changing plugs
« on: July 25, 2007, 08:23:30 AM »
anyone can give me some info. to help along my process of changing spark plugs and wires...my grandfather was going to help me on sunday but I would just rather get it done on friday when I have off. I am hearing there is a tool in the tool kit to help you take the plugs out. I never gaped plugs before so if anybody has a couple mins. to explain this process to me I would greatly appreciate it....thanks ahead of time......NOOBY VON NUBENSTIEN.

Use either a feeler gauge or a plug gapping tool. You can get those tools at any autoparts store. Check your manual for the gap distance.

You should wait until your grandfather helps you on Sunday. Grandpas like that sort of thing. Also, if you don't wait for him, he might think you don't love him. You love your grandpa don't you??   ;)

Assuming you have the on-board toolkit, yes, it looks like a long wrench socket..kind of cheap looking ;), but it is a good fit for the inboard plugs which can be hard to reach.

Being a grandpa,  I vote for waiting too. We love doing things with our grandsons. :)

I vote for grandpa too. Spark plugs shouldn't take long. You can probably do those and the handlebars in an hour.

If it's a poll thread, I vote for waiting for grandpa.

If you want to make him feel extra special, change the plugs on friday. Then wait for him to fix your mess on sunday  :D

If you don't have the plug wrench from the underseat tool kit, this thread has a picture of one that is similar.

I use an 18mm plug socket with an extension that I picked up from NAPA a while back.

can i just buy the wires at an auto parts store any information that would help the wires would be great to....like I said noobie at chainging plugs and wires on a bike. I have the cb650 clymer manual but not sure how indepth they go into it in there and I am not at home so figured any help from the sohc posse would be awesome.

If you have Honda stock coils, then the wires are molded right into the coil casing.  There is an article in the FAQ on how to crack into the case and change them out, but it's alot of work.

What is your complaint about the wires?  Are you just wanting to change them because you are used to doing that when tuning a car?

You may not need to change your wires.  Pull the plug caps off the wires and look inside. If you see green, then clean the inside of the plug cap and snip off about a quarter inch of the wire.  Check the resistance of your plug caps if you have an ohm meter.  They should all be close to the same value and in the 5000 to 10,000 ohm range.  Screw the cap and wire back together.

yes, just maintain them.  They only require replacement if the coil should fail of if the wires get worn thru because of accident or rubbing. 

Clip out any green patina on the ends and keep the plug caps and cap seals in place so they stay clean.  Repeated snippings will of course shorten the wires, so be judicious and clip only when absolutely needed.

As a GHOF, I definately vote for 'wait for Grandpa'.  Moments like that are too precious to be traded for expediency.  I so often wish I had my dad around to help me now, even when I can do it myself.  Similarly, I bought a Triumph project bike from an even older GHOF.  When my wife suggested I'd get more done if I brought the bike home and worked in our garage, I pointed out how I think this old gent enjoys getting his old bike back on the road even more than me.

In summation, wait for grandpa.   ;D

I'm voting to wait for Grandpa.  Besides, wasn't it his bike in the first place?  Or am I confusing you with another member?

changing plugs:

Easy enough that anyone can do it.

Bonding with family:

Rare and and not everyone has the chance.


I wish my old man could help me out and I damn sure would take my time if he could. I bought him a project bike (as he had bikes when he was younger), but he wasn't up for it physically or mentally. I did learn & put together that 69 cb350, but I would still be taking my time on it if he were helping and not pissed that it hadn't ever moved.

I know you've been getting a loaded response to a simple question, but damn if reading stuff like this makes me pause- if only for a second- and think about what life is really all about.

On the 650's the plug wire are replacable. Ask for 4mm wire.
