Canary77 Posted November 10, 2012 Share Posted November 10, 2012 Hi All Just going through registration of my old RD250DX in Dubai, just air freighted out from UK. Hoping to get a little less smokey before I have to register at RTA. Not many old two strokes seen aroundfout here. Any tips on getting the mix right to get less of a smokey trail? Cheers.

Moderator Airhead Posted November 10, 2012 Moderator Share Posted November 10, 2012 they all smoke and smoke a lot more until the engine is warmed up The pump will deliver a metered quantity, this isnt really adjustable...is it an issue there then? :greetings and Link to comment Share on other sites More sharing options...
dt502001 Posted November 10, 2012 Share Posted November 10, 2012 Welcome aboard you could go pre mix with a full synthetic oil some can be mixed out to 100:1 also shimming the pump to stroke less will make it smoke less. Link to comment Share on other sites More sharing options...
