Damm this is going to get expensive..
On my ZX9R the original D207 was shot at 6500 or so Kms. The replacement D208 is just about toast at 5600 kms and only 2 months!!!
It is ridden fairly aggressively, as witness by the bluing on the edges and not enough chicken to feed a starving man, but my god is that the best I can expect?
Suggestions or thoughts guys, other than to pull out a sparkplug or two, or switch to a moped.
