Hi Rocketman,
Is there any comeback if the tester damages your vehicle?
Maybe its a good job theres no MOT on motorcycles over here in Ireland?
Looking at your bike(verynice!) it looks in the photo that you have suppressed (red)NGK plug caps???
These are not recommended for mag ignition bikes, as it weakens the spark, making starting harder
Black, unsuppressed NGK caps are available, or have you had the mag converted to electronic???
Best Regards
John O R
