Fitting New Spark Plugs ?

[Old Nyk]

Got to know my 1984 ZN1300 Voyager a lot better now.BUT ! aint done this one yet .Thought i would ask advice "As Usual" !!.I am going to change the Spark Plugs.I know that the Petrol Tank has one bolt to hold it in place.Ahhhhhhhhhhhh but what happens after that ???.I also know that somewhere under there are Petrol Pipes and an Electrical connection for the Trip Computer so a bit of advice from you fol'ks who have already done this would be much appreciated ,probably being over cautious but have been caught out before.You know,when you gently pull somethin and bits and bobs go flying everywhere and you don't know where they come from ??.You work it out eventually but better to be prepared eh ! and happy Holidays to you all.

The screws a good place to start,but theres a lot more to go.
Make sure the fuel is off and drain the lines as best you can,cranking it it over a few times with the fuel off will work pretty good.
Disconnect hose at shut off and return lines ,plus the small vent line at the rear of tank.
Pull tank back a little so you can raise it up and reach under the right side. Disconnect 2 harnesses (one from the trip computer the other from the fuel gage) and the vent line from the fuel gage.
Remember,7 gallons of "petrol" is heavy ,so you want to take a longgg ride before you start.

Just a few additional items - pull the lower faring legs to make it a lot easier. Also if you have the California version of the bike you will have a few extra hoses to deal with, just make sure you install the hoses back in the same places as they were removed from. Take a few pictures and and use colored tape to keep track of the hoses.

Re: those two connectors under the tank - if they haven't been split in a long time they will want to stay together (read hard to split) so get someone to help you hold the tank up while you split the connectors and once split clean them up and grease with a silicone electrical grease to preserve the connectors and make it easier next time.

Since a full tank is quite heavy you may want to drain the majority of petrol from the tank. Muscling a full tank will make it easier to put a dent in the tank so a near empty tank will keep you from damaging it.

Thank you for that info,i new it would be a tricky operation so looked to the experts on here,your time is really appreciated.As for the fuel i don't keep too much in there while the bike is laid up.I will feel a bit more confident after your advice.Thank you,regards.Old Nyk.

Well Blimey ! after all that fuss i made Took another look at the situation and changed them plugs without taking the fuel tank off just needed a double knuckle adapter on a plug socket .The plugs were black as coal,bike runs better with new ones.

I have always taken the tank off to get to those middle 2 until only a couple weeks ago.
I ran across an old double knuckle with a T handle and said "what the heck ,lets try it"
I was actually a little surprised when it dropped right in and worked perfectly.
I'll never have to pull the tank for a plug again.
