wira stock extractor is 4-1
wiraSE stock is 4-2-1
i changed mine from 4-1 to 4-2-1 and i think the biggest impact is the torque is distributed more evenly across the rpm range now. previously it seems all the power is spread over a narrow band at very low rpm, forcing me to upshift very early, and power drops very fast as the rpm climbs. i'd suggest you go for 4-2-1 extractor.
yalor, if transplant, then after 2011, spare parts would probably cost a bomb. unless u can find NEW spare parts that you can use. but imagine gearbox spoil, or head problems, then die la. gotta find original, rite?

but disagree on 2012 thing.
