Hi everyone,
I’m putting my airbox back together and I have a quick question about the hose routing.
Does the crankcase breather hose connect to the front inlet (the one facing the handlebars) or the rear inlet (the one facing the seat)?
Thanks in advance for the help!

The black large pipes on your carb = They go to the road (0verflow / breather)
For general tutorial for routing fuel lines , see below

Hello,
I am not sure I follow you ? The link is showing the tutorial how to connect fuel pipes from the Tank to the PUMP , then the carb
Your picture = Ignore the black pipe that is sticking out of the carb, just point it towards the ground (road)

Ahh okay , i got you.
For each nipple, hyosung puts a clear cap called “Airbox Oil Catch Tank Cap” like you see #6-7 below

However it is not a part easily obtained on its own, so grab a clear hose and clamp it there , then block the other end of the hose and clamp it.
At least both holes will tell you if there is oil deposits inside the clear tubes (about 4cm long max is good enough)
Regards
