i asked about the problem to the shop i bought my bike and he said that its not a problem it only happens when the bike isnt warmed up.. is that true? does your guy's bike lag in first until your bike gets warmed up?

Also, my gas seems to burn very quickly. I filled up already twice this week. around how many clicks(kilometers) do you guys put it in reserve. i usually put it on reserve after around 90 kilometers.. but i guess thats because i rev up to like 9000...
