I only use Silkoline at 4%.
Running in.. took it easy for about 500ks, was running like a dream, then heat seized two up at about 100kmph on the motorway and it was about 35 degrees! . Inspection showed the clearances were way too tight. Barrel was matched to the new piston, seems right as rain now, had a pretty hard run, two up for about 150k's p the motorway and it didn't miss a beat. Drank fuel though, the motivation for a LTH reed kit.
OK, thanks for the info
