You are shitting me? Thats not the real price? Has to be....we saw pictures of Volfy's already?
Ozzy, As far as the reflash goes, Ivan only has the one for our Ninjas, so you are good to go with the header. Its optimized around the header, but still work well with the stock header, too. No need to send it back.....you can call him, bu ti believe this is correct.
Unless you did it years back. Ivan updated it in ..what was it, maybe 2018? If your ecu says "E6" on it, I believe that is the latest. There may possibly be an e7. Do you remember the guy who was worried about his fast idle? When the bike was cold, his idle speed moved around a little bit. I know Ivan got a hold of a z1000 and fixed that. It was never an issue, once the bike was warm, but...whatever, but that fix may be e7.
If you dont have e6...if you have e 3, 4 or 5...then for sure send it in. I did not as that idle thing never bothered me in the least. That step between e5 and e6 is unreal and a must do.
