Help Kickstart took forever

[Brandonkam]

I bought my 2004 crf250r this summer and had no issues with it. So I recently went out on a ride for the first time in a awhile. Now that it’s colder out we wanted to explore. When I started the bike it took a long time to start, like, over 30 kicks. I had choke on and wasn’t trying to flood it but it did eventually start. I had fuel off during transportation and did the usual stuff. So after I eventually got it started I was completely worn out and it ruined the first part of my ride, the bike ran great and only starting was the problem. Does anyone know what the problem could be or how I could prevent in future?

How did you make out? I'm not a 4 stroke guy but you may have some leaky valves that either need to be adjusted or re-seated.
