Ds250 upgrades

New to this forum just bought an 07 ds250. Was thinking of getting the fpp clutch kit and 14 tooth sprocket any thoughts. I think my quad has had work done already everything I've read says it won't spin tires factory have had it 3 week and already roasted a set of rear tires I can power brake it on asphalt and when I let off the brake it will ride a wheelie. Another thing any one have pics of shaved ds250.
