G'day All, My 1986 K100RT ex police is just about ready for the road. Pictures to follow shortly. The work completed to date has been:-
Replaced all fluids
Replaced all fuel lines including the lines inside the tank
Replaced brake lines with braided lines
Replaced rear master cylinder with Chinese one ( because I'm cheap)
Checked and adjusted valve clearances where necessary (inlet clearance were tight Exh. all OK)
Replaced spark plugs (non-resistor ones)
Replaced ignition coils
Replaced ignition leads
Checked fuel pressure which is OK
Replaced fuel filter
Replaced oil filter
Plus anything I can't remember.
After all this, the Goulburn bike is very difficult to start. After testing the quality of the spark from the leads to earth (ground) the spark was orange in colour and not blue.
I am seeking the collective wisdom and knowledge of this forum to point me in the right direction.
Thank you in advance. Cheers Tom
PS My guess is starter motor drawing too much current or the ign. coils are not getting enough volts. Battery is OK.Next to check is the ignition control unit connection. Should also mention that it takes about 10 cranks before it starts to fire. Also the injectors all have a good spray pattern.
