My bike runs great with my Akropovic pipe but I did notice some mild surging around 3 to 4K or so. Anyone else notice this? Ive got a PC3R that I havent installed yet that I hope will solve the problem. Have any of you guys had a dyno before and after with the pipe and then with the PC? What results.

</p>

Traditionally there is a bit of a spot around that point with the stock system that should improve with the pipe. However it may depend on your map, what map have you used? Have you tried checking out some of the maps on www.zx-12r.org in the performance >> fuel/timing mod section >> PCIII maps

Try them out and compare them to your present map and you may find some improvement. There is a mod that I have on my map that drastically reduced the on/off effect of the throttle, but it also made it run a bit rich, I am still in the process of leaning it out and finding a balance.

Maybe you misunderstood me. I said that I have a PC but I havent installed it yet and that with the pipe alone I notice some light surging. Is this normal with the Akrapovic pipe?

No idle problems just a slight surge at 4K rpms on the road. It feels like riding into a slight headwind type sensation. Anyway I was just curious if others ever detected this or it was just me.

Nope....Not just you!!!!



I installed the Akropovic exhaust and had the same issue. It did not feel really bad but at Highway speed, it would just kind of rock ya a hair back and forth. I did not have any idle hunt problems either!!!



I installed the PCIII with the map provided by Dyno Jet for the pipe and it did not solve this issue. I installed a copy of Harry's map that he had custom made for his bike...the surging stopped, I had a nice power curve and gained a couple ponies as well. All is good now.



I am not sure if easy has this map on his site, but when you install the PCIII and ya want to try out the map that I am using, just e-mail me at



[email protected]



I'll send it to ya!!!

ZX-12girl, can you email me the map and the description for what it is intended for.

I will post it on the site, after I put it in my PCIIIR of course.

Does it have the Cliff Randall mods for on/off response (modification of the 0,2,5% ranges?



Thanks,



Easyrider

I am not really sure Easy. I can e-mail it to you so that you can take a look. Harry has the same mods as I do. He took his bike to a fine tuner and had the map adjusted for max HP on his bike. He let me have a copy of his map.



At Deals Gap last year Harry and I put our bikes on the Dyno. We were the top two in HP out of about 10-12 bikes(ZX12R's). If I remember correctly Harry was at 181hp (Somewhere close to that) and I was at 179hp. The only differences in our bikes were that he had K&N filters and I did not.



I'll e-mail the list of mods that are on my bike when I send ya the map.

Hey ZX12Girl,



Please email a copy of that map when you get a chance. I'm taking my 12 to "The Factory" (Factory Pro), in San Rafael in a couple of months for a full map, but I'd love to have a copy of the map you've mentioned to Scott S. Thanks in advance!

My bike idles great & I haven't noticed any surge...of course I set my idle @ 5000RPM so my bike never sees those low spots!! HA HA HA



On a serious note - my bike really does idle great...set at about 1200-1300 RPM. I haven't really noticed any surges in any RPM range. The one thing I have noticed though is that once in a while when I get on it, it will stumble for a second or two...almost like it is being fuel starved? Can't figure that one out - any suggestions?



Here's my setup
