Howdy all. I'm the proud new owner of a street-legal, ugly as sin, XR600R. It's my first dirt-bike and I really love being able to toss it around like I can. I just wanted to introduce myself to fellow owners cause I'm sure I'll be on here more in the future. The bike generally runs great, but I do have a couple issues. 1. The bike seems incredibly hard to start, especially when cold. I have to kick it, and kick it, and kick it before it will start, then I have to hold the throttle to keep it started (or turn up the idle speed screw) and I generally have to do that until it's fully warmed up. Even when it's warm, it doesn't start on the first kick. 2. Sometimes when I roll on the throttle and get to a certain point the bike will missfire and bog, other times it pulls just fine. the bike has had something removed from the exhaust (baffles, tip, etc., it's loud) if that has any influence. My dad thinks it's normal for a big thumper to do this and suggests I just don't go full throttle when it won't, but it seems excessive and it happens in the meat of the powerband so it should be pulling in enough air. anyway, thanks for any help. Chris.
