I'm new to the board, so I may be kicking a dead horse, but my '02 YZ426 motor is very hard to start, and I'm looking for ways to help this. I'm wondering if it would be better to get the Hotcams YZ426 Auto-Decomp. cam, or the YZ450 Auto-Decomp. cam? Why? Which would better suit a fairly stock motor (full exhaust & filter)? Also, what about the BK Mod? Is there anything else that will help starting?
