Has anyone out there done the Muzzy big bore kit yet? If so what kind of dyno numbers have you seen?

I am thinking very hard about it but won't do it unless the claims of 160+ rwhp are true. $4k is a lot of dough...

I am interested in drivability and final cost including jetting, pipe, labor, etc. Include model year too as the kit for 98&99 models is more costly to acquire.

Thanks ahead of time for the info.



There is strength in numbers - big RWHP numbers......

Sorry, I haven't heard anything about the big bore for the 9. I have heard mixed reviews on the big bore for the 7R's. For the ZX7 it seems you're better off going with a 9R motor.

Are you the same teamgreen from SBN?

No, I am not he - just a newbie on this site who bleeds Kawasaki Green.

I ride a red 98' ZX9R though - go figure...

There was at least one guy here who was going to do one - but his garage burned down. He got another bike - but I haven't heard anything about the kit yet.

It sucks not being able to search all the old posts anymore. That's a lot of good info gone/images/icons/frown.gif.

Yeah, I was trying to go back and find his handle to contact him but all that info. is gone.

Maybe I'll just go buy the new 12R instead..... No problem with HP there!

I have a friend who got a BB kit for his 9 and he sent it to muzzy's to get the work done and got some head work done too along with cams and stuff and he is getting(his words)around 200hp at the crank(Muzzy dynoed it for him)

The kit, labor plus ti pipe and jet kit with sales tax gets up around $3800.

I've been quoted around $2700 for just the big bore kit including labor.

Do it!! Do it!!

Oh wait, 12R... er, that would be an insane amount of power. If my calculations are correct, that would give the bike + rider right about twice the power per pound that my bike has. /images/icons/shocked.gif

Seriously, in your estimation, would it be possible to A. get that power to the ground without ridiculous wheelspin, B. get that power to the ground without ridiculous wheelies, and C. get that power to the ground without going through a rear tire every 200 miles?

I could go to LABusas or zx-12r.org, but I'm only curious. :eek:)

actually, if I do, it'll be the 1361cc big bore/stroker upgrade. Go all the way. That dynoes at about 205rwhp.

Of course I don't need this, its mostly sick fun.

Make sure you get the new swingarm and the 250-series tires at the same time. /images/icons/smile.gif

I've got the Muzzy 998 kit, Muzzy Full Ti w/Oval Ti can, Factory jet kit and Muzzy cam sprockets on my '98 ZX-9. I don't have dyno #'s yet but I will say it made a HUGE diffrence in seat in the pant's power. It's almost scary and I still get caught off by it once in awhile, accelleration is unbelievable and hits redline easily with my stock gearing.

If you want a dyno chart showing what the kit does on a '99 ZX-9R check here, they show it vs. just a pipe and jet kit.

I don't know what else they did besides the kit, pipe and jet kit, I've also degreed my cams per Muzzy specs.

Everything cost me about $2500, did all the work myself.

$4000 does sound steep. I put this out earlier (and no I don't work for them) but Carpenter Racing in Berlin NJ, does a drive in drive out kit for the ZX9. Around $1600 parts and labor for the Big Bore kit, another $1000 for the head work. Again this drive in, labor, tuned and then drive out for around $2700 give or take a hundred. I'm waiting to hear from some more people who received kits before I drop $2800 in the motor.

I have my 98 in the shop right now to get the muzzy kit put in. With a few other goodies like degreed cams, adjustable ignition advancer, jet kit, ported 2000 head, balanced crank and rods, K&N filter, and a Dyna 2000 ignition system. The ignition system was a last minute thing since the motor will not start with out the cam sensor that the 98 uses but the 2000 head does not. The bike should be done this week with a dyno run done too.

You need to have a full exhaust, degreed cam, ignition advancer, jet kit, and the muzzy kit to get close to the 160 hp they claim. I talked to muzzy before I started and this is what they had done to get the 160 hp out of the bike. I will post the results then I get the bike back.

This is great information guys, thanks. The dyno from Ivan's was extremely helpful - the first one I had seen with so many mod's listed for this bike.

I am in Colorado and don't think I'll be able to get the prices down as low as what others have - maybe around $3200 including pipe and jet kit. I definitely do not have the ability to do all the work myself.

I think I'll shop price a little bit for the labor. I already had one local shop butcher the valves in my 9R with a bad spec at the 6000 mile service. They said the technician had a "bad day". It took three weeks for them to make it right..... Anyway, I'll pay more to avoid that crap again.

I look forward to more dyno information as more of you guys get your kits installed.

I'm sure we all have stories of a shop that treated us or our bikes poorly. I have tried to let it go.

FYI, the local Kawasaki shop sucked at that time and I took it to the Yamaha / Suzuki dealer instead. They also scratched the SH*T out of the frame but they paid to have it repainted.

Oh well..... The bike still runs great at 11,000 mi. so no permanent damage was done.

to the guy who was gonna bore out the 12r....go for it dude, then gear it so that 1st gear is remotely usable...at that point you should be geared for 250 mph probably haha....with the nitrous you'll be able to take on john force. lol
