Im after some help on my S2 2.1 zvh. When i take it on a run and turn it off the engine doesn`t crank over properly. It is very slow to turn over and will not start up. If i leave it 10 minutes it then starts up. I have checked the starter motor and i have got 12v on the big connection when the ignition is on which drops to 8v when its cranking. The small conector has 4v when cranking. Would it be with the new larger engine that i might need a bigger starter and battery? Or could it also be that i haven`t got a heat shield fitted? Does any have a photo of the starter with the heat shield fitted as i think i got one in the shed but could work out how it goes or even if it goes on the zetec bottom end.
Thanks for any advice.
