Well, Good point. Because I saw that the main jet is a 150 on the TT600 carb instead of the 130 I have on my XT600E one. But, the XT600E runs better the ever before on the TT carb so I am happy for now. Would the TT600 then pull more power out of the same block or something. And, what you guys think I should do? It is running quite well on the TT carb only not at very high rev.. leave it like it is?
Then, I have a additional question that I cannot get answered by the service manual, It is about the tube/ valve displayed below. I thought this is the ''roll over valve'' according to service manual but also not sure about that. So my question, what is this tube/ valve for? and how can it effect carb performance? And, does it need to be in a certain position for the carb to perform at its best, or.. what position to put it in to make sure it functions poperly?
