Freestyle whats the difference in a lamey cylinder?

[jetpilot36]

hello.i have a noob quesion to ask.what is the difference in a lamey stock stroke cylinder vs a yamaha 701 or 760?if i understand right,u can buy a lamey with or without porting.with or without billett,with or without power valves.
so if i got a stock stroke lamey non pv, non billett cylinder,what would be the difference over a stock yamaha if neither are ported?sorry about the noob question,just gotta get some knowledge on the lamey stuff.

7 ports in a Lamey sleeve vrs 5 in OEM and you can run Kawi flattop pistons as well as OEM style yami pistons in a Lamey.

I beleive you can also still buy Lamey sleeves for your OEM cylinder if you like, less prting room in the casting of the OEM so prolly not as much room to let them breath.

i see said the blind man,but in reality...he never saw at all.

so the 2 extra ports make a big difference?

They are smaller, but yes they make a difference. Just that much more fuel/air that can be pumped into the cylinder. Also you dont have to run a girdled head with a Lamey/DASA cylinder(billet or cast) since they are much beefer than the cast OEM cylinder. There is also the advantage to have exhaust power valves too.
