So I have 2 bikes. One is a 2002 Honda 350 trx and the other is a 2000 ES. They are really the same bike just different shifting and year. The 2002 starts hard in the wintertime. I have to crank it over for a minute or more until it fires and then the battery is dead. I cleaned the carb and adjusted it and doesn't help. The 2000, on the other hand, starts within the first few cranks with not a lot of choke. What could be the difference? Once they are warmed up and ridden a little they are fine. Any Ideas? I posted about this a month ago on another forum with no responses.
