does it happen at tickover?
when you blip the tthrottle only?
or all the time?

i very much doubt that the problem is wear of either the rings, bore or piston.
the tolerance levels are minute with nikasil compared to air cooled & a cast iron sleeve.
the reduction in friction is better & there is no glazing involved. it's an all wins & no loss situation. the only time you lose is at the wallet.
i used 2 sets of barrels over 13 seasons of racing with open carbs on my roadracer. i used to internally mic the barrels & the wear at 3/4 barrel height was .0005" at worst.
everyone is shitting themselves over 'how long before i rebuild my engine?' but i can see these things doing roadbike mileage if they are well looked after.
they would last even longer if we left them at WR timing. remember it's revs that kill!
