So ya used ta be able ta leave fuel in the tank and not worry about it going 'off or stale'. I get twitchy now if me chainsaw fuel is more than 4 weeks old but seeing as i get thru a fair bit s'not bin a problem.
On yer TDM's do ya drain the tank dry in the winter (will it rust a bit internally with no fuel in dare?) or do ya brim the tank and mix in an additive loike Seafoam etc?
What do ye recommend?
