Cheers Mate Well to know that you do need to re-jet the carburettor up, you will need to do the plug-chop test, this is where you ride it for a while then check the spark plug and see what colour it is, if it is like a sutty black colour you need to go up in size on the jets, go uo in 5% bigger that the original jet. and then keep doing that till it is the right colour. It will help if you have a Haynes manual to tell you what the correct colour is. Thanks Link to comment Share on other sites More sharing options...
