johnboy999 Posted February 3, 2016 Share Posted February 3, 2016 Hi all , just got a 175 Yammy trials and the guy said he uses silcolean 2 stroke oil at 50 to one would this ratio be right and do I need the standard 2 stroke oil of silcolean? Thanks for any Imput John. Quote Link to comment Share on other sites More sharing options...
suzuki250 Posted February 3, 2016 Share Posted February 3, 2016 nothing wrong with silkolene, but I do use it at 40:1 on air cooled bikes (without any problems or smoke) Quote Link to comment Share on other sites More sharing options...

spen Posted February 3, 2016 Share Posted February 3, 2016 I use Morris fully synthetic MX two stroke oil at 40 to one in the trials bikes and 30:1 in the race bikes, never had a plug whisker. Doesn't smoke like the old days but always a good coating of oil when I strip the motors. Quote Link to comment Share on other sites More sharing options...

johnboy999 Posted February 3, 2016 Author Share Posted February 3, 2016 Thanks Spen, that will do for me then @ 40to one. Just mention did have in the seventy/80s a 350 clubmans Goldie dbd with lots of Taylor bits on it had to sell it when I went bust!!!! Remember getting £1000.00 For it , Doh!

spen Posted February 3, 2016 Share Posted February 3, 2016 If we kept all the bikes we'd sold, given away, broken, et cetera we'd be rich men. Here's some of what I get up to..... www.spencerracing.co.uk Quote Link to comment Share on other sites More sharing options...
2stroke4stroke Posted February 3, 2016 Share Posted February 3, 2016 I consulted Silkolene and they said 50 to 1 unless using in sand etc where a bit more was recommended due to the motor working harder. Semi synthetic. Oils are much better now than when we ran 50 to 1 thirty years ago. Quote Link to comment Share on other sites More sharing options...
spen Posted February 3, 2016 Share Posted February 3, 2016 We used to run around 20:1 in the old days...... Like bloody treacle.. Quote Link to comment Share on other sites More sharing options...
smokey125 Posted February 5, 2016 Share Posted February 5, 2016 The amount of oil depends on how your using the engine. Classic air cooled race bike steel liner 20:1 on R. Modern watercooled race bike plated barrel 30:1 semi. We used to run our TY175 at 50:1 synthetic. My Fantic, air cooled plated barrel 70:1 synthetic. To be honest I think you could probably run a TY with a less oil than a 50:1 mix but in all the time we ran the TY we never had a problem at 50:1.
