When I give it throttle it doesn't pick up for a minute then it has all the power but it will do it again if u slow down and try to crack on it again can anyone help me

 

It's either a lean bog or rich bog by the sound of it. Don't over look obvious things like a new plug,clean air filter,make sure you have a good flow of fuel to the carb. If these check out,then check for any air leaks around the intake manifold by spraying contact cleaner,wd40,etc and see if you notice any changes in the way it runs.If this check out I'd go into the carb and at least install a new Shindy carb kit.Yamaha YFS200 YFS 200 Blaster Carburetor Carb Repair Rebuild Kit 1988 2006 All | eBay
