Hi need your advice. I just picked up my spec 3 and there seems to have vibration to the point the side mirrors vibrate so much it is difficult to see. I can also feel the vibration thought the handle bar and my seat. This happens when I am moving more so than stationary.....is this common or something to worry about?

If you are facing this problem, most likely your bike is not fixed with the original mirrors.

Original Mirrors dun face such vibrating problem unless the mirror piece is loose.

 

And yes it is something to worry about cos you have difficulties checking back while riding and it is dangerous.

Pls check & change your mirrors ASAP.

 

Ride safe

Need some advice. Recently took up a spec1 and i had idling issues, could not idling well and engine dies off easily(cold & hot engine condition).

Went to service my carb and replaced the injector pins(correct me if i am wrong) and spark plugs.

Rode about 20KM and realized that my idling is not constant at all, tends to have a pause in between and after every pause, the timing seems to be unsteady.

After my carb was serviced and noticed that at 6.5rpm my speed is at about 120, Vtec opens at 7rpm still but my speed is at about 125-130. Initially before service vtec opens at 7rpm - 120KM/H.

Please advice if this is abnormal/good or bad, thanks in advance!

Dear All

 

I have just acquired a 3rd hand Honda CB400 Spec 3. I have a few questions to consult, please advise.

 

1) There is this 'gurgling' sound at the coolant reservoir after i have off the engine and park the bike. Is this normal?

 

2) There is this ringing sound when i reach 100km/h and RPM 6.5 (but not at other speeds or RPM) near the front of the bike, what could be the possible reason.

 

3) Where can i get a windscreen for my bike, preferable Givi one other than LAB?

 

4) Where can i get a mesh for my radiator? No need design, just plain ones will do.

 

Many Thanks

1) sounds like boiling of coolant to me.. check for ripple mark on the cap of reservoir.. boiling should means coolant not circulating

 

2)ringing sound? vtec sound? check if pillion footrest loose, applies to me..

 

3) try unique motosports

 

4) try cmo.. u can rfq but don expect the price to be below 40.. unless u diy

Hi guys, just replaced new batt for my spec 1 on 8th dec. Previous replacment was 15mths ago. Then this morning bike cant even start. Last rode the bike last friday. Cant be 4 days of inactivity can drain bike's batt right?

 

Only hv volt meter and pivot voltage stabiliser tapped to the batt n i doubt these are batt suckers right?Possible that the shop did a lousy installation or gave me crap battery? Wonder whats my chance of getting free replacemnet if any...? Or cld it be somethg else that needs to be replaced? Thanks in advance!

[jayz]

Did they test ur rectifier?

 

If rectifier spoil, change battery also no use cos it wun charge the battery.

No they didnt. The mech actually asked me to remove the voltage stabilizer instead. Haiz...

[jayz]

So how ur bike now?

 

Try push start then ride to bike shop check loh. If cannot then tow bike. Or if u can jump start it...

Either ur rectifier, rectifier connector or coil or all three or eother two koyak liao. Basically..ur new battery is not being chatge. Forget about ur voltmeter...it's useless and non accurate.

[NaZ23]

Dun hv the tools to jumpstart...think lan lan must tow. Dun feel like towing back to same shop coz i feel the mech there didnt do a proper and thorough job. Sucks man.

 

To Ah Pek...wah lao if really kena all 3 faulty sure very expensive sia the replacements. Any idea if this kind of problems got symptoms for us to prepare for servicing? And any good shops to recommend to replace at? Many thanks in advance...
