Plugs are inexpensive. Just replace them.

Keep in mind, you will want to check valve clearance, etc. at the same time once you/dealer is on there.

 

yeah I plan on replacing them, it’s not the price!,
I’m on a time crunch with a trip coming up!
has Anyone ran them till 30k ?

 

I haven't ran them till 30k miles. Since you're in that far, just do it. (i think they would last longer)

 

I ran my 2015 to 24000. The plugs looked fine. The lash on the valve train was spot on still.

 

Youll start to get poor idle and small misses when they get very worn.

Id say they be grand

 

If one fails you have 3 other cylinders. Ever ridden a triumph? Sweet as!

 

I ran them to 100K + on my last bike. The ground electrode "red circle" was worn but plugs seemed to work fine. On my current bike I'm at 99857 miles on the same plugs. Have to do major service soon & will change them then.
All factory plug change intervals are optimistic. Untill there's a measurable difference in the ground electrode length I can't think of a reason why the plugs should be changed. Use anti seize paste on the plug threads when you do change them.

 

Thanks for the info! It’s very helpful.
that’s very impressive mileage “Sal R1.”

Always wondered why car spark plugs can go 60k and some 100k recommended interval replacement but not motorcycle’s, now much different can a car spark plug be?

 

A motorcycle engne runs at much higher RPM than an automobile engine. Motorcycle engines are also designed to run much harder (more power v. displacement).

 

Fixing to replace my spark plugs while doing other work, currently have headers off and have moved radiator out of way.
my question is
1) Can I access the spark plugs from the front since I have most everything removed, there is a panel that sits behind the radiator that once removed should give me access or appears to be that way ?
Before I go any deeper is it even possible from front angle by radiator?

it is not even close to possible to remove the plugs from the front of the engine. The air box must come off, to allow extension and plug socket, then removing the coils on plug require alot of room upward.
