1347 back from Muzzys
Today, I met up with Rob Muzzy and went out to the shop to pick up the bike. Integral with that was a test ride so they could get some feedback from me regarding the bike's rideability after their mapping of the EMS system. I was given a good route to follow, that incorporated several different types of road so that I could test the bike out under varying conditions. For those of you unfamiliar with the Engine Management System offered by Muzzys, here's the link:
http://www.muzzys.com/muzzysECU/index.html
The bike started promptly with the choke applied, and settled into a smooth fast idle of about 2k rpm. Once it was warmed up a bit, I left on the route. The first half hour was spent feeling the bike out and judging just how much throttle to use under different circumstances. Compared to a stock bike, the throttle response is incredibly linear. It truly feels like dialing up a rheostat on a nuclear reactor. That goes both ways, tho, and a steady throttle hand is required to shift smoothly. If done right, the engine will not drop 100 rpms between shifts.
I tested part throttle response, linearity under increasing and decreasing throttle, and checked for any surging under part and full throttle conditions. None noted.
Next, I let the bike heat up till the fans kicked in, then repeated the test. The bike started and ran smoothly when hot, and no stumbles or hiccups were experienced. It still pulled strong up to redline, so wasn't going lean on me, even with the motor hot. This took about a half hour, as the air was fairly cool, and I had to troll along to get the motor hot again before conducting the next test.
The third part was accomplished when I stopped for gas. I let the bike cool down completely, then checked for any dragging of the starter, or hard starting condititons in general. None were experienced. This is the original starter on a 2000 bike, and it's never been hard to start with the EMS on. The same bike, with the stock ECU and a PCIIIR, would occasionally exhibit the starting probs many board members have posted, but never any probs with the EMS. The last part of this test was doing the above tests with the motor fairly cold. Once again, smooth response, very very very precise feel to the throttle, and it will reward you if you have great throttle control.
The last test was the most fun (and noisy) part. Here I am, on back roads in the country, and the bellow of the 1347 at full song, only slightly muted by a muzzy stainless exhaust, was causing *great* consternation among the various herbivores contained in the surrounding pastures. I got more mean looks from llamas, cattle, horses and sheep than I would have though possible. Basically, I ran the bike up to about 7-8k rpm and held it there, riding around in 1st and 2nd gear, only modulating the throttle a little bit, checking for any signs of ignition breakup or fueling probs at higher rpm. None noted. I then made my way back to the shop, where ZHooligan (who came down with his truck to ferry the bike back up to Washington) was waiting. I guess everyone was expecting me back a lot sooner!  But it was important to me to test the bike out as thoroughly as possible, under every circumstance I could think of and give any feedback to Rob before I took off with the bike.
I'm pretty damned happy with it. It met my goal of getting around some of the limitations of the stock ECU, and providing a single system that lets me integrate an air shifter, provide launch control, possible NOS triggering, and several other neat features.

oh yeah, but can it groom the dog?
sounds like a damn nice ride swft. glad to hear it all went so well. that's a damn unusual thing for a project so complex & unexplored to go so well. sounds like congrats to muzzs (i assume) are in order. now if only kawi had done so in the first place. maybe its time they made muzzys do the r&d on their new bikes?

I can't comment on the decision by Kawasaki to take their racing program in house. Of course, the record speaks for itself - Muzzy's Kawasaki Superbike Championships, vs. Kawasaki's In-House Superbike Championships.

It was fun and interesting. While Swft went off for a 2 hour test ride that had us driving the route looking in the ditches for him, I also got to chat and hang around with Rob as he showed me their facility various projects etc. They were doing abunch of testing on the Proton V5 engine. That was really cool to see and listen to. Muzzy is working on the engines longevity, power and torque curve etc. It sounds pretty damn cool. Definitely exotic. Carbon fiber valve covers even.
Rob showed me there Prostock engines and all kinds of cool things about it. I didn't realize that they have to run carbs according to the rules and that has been a challenge working out carburation and frankly carbs that work for the application.
Rob mentioned for you guys thinking 1361 that they are getting close to releasing a 1427 (my memory might be off by a cc or two). They have been successful with a larger bore and more stroke on some street and race applications they've tested. So they are getting ready to roll out the new kit. Bigger horsepower and bigger torque!
If you are ever in the Bend area it is worth taking a moment to visit Muzzys. Nice folks and to a person in the place they all love bikes. Makes a difference.
If you read this post, Thanks for your hospitality Mr. Muzzy!

You are saying that they are basically doing what SuperBikeMike did 2 years ago.........Yawn again!!!!!!!!!! Funny though when he did it, Muzzy was saying the biggest that was safe was a 3.x bore=1270 and a 4mm stroke. Anything bigger they said had to use an external starter. Everyone dogs out people until others COPY and give it approval!!! If anyone wants that kit, you can call SBM now and have it. WHY WAIT!!!!

How about us mere mortals ?
SWFT, Doug,
Would you recommend this system for those of us who continue to struggle w/PCiiir issues? When my 1361's temp gauge reaches 9 o'clock, my bike barely cranks. I got stuck in traffic today and my bike just flat out died. A couple of times it fired, and spewed black smoke before dying. After letting it cool down a bit, it fired up and ran like a champ. This is frustrating....! I don't know if I had a vapor lock, or what; I had just filled up, & had my fan switch on to keep the engine temp down. I don't know what to think. Over the past week, I did two loops around the Cascades. The weather was quite cold to say the least, but I didn't have one starting problem, go figure....

Hi Megabyte. I'll have to let Doug answer one that. I bought the EMS to address some specific limitations of the stock ignitions system. I can tell you that I think Muzzys has been very good at supporting the system, and that they've stepped up and invested time and energy into developing a complete 'package' to integrate it with the zx12r.

Hi gg,
I didn't ask for any horsepower numbers. It's not what I was interested in. Last time I checked, it was making almost 205hp/122 lb/ft of torque.

Yah, just a few cc's difference. I built it to be legal for the 1200-1350cc class at Bonneville, if I ever get a chance to go.

Just took some pics of the EMS / Air shifter:
They came up with some specific mounts to accomodate Dino's seat hinge. That required repositioning of the bottle, but actually makes it easer to disconnect the bottle for refilling.

Tried out the airshifter today. Works great. Never took the bike over half throttle (public road) but it was banging them off quite nicely! Very happy with the custom install (GP Shift)

SWFT,
You or Don should have brought your bikes to Cycle barn's Dyno Shootout. With the exception of my sick bike getting second place, the Suzukis ruled the day.

The turbo would have ruled anyway! Frankly I round tripped Bend on that Friday, slept in Saturday, prepped the quad and spent Sunday thrashing the kids butts in the woods!
And until MVR and Yosh get my EMS system worked out my bike is not going on the dyno again.

That's a good question. I think it's going to be the ZZR1200 at this point. Either that, or I put the stock bodywork back on the 1270.
