Clinking sound doesn't always mean its broke or going bad. I was having the same problems with my ELA and Kick. Put the Kick in my Saber Touch and its going perfect.
Kick just has a problem with some MODs and only thing I can think of is my Saber has a very large contact area inside under the 510 connection so I is in constant contact. On the ELA the area is much smaller so I think it doesnt always make contact. I would have to shake my tube and it would make contact again, but it was getting frustrating so I took the KIck out, adjusted my build and perfect performance.
The same Kick is working
flawless on my Saber for at leat 15 hours. Needless to say ELA is firing perfect as always
Beautiful drip tip

I wish I had a friend that was handy like that. I do have a brother in law with 11 CNC machines and lathes etc. He is too busy making money that its not worth it to stop production to make me some little "bit"
