Machismo, how did this turn out? I've read in a UK forum that a few folks have left the 15 pilot in, 120 mainjet and removed 0.8mm off the bottom of the slide; essentially a smaller cutout. So, I was curious how your dialing in has gone and what adjustments you've made from the above.

Dan, could not update the post for a long while. Apologies..
So here is where I stand: My BS29 showed scores on the carb piston so decided to go for a new carb.
I did not have a lot of spare bucks hence went for the BS32 carb which cost about $50.
Changed the main jet to 120 and the pilot to 17.5. Needle notch untouched. The air screw is about 3 turns out.
Mild popping sometimes, pulls good and bike doesnt overheat. Havent tested the top end yet as the bike recently underwent a bottom end overhaul.
I have now understood that this bike is better off with the stock air filter. So took the K&N off.
Recently, I made the catch can deletion mod and hence had to plug the vents on the air box and timing chest.
This makes me go for a single piece manifold hose to connect the air filter and the carb - idea is to get rid of the shitty pieces of rubbers that crack every now and then, rather better to have a good quality single piece of hose(probably a car's radiator pipe) and also to minimize the chances of air leak in the whole circuit by eliminating the air box.
So I will have to post an update on the bike's performance only after completing these changes.
Hopefully, this weekend should be it.
