I have a speedfight 2 100cc WRC and when its dry weather it works and runs perfect but soon as its raining it cuts out on me and i have to wait like 20 mins befor it starts back up i have changed the spark plug and put a new Air filter on the bike but it still is causing me problems?

the rubber flap that was on the bike will have fell off , as has been described put a new rubber flap back on, any piece of plastic /rubber works fine . in mean time clean and dry all around area [wires plugs etc] and spray with auto electrical sealer 1/2 times let it dry 10 mins before 2nd coat and that will work as well . electrical sealer is cheap £3/4 , you get it from auto shops or even petrol stations . this fix stops the spray water from wet roads getting to your spark plug, instead of waiting you could also carry WD40 water repellant around with you its a fast get you home fix

rear wheel is throwing the rain onto the sparkplug cap making it cut out common fault. try putting a rear muddguard off another scooter on to fix it.
