24000 mile service

[unfazed]

I check mine on the 1000 and 600 religiously at the 24000 mark. The 1000 had 8 out of spec where as the 600 were al within spec. At the 48000 mile mark the 1000 was fine but the 600 had 5  out of spec. At 72000 on the 600 all were within spec. My advice is to check them at the recommended intervals as you will not know from listening to the engine if clearances are tight. The old adage "Loose tappet annoys the rider , tight tappets annoys the engine" It will give you peace of mind also knowing everything is fine.
