Hard starting! help!

[nightmar3]

Im riding a kr150 currently. However im experiencing trouble starting the bike after leaving it for sometime (about 6hours or more).

I have to kick like 20 times before it starts..

I pushed to bike tiam to find the problem, they tell me carb overflow. True enough when i off fuel tap when parking, i dun experience such thing. Thus i paid like $40+ to change a pin like thing in the carb. It really did solve the problem.

 

However recently, i began to experience the same thing over. and its been less than a month!! is it wrong diagnostic or the shop simply do carb servicing and con me?

 

In addition, my bike has a low side stand thus making the bike slant more than other bikes. Does this have anything to do with the overflow?

 

Sorry for my noob questions but i really wan to know the answers

most people start out turning too much of the trottle when kicking... it cause the carb to flood.. so yeah.. pratice kicking.. once the sound of its about to fire.. den trottle abit.. not too much... comes with practice.. and yes remember to off your fuel knob as well.. it helps..

 

small problem..

Hi. thanks for the tip. will keep it in mind.

However the carb overflow i was talking about was due to the cut off valve faulty. I just changed it but again the same problem surfaced. i want to solve this technicial issue as it is troublesome to always off the tap. whatmore i paid to fix it!!

 

I never trottle when starting not even abit as i know it will cause flooding.

 

I would like to find out if the cut off vavle is again faulty or any other possible reasons. i wan to fix the problem at its root

[Powieee]

During my sp days i didn't even bother to off the fuel tap but it works just fine maybe you should just bring it to another bikeshop to enquire . just my 2c

[nebulaz]

might need to change your float in ur carby...

[vTech]

when was the last time u changed your spark plug....?

[SparkerS1]

service carburetor and change spark plug, when engine about to start, throttle, then rev it after closing choke

[project.d]

Open your bike fuel cap and see inside your fuel tank got rust bo.

if rusty, then you need to do something about its before its lead to major problem.

 

there a filter in the fuel switch. its a black colour plastic located just under the switch. the filter filtration is coarse.

 

1. Off your fuel switch

2. use a spanner to open its.

3. when putting the filter back, dont tighten to tight. hand tight + 1/2 or 3/4 turn will do

 

If you find rust in the fuel switch filter, 100% is that your fuel tank alr rust and better do something quick about its. .

 

can either DIY to etch away the rust using chemical following by sealant or check with your mech whether they know/ can do it. else change new fuel tank which will cost about $300 from LAB

 

Lastly, you can use a fuel line filter. using the finest filter with plastic housing.

 

Fuel line filter is just a temporary method because if the rust is like powder form, its hard trap its in the fuel line filter

 

Rusty Fuel tank for KRR is very common.

 

good luck

Maybe the float closing is affected by the tilt of the petrol in the carb body. Try to adjust yr side stand so yr bike is more upright ? also, better if shut off the fuel petcock overnight ... i think some bike manuals do recommend. Engine flood is the worst .. takes long to settle. smell for the petrol coming out the pipe... if can open sparkplug smell the petrol from the hole & look at the tip see if black/wet/oily. If confirmed engine flood, open throttle wide & kick with Engine siwtch "OFF", will help to blow out the petrol in the cylinder

hey hey riding KRR as well .... have the exact prob ... my side stand bend making my bike tilt more than normal ... kns ... went to my friends dad shop ...said is the carb air intake too low then 2t output too much ... but after tt still the same prob !!! so thinking maybe is the stand ??? all my friends riding krr but no such prob ... n their stands are the normal stock stand ...

[kito]

why don't u guys change to a stock side stand for a while and see how it goes..

[cheezeSeed]

hmm ... guess i'll give it a try eh ...

[bapecraze]

for me if my SP is hard to start especially in the cold mornings..

 

But the way i use to solve this problem is by putting choke when i start n close it back after the engine started and use the throttle to "maintain" the rev at 1.1-1.2 rpm and let it warm up awhile..

 

I'll think that it's the problem with the engine when it's "cold".. so just warm up the engine abit and should just work out fine..

 

Just my 2c tat u can use as reference..

[adesmond2]

hmmm, my advice is to get Broquet at http://www.singaporebikes.com/forums/showthread.php?t=152414&page=8 this link... keke... Cause It really improve my engine quite a lot... FC CONFIRM better... Smoke also reduce but... overall still depends on our riding patterns... Rev at the correct way... dun play too much... ^_^

once you choke start, turn the choke off don't trottle for a few sec let the engine heat up itself before you start playing ur throttle to warm up, what i usually do last time during cold or after rain weather is.

 

Choke Start then once started, off my choke, let the engine run a few sec and leave it for 2-5mins for the engine to heat up before i move off to work.

[cheezeSeed]

ok ... but it seems tt even if i park the bike for more than2 hrs i have to on choke le ... if not must kick till don't know wat time ... hais ...

[adesmond2]

hmmm, maybe can kick and rev and see? I used to have this problem but now it seems alright... remember to off your fuel when leaving your bike more den 1 hour.. that's what i do everyday.. Now it seems better then last time... Morning can start with 1 kick w/o rev...

Bro i got the same problem with u bro,Pull CHock also cannot start one.but mine is SP,and my problem is solve already,,,as for my problem it was my wireing which was short circuit at the OFF ON Button switch there.so right now i cannot use the button cos they connect it direct to the starter thing like tat.so maybe u can go check your wireing bro..

[madman]

why dun you learn how to do a push start? for a 2b bike, it's not that heavy and rather easy to push start.

 

sometimes, it could be the pin in the carb is off position...hard to say...hahaa...
