zimbobrad Posted January 13, 2012 Share Posted January 13, 2012 Hey guys' Need a bit of advice with my DT 125 R '89. I've recently rebuilt the engine and I've done over 1000 miles but I've fiddle a bit.... I've replaced the Rees valve with a racing reed and before I brough it, it had a DEP down pipe and a Big One End Silenecer... So to the point should I change the jet at all? Thanks, Zimbo Link to comment Share on other sites More sharing options...
Moderator Airhead Posted January 13, 2012 Moderator Share Posted January 13, 2012 might not need to, all you did was change the reed valve? do a plug chop if you are unsure Link to comment Share on other sites More sharing options...
