So i have a 200 ZR 500. Lately i have noticed that the sled is a little bit boggy. It starts right up fine, stone cold, within three pulls. It will idle for a minute with the choke on but wont idle with out the choke. It will stay running if i keep giving it throttle. The when i am riding the sled it is a gamble of whether it will run right. Sometimes it is really boggy and you can put the throttle to the bar and it wont go over 40 and wont get into the powerband. Then other times you will hit the throttle and the damn thing will take off like a rocketship. Guys got any ideas of how i could fix this?
