Yamaha quad cold start problem

[freed007]

I need some suggestions, my Yamaha Bruin 250 quad 2005, does not start cold. I can pull it and pop start it. It works fine after it is warmed up. I pulled and cleaned the carb and checked the choke, any ideas? Thanks.

Hi, check your valve clearances, these quads are well known for tightening up on the valves, 9 times out of 10 this sorts it....:cool:
