JB series is quite the high revver... for JB-JL, it s on 8.5k oso... AFAIK, JB series are the same as Toyota 4A-GE in a sense they are co-develop by Yamaha.....

Ooh i see....if it was develop by Yamaha then i should not worry about it's performance ~

Sometimes feel like driving a VTEC or any high revving motor....on 1st gear 7K rpm is very easily to be achieve ~ =D

Sometime I oso worried.. imagine... a high revving turbo engine but came with RON95 as recommended octane.....

Once assured by my fren who work in Japan before, then I have no worries...

p/s: He owned Daihatsu Naked and Evo 6 there... until now he regretted in bringing the evo and not the naked... he says evo a dime a dozen here, but not daihatsu naked.... for sure can fetch higher price from kenari owners since daihatsu naked is the same chassis as Move L9

Haha yea...but now i fill it with 95 and 97 Mixture....coz at high rpm sometimes it knock because not enough fueling.....and no money to give it full 97 ~ hehe =P

 

[papagoines]

yep... its related to your fuel pump thread hehe

me think you just get

1. get the bigger fuel pump + good adj fuel regulator
2. piggyback that can tune both afr and ignition..

me think you can get good hp hike, engine response and still use RON95 hehe

[papagoines]
