It won't start
So I've got all my leaks sorted now except for the radiator. I've got the bike carbs mounted and the fuel line fitted. Bike pump runs and charges up the pressure (ran for about 30 secs slowing down till it stopped). I held the throttle open slightly with a screwdriver and tried to start the engine. It cranks and you can hear what sounds like air being released but doesn't start up. After letting it crank a bit then turning the key off, I tried again. Still no joy and after a few minutes of trying this the battery seemed to die as the battery light on the dash got really dim while cranking and it sounded like it was really struggling to crank. I took the battery off thinking it must just not have had enough charge and sure enough it was empty when I connected it up to the charger. I left it for a couple of hours till it had a good charge and tried again but with no luck. So I'm guessing enough fuel/air mixture isn't getting through from the carbs into the head or I've got no spark. Any ideas what I can check to get it going? (note I'm running a 1.8 CVH CFi with a bike carb conversion so it's distributor-less and trying to start it up in limp home mode with only the edis and no megajolt)

Take a spare spark plug, pop it in the end of one of the plug leads, then connect a jump lead from the metal thread of the plug to the negative on the battery.
Turn it over and see if you get a spark. TT

Ok so I don't have a spare spark plug. Noob question but are they all the same size etc as I'll need to go buy one from somewhere.. I suppose if i need to replace them I'll need a tool to get them out like http://www.google.co.uk/products/cat...d=0CLsBEPMCMAc ?

You may have damaged them when you had the head off if they were left in place Definately get a tool, get a new set of plugs and then check for spark, a local motor factors will sort you out It should fire really easy, even in limp mode, mine fired first go You probably have damaged plugs or no spark or possibly both! |

If the engine has been standing for some time you may be short of compression due to the lack of oil in the rings . Try a squirt of oil down the plug ports then spin over a bit before putting plugs back in (having checked for spark).
Its worked for me in the past. |

Remember to check that you have oil pressure before you start it up once you get the spark sorted
