[Q]hi guys,

i am riding spec 3 2.5year-old bike.when i start my bike the battery reading is only 12.5, and when i rev a bit to ard 4000rpm it reads around 12.8 only.

isn't it suppose to be above 13v??

my battery is shinko brand size 10 used for almost 10 month,rectifier and magnetic coil never change b4..

what could be the problem???

 

Bro how you take the reading?,using a multimeter or just by reading your analog voltmeter?. Because the reading on analog voltmeter dont give you good reading,its best to use digital multimeter.

thanks for your reply bro.

i was using a multimeter ,meausre directly on 2 terminals of my battery

Hi to all, need some help here, Im gtg to buy a Specs 2(bike shop)selling at $6500 FX plate with Yoshi pipe is it ok?

[phill]

My bike is 7 years old spec 1

 

My exhaust pipe very sooty leh. this is most probably cause by carb.

then i went to service carb.. problem still persist.

 

my FC is ok lor 20km/l but this sooty pipe juz annoys me. i seen spec 3's pipe very clean. ride very long already the pipe there still not much soot.

 

1.does this mean i should go for a valve clearance check?

2. install jet kit will help this?

3. valve clearance job consist of wad? valve clearance only? wad about timing chain etc?

1.Valve clearance only done when you hear the "ticking" sound when engine is running.

2. Will help but still you need a dyno machine.Why not use original jettings,unless you got install aftermarket exhaust system.

3.Valve clearance job consists of setting the correct gap between the tappet and valve tip by adding tiny spacers.Timing chain will last you about 100,000 or 150,000km.

 

Hi,you mention about washing carbs,but what about the airfilter?.

Yes O-rings were changed, both disc brake is hot, only right side one is hotter than left side one.. I was wondering if anyone else is the same cos i spent ard $400 doing up my brakes already..

i also did the same servicing as you,indeed right side is hotter than left,so think should be normal ba.

Here goes...

Just changed battery (yuasa 7A) and rectifier ytd, wired up a dynamax voltmeter and here are my findings....

 

On the move RPM 6

MAX Voltage headlights on = 12.5V

headlights off = 13.2V

 

Idle @ RPM 1

Max headlights off = 12.0V

headlights on = 11.7V

 

Readings will reduce by 0.2V if signals were on at any set-up...

 

 

The question now is... is everything ok? it seems that the voltage is not at the optimum, what else cld be the cause?
