Well I went and ordered my boost bottle kit from Boost Bottle Industries, and when it finally came 6 days later ($14.95 shipping), It was shipped with the wrong manifold that was listed in the "auction". I contacted the seller and retuened the wrong manifold,and not wanting to wait 2 more weeks, I went to the Depot for fittings and tap. Got it installed and it is VERY hard to start, runs smooth at low rpm, but very poorly at mid and high. I have moved needle, checked for leaks, all is good because it runs fine without it. I have run boost bottles on most of my 2 stokes from 125cc up to 750cc and have notice considerable improvement. My next step is to remove it and measure the volume with marked containers that I use to measure proper amounts of fork oil. Since I got the wrong manifold (which is VERY obvious) maybe I also got the wrong bottle. I will keep ya all posted....
