Cylinders on Amazon
Niche - Separate Cylinders - Brand new not re-bored. If you're just looking to rebuild your top end and get you back out on the track or trails, these are a great option that won't break the bank! I have personally used this kit in the link below and it works just fine for rebuilding a stock banshee. These take all the guess work out of pairing up pistons to cylinders with an all-in-one set up that include everything to do the job.

Cylinders on EBAY.COM
You will find just about every brand of cylinders on Ebay.. CPI, Athena is a big one, Chinese cylinders... Ebay is a good place to look if the Original Manufacture is out of stock.
Athena - Separate Cylinders, Good quality, I currently have a Banshee with these and they have never let me down (would recommend on a budget)
"True Tuned" - Separate Cylinders - cheap cylinders but they are backed by BPRatv who sells them from their site as well.

Cub - is the budget friendly cheetah (Drag Port timing cylinders) Used for top end power
"Cub" - ALSO when "cub" is added to Cheetah or Serval, it just means that its that cylinder (same port timing) with stock reed and head bolt patterns.... yes it is confusing, but it has 2 meanings, keep reading, you'll figure it out... ("cub" is just a BIG cat baby, hence all the big cat names: Cheetah, Serval, etc...)
Cheetah Cub - Mono-block twin - w/ stock head bolt pattern and intake pattern - (drag racing port timing) called a cub because it is the "baby version" of a Cheetah. Difficult to ride in an all purpose application. 64-68mm bore 347.43-493.90cc
Cheetah “Super Cub” - mono-block twin - (drag port timing) - stock reed bolt pattern, different head bolt pattern to allow for larger bore (also so the larger domes will fit in between head bolts) 72mm Bore
Cheetah - mono-block twin - Cheetah has a 6 bolt reed cage 250R intake reeds larger exhaust (1-900 is big bore) Cheetah Cylinders make the most horsepower with the widest power band of any aftermarket setup. (Cheetah can have power valves) 65-68mm Bore 358.37-396.85cc
Serval Cub- Mono-block- low end power (low port timing) Stock hook ups for intake and head. These are an all purpose cylinder, with great power at most rpm.
Serval “Super Cub” - Mono-block twin - stock reed bolt pattern, different head bolt pattern to allow for larger bore 72mm Bore
Wampus Cub - Mono-block twin - (drag port timing) made to look like stock cylinders but have Cheetah port timing. (sleeper, street racing style) 64.5-68mm Bore 358.37-493.90cc
(Wampus line is intended for the Rider with "stock appearance" being a factor in your cylinder choice. The Wampus and Super-Wampus cylinders gets their name from the Cherokee Indian word meaning "Ghost Cat", which seems to fit this cylinder with a "stealthy" appearance, disguising the performance that lies within.)
Super Wampus - Mono-block twin - stock intake bolt pattern w/ larger head bolt pattern to accommodate for larger bore (72mm) so head can seal to big bore cylinders. 72mm Bore 439.72-553.72cc
Cheetah DM - 72-78mm bore 472-611cc
Cheetah DMX - 84-85mm bore 642-771cc

Alpha - can come in stock size bore and stroke but is a monoblock - exclusively distributed from BPRATV.COM
POWER VALVES OR NO POWER VALVES
Banshee motor cylinders are truly impressive! When comparing motors of the same size, one with power valves and the other without, they will have a similar peak horsepower. However, the real difference lies in the power curve. The power valve engine boasts a smoother power delivery with a more extensive power band. On the other hand, the Cub engine has a narrower power band with a sharper peak. Power valve cylinders don't just provide increased peak horsepower but offer more mid-range and bottom end power, making them easier to ride without sacrificing the top-end power. With drag porting, you get a "light switch effect," but with power valve cylinders, you get an impressive, continuous power output.
