Troubleshoot ur Super4!

[bigboystoys]

Hi guys, I got this problem and wonder if anyone knows where the fault is:

 

After running at say 120kph for an hr or so (e.g. Malaysia), then stop and switch off engine. Once in a blue blue moon when try to start, the bike refuses to crank at all. No cranking, no sound, nothing. Have to push start. One week ago, this happens again at Batu Pahat. Brought bike to bike shop there. Mechanic checked battery (quite old) with meter. OK leh. Got light, got horn. He then thought the fault lies with the starter button (dirty?) or the starter relay (at the side of the bike). He then clean ** the starter button and the bike starts again.

However, last night at GP, same problem again. Have to push start. After coming home, when the engine is still hot, switched off engine and start. No problem leh. Bike started beautifully.

 

So guys, anyone knows where is the probable fault. My query:

 

Can the starter motor be at fault? But cranking sound is always good. When it cranks, it doesn't sound problematic and bike starts easily.

Will the starter relay cause such occasional problem?

What about the kill switch button...Can it cause this problem

 

I would appreciate if anyone can enlighten me more on this occasional problem.

 

Funny thing is, this problem occurs only when the engine is hot.

 

 

 

donno if it's a similar thing that happened to me...

i tried to loosen and tighten back all connectors/bolts that hold the power cables to the starter motor... didnt work but after i removed the Ignition Start fuse and clean the blades and put it back in the fuseholder... it worked wonderfully... yeaa sometimes the wiring are old and needs a little bit of re-working... but careful tho... the rubber protective sleeves on some of the connectors could be really fragile

 

mine is a spec1.. so it's been ard and seen some beatings...

Hi all brothers,

 

Got a big headache, wake up when i wan to go to sch, my s4 cannot start..It does n't look like battery problem as I had change one less than a year ago. Tried to push start for very long but still not successful.

 

Could it be due to spark plug? What can i do now? Cos it cannot start and i cannot ride to bikeshop to repair, really headache..have to take bus now.

 

Pls advise me follow bros of cb400!

 

thanks a lot..

 

Just curious: Did you use the correct push-start method? If method is wrong, push until next year also won't start.

Should be normal... But to see the black smoke, most likely your rpm is more than 7? Would advise not to ram your throttle during stationary too often.

mmm same problem as mine.

its the brake caliper if not is brake pad going to finish liao.

brake caliper need to service which cost around $60 per caliper, change the rubber thingys inside.

[E.M]

mmmm i also not very sure...

[khoa9876]

they will change the seals set of calipers but I'm not sure that the problems are from calipers.

 

@carbon starter is only for starter system, it's not affected to transmission system.

[patrick1131]

can anyone tell me what is the relay rating used for horns??

[hellsfury]

past few days while riding, i noticed there is a creaking sound coming from the front of my bike whenever i make a slow turn or brake at low speeds. could it be steering cone? i ruled out the forks cos i serviced it last month.

maybe u can try checking the wheel bearing...

[hellsfury]

cant be wheel bearing cos i experienced it b4 n i changed it 2 months ago.

How's your brake pad doing?

[vtec power]

when my bike is idling the rpm at 1k is moving slightly up & dw by a little. Wat's wrong? Tuning problem?

Hi guys,

 

when i'm in gear 1 or 2 accelerating, and i close throttle and clutch in... then i release clutch fast (but not to the extent of throwing clutch) i felt the engine-brake. but... this feeling is VERY rough. not "smooth" kinda pull-back feeling.

 

it's really a very ROUGH sound. sounds like engine seizing or piston going to jam or something. but it's alright when i whack the bike or ride the bike normally.

 

it's only when i clutch in and release clutch fast after i close throttle.

 

have anyone experienced this problem? can anyone help? BTW, this is a spec 2 bike.

 

Also, just wondering, how reliable is a patched up front tire? as in, a rubber thingy was inserted into the tire to mend up the hole. will normal riding at 90-100kmh causes the rubber thingy to dislodge or pop out? i've seen a bike crash because of it b4. so just wondering here - just how safe is it?

 

Thanks for helping with the answers! =)

Hi to all S4 Bros,

 

I am riding a SPEC III, recently I found out my speedometer suddenly point to 0 KM/H and back to normal. The problem is intermitten. Sometimes when travelling at 100 km/h the speedo will drop to 70 km/h and INSTANTLY back to 100 KM/H.

 

I was wondering if it could be due to a loose contact sensor or wiring.

 

Any bro can provided valuable advises?

 

Thanks in advance.

 

Regards,

Pau

dunno if dis is ur problem. just sharing. others plse comment.
