I just purchased an 02 650l with 210 original miles. I was going to leave it stock but after riding 100 miles of dirt roads yesterday I discovered a horrible bog at wot and now the carb work shall begin. I've been reading about Daves carb upgrades and smog eliminator stuff for a whole day now. What I'd like to know is if I do the carb upgrades and smog removal work will the bike wake up ? It feels slow and sleepy and lacks throttle response. Where do I purchase the IMS smog block off plates ? And where do I get the jets mentioned in Daves artice on 4stroke.com ? Do I buy a Dynojet or JD jet kit ? It appears that a 58/158 or 160 is what I want to use, can I buy these from the local cycle gear or Honda dealer ? I was riding an 02 DR4OOS before this bike and honestly the 400 felt stronger not to mention lighter. The 400 haD a full exhaust and jetting however. THXS.
