Sparkplug gap

Hello

Im about to change my sparkplugs, and I just wondered, does anyone check and adjust the gap on the new plug before install?
Ive always just put the new ones in

With conventional plugs it is always a good idea to check the gap prior to install. If you use iridium plugs, supposedly they come pre-gapped and checking is not necessary. That said I always check my plugs prior to install. Good luck.

Always worth checking new plugs. I believe the SW is 0.9mm. I'm using copper plugs but I previously had Iridium ones set at the same gap. Now, don't start on about plug types, it's been covered elsewhere.

I just put them in. Having done that and changed the air filter I had to slow down the tick over to 1000rpm, it now runs and slows better in traffic, engine should be running cooler.
The tickover is set by screws tucked behind a small rubber pipe ( see owners HB) for location.

If I remember correct the idle on silverwing should be higher than 1000 rpms? 1250-1300rpms I think I read somewhere?

The idle per Service Manual is 1,300 +/- 100 rpms, usually the best idle rpm for scooters with a centrifugal clutch is on the high side of the range, it engages clutch quicker, less hesitation/slipping/glazing/chatter, as the clutch is spinning faster/closer to engagement rpms, it will also hold the clutch engaged longer, if your idle is too low you could actually make it harder to drive slow, as clutch will be falling out earlier.
The specified or higher idle also affects/improves how the engine moves/flows engine oil, engine coolant and CVT cooling air. as all this system are affected/become somewhat inefficient when engine is hot. Yes, high idle will burn a little more fuel in traffic but is the best compromise, for the beforementioned.
