Thanks for answer, Petenz, I already have a 2into1 exhaust, BMC filter and PCIII with custom map, snorkel out, AIS removed (51,3hp on the dyno) and I�m looking for more improvements.

So if I can lose 2-3kg I�ll be happier!! My bike with OE battery can stay 2 weeks without start and no problem, is the same with lithium batteries??
