Shineray X1 performance problems (xy-150-11a)

[prince666]

Front brakes is bent disc
Black smoke at high rpm is excess fuel unless it's high altitude only then needs rejetting
Chain stretching can be rest sprocket wear - a set with chain is about 50¥ but mine needs loads adjusting and I need buy some proper chain lube of taobao at 20¥ a tin
Can try get DID O ring chain which is better
Don't bother with only chain no sprockets poor choice there
I have a CG150 motor I have 15 T front 43 T rear and think it's the limit
Check and replace steering head bearings but these are shit design just bike ball bearings 10-20¥
Head light let me know as I have issues with seeing at night and assed off already haha

All good points but check your A/F adjustment ??? lights ??? must fit H.I.D.

Bike stalls every 20-60minutes randomly. Easy to start up again.

When does it cut out ??? on tick over or when you are moving ?? and at what altitude does this happen

and change your air filter ??? could be running rich due to dirty filter
