gasgas694 Posted April 20, 2011 Report Share Posted April 20, 2011 i got my gas gas 125 2005 out and started it up (hasnt been used in ages) after putting it back together givving it a bit of a service it seem's to run really smokey could this be to do with the oil mix or maybe the old fuel i used? the mix i use is super unleaded with 70:1 also round the exhaust pipe seems to be thick oil any ideas???

sherco125boy Posted April 20, 2011 Report Share Posted April 20, 2011 most Gassers and most trial bikes are a 60:1 mix of 2 stroke . Quote Link to comment Share on other sites More sharing options...
t-shock 250 Posted April 20, 2011 Report Share Posted April 20, 2011 You don't want to be using any more oil than 80:1, use a fully synthetic oil. Does the bike carburate clean? i.e. does it rev cleanly at all rpm's? Quote Link to comment Share on other sites More sharing options...
gasgas694 Posted April 20, 2011 Author Report Share Posted April 20, 2011 Yes the carb is clean i have cleaned it and yes i tick's over fine and when i was giving it a good rev i seemed fine except it was like puffs of white smoke Quote Link to comment Share on other sites More sharing options...

legionnair Posted April 23, 2011 Report Share Posted April 23, 2011 most Gassers and most trial bikes are a 60:1 mix of 2 stroke . Maybe if you are running roads all day you would want a 60:1 but for general trails and section riding 80:1 with a full syn oil is best.
