Welcome to KZr Jeff.
You sound like you have similar interests (besides the KZ) to me....into rock-crawling my truck, and I'm a HUGE Mopar fanatic (Chevy & Ford suck....watch the backlash I get from this statement!
)
Seing as how you said you plan on changing a few things on your bike (the header, brakes, etc.) do yourself a favor and hold on to the old parts if you have the room to do so.
KZ parts are similar to some Mopar parts, they're like gold to the right person!
Besides, they can really come in handy down the line:
1) Returning the bike to it's original state if you choose to sell it (an original bike is almost always worth more than an altered bike).
1A) Most parts for our KZ's are no longer manufactured, so spares or replacements can be almost impossible to come by sometimes and can be very costly!
2) You can always list the swapped parts on eBay or in the classifieds here to finance another project/for "mad money" that the missus doesn't need to know about.
.
3) Those swapped parts can be used to barter with other members here who just might have that long sought after part YOU need/want.
Oh, when you get a chance I'd suggest listing your bike model and year as well as your location in your profile.
It beats constantly repeating what bike you have with any tech questions you might have, and you never know what other KZr member might be near you to lend a helping hand or to go riding with.
Have fun!
