Fitted the revised airbox (interior cleaned out, removed all of the pipes, triangular filters and gubbins inside, and made as large as possible within the original outer case) and made a crankcase breather for the cam box covers, fitted two long intake trumpets, checked valve clearances and adjusted manual CCT's.
Actually, that was yesterday, today I rode it, and it feels just like I've lowered the gearing- but it's still standard

Grunty bugger, now.
Last week I fitted the MIG high levels, but they're far too quiet, now I can hear the intake noise over the exhaust.
It'll only stay that quiet until after a track day I will book in June (probably Brands Hatch short circuit) then it'll be (ahem) "adjusted" until it sounds proper again.
So don't take the piss at Wales, I haven't gone soft

It's not falling off, it's an upgrade opportunity.
