Loud poping noise in engine

[irishluck]

If you are at TDC on the compression stroke, the lobes should point up, away from the piston.  Sounds to me like you're on the exhaust stroke.....  And you are correct in cyl numbering, left-most cyl is #1. 

okay yea i guess i did it backwards so now the lobes are pointing outwards, mine don't point up though and the book says that that are suppose to point outwards, not up.

Also someone mentioned that the coils are suppose to be that the first one is 1-4 and the 2nd coil is 2-3.
Well my coils are that the first one is 1-2 and the 2nd one is 3-4.

And before i was having these problems taking it all part and what not the bike ran just fine, i mean i rode it for a couple of days just fine.

****Well, my coils are that the first one is 1-2 and the 2nd one is 3-4.****

There is at least one of you problems right there.  I doubt the bike would run at all wired this way, and in fact, may well make 'loud poping noises in the engine' when you try to run it.  [1-4 / 2-3] is correct. [1-2 / 3-4] is decidedly incorrect.

My god a real racer, he can create his own firring order. Guys that's what we've been doing wrong all these years.

[Pat Conlon]

He has a crossplane crank....

That's right I forgot the RACERS got the crossplane  

And that also explanes the fuel system that he has.

Listen to Dan. The firing order on the FJ motor is 1-2-4-3. Sitting on the bike, looking down, the left hand coil goes to cylinders 1 and 4; the right hand coil goes to cylinders 2 and 3.......Unless you have the crossplane crank motor.

I heard that with my bad ear.

[irishluck]

well then I have a cross plane motor or what ever,  cause my coils are set up as 1 and 2 for the left and the right one is 3 and 4 and it ran perfectly fine before I tore it apart, I rode it for a week with no problems, no gas problems no popping problems nothing.

Hooked it all back up how it was when tore apart, started just fine, but after couple minutes shut off, switched plug wires, tried to start and it popped and now wont start.


and now the even weirder thing about it is when i crank it over now, there is no popping noise or nothing

So what exactly is a crossplane motor

[Marsh White]

No you don't.  You are just confused, ignorant and arrogant.  Why do you continue to ask for advice when you won't take ANY of it?

look man I'm telling you my left coil is on cylinder 1 and 2 and my right on is on 3 and 4 and it ran perfectly fine, I know how cylinders fire. why the hell would i make that up. I'm trying to take back as much advice as I can get but when yea don't listen to how I know my bike is set-up then nothing gets accomplished here. Hell i can even plug the wires back up and start it and send you a picture and video, would that prove my point to yea that i know what I'm talking about

I reckon the engine is one tooth out on the camshaft.
I did this ONCE, and the bike ran but very strangely, but did actally run, luckily didn't valve versus piston interaction didn't occur.
Two teeth out on the cam and it's tit's up.

But i am beginning to think irishluck seems fullo'shit!

Come on son

[irishluck]

alright you all think what ya want, since im the irish guy full of shit and dont know jack
