huski Posted January 30, 2020 Report Share Posted January 30, 2020 They don't tend to alter much unless you rev the nuts off it frequently,then they close up which makes it harder to start when hot as the valves don't seal completely 1 Quote Link to comment Share on other sites More sharing options...
