You should get new ones or the seals can be damaged.

I have to take the fork off to change the seals right? Well the coils are firing so why change them?
I mean boots

Well I've never changed spark wires on anything ever I didn't know the wire boot was separate either. Idk what to do about that. Therez lots of different wires on the internet I'm not sure what I'm looking for. I'd need to troubleshoot the spark wires first

Gone threw 3 sets ....from Z-1 and Ebay....1st set from Andrews were white, yellow and now back to standard black.
Do u have links to these parts?

It is not a terribly complicated or expensive procedure, and it may help your present difficulties, though I doubt if this is the only problem. It may also save you money later.

Yes maybe but it's not like I'm never going to do it probably later this yr or next spring. What symptoms would I be experiencing if they needed adjusting? I mean I do hear the cams hitting the buckets a little but I think that's normal.

TexasKZ wrote: Typically, the gap gets smaller, sometimes less than zero. When the lash gets near or to zero cold, the cam can actually hold the valve open slightly when it is supposed to be closed. Under these conditions, the performance of the engine will slowly deteriorate, ultimately to a point at which it will not run. Often, valves and seats get burned, which can be expensive to fix.

0 as in the opposite of the lobe actually touching the bucket when it's not supposed to? Is that what I'm understanding?

I used to check mine around every 4,000 to 6,000 miles.... seems like a short time but these are NOT cars.
However, did I miss something here or did you say you have what amounts to you either having no interest/willingness or desire to do the cam lobe/shim measurements? Or is it simply, just no experience and fear of the unknown,
Why? Because none of us here ever did it before the first time either!!!
And, after I did it once, I was quite amused to hear my friends say they were taking their bikes "in" to have it done!!
LOL
It turns out, the actual act of measuring is the stupidest easiest part!
The tricky part is slightly holding the valve open with a $10.00 gadget on the edge of the bucket, wedged in between it and the camshaft, while slipping the shim out with a pair of tweezers.
The maddening part to me has always been buying, ordering and waiting for the shims needed to replace the ones that are a tiny bit too thick now.... etc.
I can't speak for others but I've don't think I've ever had to replace a shim that was anymore then one or two sizes thinner then the number on the shim I pulled out..... unless the head had recently had new valves installed and or a valve grind job.
But you might not even know that so.... get a factory manual and read all about it. You'll quickly discover how simple checking lash is... then if you need more help... you are in the right place.

See the following links:
Dyna black 7mm copper core from Z1E
Dyna red 7mm copper core from Z1E
The spark plug wire exterior insulation deteriorates over time and becomes cracked and brittle, allowing leakage of high tension voltage, and moisture intrusion.
The Dyna spark plug wires come already equipped with built-in caps (aka boots or covers).
They are intended for fitment to ignition coils that accept removable plug wires (not coils with permanently built-in plug wires aka integrated plug wires).
Am guessing that the bike at hand has plug wires that are detachable from the coils, so that new plug wires may be fitted to the existing coils.
Good Fortune!
