Loud poping noise in engine

[irishluck]

so i guess i put the spark wires on backward on cylinder 3 and 4 of my 87 fj1200

went to turn it over, heard bigging popping noise, and now it wont start, cranbks but no start.

My guess is it snapped a cam shaft or jumped timing, anyone give me any advice?

[irishluck]

heard big popping noise***

[andyb]

If there's no nasty noises when turning it over, start with a compression test.

If that is flunked, pull the valve cover and start lookin for issues.

[irishluck]

ya not gona do a compression test cause it pops

i really think i just threw the timing.

[andyb]

Possibly, take it apart and look.

[irishluck]

well i did take the head cover off and when we looked at it we couldn't tell much difference but think i jumped one tooth.  How do i possible turn the crank to line the cams up to make sure there timed?

[andyb]

Degree wheel, pointer, positive stop.  Or line up the marks and see where they're at.  Didn't you just have this thing apart?

You'll have to pull the cams to realign things.

[irishluck]

oh  no the engine, i mean i pulled the engine out yes to clean and paint the outside and to reaplce wheel bearing and uh paint the frame and such too, never dissasembled the engine... but now i guess i do ha.

so as fasr as i know ill have to loosen the chain which is the one thing idk how to do, then just line the cams up and put the chain back on right?

i guess in lamest terms

[andyb]

Get a service manual, and make your life a zillionty times easier.  That'll show where the timing marks are and explain how to do things in a much easier format.

[irishluck]

oh i got one, i just thought someone could explain it a little better and a easier way to do it, and i dont mean by cutting corners, i mean by just explaing it easier than the book can

Irish,

You would be very well served by taking a course in basic automotive servicing.  One that starts with how to change a tire and goes from there.
All the manuals for the FJ presume a basic knowledge of maintenance procedures which you seem to lack.
Knowing that you want to have your bike available to ride this season, I think your best bet is to take it to a dealer.
Sorry to make this suggestion, but it might be the best way.

Best of luck,
Arnie

well let me ask this question, I know everything about cars and repair. I can rebuild a car in 6 months. My last one i rebuilt was a 1973 dodge charger. I can do anything with mechanics, my deal is I guess are they the same as bikes?

I guess i should have asked this question in the first place=/

But I just have no idea how bike engines are and what not, I mean I understand that there the same concept, but I'm pretty sure there is many differences from a car and bike.

I sometimes wonder if you are actually Klavdy or someone else just trolling here...but sadly that is not the case.  Apparently you are real.
