bike no go. help

[poorbastard]

Just having gone on a ride in Wellington with other KB members my bike was loosing power at higher speeds (not that we were speeding at all). Anyway got home and decided id pull the plugs out and give them a clean since I hadn't done it since I owned the bike. Pulled them out and noticed there were numbers on the plug socket thngs 1 to 4 except 2 and 3 were wrong way around didnt know if they were in usage but the numbers on them were anyway. So swaped them over to see if bike ran better, I put the plugs back in and started bike. Backfire and running like shit I swap them back. Bike went for a little bit but not running all cylinders and went like shit. Now it has stoped and wont go at all. Spark plugs all create a spark and all conections are working.

What the F%#& have I done and how can i fix it. Any ideas what could be wrong?

maybe you put 1 and four back wrong possibley as well if they r the wrong way round still that would explain it maybe?

Na 1 and 4 cant b put in any other ways they wont reach. Thanks anyway

What firing order do you have the plugs in ? Sounds like you've messed it up.

Do the spark plugs them selves have an order in which they have to go back in? The plugs/cables are back where they were now.

I can come look tomorrow if u want. got same bike and am now an "expert" on coils etc for them :D PM me and let me know.

plugs can be put in in any order it's just the leads you need to get right.

[crazylittleshit]

It sounds like you've got a bit of carbon build up.

I have no idea. Went out and replaced the spark plugs today see if it made any difference. There is still compresion but just not firing, as iff gass not geting to engine or sumthn.

Swapping the leads was not a great plan but when you put it back all should be fine again... I wonder, do you know how to clean your plugs?

There are cheap sand papers out there that have a waxy texture... see what you've got, get good paper or use a wire brush.
When you cleaned them did you clean the crap out from inside (or under) the contact thingy?
Did you set the gaps correctly... one of the guys posting might have the correct gap, hacksaw blade should get it running.

I might be barking up the wrong tree... but a possible cause anyway :yes:

yip plugs were cleaned with wire brush and sandpaper but has new plugs in it now anyway but still doesnt go.

[FROSTY]

sounds to me like ya fouled the plugs. That said it could be that whatever was going wrongearlier wasnt fixed by cleaning the plugs -it may have decided nows the time to crap out.

[DingDong]

if your sure the firing order is right and that all plugs are sparking it might be fuel... do you have a fuel pump? the pump may have been shot before you cleaned the plugs and is the reason for your lack of power at high revs ...

The plugs all hav current going through them when tested. Doesnt have a fuel pump I dont think. Gravety fed im thinking I may be wrong but cant see one anyway. Yea the plugs are in the right order well im prety sure. May be a bike shop soon.

PM groomer, he'll sort it pretty quick I'm sure.

get a BIG hammer, long handled one is better,

stand back with safty glasses, and whack the demons away.. aim for engine...:devil2:

When you pulled the plugs out, did you take off the tank? cos it sounds to me like it aint getting gas, (ran like shit, missing, and now it wont go.) Whack the tank back off, and check the vacume hose is where it should be.

Don't tempt me im geting frigin close to seeing how it will withstand my car rolling down the hill towards it which also isnt bloody well going :mad:

I know this isn't hugely inciteful but I reckon try swapping the leads around again. When I was doing mine a while back I forgot the order and had "issues" trying to sort it out - had all the symptoms that yours sounds like it has. I was sure that I'd put all the leads back on the right ones but it turned out I hadn't. So yeah - I reckon try again. Boring advice but it might save ripping out hair and chucking more $ at a bike shop.

Cheers Ill try again tomorrow. Think Groomer is going to come and have a look at it for me hopefully he will know what the hell is wrong with it if its not goin by then.

I fixed it from the comfort of my desk at work :)
haha. All sorted..had leads on wrong.

Yep - sounds like the lesser-spotted lead swapping gremlin has reared its head again. It switches them over when you're not looking, so you think that you've already tried every possible combination. At least you outwitted it though and there's nothing wrong with the bike!

Yeah lucky I wasn't there in person, or I woulda given that gremlin a fair beating! :)

Thanks heaps Groomer. Im riding again :ride: . I'll rember to label things next time.

Gremlin......... Yea thats right it was the gremlins fault not mine :whistle:

Bloody gremlins I oughta teach them a thing or two.

glad to hear it all good :yes: groomer... your a nice guy :Punk:

Isn't the firing order on all inline 4's 1-3-4-2? Anyway, most in-line motorcycles seem to use the 'wasted spark' technique when firing, which renders the firing order pointless. It goes 1&4 then 2&3 and back to 1&4 etc. Saves money on coils - cylinders 1&4 fire at the same time, every crank rotation, as do 2&3. So swapping the leads for 2&3 shouldn't have any effect.

I hope you could get the gist of that...

Almost all inline fours use 1342. Except the ford E93A which just HAD to be different and use 1243.

But the "spark on every TDC" is not so universal. And if it isn't you still need to be sure that the spark is occuring on the compression stroke and not the exhaust stroke.

Marking the leads is always a good idea. I use those little plastic tags that they use to seal bread bags. Free, indestructable and simple.

Correct, but Mr. poorbastard had them 1&3, 2&4. There lies the problem.
LH coil fires 1&4 at the same time, and RH coil fires 2&3.

Good points,though it's less confusing for the less knowledgable to say the plugs spark in pairs 1&4 2&3 One of each pair of cylinders being on its exhaust stroke,i.e. the " wasted spark" :2thumbsup
