The thing is , If you read Little Honda's post, It says the pilot jet is only for Two Strokes, Unless I have got it wrong ??, But I bet most of us have jets in !! My bike is running not too bad, And i can't face removing the jets and starting again. Funny a few years ago i loved messing about, But now i don't want trouble. I had less trouble years ago, When brother Ron and I built two 14" long Wal Philip type injectors. Cheers Bill.
I think you might have read that wrong Bill. The four stroke carb has a "bush" with an accurate hole through it that operates as a pilot jet. One of the many mods involves removing the bush and fitting a threaded pilot jet. Like you I have the 2 stroke type pilot jets and they work well.
