[Q] My speedometer will reset to zero when halfway riding. This will be followed by some vibrations on the bike. After awhile, the speedometer will go back to normal showing the speed i am riding and the bike no longer vibrates. This problem will come and go by itself. Does anyone know wats the problem?

Yap..its ok. Will go off after a few days..even a week or so. But it ever the sound gets louder and persisten...time to replace shim/shims or have vavle clearance done.

Hmmmm....since you got the bike eh? Why didn't you go back to the bike shop and have them done a free job for you. If you have bought from a direct user..then no choice lah..have to do valve clearance liao.

[Itachi]

any idea how much does it cost? what effect will there be? and which bikeshop recommended?

new wheel bearing need to put grease ? i just change wheel bearing but still got a sound from my rear wheel .

[arsonist]

theres a feeling coming from the front wheel of my spec1 when it rotates theres like a small bump coming every rotation of the wheel. im thinking

1 - brake caliper need to service? (brake pad i just changed)

2 - wheel bearing need to replace?

3 - brake disc need to replace?

 

bike doesnt feel like normal on the move.

Guys i got a question here.I kick into gear1,then i slowly let go my cluth till it bitting point.So once i reach the bitting point my bike will auto start to move forward right.So is it normal if,once i fully release the cluth the bike keep on moving forward without turning/touching the throttle.The engine wont stall and it keep on moving forward about below 10km/h.Till i press my brake to make the bike stop completly,then the engine will stall.

[thepunkz]

yes. it is normal. the bike will not stall if it has sufficient momentum.

when it is jerking means going to stall already.

[koxie]

[A] if need to go more, upgrade to a bigger bike lor...

seriously on a 400cc, 190kmh is enough man.

You can consider more extreme mods if u wanna go faster such as full system, bigger carb, big bore kit, yoshi cams etc...

but faster means drink more petrol
