    Hey folks,

    just wanted to pass this along as an FYI: Someone posted up something about the rubber boot/junction between the carb/FI and cylinder having been cracked and causing weird performance issues. Well, lo and behold mine is cracked and leaking as well, tried a bit of silicone to seal it up but that was a no go. The rubber has broken down and every time I whack the throttle a bit the carb bounces back and forth. Not good, I changed it out today and WOW! The carb actually is working correctly again, enough that I have to go back to my jet settings from over a year ago.
    What seems to have been going on was the carb was little rich on the low end and lean on the high as the bike was beginning to feel "different", just didn't have the "snap" it used to. This didn't dawn on me until I read a post about this problem and took a ride on a friends 07 sm610.

    cheers,

    Mike

    Dean, it's a 2006 TE610. After I originally jetted it last spring and had an Uptite exhaust on it the bike would really run! But as time went on and in particular after I put a Motorsportz can on the bike just didn't seem to be as "peppy" as it used to be and at highway speeds it just seemed to labor a bit. I read a post somewhere about something similar happening (a bit different symptoms) and decided to have a look. Sure enough there were cracks all along the ring that the carb clamp sits next to. The new carb boot does not move at all and the bike is back to running like it did last year:thumbsup: Maybe I just got one made of bad pasta or something or maybe I shouldn't be riding the heck out of it? dunno? I have been accused of being a "throttle jockey" here and there, whatcha gonna do?

    cheers,

    Mike
