Fazer 1000 Jet kit / EXUP - vitman - 26-08-25
Hi everyone. I’ve recently become a happy owner of a 2005 FZS1000. The bike is awesome, and I’d like to improve it further. Unfortunately, when I went to service the EXUP system, I discovered that the valve had been removed and the muffler welded. In Estonia and neighboring countries, it’s very difficult to find a header with this valve.
So I’ve got a question before I start. How badly does the absence of the EXUP system REALLY affect low-end performance? I ride about 80% in the city, and I’d really like the engine to pull well at low RPM right away.
I found a company on eBay that makes jet kits for the Fazer and other bikes as well. They’ve sold over 100k kits and have around 40,000 reviews. From what I understand, they select the kit based on the bike’s setup.
So here’s my main question: if I order a kit for a completely stock bike but with the EXUP disabled, what will come out of it? Will everything run fine, or is it better to restore the EXUP by any means?
Thanks
