I took my 2006 yamaha in for an oil change and had two new tires put on, a couple days later my bike couldnt go pass 45mph, it use to do 95 easy, the dealer i took it too stated it was the gas i was burning but thats not true i had this bike for two yrs and been burning the same gas, well, I took it to another dealer and he told me it could be the cluch,the belt,or the air filters, he put all brand new parts that i mention, and it still didnt go pass 45 so what can i do, could you please help me. My phone number is 229-460 8827.please somebody help me.
