I recently purchased a YZ426 for my son for a great price. We mostly ride desert/single track. I know the 426 is a track bike, but for the price paid, it was too good to pass up. Here are a few questions: 1. He is only 130 lbs so needless to say he has a hard time putting enough weight behind the kick start and the starting routine seems to be difficult for him. What cam is needed for the auto decompression to work? I have a spare stock cam from a 04 WR450....will this work? 2. The bike seems to be very difficult to start after warming up. Last week, the only way to get it started after a 1hr ride was to bump start it. Any ideas as to the cause of this? 3. The bike seems to overheat easily when doing slow technical offroading.....does anyone make a catch bottle for the antifreeze like on the WR? Will a catch bottle for the WR426 fit it? Did thos even have one? 4. Does anyone have any other mods they recommend for making the YZ426 a more offroad oriented machine? Thanks in advance.
