I wouldn't think you'd have a 20 degree difference between the exhaust pipes under normal circumstances. Full disclosure - I don't have a 4 cylinder NH - anyone want to confirm / deny my thinking here? -Joey On Mon, Apr 11, 2011 at 9:25 PM, Scott McKinley <[email protected]> wrote: > The exhaust pipe temperatures read when sitting on the bike: > > L to Right: > > 149 > > 147 > > 129 > > 121 > > Power seems a little low at less than 3000 rpm, but above doesn’t miss and > has plenty of power.
