Guys, seeking help of all lao jiao bikers!!


Recently bought a CBR 400, its a R model, at first i got it, very smooth and powerful, got yoshi end can plus hurricane header..


however after i ride it for 2 weeks, the header(extractor) cracked and split into two, lucky i was at low speed.. about 50kmh when it happened, in the end had to weld back the header(extractor).


After welding back the header, my bike is never the same ever again, it is SLOW, not responsive, the RPM 4 to 7 time like wanto die lidat, and the whole bike jus no power.

Dude, try posting in the 'Babyblade' thread, lots of cbr 400 riders there I'm sure someone can help u. My advice, go to a trusted workshop that deals a lot with the cbr400, there could be a host of things wrong that we can't pin point on a forum. The problem could be with your header, carb, cdi, engine etc...

I used to be a car person. Then one day, I woke up and became a biker.

Ex rides:

Nissan Sunny 1.6

Nissan Cefiro 2.0

Honda CBR 150 R

Honda CBR 400 RR Fireblade

Current rides:

Yamaha 2008 YZF-R1

KIA Cerato Forte 1.6 Well OK sometimes a car comes in handy.
