I have a stock ttr 125. It has quite a restrictive muffler, would reduced back pressure be good for it ? The muffler altogether could be removed without there being valve or other damage since its 4 stroke ?
From the factory the carb is set to a lean fuel mixture. Would a more balanced mixture be better or only shortern warm up time ?
Straying from the subject, the stock front sprocket is 13T. A 14T sprocket swap is common for greater top end. 15T sprockets are now available, would this enhance top speed quite alot ? I dont mind losing some acceleration.
