Hello one of my KZ is running a stock 1015 engine that I build to have a reliable bike, now I Broke the engine in and thne swap the cams for a Z2 drop ins and is runnind a mac 4 in to 1 mac with the Kerker wider baffle , is running a set of 26 mm stock carbs with velocity stacks, pilots are 22.5 and mains are 140, the spark plugs are the right color tuned and performing good but I am going to upgrade to a set of RS 34 that come from factory with 17.5 pilot and 115 main, I have stacks for them as well so I was wondering where should I start with the sizes for the tuning as I think that is going to be craving on those sizes.
I did a s light porting when I did the engine aside from that the engine is stock.
Thanks

If I'd known better after redoing my 1100 Shaft KZ top-end in 2015, I would have worked toward rich from the lean end.
I'm doing it that way this time.

The RS34 will be pretty close on being jetted correctly right out of the box. The 17.5 and 115 will pretty much be spot on with your setup.
