TonyGee Posted March 25, 2021 Share Posted March 25, 2021 try a new plug, and check the cap for damage. Quote Link to comment
Jaydee Posted March 25, 2021 Share Posted March 25, 2021 And check the HT lead for cracks. Quote Link to comment
Moosehead Posted April 3, 2021 Share Posted April 3, 2021 Check the plugs i have had this problem and after checking coils HT leads it was the plugs.also make sure you are buying genuine NGK and not the copies Quote Link to comment
wsn03 Posted April 4, 2021 Share Posted April 4, 2021 For some reason no one can explain Bandit plugs are a weird and delicate science. They seem to last 5 minutes, and for some reason no one understands they never recover from being wet. They tend to be the home of all electrical problems (I've had a mk1 1200 from new, 12000 miles and on my third set!) 1 Quote Link to comment

wraith Posted April 4, 2021 Share Posted April 4, 2021 Mmm, this maybe why I go through some many plugs. Bike stops running on one cylinder always random, change the plug for another plug runs well, then it does it again etc etc etc, now got 4 sets of plugs that get swapped about each year.

They ain't designed to be excessively wet with fuel though! Rich AFR may be tolerated till they foul but not recommended! Quote Link to comment

The strange thing is, I can put the same plug back in next time and it works just fine Plugs are not wet or black or Sutty they are a nice tan/brown colour. Did put it down to bad plugs but as people have said above maybe a cap problem. Quote Link to comment
paddle Posted April 5, 2021 Author Share Posted April 5, 2021 I have had an issue in the past that not one plug would fire spent days trying to find a problem.A set of new plugs and it was perfect. Quote Link to comment
