General Discussion / Re: Why is my 50cc holding back accelerating? Please shed some light!

Added to the air box, the plug was soaked and fuel was backing into the air box. The plug is about the right colour now, slightly black, but not as bad as when I got it, the element is a dark brown colour.

General Discussion / Why is my 50cc holding back accelerating? Please shed some light!

Hello, I’ve had my kymco super 9 for a little while now, and having ongoing issues with power, I know these things don’t exactly make massive power, but it’s just not as responsive as I’m used to with previous 50cc scooters I’ve owned, ive got 0-15mph takeoff running good, but 15-35mph is so slow. Really hoping someone can shed some light. So far I’ve fitted a de restricted cdi, upjetted to a 90 main jet, fitted a new variator (de restricted) 7g rollers, new clutch, new belt, iridium NHL’s spark plug, and it came fitted with an expansion chamber exhaust. I just want it to exellerate smoothly and quickly, and possibly get 40/45mph to keep up with traffic. Idle is fine, and the fuel/air Screw is turned out about 3-4 turns, I’ve also added 3 small air holes as it was running a bit too rich. Thanks :)

I'm looking to know which Screw adjusts idle, and which for fuel/air, I've attached a pic of the same carb. Thanks

General Discussion / Super 9 wont start with new cdi?
« on: September 10, 2017, 04:04:23 PM »
Ongoing with my super 9, I have it running ok at the moment, but I want rid of the cdi restriction, so it revs a bit more freely. I have the ac with 6 pin, I bought the gy6 unrestricted cdi as mentioned on here, but upon fitting, the bike just wouldn't start, re fitted the old one and it strikes up first time? Any ideas on how to fix this, or am I stuck with a restricted cdi? Thanks

Super 9 / Re: Problems accelerating
« on: September 07, 2017, 08:14:14 PM »
No it doesn't have tach, I was doing some tinkering today, and I have a feeling someone's increased the main jet, maybe running a pod filter, there was the intake hose missing, so I bought some flexi ducting and replaced it, and had no acceleration at all!! I need to get some gaskets / sealant before I can strip the carb down, and likewise I need to get a spark plug Wrench to see if the plugs black, but for now I've removed the air inlet again, and added some holes to my air box, and I'm seeing an improvement, but not perfect yet, just don't want to go to far and run it lean. What else can be done to the cvt?

Super 9 / Problems accelerating
« on: September 06, 2017, 06:55:53 PM »
Hi, looking for some advice, just bought a 50cc super 9, and it really struggles to accelerate. Just want to know if anyone's got any advice on how to solve this? I don't know much about the history of the bike unfortunately, but as far as I know it's standard, but does have an expansion chamber exhaust.
So far I've put a new clutch, variator rollers (7g) belt, cleaned up the variator face. So I'm pretty sure it isn't drive related. I have just taken off the air filter to clean, and it did have a small (maybe 1 tablespoon) of fuel in there? It runs great otherwise, and does about 50mph, it's just initial takeoff is painful, sometimes I have to assist it by scooting it with my foot! Thanks in advance:)
