Hi bro, I went FJT and bought the bulb replacement for DIY. After changed, realised it's not the bulb issue. Normal and high beam no light but flashing can. Wire issue? Thanks and have a nice upcoming weekend.

Check your wiring loom inside the headlight

If ur right side switch assembly is very old or have cracks on the ON/OFF see-saw toggle switch..tape it up and open the two half partially up (via 2 small Philip screws under it and spray some WD40. Do the same for the horn and headlamp ON/OFF switch as well. If this does not help..could be wiring connectors not proper or wet in the headlamp.

I just encounter this problem. Might be your ignition switch stuck halfway after starting the bike. Check if its stuck, if it is pull out manually and the light will light up.

[richard3121sg]

Thank you very much bros for the advices...will try it out...have a nice weekend

Did what you advised....light never turn on...went to bike shop. At the bike shop when mechanic turn on my ignition light suddenly become ok. After changed EO, light don't on...shop advised me to change the whole right side switch assy. Any advice whether can be repair? No crack.

Hi all,

I have a cb400 revo.

Sometimes, when I start the bike, the speedometer jump around and then go to zero ( just like when you turn the key to the on position).

Is this normal?

[voong]

your battery going weak .haha time to change battery.

Hello fellow wanted to know how many kilometers each adjustment of valves is done on a cb 400 sf spec1 vtec . My bike has 49.500km and I think he has never done . Wear it with 10,000 km and its operation is the same as the first day. Thank you, greetings

There is nothing to adjust..the bike is using "Shims" with Cam follower and not Rocker arms like the old days bikes. What you have now and runs ok..don't bother..nothing breaks don't touch...sometime touch you break even more..LOL! Do it only when the shims (16 of them) starts making loud noises..a few occasional ticking sound here and there is ok especially after warm up and it goes of. What you read and heard and dunno who told you is just a reference. No 2 bikes or riders are the same and so are the conditions of each individual bike. Safe the money..what you about to do can cost easily up to $600 at least..it's call top overhaul. My PB1 been coming 19 yrs and getting trash happily everyday..just be sure u do ur eo and coolant maintenance well.

seeing your problem it is very similar to mine. i did the same thing of spraying wd40 and it worked for me. maybe you can give republic motor a call cauz the mechanic over there taught me how to do it. you can find their contact on the advertiser section.

 

i'm not free recently.. rushing my uni fyp haha if not i can offer to help you take a look.

Hi guys, speaking of ticking sound, if sometimes at idling there's a ticking sound from the right side if the engine, its not a good sign right?
