I am trying to set up a keihin cv carb on my stock engine right now. It has a 45 slow jet and a 175 main jet with a nokt needle off a 1999 fxr2 I think; with two washers under the needle that were aproximately .024 thickness each. I am thinking of switching to a sporster needle [HD# 27094-88] with no shims to improve low end acceleration with out hesitation. Am I going in the right direction ? What are all you other guys and gals using in your bone stock fxrs

my FXR3 has a 45 slow jet, 175 main jet, sportster needle, and 2.25 turns out on the mixture screw....
I'm at 5,000 feet, if I were at sea level I would probably try a 180 main jet......

thank you for your response. I am at sea level and I will try the 180 main jet with the 1988 sportster needle that I ordered from Harley dealer . Cost $1.50 in shipping so I hope it shows up soon. I just ground down a flat blade screw driver bit out of a multibit screw driver so that I can possibly use it in conjunction with a 3/8 drive ratchet with a 1/4 " socket to adjust idle mixture screw through spark plug side of cylinders with out burning hands. I do plan on doing a ride this summer across British Columbia Canada this summer and I hope just readjusting idle mixture screw and idle will compensate for the elevation rise .
