Check the points gap, 2/3 need adjusting. Did this as per Hondaman's instructions in his book. Worked a treat. Then I hooked up the digital multimeter, put it around to Ohms to check the timing. This was done statically and when the reading on the meter when to 1 the point were open. 1/4 were good, slight adjustment for 2/3. Started the bike up, and checked timing again with timing light, spot on, checked full advance, all good there so job done. Bike sounded good. Now why is it that as the bike warms up the idle increases?
