dmc2028372 Posted February 4, 2017 Report Share Posted February 4, 2017 Hang on a minute. 25ml for 5 litres is 5 ml for 1 litre which is 200:1. That's way off. Should be 60:1 ish 1 Link to comment Share on other sites More sharing options...
sniper Posted February 4, 2017 Report Share Posted February 4, 2017 That's the amount Nick said was recommended today when I asked at the demo day. It does seem low, but then you aren't lubricating the main bearings. Link to comment Share on other sites More sharing options...
heffergm Posted February 4, 2017 Report Share Posted February 4, 2017 (edited) The Vertigo manual (http://www.vertigomotors.com/downloads/) says 0.75% fuel oil mix. That's about 133:1, which means 7.5mL per liter (37.5mL per 5L). It would be cool if the resellers and the manufacturer could publish some agreed upon numbers...

To be fair the Beta manuals 'recommend' a much higher ratio than anyone actually run or I believe the Lampkin recommend, so this seems pretty standard!

jonnyjibs Posted February 4, 2017 Report Share Posted February 4, 2017 I questioned this with Nick at VertigoUK, as there was a discrepancy between the 200:1 (25ml/5 litres) or 0.5% and the manual, which states 0.75% which works out at 133:1. Nick confirmed the 200:1 ratio as being the correct mixture. Link to comment Share on other sites More sharing options...
2stroke4stroke Posted February 4, 2017 Report Share Posted February 4, 2017 They seemed to run just fine on 50:1 when in the Lochaber area☺ Link to comment Share on other sites More sharing options...
telecat Posted February 4, 2017 Report Share Posted February 4, 2017 Been running the Combat Camo at 25ml to 5 litres since August. No Problems. Convincing your self you have 25ml in the fuel is entertaining. 3 Link to comment Share on other sites More sharing options...

sniper Posted February 5, 2017 Report Share Posted February 5, 2017 3 hours ago, oni nou said: And it also shows that if the Vertigo happily runs at 200:1 what a waste of oil/money it is running any of the later model watercooled bikes at more [oil] than 80:1. No not at all, it's because the Vertigo is fuel injection, the main bearings are lubricated by the gearbox oil; whereas a normal two stroke they are lubricated by the mixture!
