Yamaha YZF R1 Off Roading

Have you ever seen this? A super sportbike made for mad speed and mean cornering transformed into a off road motorcycle. From what I can tell, only the handlebar has been changed. Ok, this is an older Yamaha YZF R1, but he certainly must have softened the shocks to get through the woods. Seeing this, it reminds me that I have to stop whining when I drive on a dirt road.

Engine Warning Alert Light

Yesterday I noticed on the speedo that the 'check engine light' was on. I got very nervous. At first I thought the symbol resembled a gearbox. When I came home, I looked through the Yamaha Owners Manual and found it to be the check engine light. Error code 42 also shows up in the speedo. Error code 42 stands for faulty speedo sensor and/or faulty neutral switch. In my case it's the speedo sensor. I have not had the speed showing up on the speedo and knew something was wrong. I have to take out the tank and find out

Yamaha YZF R1 losing tire pressure

I hate it, when I got the bike, the first time I drove it, it felt really weird, it wanted to keep going in a straight line. After visiting r1-forum.com (best site on the subject) I got some good pointers. The reason was almost so obvious I totally ignored it: tire pressure. I measured only 12psi in front tire and 15psi in rear tire. Gosh... Problem is I pumped air in the tires to spec (36psi in front 42psi in back), the day after it went down like 5 psi. I hate this stuff. What does this mean? Do I have to change the tire or valve? I have to figure this one out what the cause is. Maybe I should just put a tube in to avoid this in the future.
