Re: The Kawasaki Z900 comes home : My Black Hornet So, having had some free time, I thought I should upgrade my exhausts. The stock one seems quite muted and was not providing me with aural pleasure. Hence, I had ordered Akrapovic full system, few months ago. It was imported in from Slovenia, through a local importer - dealer and took around 6 weeks after placing the order, to arrive.
The box and contents with bar code and patent information. It was an original piece alright. The parts was bubble wrapped and was placed in thermocol. It came with installation instructions and the necessary clamps and springs all with Akrapovic brand embossed.
I decided to get the long carbon end can rather than the commoner titanium shorty, as I was not interested in crazy loud exhaust. I just wanted a deep rumble and growl on opening the throttle and this carbon end can came with a db killer baffle in it. Also, I felt aesthetically, the carbon black end can suited the looks of the bike better.
I am a person who likes to get my hands dirty with the bike and I did not fancy spending another 3-4000 rupees at the dealership to get the full system change done. So, I spent a full sunday afternoon, at my parents place, doing the exhaust upgrade myself. Here are some pictures of the same. Being an Orthopaedic surgeon, and having worked with plates, screws and bolts helped.
The only thing which was a bit fiddly was the repositioning of the O2 sensor. I had to re-route it and carefully screw it to the opening on the Akra which was on the opposite side as the stock. The final look of the bike with completed full system.
The thing to be said about the full system is that it shaves off between 6-8 kgs off the total weight of the bike. I had changed the air filter to BMC previously and along with this change, the system is now a more free flowing exhaust. This means that the bike was at the risk of running lean. I did not want to get the power commander and tuning done presently. So just to make the mixture a bit richer, I got myself a Booster plug and did the installation, which was simple enough. I had to lift the tank to get to the airbox and had to piggy back the module in to the ambient temperature sensor. The bike certainly rides smoother now and it has lost the twitchy throttle issue. There were a lot of burbles, pops and crackles at deceleration and hence I got a rubber bung and closed off the air intake sensor tube. That sorted out this problem as well. Now, to try and keep away from the Kerala cops, who have a habit of catching exhaust modified bikes. Cheerio!  |
