I have a 2006 200gs and have not been able to find parts anywhere. I have called zongshen and no one picks up. I have e-mailed and they never respond. Does anyone know a good site to find parts for this bike? I have found some sites that have parts for similar bikes, but I'm hesitant to order. Also if anyone in Indiana knows where a good place to have some service done on these, that would be helpful also. I'm trying to get a little more power out of my bike. I'm light enough that it does 70 with me on it, but I want to increase the acceleration. I'm thinking of re-jetting the carb and putting a new exhaust on it. If anyone has any other idea's I'd love to hear them. Don't want to change the sproket though because I don't want to loose any top end. Use the highway from time to time. Considered one of those boost bottles they use on pocket rockets and scooters, but I have a feeling those are a gimic. Scientifically they don't make sense. Any help anyone can give would be greatly appreciated. Thanks.
