the Nantong JiaLi Gas engine factoryThere both made at the Yuan Dong Factory.
Nah , there is a huge differenceSo yeah, pretty much the same....
I don't need to post a pic of the label side of a starfire gt-4 as I have a whole stack of them here and I know exactly what the tag says.BTW my starfire gt-2 was made from the Yuan Dong factory and thats why i thought the new starfire gt-4 would come from the same place but it doesnt help if the sites that sells them doesnt tell you s##t about where they come from.
i ask anyone thats thinks diffrent to post a link of a picture of the label side of a starfire gt-4 engine that states where it comes from.
The pictured Grubee 50 cc GEN II is made in the same Nantong JiaLi Gas engine factorySTARFIRE - GT4
Engine: 66cc- 2.85 hp
Nantong JiaLi Gas Engine Factory
It says it was manufactured on 7 2009. is that one of the bad ones? and yes it was a48 verry slow I baught the limited edition black one It def is a runnerNo actually there is a big difference first is the match as far as the transfer ports then there is the Quality of the lower end Bearing (23 Needle verses 16 needle in a poorly Engineered cast)
The Nantong Jiali Manufacturer is known as the better if not the best engine manufacturer exporting these and have lost contracts with people Because they refuse to Mass produce cheap engines.
If you've replaced A starfire with a Jet your Stafire was probably a 48cc'er thats about the only ones left. Also the Starfire is the factory that your Jet was Manued at..And if it is is out of one of the First two shipments of Jet Engine they have lower end problems due to the fact a Customer I wont say no names but is actually thier competitor convinced them to use a Poorly casted Lower end Needle casing. They all need replaced. As a matter of fact the ones that are correct and Have 23 needles are still on thier way too them. I never received the 16K Needle bearing with the problem because I have the prints too it and refused to Allow them every order to put them on the bottom of my Connecting rod.
I deal with this factory and its Management Exporter and are very good friends talking at least once a week.
the gen 2 steel sleeve starfire?? with 8 mm studs? or the jet? confused lol thanksActually no you got the 23 needles your good to go. I am online with my Plant manager as we speak and the latest shipment which was July were the needles instead of the GR..I mean bad casted needle bearing case!
As far as your 48 cc Starfire goes Milling the Square part almost all the way (I went all the way) off the head is a compression boost it needs. Also using silicone on your intake to carb slide junction is the best performance tips I can give you.
I have that engine you have there but with the 8mm studs I finally got them to change to the bigger head studs, And Better paint for the exhaust, A little more ballanced crank, Lower Intake casting, and Higher exhaust port casting. You got a real performer though. Got to go Sir. Peace.
You should have bought it from Bicycle-Engines.com. Here is the site 50cc StarFire Gen II Phantom Edition Engine - $149.99.That was the motor i was supposed to get from GASBIKE.
They sent me a GT-2B all black and then only gave me $10.00 stor credit.
What a CROCK.
Wish i woulda got that engine instead of the mistake they made.
