    tune up

    sounds to me just a good ole going thru + tune up is in order. from aircleaner to timing and valve adjustments ( if needed ) ,,, + since it's been running rich ,,, don't forget to clean the exhaust pipe out.

    Wow thats really shocking, i hope its more, but since i took the silencer off of the tailpipe how much would that boost the horsepower

    did u try adjusting the fuel/air mix screw twf?? my 185s did smae and all i had to do was turn it then set the idle right...and taking off the silencer and only having the header wont boost it much mx125...it gives it a little bit more torque but not much..i did it with mine ..but only cause it was rusted out..lol...im planning on getting a full cobra exhaust for it...hehehe...hope u get it runnin right twf
