07 sm125 exhaust

Recommended Posts

im looking at getting a new pipe for my sm125 either dep or fmf but have been told by huskysport uk that both pipes can cause engine seizures and other top end problems, anyone had any experiences of these pipes or problems with them fitted?

no direct experience ,

I had a DOMA on my WRE / CR,

they are correct that there can be issues, mainly where the carb is not adjusted properly to suit the "free -breathing" pipe.

you would need to re-jet the bike and go from there.

lots of people who sell used pipes include the jets,

try a search for WRE 125 on here,

remember this is a US based forum where they so not get street 2-strokes,

there have been a few WRE / SM tuning threads though so have a search,
