I've raced a lot with cars. I've taken my 636 to the strip one time before this and thought I did reasonably well for a beginner on a bike. This time I took my bike back to the strip with more confidence. The only thing that I've changed on the bike from the last visit is the jumper wire mod. Quite honestly I figured that this was probably just blowing smoke up my butt. Wrong. That damn thing pulls freakin hard. I wasn't ready for it. On the top of the rpm range it really pulled harder. My times were actually bad enough that I don't even want to post them. Four out of five passes I missed 2nd gear. I'm thinking (my own reasoning) that I was trying to shift too high and it wouldn't go. One pass after it wouldn't go into second, it wouldn't go into any gear at all until I slowed down on the return road and finall got it into first. Not sure what happened there at all. Anyway the front end just wanted to keep coming up. Every damn time. I've never had to fight that bike that hard to keep the front end down in first and even second. I need more time still and I need to get past my fear of the front end coming up. It just came up too fast and too easy. To make a long story short, the whole reason for this post is to say that I don't see how you guys do it. My bike is nowhere near a 10r. How in the heck do you guys keep those things under 5000 feet? Just had to vent a little.
