Norman, I have just pushed my bike back from the third bike related/plug fouling/????? ride in a row. Since I have owned my 01'426 I have went through no less than 20 plugs. I've done the BK mod, I have played with the jetting but like the stock jetting best, and I received a new cdi. The new cdi made my bike run great, it idled, it started, it ran great yet the occasional new plug was needed. The last three rides it hasn't started, it's run like it's really rich, and it is up to it's old tricks again. The most exercise I get is pushing it back home! Please tell me what you've experienced is the same and you think that you have finally come up with the fix? It has crossed my mind to sell the bike, but when it runs good, I love it. Thanks, Brady.
