Thread: Sparkplug

  1. #1

    Sparkplug

    Okay well as you all know I have had some problems with my bike.. Fixed a wire, changed a fuse, and my lights and stuff run fine..

    But...

    Now its EXTREMELY hard to start.. I've been told to change the spark plug which I have done just now... I rung Maunders Suzuki and they had told me to put a NGKB9ES spark plug in it.. The one I took out is a NGK BR8EIX, now I am confused.. Can anyone fill me in on that..?

    Also.. I have found a black and green wire, I'd assume this is an earth wire as the one we repaired was the same colour? Maybe I'm wrong.. Anywho.. The end of this wire is open metal... So dunno what would be going on if it "touches" the body work.. So I'll be taping that end up.. I now know where to find it if anything else comes of it..

    Now.. ANOTHER problem...

    Just above where you find the sparkplug there is a round ball thingy with a little hose that runs down and attaches to this big metal thing..?? (yah know where I'm at eh??) I think I knocked it off while I was fiddling round..
    Anyway the thing thats on the end of the hose that you attach to that big metal thing is ABSOLUTELY fulla crap.. And looks blocked as... What is that hose for and how would I go about cleaning that gunk out of it? eg what should I use.. I'm sure because its meant to be attached that its something fairly important..

    Perhaps you need to post pics?
    Do you realise how many holes there could be if people would just take the time to take the dirt out of them?

    Well those two sparkplugs are the same size, so perhaps you can use either. I've seen people use both D7EA and DR8ES plugs in my bike. The letter is the size of the plug, the number in the heat rating, and the other letters I don't know. So maybe you can use either but it's probably best to find out what the manufacturer specifies.

    I too have a stray wire... it's black, open metal on the end, and is up around my headlight. Always wondered what it's for; can't find it on the wiring diagram (not that I looked really hard, it's a maze), and having it there doesn't seem to cause any mysterious electrical failures.

    Round ball thingie. You don't mean the sparkplug cap? Or maybe it's some mysterious oiling setup that two strokes have? If nobody can work out what you're talking about maybe some pictures are in order, lol

    Good luck. Sweating over a kickstater is not fun, I know how you feel.

    Sorry mate - they are utterly different. Yes, the threads are the same, but the length etc are nothing like

    Sorry, I meant the plug width.

    Are you talking about Kittie's plugs, or my plugs? Mine are the same.

    EDIT: I had a look on this page: http://www.kaila.net/tl125/tl125ngkcode.html . Kittie's plugs ought to be the same size, just that one is a resistor type plug and booster gap or something. Thread reach and thread diameter are identical.

    Yours. I've been looking for pics, but I will guarantee the two are not the same.

    So some simple diagnostics, replace the plug with the old one and see if that fixes it. Interesting that one is B and the other a BR though.

    This one is IX = Iridium = should be the better plug. Perhaps just the wrong rating for that engine?

    Going by the codes they too have the same width and reach. I've got one of each in the garage... *runs out and takes a look* yep, they're the same size. Any differences are in the sub-millimetre range.

    How do they compare in the 'exposure' of the the electrode(s)? Sub-millimetre may be all it takes to be right/wrong.

    The electrodes look identical to me, and that's with the same gap, so they're bent on the same angle. Going by those codes there is probably a difference in the electrode; D7EA and DR8ES, the A and the S are important to the electrode. A=`Special design (no details given)' and S=Standard 2.6mm electrode. I don't doubt there's a difference, but using one is not going to make the piston smack into it and seize your engine. At least in my case.

    Okay... I dashed off into town quickly.. And ran into an old friend of dads who has just come back to the house to help me...

    The old plug that was in there when i purchased the bike is different to the plug that Maunders told me to use (I rung them this morning)... With the old plug, I was kicking and kicking and kicking and my bike just WOULDN'T START... 30 kicks utter exhaustion and I'd be lucky if she'd go.. (battery is fine)

    The old plug I managed to take out using my hand to just unscrew it (have been told it wasn't in there properly so I would have been losing compression?? Can anyone confirm if thats true or not..??

    New plug is in there now.. Did it myself.. Rusty checked it over and tightened it properly.. Cleaned my air filter.. Found the home for the loose wire.. It had a little clip thing that goes onto this little knobby bit near where the sparkplug is found.. (isn't the sparkplug cover, I should know cause I took this off myself) He mentioned it was for the... Umm whats that thing that heats up when you turn your ignition on? (forgot what he said)

    Found the home also for that piece of hose that was fulla muck.. Haven't cleaned it out though.. Will see if I can borrow a digital to get a decent picture of it.. Have tried before with my phone and the photo isn't clear enough..

    I was on the right track with everything.. So I'm proud.. Kinda.. Just panic'd a bit when I found a wire and I didn't know what it was for cause it wasn't attached to anything..

    Oh.. And bike starts 2nd kick with the new sparkplug we put in it..

    The plug that was in it when I purchased the bike, I have been barely able to start my bike with it in there.. Hence I rung up to find out what sort of plug should be in it (got warned it could of had the wrong one in there) New plug that Maunders told me to use, bike now starts fine.. (hope that helps)
