Left exhaust valve options ????
If you are following the the thread "We are a little stump" I have been in search of the reason our 06 300 has a different power curve than our 08 300. The only thing that has been obvious is the central exhaust valve is shaped different.In searching part numbers for the 2 bikes to see if there is a difference we noticed that there are 3 different options for the left exhaust valve. I went to GasGas USA to look at this. Maybe I am looking at the view wrong or the description wrong but just looking for other peoples opinion if this could be possible to have different left exhaust valves ???
