We have done a dozen or so to this point and tested with stock cams. (over 200 std RWHP)
Now were going to test with bigger cams and see what its true potential is. The zx14 cams are holding the engine back. At that point we will reevaluate the ports and make any needed changes to match the bigger cams.
Its a constant ongoing proccess that never really ends as different bore/strokes and cam grinds are tested.
We are looking at cam and port designs for the 1530/1587 combos now. Thats the cc range where a better port design will be mandatory to make use of big cams and make big power numbers.
It just seems that many people are shying away from boring the zx14. I guess due to the added cost of disassembly to bore and replate. Kawi made a huge mistake making the block part of the crankcase. They just dont care about anything after the bike leaves the dealership I guess. I think that factor alone will sway many people to the busa who are on the fence at the time of purchase. Such a shame, its a huge marketing mistake.
Anyway, I'd recomend bigger cams with the ported head. They complement each other and bigger cams are much needed. I'll be posting some results with bigger cams coming up.
Muzzys has billet cams for the zx14.
Or call WebCams, they will weld your cams.
Megacycle flat out refused to weld zx14 cams for us or anyone else!!! They will ONLY do billet zx14 cams. They claim they are too thin and warp badly and need to be straighened. But most hard weld faced cams warp and need straightening anyway so.....???
Trust what Megacycle tells you. They've been in the game a long while. Remember, only a farmer can start with shit and end up with something good.

Don't know larryc. All I heard was that the cams didn't produce any real gains on the dyno in a stock displacement motor. I don't think Brian is running a racing program with the ZX-14 like Brock did. He races a Hyabusa personally and most of his business is Suzucki based. I think I remember Brian telling me one customers bike that had the head/stock displacement/stock cams combination ran 154 quarters with stock wheelbase. Don't know what the et was. The drive in drive out ZX-14 combo was a very mild state of tune with just a milled/ported head and re degreed cams. I would bet most of the ZX-14's he did these packages for were stock lenght street bikes that are not raced regularly and the owners were looking for a inexpensive, reliable bump in power.

Call Brian at Quantum, I am sure he will share the results of testing with the cams he has tried. He has built and dyno tuned ZX-14 motors with cams in both stock displacement and overbored versions. I believe he used Carpenters cams on the first overbore motor. Not sure whose cams (Web or Megacycle) he used in the stock displacement bike. He has also tried at least three head porting services. Brian is a real straight up guy with no favors for any particular supplier. He just likes to use what has worked for him. Brock taught him well and he reminds me of a younger version of Brock.

Thank you for the update. Much appreciated. I've been to busy with the old school stuff to look at the 14 developments in a while now. Glad you guys are keeping things driving forward.
It appears even Rob Muzzy is hard pressed to get his goals accomplished but is working hard to make good things happen. I'm sure they will in time.
Yes, I have had some email conversations with Brian quite a while back and some other forum discussions. I like him and his approach to performance. Nice guy. I hope he does well with his business. He's giving you guys honest information on his head work. Straight up with information that most places won't give out if you twist their arm. Support him as much as you can.
