The Kit itself is perfect!!
Great filters and better performance!
But the instructions that come with the kit are in a very small font, and therefore hard to read, also the pictures that are shown in the instructions are not very clear.
When installing the kit we discovered that the kit gives you several choices how you want to install other parts, this is a pro!! But it is not specific mentioned that you have a choice, this can give you some headache when installing and will cost you extra time installing it.
It is recommended to let it be installed with/by an experienced mechanic!! (I did :)
Pros: Great sounds, good looks and performance, shipped very fast. I personally like it very much.
Cons:
1. Difficult to install for beginners, have a professional install for you, or make sure to research enough before you take on the DIY project. It took me quite a while to figure out what the heck I'm doing once I took my bike apart. (An honest word of advise from a total beginner)
2. Oil spray from rear crank shaft breather. make a plan for modification before you start project. Either the collection can or relocation.
