Ok I couldn't take it anymore!!
I had to put the M4 exhaust back on the wife's FZ...
note: the dealer put the stock pipe back on to sell because of some EPA bs
...anyway YES! The little crossplane 700 motor sounds Fing badass again!! Super throaty wind the sweet crossplane growl:rock:
I didn't put the dynojet back on being the wife is still learning...
My question is: Will this cause the engine any issues running this exhaust without the power commander? Will the FI compensate?
One other question is: the dynojet has been off the bike for many months, it was only on the bike for 1200 miles, will it keep the tuning it had when disconnected or will it have to be retuned?
Thanks for any advice
First of all, a power commander isn't going to turn the 700 into a 900... If anything it'll probably smooth out the power band making it easier to ride, so I wouldn't use a newer rider as a reason not to install it.
Secondly, assuming the bike had a cat, does this muffler remove the cat? If so I would suggest running the power commander for sure, as that will drastically change the flow characteristics. If not, it probably won't be horrible for it, but as I stated above I don't see any reason not to install it.
If the bike has an 02 sensor in the exhaust it should be able to compensate slightly, but based on my limited understanding of motorcycle fuel injection it will only alter it at lower RPM's and at high RPM's everything will be running as originally programmed with no change from the o2.
Thirdly, the power commander should still have the map stored that was in it when you removed it. I would still hook up to it and confirm that it's the right map for that pipe, but otherwise you should be good.
