Needle Comparison DDK vs NE1F vs JD blue

Been meaning to do this for a while so hope it helps someone.

Explained why the DDK is so much less sputtery at very low throttle openings - great for green-lane use and excellent fuel economy.

Also explains why the NE1F is terrible fuel economy, sputtery and only clean in mid throttle openings.

I didnt like the JD blue first try but will find a larger main jet before trying it again. Its possible theres nothing wrong with it other than it may not be suited to the type of use my bike gets.

Note based on running tests with an EC250 2005

Enjoy.....
