Never come across a problem like this before and im abit confussed, the bike has been running really good but over the past week it dies and all the lights go off when you brake, lastnight it starting bogging at around 40 - 50 mph. anyone else had this problem? or know what it is? would be much help thanks
Does it die when ever it returns to idle? Have you changed anything at all? Have you given it a once over I.e checked the plug, ht lead, all connectors and electrical contacts? Doe it cut out if you pull the brake when it's on the stand?
say your ridding, and you get upto 40mph, it starts to bog but at 50 it clears up, then when you pull the brakes its like the ignition has been turned off and it dies but if you rev it, it picks up its revs again.
