50 Motorcycle mechanic in Auckland Region

Bike was fully submerged in creek water in Mangere East. Managed to tow out and get home. Will need an overhaul on everything. Bike is not physically damaged but I am guessing electricals are not good? Have taken the battery out immediately when we got bike home. Please help, Cheers :)

My moped has been running fine up until a few days ago. Where it started vibrating somewhat aggressively and it's been performing lower than usual as it's slower uphill quite significantly and then today it was so slow going about 40km rather than the usual 60km until it came to a halt as the engine gave out. I've come to the conclusion that it might be due to the piston rings deteriorating.

After motor starts, fuel leaks out of overflow pipe. Like carburetor overflows n does not stop. As u accelerate motor goes off. Bike was stored long time
