Title: backfire problem?
Post by: kemp2368 on August 05, 2010, 03:37:35 PM

hi all,i have developed a backfire problem on tick over,i have not used the bike for 1 week,and all i have done to it was changed my points cover for a nice shiny one in that week,if i adjust tick over to about 1800 it disappears?so is it over fuelling?? or is it just a bit of crap in the carbs??
any ideas would be really good thanks

Is it after revving?, could be a leak between downpipe and cylinder head.  Maybe your ignition timing is out.
