before you get the tool box out and give your self a head frying make sure that you have the correct grade of oil if its motor bike oil you wont have a problem though if its normal car engine oil you will get clutch slip try changing the oil and put on a new oil filter you will get all you need from halfords i sugest an engine flush before you change oil this should cure your problem failing that mate then its the clutch hope that helps

the problem you have there is that they are not supposed to seperate and are infact complete units thought if you suspect that this is the fault have you checked to see if any are loose? also i have see before that this is not the problem that it is the spark plugs either loose or old try changing these first and if the problem persists try Ebay for the coils they arnt usualy that expensive hope that helps good luck
