Necessary to change plugs at 1200???

Coming up on 12K on my 05LT and wonder if it's really necessary to change the plugs. The wrench turner at local dealer says yes, but the counter guy said he has 24K on his.

Changed mine at 29,000, the new ones didn't look any better than the old ones. I will not be doing it again in 12,000. I think 12,000 is old school & went out with leaded gas.

I did

I changed them at 12,000 and now again at 24,000. Easy to do and is recommended in the Clymer Manual I use.

It gives you a quick check on how your engine is doing on each cylinder by looking at the plugs when changed.

Just my .02!

Bought used K1200LT number 3. This one is green/teal with 31,369(now 7/29/2018 54,143) miles and is an '02. The first 2 bikes made it to near 150,000 miles.

Due to heart health, the Dr says not to ride under 40 degree air temp. Ugh! Now it is harder to get my 18000 miles a year in just in the summer. Guess that stopped my 20 degree rides now.

if it's running good and the plugs look good why not just put them back in the engine? after all, new plugs are sometimes bad but very rare. omurphy

You boys know what to look for in a set of plugs besides soot and other residue? Look at the electrodes and make sure they are nice and square and have no rounded corners. The edges wear by sacrificing a little bit of metal every time it sparks. No one said these bikes were cheap to maintain. Start cutting corners and the rest of motor will wear sooner trying to make up were it's lacking else where....

Don't know if it is necessary. But, it's FUN!

Just be sure to get 4--force of habit, I ordered two and two valve cover gaskets; needed a new socket for the new plugs.

I will change mine at 12k intervals. There was a noticeable difference in the idle and feel of the engine after doing that on my '05.

I did for the first few sets, and could always notice a little improvement in the way the bike ran, but not something earth shaking.

I started running Platinum tipped plugs, and those can go 50K plus with no problems. I used Splitfire TP416D, but there are other platinum and iridium tipped plugs available. I liked the Splitfire because they had platinum points on both positive and negative electrodes, not like some that only put platinum on the positive center electrode. That one erodes the most, but when you are going for long mileage the un-tipped negative electrode will erode if it does not have platinum tips.

I don't want to achieve immortality through my work...I want to achieve it through not dying.

Last night leaving the office my bike started running so badly I didn't think I would make it home. Felt like it was missing on 1-2 cylinders. No power and stop and go traffic was worse than usual. I got home and changed the plugs. Now runs great. I was using the Splitfire TP416D recommended earlier. They had been in for 33,000 miles. Think I'll go back to the 12k recommendation.

Save your money!

For the 1st 45k I replaced the plugs as recommended, but noticed that there was no significant wear or deposits on the plugs, so I decided to experiment with extending the interval. On most modern engines with the high output ignition systems there is no reason the plugs can't safely go at least 30k, even 60k. It now has 137k, the oil gets changed every 5k (easy math) valves check every 12-15k (haven't had to change one in years) & the plugs & fuel filter every 30k. There has NEVER been any change in the performance or fuel mileage.

I run mine till I start to notice a slight dropin performance and idle quality. For my bike that was usually between 14-18k. I also flip back and forth between the iridium and splitfire plugs. I think I like the splitfires better though.
