I read on some other forum.......
That on a YZ250, they put a 3mm (1/8") spacer in the exhaust(stock)...and that gives it much more bottom end?
so i pose this to the real experts (KX RIDERS).....is there any truth to this...and offcourse..will this affect the STOCK KX Pipe?
This is much MUCH cheaper than a FMF Gnarley.
Willing to try it. but i don't REAAALLY wanna waste my time, if it does NOTHING...
Scary thing is....IF 3mm makes n difference in power delivery...what difference will all the dent in my header do?
