You need to think about how you ride the bike.
How many miles are on the engine? My answer will change significantly based on this answer...
Each modification can bring benefit, but in some cases cons too. If this were a commuter bike you'd get a different answer than if it's ridden hard.
Most big bore kits generate extra heat, and require higher octane fuel (more expensive). If you commute in hotter temperatures I'd tell you to steer clear of a 10.25:1 piston kit.
If you plan on just riding on the weekends and having some fun, the big-bore kit is good. I'd probably start with HD cylinder studs and the piston kit. You then have the option in the future to rework the head - either porting it, or just dropping some mild street cams in.
If you are tearing the engine down completely, I would start with the fundamentals - a new Tsubaki cam chain and HD studs - possibly new idler sprockets, cam chain guide, etc. They are more important than the big-bore kit.
What's up with people saying Tsubaki "heavy duty" cam chain?
Isn't that new soobaaky just the same chain that's already in there? And if they do stretch then what's ta keep the new one from stretching? I'ts just that everyone says replace chain replace chain, I'm wondering if they really know why or if it's another mooo thing. One cow turns right ohter cows come too. And I'm that funky looking cow that noone will play with. :woohoo:

Ok here's another one for you guys to argue about :laugh:
While I've got my 78 KZ1000 apart, I may just decide to splurge and buy ONE internal engine hop up item with my tax refund.
What do you think is the most cost effective? The most bang for the buck? Cams? Pistons? Porting? I can only pick ONE so don't give me a long list...
The bike has BS34s, Dyna ignition, and Sidewinder drag pipe. All else is stock.
The Dyna is the really basic model that's completely inside the right engine cover. The coils are stock. I've always been a bit skeptical that performance coils really do much, but feel free to tell my why I'm wrong.
So which ONE would you pick?
Smash the BS34's with a great big hammer and buy some real carbs :laugh: .....there, that ought to get a rise out of some people this morning :woohoo:
Bore it to 1075. Anything you add after that is icing on the cake [/quot
The rubber police are coming
They have a warrant for the hammer
Hurry! Hide inside a 29 youll be safe

not 435's plummen,geez! :silly:
cams matched to whatever you got.
hard to pick one thing because it all works together,but a set of upgraded cams even on a stock motor is noticeable.

Wow this one is popular! Thanks. It will be mostly a ride on the weekends type of bike. Sometimes pretty hot here in Sac, but I won't be sitting in stop and go traffic a lot. The ODO says 36,000 but who can say for sure if that's correct. I plan to do all the needed stuff to make it reliable as top priority, then perhaps the one mod as well.
Yes I think the cam chain, studs and rollers is a good idea.
