I have a problem I have a 2008 BMS heritage Znen150 .gy6 motor it started that acceleration problem now won't go over 10mph.
Starts and idles fine but won't accelerate. I have cleaned carb and jets, adjusted the valves, I tested my enricher it's working properly. What's the problem was running fine. I checked my hoses everything looks good nothing just lying around unplugged. My exhaust is cracked and has no fuel float sensor. I have ordered both to replace and will install when they arrive. Is this my problem? What else can it be. Please I need to get this back on the road it's my only transportation.

What do you mean by a fuel float sensor? Your problem does sound fuel related but it's hard to determine exactly what you've did so far.

When you give it throttle does it rev up or does it bog? If it revs up then I think your problem is in the CVT belt or weights. If it does NOT REV up but BOGS when you give it throttle then it is a fuel delivery problem.

So that problem never happens again, take that hose off the AIR BOX put a fuel filter on the end of it and zip tie it HIGHER THAN THEN VALVE cover. That hose is the Crankcase Vent Hose, if you overfill the motor with oil it will blow it out or if the HOSE is kinked or blocked and not able to vent it will blow oil out.

Now that you took that hose off the AIR BOX plug up the connector on the AIR BOX and YOUR DONE and that same problem will not happen again and your AIR FILTER will not get filled with oil.
