dodgy spark plugs
 

if one spark plug was dodgy would the bike still start?

On one cylinder.

Then again, by dodgy do you mean not working?
Or tried to sell you stolen goods?

Define dodgy!

In theory maybe, depends on what is wrong with the plug

if one plug did not spark, would the bike start,cos its unlikly for both plugs to pack in at the same time.....is'nt it????

if the plug doesn't spark it could be the coil rather than the plug, swop the plugs over and if the spark problem moves it's the plug. If still same problem then could be the coil.

did you get any Service history with your bike ?

i am just trying to elimenate probs b4 i start , what i want to know is if only one plug is good will the bike start?

Yes it will, but it'll run like a bag o sh*t. It wont idle properly and it may well stall. It wont rev up quickly and it'll feel sluggish to ride.

It will sound different if its only running on one cylinder to.

thanx for that, so either my both plugs are duff or its somthing else :reaper:

i will check/ change plugs if she still dont go its garage time :smt102

Does either plug spark, Have you actually removed the plugs, grounded them against the engine casing with their leads attached and turned the bike over? What, specifically are you trying to find? It's very easy to decide something is or isn't duff and be totally wrong if you're not checking in a systematic way as described by Razor
