Atomik Nitrous 140 starting problems

[Flynn629]

U rekon the plug ae? If it was faulty wouldnt it not be able to start at all?

 

[Flynn629]

Also i just took carby apart again and should the carburetor be wet inside from petrol? Because it was bone dry dont know if thats normal or not. Also all the fuel came out of only one fuel line and none at all from the other. Please help thanks

A dodgy plug or china plug can give ya a big headache, sometimes the spark will be pushed into the plug under compression a bigger than normal plug gap can play havoc also. While you have the carby off hold the fuel bowl on the carby(without screws in the bowl) and attach it to the carby and wait 10 sec then remove the bowl and see if there is any fuel getting into it.

 

[Flynn629]

Do u mean turn the fuel tap on and then see if any fuel is in there? Should there be fuel in there or not?

if its a chinese crap plug, it can give ir-regular spark, sometimes allowing you to start and other times not. grab a genuine ngk cr7hsa, they are cheap, and your bike will be alot easier to start.

another thing to look at (may have been mentioned) does your spark plug lead have any kinks or places where its been melted away abit ? if so, it can cause your bike not to start, or have problems starting. the stock leads are not too good, if i were you, i would grab a chinese copy of an ngk spltifire lead. they are much better than stock lead. they give a stronger spark, and a more efficient burn. i recenlty bought one for my bike, and noticed a difference in acceleration compared to the stock lead.

 

[Flynn629]

Do you think this is the whole problem why my bike wont idle and wont start?

 

[Flynn629]

My coil have many kinks in it where it has been melted by the the oil cooler spring things. Should i get one of those also and a new spark plug, do you think this will fix the not starting? Have u watch the video i posted of me trying to start it? This might give u a better understanding. Thanks heaps

 

[Blender]

it could be contributing. you never know, it could be the problem, stranger things have happened, lol, but i would suggest doing things that have alrready been mentioned above, e.g, cleaning carb, checking for vacuum leaks, setting valve clearences etc. if those things arnt properly maintained/adjusted, it can make a bike live a shorter than necessary life.

 

[Flynn629]

Ive cleaned carb like 3 times and checked the wholes in jets and there all clear, i haven't checked clearances as i don't have right tools and the feeler gauges, what are vacuum leaks? I might get a new spark plug and spark plug lead and then if it doesn't start ill have to take it to a mechanic

if you mean your coil lead, then yes you should probably look at getting a new lead asap. but, in the meantime, if you have any electrical tape around, tape around where it has been burnt/melted. try and wrap it as tightly as possible. this can somethimes fix the lead if the burns arnt too deep. your plug may already be a ngk, but from the sounds of it , you could do with a new one. just watched your video then. i think it may be a fuel/carbuerettor problem.

what are vacuum leaks?

these are leaks from around your inlet manifold, and carb. they are called vacuum leaks, air leaks etc. basically all they are is a leak, as a result of a warped inlet manifold (at the base), or dodgy gasket, or loose bolt, allowing too much air to be mixed with your fuel. resulting in it running alot richer than usual.

a good way to check for air/vacuum leaks is to spray some inox ore wd40 around where your inlet manifold connects to the head and carb. if you see any bubbles appear when you kick it over , you know u got a leak.

 

[Flynn629]

Mm, what do you recommend me doing ?

 

[Flynn629]

Ok wll try tomorrow, what do you think the problem is after watching the video and what do you think i should do?

All of the above would be a good starting point. im not to sure that that is what is causing the problem (lead wise anyway) but i think all of those things (valves, carb, and lead) could add up, and cause your bike to run/start badly.

Btw feeler guages are around 5 bucks from supercheap

 

[Flynn629]

Ok will try these tomoro then will see talk after that cheers

 

[Flynn629]

Although it does start when i give it gas on statup but it wont keep runjing unless i keep reving it, do you know why this could be happening?

 

[Blender]

have you adjusted your idle screw? it should idle at around 1800 RPM.

 

[Flynn629]

How am i meant to know if its at 1800? Ive like screwed it quite far in and far out and it makes no difference and also makes no dfference when i moving mixture screw around a little bit, heres some pictures of the carby does everything look alright?

 

[Blender]

well, theres nothing alarming (apart from the missing pilot jet of course) but i see you have taked your manifold off aswell. there should be a gasket between the base of the inlet andf the head. when you took the manifold off, did you make sure to keep the gasket on the head? did it tear at all?

 

[Flynn629]

So is there a missing piolet jet? There was a small thing at the bottom of the whole which screwed out and had a hole through it but it didnt have the small hole going through it sideways. The gasket is still on there and its in good condition. So i just need new carby then?
