The Kipor generator is now working. It had a spark and fuel but died after only running for a couple of seconds. Logic suggested to me there might be an air leak somewhere in the fuel system so I removed the carburettor and smeared gasket putty on the gaskets before reinstalling the carburettor and waiting 24 hours of the putty to harden. A simple fix!
The swimming pool equipment distributor sent me a new chlorinator element to see if that would fix the problem with the pool. It was partially successful. The system is now producing chlorine but the ORP reading (a measure for reading the level of chlorine) is blank. Something is wrong with the system and the supplier doesn’t know why. In the meantime I drained and refilled the pool which has removed the murky water.
The bike has started skipping when I place it under heavy load (eg, pedalling uphill). It can’t be the chain as that is new. I think there are three possible causes. Either the front chainring or the rear sprocket is worn. Something is worn our out of adjustment in the internally geared hub. The sprockets or clutch in the Bafang electric motor is worn/defective.
The hub would be the most difficult to identify and fix. I already have my original hub in bits on the workshop bench as a jigsaw puzzle. The motor would be the next most difficult component so I looked at the chainring and rear sprocket.
I’m hoping it’s a worn rear sprocket.
The old and a new sprocket. The teeth on the old sprocket appear to be worn on the leading edge.
Old
New
I’m guessing (hoping) this means the chain jumps off the worn teeth when the chain is placed under heavy load. The rear sprocket has done 8000km so I should expect it to be worn.
I’ll go for a ride and test my theory.
