Questions after exhaust change
I'm pretty new with sport bikes so please have understanding if these are dumb paranoid questions.
My 2006 R6 had an idle issue where the rpm would bounce on cold start. The problem was the exhaust that had no muffler so I put on a stock exhaust few days ago and the problem stopped. But here are my concerns.
First, the new gaskets I got were a bit flatter than the stock ones and since my stock ones looked fine I decided to go with the old stock ones. When I fired up the bike I could se smoke coming from the area where the header meet the cylinder for a couple of seconds and then it disappeared and I haven't seen it since. I don't feel any air coming out when I hold my hand there. Is that normal?
Also, I hear this ticking sound that I haven't heard before, it could simply be because the bike was too damn loud before. A lot of other threads say its just the "Yamaha ticking sound" but someone also said it could be a leak. So my question is, does it sound like I have a leak? The bike runs perfectly otherwise.
