rocker1 Posted April 24, 2023 Report Share Posted April 24, 2023 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. BC.

feetupfun Posted April 24, 2023 Report Share Posted April 24, 2023 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) Quote Link to comment Share on other sites More sharing options...
reggie Posted April 25, 2023 Report Share Posted April 25, 2023 Did you clean the fuel filter on the carb? Quote Link to comment Share on other sites More sharing options...
