Here are the guidelines; volume 60-80% of cylinder volume including spigot. Spigot diameter is 30-50% of carb bore. Between carb and as close to reed or piston port as possible. Larger volume =’s lower rpm. Smaller volume works for higher rpm. 2+ cylinders use a “log” type BB. You can post the guidelines for the ’pocket bike’ tuners.

Here are the proper steps taken to design one: 1. Make the connecting tubing cross sectional area around 30% to 45% that of the cross sectional area of the carburetor. (Area = 3.14 x radius 2) Yamaha tests showed that at 30% size the boost is 12% at 1/4 throttle, and 6% at 3/4 throttle.

How Too Use The Boost Bottle – Yamaha 2 Stroke – ThumperTalk

My understanding has been that it has to do with the inertia of air fuel hitting a closed reed valve, the boost bottle provides an outlet for the mixture to loop why the reed valves are closed and then head into the cylinder at full velocity when it opens giving the bike a better hit on the low end rpm range, not so effective up high in the rpms when this process happens much faster.

What does a boost bottle do for a 2 stroke? – 3WHeeLeR WoRLD

If a 2 stroke is ever out of tune (without a boost bottle or reeds) the air/fuel mixture will spit out the carb really bad, and you will even get exhaust fumes sometimes.

KDX200 Boost Bottle – Kawasaki 2 Stroke – ThumperTalk

I had enough wall thickness to make a decent radius on the long side but still added a little epoxy on that side also. Overall it’ll be around 10mm longer than the factory intake boot.
