timing!?
 

can anyone help me..... im about to trade an 84 ninja 900 for a 92 dsm and the owner says it all points to timing.... idk exaclty what is going on with it but he said he replaced the ecu and alternator so any help would be greatly appreciated on how to time it or what you all think it could be.. once i actually get it i will be posting up what all is wrong with it that i notice and try to get yalls advice

If the timing is off, its probably gonna need a cylinder head at the least. I'd do a compression test to see what condition the engine is in.

k so got the car and heres the news.... it turns over just fine gets spark backfires but doesnt start. spark on plugs is not consistent and is very irregular.... there are about 6-7 plugs that arent plugged in to anything and i dont know that they all need to be either though since there is no ac..... so i guess new questions gonna be, since theres spark backfiring and plugs unplugged; possibly a plug or two, clogged cat, or ????? causing the issue.... also the oil had quite a bit of gas in it, enough to ignite it on dipstick.... thanks in advance

Can you post pics of the connectors not plugged in? Also check to see if the fuel injectors are firing. These cars are know for jumping timing belts and ecu's leaking caps.

cant upload but can email them.... files are too big to upload... im certain the injectors are working because when i pull the plugs they smell like unfired gas. possibly clogged exhaust or what!?

I really doubt its a clogged cat, a car w/ a clogged cat would most likly start just lack power. If you want to email me pics shoot me a pm.

k... cant email cuz they are on my other computer..... but if it is the timing being off then what plug do i need to jump so i can actually attempt tuning it!?!?!?!?!?!?!?!?!? thanks

If the timing belt is off most likly the valves are bent. Try rotating the crank and if it locks up you'll know.

dude it turns freely and cranks with ease it just wont start..... the guy i got it from said the way to do it manually for the timing was to adjust the cps on the head while jumping a plug in the engine bay but he didnt know which one.... do you know which plug it is

Yeah I know what plug but the car has to be running to do that. That plug is to ground the ecu when your adjusting the cam angle sensor. It wont start the car.
