I have yamaha xv535 , 1997 and my mechanic said if l don’t get good speed from it [which l don’t, 55mph its a bit meh] l might want to clean my carbs.
well l can go back to him, pay and done deal. def wont be doing it myself, but after few googles l found Petrol Fuel System Cleanners as an alternative.
Gumout 510021 is supposed to be best one but being american brand of course l cant get it here.
but saw this one on amazon:
in reviews someone used it on Norton and Honda. As those are designed for cars l am wondering if they do more damage than good, especially for older bikes. anyone tried ??
