Hi guys I was hoping someone could point me into the right direction as to what I messed up on my bike. A little information about my bike: 2004 VFR800 Non-ABS Around 26,000 miles. Starting about two months ago my brake pedal started to feel mushy. Slowly and slowly I lost rear brake power until I no longer had any fluid in the reservoir. The front brake still worked fine besides this knock I would hear when braking at low speeds (presumably from the left caliper, the linked one). I rode like this for about a month and two weeks. Two weeks ago I swapped all the brake lines on my motorcycle with the Galfer Kit that I had bought. After about 10 hours of work disassembling the bike bleeding the lines etc. I finally put the bike back together and went for a ride. First thing I noticed is that under my seat I started to see steam, and when I went to pull the brakes the bike almost bucked me off. I felt a clunk and then the bike violently applied the brakes or otherwise stopped me in some fashion. I pulled over and noticed fluid leaking from the rear PCV Valve. Knowing that these bikes from this year suffer from PCV failure issues, I contacted Honda warranty and they told me to bring the bike in to a Honda Franchise Dealer. If they determined that the failure was caused by a defective PCV valve, they would cover the cost. At the time I did not know whether the bike trying to buck me off or not was related to the PCV valve as I didn't and still don't exactly know what it does. As I rode/ walked my bike to the dealer that was just a mile away with my hazards on I noticed that my speedometer was not working. I remember removing the sensor to be able to replace the clutch line. I thought perhaps the bike was trying to throw me off because I had misaligned the speedo sensor on the sprocket and it had shattered and now pieces of the sensor wheel were mashing about in the crank case cover. I could not verify as when I dropped the bike off at the dealer I didn't have the tools to take the speedo sensor off the bike and take a look. Honda ended up covering the cost of replacing my PCV valve and apprehensively I rode my bike home. Before leaving the dealership I took a look at my speedo sensor, and on verifying that it was just a little loose, I tightened it and I started getting a reading on the dash once again. About 3/4 of the way there I noticed my brakes felt different. They felt heavy, as If I pressed them and the pistons did not retract. I rode the bike with my emergency lights on and did not touch the brakes the rest of the way until I got to my parking spot at my apartment. Sure enough when I pulled the brakes the same thing occured, the bike stopped violently and gave a clunk sound. I have a short clip of the ride home to better explain what happened. The action is in the last couple seconds or so. Any input or suggestions would be greatly appreciated. I love this bike, but I'm a little scared of it now.
