  1. I also posted this in the jetting forum. Check this out. http://www.thumpertalk.com/forum/showthread.php?p=4611293#post4611293
  2. That's what I thought. Thanks man!
  3. OK that makes sense, I'll bet the bike did sit over the winter. Can you shed some light on the air leak thing. Thanks.
  4. That is why I'm confused, because theoretically you should have to lean the bike out when you increase elevation and/or temperature. I can't understand why hotter temps would worsen the effects of an air leak either. But that's why I'm asking you guys.
  5. I'm not sure if it sat or not but it is an SR.
  6. Hello everyone. I'm somewhat confused. My freind bought a KLX400 from the Houston,TX. area and brought it home to north Texas,about 1000 ft. increase in elavation. He rode the bike (which the previous owner had installed TT case gaurds on BTW) for about a week when the weather got warmer (upper 70's low 80's) and the bikes performance declined and the idle started hanging. We both work at a motorcycle dealership where he had one of the mechanics take a look at it. The mechanic richened the fuel screw which seems to have fixed the problem. This is where I have gotten confused. My initial suspician was an air leak which the mechanic could not find but told me the symptoms of which would worsen in warmer weather. First, why would his bike be running lean after being relocated to a higher elevation and increased temps? Second, why would warmer temps cause the symptoms of an air leak to get worse? I am assuming all was well with the bike at it's former home. If anyone could set me straight I would greatly appreciate it.
