Hi there,

My bike has some air leaks (rubber hoses and intakes got craks) and during sell preparations idle speed was adjsted with them.
after my air leaks fixing i've got idle speed around 1100 RPM.

in case I've got about week to ride in this season (seems next week in Moscow will be quite cold to ride), should I worry about it, or I can wait with adjustments for next season?

you can wait till next season ...a high idle wont hurt

Privet!
Just get Charlie to pop over with his gauges and he'll fix it for you.
Some vodka may be required.
