Beta Tr34

Featured Replies

I am not a motorcycle mechanic and until I moved to Spain mainly had four stroke bikes.

However a friend has brought his Beta TR34 to me because it starts ok but bogs down immediately. year unknown.

I have dismantled the carb (Dellorto PHBH26  TD) and blown out the jets and airways but to no avail. 

Any hints and tips would be much appreciated.

Modern fuel + premix oil + float bowl not drained often means that you need to physically clean the pilot jet and its passages (rather than blowing air through)
