richt Posted February 11, 2010 Report Share Posted February 11, 2010 I do 70cc to 5Ltrs (about 70:1) Castrol TQ-D is the stuff (ATF Dextron III) Quote Link to comment Share on other sites More sharing options...
des Posted February 12, 2010 Report Share Posted February 12, 2010 it should be a 50-1 mix 100ml to 5 ltrs some like to run a little leaner so 75ml to 5ltrs should be ok to just see how smoky the bike get or better still ask the previous owner what they used.

lightfeet Posted February 15, 2010 Report Share Posted February 15, 2010 Hi mate, I have exactly the same bike as you and you do tend to get conflicting advice, Gas Gas themselves will tell you premix is 80:1 then some people that I trust have said 70:1 the gas gas manual for 09 that I got with mine does indeed say 80:1, I played it safe and went with 70:1 as long as you have got a bit of smoke from your tailpipe when your pottering about it will be fine. Also I do believe it depends on the oil you choose, personally I use Castrol TTS which is a bit lilke p*** (As in thin) where as a mate of mine prefers Putoline for piece of mind as its a lot thicker, a guy I know a bike mechanic said that he used to assemble engines with a bit of putoline coated on parts as its sort of sticky so it was good for that. Always err on the side of caution I'd say, its much cheaper to replace a fouled plug than rebuild your slack top end! As for transmission oil, i use the Castrol QTF which is an automatic transmission fluid (ATF) its in 1 litre bottles and you need 400ml in your bike, so what I do i buy 2 bottles which is Quote Link to comment Share on other sites More sharing options...
