Spark plug removal
07/03/06 at 19:29:54

Have just done the spark plug door mod and it looks like the gas tank will still somewhat obstruct access to the plug. What is the drill here? Can you get to the plug with a straight plug wrench or do I need to use a universal (swivel type) joint and a 3/8 socket approach? Please advise. Thanks in advance.

Jack H.

P.S. What is the wrench size for the NGK plug?
Thanks again

JH

You have to use the original plug tool. I first slide the tool upward under the gas tank until I have enough clearance to manuver the tool toward the spark plug and then slide the tool down toward the plug. Even though I remove the plug several times before, I still have to play around with this technique to get the plug tool on the plug. It's a try and try again game, so be patient. You will find the right spot that will allow you to get that tool on that plug. Good luck.

Posts: 173 Heathrow, FL Gender:	Re: Spark plug removal Reply #6 - 08/14/06 at 05:39:07 I cut about 1 inch off the stock plug wrench. This lets me slide the plug wrench down over the plug quite easily and still leaves enough plug wrench shaft so I can use a 17mm stubby open wrench to start the plug. After that the plug wrench will spinn by hand.

Must be some sort of sick joke that the good people at NGK played, knowing that virtually no tool set in the world comes with an 18mm socket or spanner. This had me pulling hair out for ages!

Posts: 2041 Cumbria,England Gender:	Re: Spark plug removal Reply #8 - 08/16/06 at 03:36:55 Just a thought, When you have your plug out why not replace it with an iridium from NGK (DPR8EIX-9) or Denso (IX24B). If You are going out in very hot weather or use prolonged full throttle then perhaps a DPR9EIX-9 or IX27B. Clive W

What is the difference between the two types? I mean, I did a small amount of reading and it looked to me like the difference between a DPR8EIX-9 and a DPR9EIX-9 was that the former has a threaded contact.

The second 9 is just the gap in 1/10'ths of a mm (as supplied). the first 9 is the heat range, higher number for higher operating temps. Clive W

As a side note, I don't have the suzuki plug tool. I do have the plug tool from my cb550 and it works with the plug door mod. I noticed home depot had some short plug wrneches in the lawn and garden department. they looked to be the right length but, I wondered about quailty.
