Hello Zenfidels, here is that modification that Zen~ mentioned recently. I did this because I personally prefer a stiffer draw and have read that there are others who also prefer this so I wrote up how I tightened the draw on my Zenisis in case anyone else wants to do the same. He went over alot of what this does and the possible risks in his post so I'll just get right to it then
You need a dremel with a grinding cutoff wheel, an 18 ga needle, a VERY TINY drop of super glue, a fine pointed prescision file and a standard Zenisis cap.
What you need to do is use the dremel to cut a 1/8" piece off the needle. Use the file to make sure the ends of the piece you just cut are clear and to hold this tiny piece of needle securely.
Test fit the needle piece to the Zenesis cap. It should fit right in the hole with almost no play, but not snug. If it fits as mentioned, you're ready to set it in place.
Take the tiniest drop of superglue and put it on the outside of the needle you just cut off, being careful not to get any on the file.
Put the glue covered needle into the air inlet on the Zenisis cap till it is flush with the outside of the cap and hold it there for 5-10 seconds. The glue should set almost immediately.
Now pull the file back out of the glued together parts and put the cap back on the Zenisis.
Give your Zenisis a test vape. If you did everything right it will now have a tighter yet comfortable draw and should create a nice vaccum in the vapor chamber that will prevent dry and harsh hits.
If you decide to try this, please be careful not to damage the finish on your Zenesis by using too much glue. Remember, less is more in this situation.
Good luck and happy modding.
