bikespace Posted April 7, 2006 Report Share Posted April 7, 2006 Mine is definitely groggy at 50:1. Much sweeter with less oil. Quote Link to comment Share on other sites More sharing options...
stump magnet Posted April 7, 2006 Report Share Posted April 7, 2006 I cant remember where but i read an article on two stroke fuel mixes and the article said that running too much oil can be as bad as not enough, The theory is that if you run too much oil the engine runs alot hotter and will burn or hole the piston etc.. personally i would run the reccomended mix, which for the 290 is 50:1 i think,two of my friends have 290's and they both run at 50:1 without problems, <{POST_SNAPBACK}> this is true by running a rich oil mix you are replacing fuel which burns well, with oil that doesnt, therefore weakening the fuel mixture causing the engine to run hotter which then cakes up with sludgey part burnt oil. 50:1 is not a problem if you must, but through my experience running slightly less oil makes em run sweater Quote Link to comment Share on other sites More sharing options...
