So ladies....
I have an 07 zx6r that I bought used. Its in decent shape (but not perfect, beacuse we all know how people treat these bikes). When I start the bike up cold, It sounds like that valves are really loud and ticking a bit. Now I am a very sensitive guy to small changes in the bike. Once the bike runs for 10 mins down the road, the sound completly goes away and it sounds real smooth.
I had the same exact bike (my freinds) for a few days a little while ago. His bike had 4k miles and mine had like 7k. I started them both up, yet his sounded smooth even when starting cold.
Now that only crazy thing I can think of is this.....I recently did an oil change and used a car filter and not a bike filter. I bought a fram tough gaurd filter. The only thing I can think of is that a bike filter is meant for more pressure due to higher RPM's and the car filter poped the pressure seal inside which allows the oil to drain all the way into the oil pan when it sits a long time. So when you start fresh it takes a while to lube the heads. Is this totally off in left feild?
Is this something thats fairly normal? Am I just being too sensitive. I mean the bike only has 7k miles. Can the valves really be bad already?
Or does that sound like a normal problem for an 07 zx6r?
Thanks for the advice in advance...
