Hi all. New member here and I have to say that I made the right choice! All my friends bought 4 strokes but I just couldn't bring myself to do it...glad I didn't because I have never had so much fun as I do on my 04 500! I do however have a slight problem. I found a post for the same thing a few years back, but no one answered the guys post. Here goes... My K5 shifts great 1st through 5th and back down to second but sometimes, not always, I have a hard time getting it into 1st. It just wants to stay in nuetral until I hit the shift lever a few times then it goes into 1st. This is a real pain when you got your groove going or approching a hill at slow speeds. The only thing I did was change the oil. It was my first as I bought the bike used. I tried the redline oil 10/40 because they were out of 20/50 like I wanted for the vegas heat. If you guys can help me out with any info, that would be GREAT! Also, I also noticed that when I pull in the clutch with the bike off and cold it makes a snap or popping sound. Not real hard but just enough to hear it. Thanks, Paul.
