Review: Perfect fit for Keihin carbs -1995 Sportster 1200 - Direct swap - and fixed my pinging issue I was having on my 1995 Sportster 1200. Nicely labeled and no surprises. Comes with plenty of options in the jet ranges you’d want for both pilot and main. The bike runs much better on a 45/185 than the stock 42/170

### ⭐⭐⭐⭐⭐ Exact fit for the CV carb
*by D***N on July 26, 2024*

This kit had the jets that I was looking for. They are well made and marked well.. I have bought other kits from well known companies that were a lot more expensive. I wish that I had went to Amazon first to look or at least to compare.. The other kit that I bought at a much more expense, the jet that I wanted was wrong, the company did try to make it right, but they sent me the right size jet for the wrong carburetor, bless their hearts for trying... Overall, I would buy from this company again as there parts were less expensive, all the right parts were there, and they are well made
