Hi everyone im about to buy a brand new 2013 later this month and im pretty excited about it. I know most people say riding a tw200 is the equivalent of riding a turtle but I currently ride a 2005 yamaha zuma 50 two stroke so going to a 200 and having never rode anything larger than a 50 I think that the tw200 will keep me happy for years. I had a few questions for you guys. I know the tw comes pretty lean from the factory and as soon as I get it I will probably change out the exhaust re-jet the carb, put a k&nfilter in and put tires better suited for the street on it. I was wondering if anyone knew the stock jet size that the tw comes with out of the factory and what size jet I should go with with the aftermarket exhaust and k&n filter on it. thanks in advance guys look forward to talking to you all in the future.
