Its becoming popular because its a much better system for carburation. Mind you these engines have had them for a while ..

The problem is not that there is a long LSN , Its the Manner that people tune carbs ... The biggest problem being perpetuated on the net is incorrect tuning procedure. You can see it all over You Tube and Forums alike .. People tuning the HSN first is the road to a bad tune. No matter what carb you have on no matter what engine you have you MUST tune the LSN and idle gap relationship FIRST ! then tune the HSN then re visit for finer tuning when the engine is at temp.

the Long LSN is a much smoother and more economical form of metering the fuel spray. Thats why its being used. As people want better economy out of their engines the need to regulate the fuel intake becomes greater. LSN's are the only way to do this without bolting an ECU onto your engine.

MASSIVE !
