CB750 K3 carburettors

Hey folks!

I'm rebuilding the carbs on my Honda CB750 K3. I have drag pipes on the bike and am going to replace the old air filters (no airbox). Do you guys have any pointers on what jet/needle sizes to go for? I think I'm going to try use pods, unless someone here has a better suggestion of what to go for

Thanks in advance!

So I've read from places like Carpy's cafe and other sources for a mild mod (pods and exhaust) that 125 is a good place to start for the main jets. A set of four is pretty cheap about $25 so it maybe a good idea to grab a larger set and see if your bike likes a 130 or 135. But just running stock mains without an air box will def lean it out. Hope this helps
