Got it in one Stevebowber wrote:I bet the one running badly was a dodgy plug cap or corroded HT lead, happens commonly on them (and other bikes primarily used off road) and in several thousand miles was the only problem I had with my 450, against that was I didn't need to buy one single upgrade item such as sump guard, handlebars or suspension (oops, I bought stiffer front springs).
I'm not keen on efi on this sort of bike though, having said that I bet it's not a common problem.

Fixed plug cap with electrical tape
Free ride with EFI that died terminally & couldn't be repaired in the field
