What's up guys & Gals?? New to the forum because I retired my 2 smoker for a 2000 yz 426. Think I got a good deal, bike looks brand new with very few hours for $1900. Anyways the bike is all stock and I need to know which sparky works best with this bike. I ride trails only in Michigan for the past 25 years and just starting to learn about this "Thumper" stuff. Any help? Thanks.
