Snatching Bonneville Throttle.

Hello, I have a 2015 865 efi that has only done less than 1000 miles. The problem is a very snatchy throttle particularly on deaccelerating. the bike really engine brakes to fast and takes the pleasure somewhat out of riding an otherwise fantastic bike. I have fitted a boost plug and this has helped some on acceleration (but not completely). I have heard of other riders with this problem and was wondering if there is a proven or tested fix?. I will try anything that will help because If this was cured it would be a superb bike and I might even get a good nights sleep. any help would be most appreciated. Thanks.

 

Thanks Linx, I will look into it.
p.s This is my first post and I am not sure if everybody can see it. I dont know if I have done it correct!
