hi, i have taken the power valves off my KR-1S and forgot to put any makings on them, is there any way i can figure out which way round they should be put back on? also how important is the tolerances in the power power valves?

look in the KR-Kive section, you can download the manual

There's a small flat on the top of the valves that marks the 'out' direction of the valves.

There's a good description on the Team sparrow site as to which way these flats should be pointing as it's hard to make it out in my manual.

Failing that, take the exhausts off and peer up you'll soon see if they are 180 degrees out
