Roketa Bali 150cc Problems By nk757 (Read 1,828 times)

Okay, so i bought a used 150cc Roketa Bali off Craigslist yesterday for $400 bucks. Body is in pretty good condition, needs to get a new speedometer cluster and some electrical work. I knew there would be some issues with it. When i got there, it took about 10 minutes to start up, so i figured it was the valves. I purhased it and couldn't get it started when i got home. After adjusting the valves, it started right up and so problem 1 fixed ( i assume ) ... Now i still don't have much "oomph" or get up, i don't have a working speedometer, so i had a friend follow me, and i got to 40 mph, after about 2-3 miles.... I don't know what else i could look at that could affect my top end.

It is a GY6 Engine

Any and all suggestions are welcome . I'm new to the scooter world!

150cc SHOULD get up to about 55-60, depending on how heavy you are(180-220lbs) SHOULD be fine. ARE YOU SURE, its not a 50CC Roketa Bali??? IF IT IS, thats about all your gonna get out of it.

IF ITS A 150cc, what are your valves set to??
Have you done the regular stuff(Carb Clean, Fuel Tank Flush, Fuel Lines, Air Leak Check(Exhaust&Intake, Spray some starter fluid around ALL seal, intake manifold, exhaust manifold, hose to air box) What settings do you have your carb at? The Needle setting mainly.

Let us know all that ^ Information, and we can go further! I am thinking you MIGHT have got a 50cc...

Look on your engine under the variator case on the left side and you should see a number stamped. its probably either QMB139, 139QMB, or something like 157QMJ. that should tell your engine displacement (cc)

It should be a 157QMJ, check your CVT especially the weights in the Variator and check the belt.

Bali's are heavy 50 miles per hour is about the best you will get . How many miles pn the scooter ? Check the belt for wear .

Mine weighs 298 LBS with out my skinny azz on it

i weigh 160lbs, the bike has 2500 miles on it... it is definitely a 150cc as i have the certificate of origin. I don't know what my carb settings are.... I just adjusted the valves, i didn't have .0019 , so i used .002 on intake and exhaust. I wasn't too sure if adjusting the air/fuel screw would do anything.... it's definitely lost at least 1/4 it's power.... I'm probably just going to take it to the scooter repair man, but i'm trying to see if i can do something myself to tide me over...

and yes, 157QMJ

I was looking on EBAY at some scooter parts, i was thinking about getting a big bore kit and having the guy put it on, that way i can have SOME newer parts on the scooter... I'd like it to run it's best, but also have some "oomph" to it

Holy crap!! I thought my JMStar was heavy @ 250 dry on a scale

[tvnacman]

I set my valves to .004 . If you lost that much power I would redo the valves and compression test it .

.004/.004 is perfect valve adj. .002 is a little tite
