No spark nc35

[rvfali]

Hi i wonder if anybody could help me, i have just tried to start my nc35 after it has been in a accedent, no luck i took one of the ht leads off and put a plug on it and laid it across the frame,no spark.
There is damage to the top farining and the clocks bracket is bent, is there anything on the back of the clocks that could cause it not to spark .
Also is there a way of telling if it is derestricted ??

Thanks for any help alistair

Firstly de-restriction is checked by either 1) riding it or 2) opening up clocks to see if the speedo dic is bent (google for a guide on this if unsure or 3) fitting a speedo converter will do it automatically.

On the spark issue, I think the best action is to firstly check the battery or get a jump etc (rule out battery first- if its cranking strongly then great), check the kill switch, then pull out all the plugs and check them individually. Let us know the out come then we can work off that, before you rip the bike apart to find its a duff plug or a kill switch.

cheers for that, i've just taken the battery off to charge it, so i'll try it later :)

I've just taken the rear 2 plugs out, looks a nightmare to get the front ones out i cranked it over with help from jump leads and the 2 plugs where sparking :D :D . i guess before it was not turning over quick enouth. Cheers for that.

I through that the front 2 cyls. would have started up, but no luck, it has not been started for 3 months, i did put half a gallon of fresh petrol in it, how does the fuel system work ? is fed by fuel pump.

Its gravity fed carbs IIRC. they need every bit of voltage to crank and are a pain if left for some time.

And if you give a lot of throttle when trying to start it they are easily flooded and the plugs are easily fouled.

Plugs are a tenner each...
Try it on choke and no throttle and go from there....

Many thanks for the help, another thing has the fuel tap got a vacume valve on it, ie fuel will not come out unless the motor is running or being cranked over??
cheers alistair

yeah the fuel tap is automatic,operated by a vacuum created when the engine is turned over!!!!


get yourself a multimeter,it will come in handy and make life easier when it comes to checking the condition of the battery etc.
