I have a stock 1971 Honda cb350 and these carburetors were jetted well enough for the engine to run without any changes to them. The jets; however, will most likely need to be fine tuned for the engine to run properly.
From what I have checked so far, this kit includes the following:
Mains: 140*, 145, 150, 160, 170
Pilots: 40*, 45, 50
Needle Jet: Have not checked yet
Jet Needle: 6F5* at clip position 3 (middle)
Throttle Slide: 3.0*
*Included inside the "pre-jetted" carburetors
For my bike in particular, I need leaner pilot jets (this kit only includes 2 richer pilot jet choices) and possibly a richer needle jet (only one needle jet included). So, prepare to spend a little extra money on some new jets. I am confident that these carburetors will be perfect after I jet them correctly.
The throttle cable did not work for me at all. I cut and assembled it properly, but it had a real tendency to stick and resist any motion to accelerate or decelerate the bike. I ended up modifying my original throttle cables and that worked out perfectly.
