Service time is over for another 6,000miles. I decided a couple of years ago to extend it from the original 4,650 miles due in part to the well documented stability of the valve clearances and because I’m using the long oil filter and a decent branded oil. Whether I’m being realistic or foolhardy for extending the interval only time will tell. 😕
Valve clearances were all in spec but on the tight-side, so no need just yet to use the new Hotcams shim kit, but next time I’ll change all the shims by ±0.025mm to shift the gap back into its mid-range. That should see the valves good-to-go for at least another 50k miles. Everything else was absolutely fine, with just a slight tweak of the CO to lean out the idle.
The rest of the bike was given a thorough check over and happily all bearings and seals are fine, a squirt of grease in the rear suspension linkage keeping that nice and smooth. The drive chain and sprockets were cleaned and checked and after 33,333 miles (yes, that’s a genuine number!) they’re still good ….. This is the highest mileage I’ve EVER had from a drive chain. DID ZVM2 chain rocks!
