[Discussion] DRZ 400 SM

[Redir]

hi there ppl,

 

been wandering, it it normal trying to start the bike several times (4-6 times) before the engine goes 'ON'?

 

been having this experience since i've got the bike, with the choke pull out, the times needed to start the bike will be abt 3-5 times.

 

the method of me starting the bike will be

(1) left hand clutch in (safety clutch has yet been removed)

(2) right hand standby to throttle in

(3) right thumb press the ignition button (sometimes, i pressed the ignition button for 2-3 seconds before letting it go)

(4) right hand throttle in once ignition button is pressed

 

is this the correct technique that i use to start the bike?

please advise.

thanks

Many DRZ riders are killing the starter carbon brush by pressing short half second bursts on the starter button expecting the bike to start.

 

Understand first that its a 4 stroke cycle single cylinder... meaning there is only one firing stroke out of the 4.. the others are the induction, compression and exhaust.

 

Only a 4 stroke, 4 cylinder engine has one firing stroke at any time that's why they start so easily.

 

It is not easy for the DRZ to start with one short burst on the starter button. Hold the starter button a few seconds and crank till the engine starts... it will save you premature wear on the starter carbon brush. Each short burst you do.. the starter carbon brush arcs and deposits more dust till it cannot turn the motor and all you hear is a clicking sound.

 

Disclaimer:

It costs $90 to replace the starter carbon brush... its your money and your bike.. do what you want.

Sorry Sir, I beg to differ..

Inline 4, the 2 inner and 2 outer movements in unison.. therefore, firing should be every 2 strokes??

Correct me if i'm wrong..

I've read the owner's manual n tere's a notice/warning regarding the starter motor. Not too sure if it's referring to the same thing here. It's read as:

 

'Engaging the starter motor for more than 5 secs at a time can damage the starter motor and wiring harness fr overheating.'

 

Sori Sirs, I'm posting this to understand n learn more. No intention of disagreeing with ur good advice. Dun reali understand wat the manual say actually.....

what Raptor means is not to crank the engine for less than a second tat kinda start. Press and hold not more than 5 sec or even lesser to fire up the engine. Appox around 3 sec range.

For most bikes is the same unless for kick start bikes

Roger tat bro SparkerS1. Tks tks

Luckily, I haven been doing the wrong thing. My way of starting is press n hold for abt 3-4 secs for it to start. One thing tat I nid to consult, during cold start, I usually only manage to start aft abt 3 cranks.....tat is without engaging the choke. Trying my best not to engage choke unless reali cold weather plus too many days nv start bike....

 

Is tat normal??

[SparkerS1]

Actually no harm done by operating the choke to start, just remember to off the choke after warmed up the bike or before moving off, if not the bike will stall halfway through the journey or even earlier.

 

My bike GSXR now is running on fuel injectors, auto-choke to make things easier

bleu> do u need to throttle in during yr press n hold for 3-4 secs?

If I dun twist the throttle, it'll be started only at the 3rd or 4th crank.

If I twist the throttle, sometimes 1st attempt can start liao.

 

Hope u understand wat I'm saying. My England Su(ks....

Correct me if i'm wrong..

 

Both could be on the up stroke but one is on compression the other is on exhuast, the other 2 going down.. one is on power stroke the other is on intake.

 

It is the firing sequence of each cylinder that is different. In the older engines... it was the distributor that determines the firing order.

 

But in today's 4 cylinder engine.. they use one coil to fire 2 cylinders spark plug at BTDC, with one cylinder at the end of the compression stroke while the other is at the end of the exhaust stroke.

thanks Raptor, Biting_point, SparkerS1 & Bleu for the inputs of the starting method for drz.

followed yr advices and WALA! i managed to start my bike in 1 crank. but then the engine died down. but its ok....on the 2nd time, the bike came alive.....

Hi all,

Help me tell your friend if any of them are interested..

Applicable method to use if the carb is a Keihin FCR flat slide. Each time you twist the throttle a small amount of fuel is squirted into the intake by the accelerator pump.

 

This method will not work on the stock OEM Mikuni carb which is constant vacumn carb.

hi there fellow riders,

 

is it normal for yr gluteus maximus aka butts getting numb after riding the bike?

im experiencing it right after i get off from my bike after my ride.

is it because of the nature of drz engine which vibrates that causes it or the bike seat?

should i change the stock bike seat into an aftermarket one in order to reduce the numbness?

if i do change the bike seat, which seat should i go with? SDG Step seat or DRZ Dual Sport seat as shown in the attached pics.....

 

thanks for the opinions....

[MaverickRD]

Guys anyone knows where could i source out for Talon Hubs?

Thx

I Had loads of that, especially travelling frequently from Joo Chiat to CCK... Its not only my butt that went numb.

I chose the other alternative, re-cushion & re-wrap my seat...

Done By Eugene Saddlery Along Jalan Besar...

 

Damage= $150 + ( i had to source a spare seat )

Comfort= 8/10 (compared to stock drz seat)

Time= Collect on the 2nd day (Do make appointment 1st, best during the weekdays. Shop Close by 1900)

Outlooks= 5/10 (you'll lose the streamline look as they'll widen, looks similar to the DRZ Dual Sport seat)

 

Hope this helps out... =)

it's very normal..

either tahan, change seat or change bike.. haha..

 

by far, the best comfort seat for DRZ is from seatconcepts..

it's not cheap, furthermore, they only provide the cushion and cover, you would need to bring it to staple to your stock seat pan if you dun own a staple gun..

But it's sweared by Americans as the best comfort seat around.. (forget corbin and gel seats)

that other photo you posted is the Seatconcepts seat..

 

I think I'm the only one that uses SDG Step seat in SG..

It's a race seat, period.

Rock hard as wood.. but my butt is used to it now..

Most likely would change back to stock seat if going long distances..

Hi Guys..

Currently i have a problem..I stopped my drz at a traffic light and as there is a massive jam, I offed the engine whilst the signal lights are running and power on..After about 30 secs or so..I tried to turn it on..It cant do so, I heard a clicking sound coming from the batt compartment near the left rear area. Is it batt problem or something serious??..really need ur help..The lights are still turned on but cant start bike..

[biting_point]

why switch off your bike in the first place?? EVen if it's hot, the fan will be on..

doing this will not save you much petrol but harm your starter motor/brush and electricals more..

 

Could you off your lights and start the bike??

how is the bike now??

 

Could that clicking should be from the engine area where the starter is??

 

get a mech to diagnose it..
