The Honda PCX / Forza / ADV150 / SH Forums

Just fitted the stock exhaust and still got the same noice.

But the temp level does increase and reduce. So relay?

short the temp sensor wiring harness? Is their a digram for this?
Btw this normal on forza's the fan to run when the ignition switch is turned on and temperature sensor plug is unplugged?

Issue fan didint turn on when overheating. Trouble shooting process. The fan works when powered by a 12v battery.

Decided to stop half way through and the moment I stoped the bike, coolant started to poor out not sure if it was a hose leak/crack or was it just extra coolant overflow.(Will check and update)...

Seems to be like the inner part of the exhaust is broken even the DB killer was laying inside the exhaust so their has be some chipped parts inside. Thanks for the info btw

Sounds like a leaky exhaust header gasket. Or belt slap. How many miles on the belt? Any aftermarket parts fitted? How does it sound with the cover on? The bike had been left aside for 8months.
