section swept Posted December 17, 2019 Report Share Posted December 17, 2019 These engines were designed when the oils were what was available at the time. Now modern oils can be used more sparingly, so the mix ratios can be reduced. However those newer ....technical.... oils can still be mixed at the old ratios 40 or 50:1 purely for peace of mind....I run my 348 on 50:1 synthetic.

teamferret Posted December 18, 2019 Report Share Posted December 18, 2019 The guy who does most of the reboring and such work around here, maintains that bikes with a cast iron liner can't go lower than 25:1 as the clearence has to be more than a coated bore and the gap is too large for the diluted oil to fill Quote Link to comment Share on other sites More sharing options...
