My 1997 yamaha mountain max 600 backfires often and is allways hard starting when cold. The sled has " smart carbs" dispite two professional tune ups it takes about 20-25 pulls when cold to start and often while pulling it will back fire, once warmed up it starts fine. Then while riding and warmed up it will backfire I have installed new ngk br9es plugs and fresh gas.
Any suggestions ???????

Thanks Paul
