I am thinking of trying the ejk controller.I have a 17 zforce 800 with a uni filter and set on b2 setting.i don't really want to do a exhaust due to a lot of night riding.I pulled the tip of stock exhaust to see what it did I did  notice better throttle response but I think it's a little lean.it is a little louder but not like a two brothers would be.Just wondering what everyone's take is on the controller..Thanks guys!

Go for it I always think its a good idea to have control over your fueling. But I would get it dynotuned otherwise you are just guessing and could be running rich or lean and not know it.

I'm relocating and have my demo ejk tuners on ebay, let me know if your interested also I have a brand new Afr gauge for sale also. This will get you right where you need to go. It reads your air fuel and you can trim the ejk to suit your needs. Very easy to use. Good luck. Currently in China, not the best internet. I'll answer questions when I can.

I may be interested wheels what are you at price wise on the pair?

Hi how is the air and fuel mixture meter. Need to color a nut in the exhaust?

The items are on ebay , you can purchase them there and save a few bucks, the controller is used, the AFR gauge is brand new never used
The AFR gets hatched to exhaust , everything needed is in the box, very easy to use, enough dungs in the box for 5 units.
