As per Simon, he is correct on both replies. Nothing to worry about here , they face the road indeed.
However….
If you have a carb bike, please check your carb top diaphragm covers must have 2 tubes joined to 1 long long long tube that travels to the rear of the bike then faces down to the road.
Carb Bike has 3 overflows/breather zones mainly
- Fuel Tank – As per your picture and simon’s confirmation.
- Engine Overflow/Breather – As per your picture & simon confirming it too.
- Carb Unit – if unsure take a pic of BOTH sides of the carb (front and back)
