Lexmoto Venom 2016 need HELP!

[Swannyuk]

I brought a labour emergency 125cc bike as my misses is pregnant and I needed a some wheels as she still needs full use of the car, I am not new to motorbikes either i have had several 125s and was about to do my module 2 test but had to on hold due to the little one on the way.

Now I brought this Lexmoto because it was cheap as they are and still had a year before it need its an MOT. I have had nothing but issues.

It wont exceed 50 mph and cuts out when you come to a stop.

I have checked and adjusted the following;

-Spark plug adjusted the space but didn't need replacing.
-battery was a little low but on charge now
- Cleaned the carb and the air filter
- cleaned the fuel filter,
- and done an oil change,

It still cuts out,

I am competently stumped on what the issue is and hoping someone on here will know.

Please help before a take a baseball bat to it.

What year, and model. Is it FI or carbed? People will need to know to give you advice.

Idle mixture is fine, I've increased the idles speed, sounds like its on the chock when I do, so I have it on 2000 to 2500 rpm,

I have discovered that the alternator is faulty. I am not getting to the charge to the battery, so i have ordered a new one,

I must say it is the most easiest bike to bump start. Its still a peace of donkey poo.

It's not an alternator, but have you checked the regulator and the stator output to determine which one is fucked.

Idle is too high, needs to be around 1400-1500 when warm.

Mixture screw all the way in and 2 turns out. Start there.
