But if you've had the ECU flash then the whole system is turned off.

I had my ECU flashed when the bike was completely stock and it really smoothed out the whole bike. Definitely worth it.

I took my cylinders to a locksmith and he did it for free. It took him 30 seconds to make them all match.

I bought a set of red FJR bags and found a good deal on the FJ bag mounts on eBay.  

Pictures please!
 

K&N filters have a 17mm nut welded on the end so it makes for extremely easy removal. Also note that there are two K&N part numbers on the list, the 303 is just a bit longer than the 204, and the 303-c is chrome. And Amazon will almost always have the best price!

I went with gray, but red was a close second!
