johnnyboxer Posted January 17, 2005 Report Share Posted January 17, 2005 Which Oil is best for these older motors? Currently using Castrol TTS, but is it too good? Mixing at 50:1..........is this about right or could I go up to 60 or 70 :1 on a better oil. Seemed to run a bit smoky @ 50:1 Also what's the best gearing set-up - Rear is currently on a 48t. However I seem to remember somebody mentioning 9/51t or was I imagining it?? Quote Link to comment Share on other sites More sharing options...
