In Feb. I purchased Treats new 15-Bing (clone) with correct 2.17 atomizer and slide 50 bucks...and I am glad I tried it... as I replaced the worn out original 15-Bing and it actually out does the original purrs like a kitten at idle up to WOT...and is easier to restart when hot even...I plan on buying another for my other bike...The casting looks good too...
