How about a spark plug thread
Written by alfr4d on 8/10/2012 at 09:19 pm

Wade, That is long for plugs, even with having two in each cylinder. The manual
recommends change on every 8.000 miles. Go for the longest lasting plugs =
80.000 miles for Iridium. The gap does not only stay the same but does not have
to be changed with a special tool before mounting either. For me, having no
mishaps with placing and removing plugs is the only requirement. Is it not very
deep, then it is the strange angle or the lack of space to work in and the
thin-wall tool that should hold the plug in and stay straight at it is
problematic. I have read about mechanics screwing the job up on this bike and
left the customer with oil leaks.

The history of the list mentions that the older architecture of the engine head
will benefit from special stronger sparking spark plugs like E3. Nowadays only
the special designed curved shapes count in getting stronger explosions. Some
people have actually measured a better millage and someone experienced more
power. These plugs have three contacts around their head and are supposed to be
a quality product. It is always nice to mount things that pay themselves back.
Better millage and more power means a better running engine but new plugs may do
that anyhow in some cases.

One user report:
>> If I may suggest, when I put in E3 plugs, it made a noticeable difference in
both mileage and power. The iridium ones did not. <<

Have a nice weekend, can feel it coming. Alfred

cars and trucks can sure go in bikes. This sure saves a lot of work of changing
plugs and the fine wire gives a better spark with much less chance of fouling
alonc with the gap doesn't change because of no tip errosion. The current
equivalant plug is the NGK Iridium, DPR7EIX-9,for the PC.

What do you use for spark plugs and how often to you replace them? I went with the stock ngk's when I got my PC. I've now put 30 or 40k on her and figure it is time to replace the plugs. (Have ran platinum in my cars so long I don't actua

        I got my replacement '94 pc with about 4,000 miles on it. First tune-up and new (iridium) spark plugs was at about 30,000 miles. Second tune up and new spark plugs was by Leland's excellent mechanic at over 65,000 miles. I noti

        I should comment myself, Iridium spark plugs may not be not the longest lasting. E3 guarantees their product for 100.000 miles or five year! http://www.e3sparkplugs.com/faq.php - first questi

    Thanks a lot everyone. This spark plug thread made me look in my records and I discovered that I haven't replaced my plugs in 36K miles. Now I've got more work to do. Ron Brown '89 Peace and Cuiet

    I installed iridium plugs about 30,000 miles back. No problems since installation. At time of installation I "thought" the idle increased by about 200 rpm after the install, and idle was smoother.
