how often should you change the plugs in your bike ? what are some other tune-up needs of a f4i ? and how often should they each be done? just hit 10000 seeing what she might need thanks in advance

 

Well if you havent changed them yet then I would change them now.
They dont need to be changed all that often, If you run high grade gas through it than they should last a while.

As for the other stuff, Think of it like a car. What all would you change on your car at certain intervals.

 

10K isn't time, but you'll want to check the gap on them.
i think the book calls for 16K...but i got like 12 out of mines...and they were still in spec...i just changed them cause i wanted to.

 

noob question - is it hard to change them? pricing?

 

Im pretty sure you take off the tank and air filter housing.
Everything above the top of the engine leading to the plugs

 

Ok I'm a learner here and don't know much about mechanics. We're talking about spark plugs right? How many are there? And why do they need to be changed? I mean if the bike starts, that means they're working right?

 

oh oh... on a car i change my spark plugs every 3500 miles ... on my bike i do every 5

 

every 5 is way overkill mang...manual says like 14K...mine were still good at 8K.
you just need to remove the fairings and drop (not remove completely), unbuckle the radiator and you should have enough room. is it easy to do? it's a PITA.

 

Like Tahoe said, need to remove fairings and radiator. Not real hard. More time consuming than anything. I think 4 NGK iridiums cost me like $42 from Advanced Auto. I checked mine at 8,000 mi and they were still good, but I decided to replace them while I had the fairings and radiator off. I think the book calls for checking them around 7,500 and replacing around 12,000.

 

yea mang...if you go through the trouble of checking them, might as well replace them!
