[QUOTE="BigOgre, post: 1182360, member: 8712"] You're now sitting at 54,000 miles which means, if I did the math right, you only have 20k on it since you last had the TBs removed and properly cleaned. Seems doubtful you'd have material carbon build-up during that span, especially with the type of riding you stated. As far as the SeaFoam douche, I believe some didn't find it too helpful. PM or search a FredW post for his experiences with it. (A similarly related thread [URL="https://www.fjrforum.com/forum//index.php/topic/136159-cleaning-throttle-bodies/page-1"]here[/URL].) [I]"[M]ainly when I start moving the bike in first gear it starts moving and after that [B]it also has a small hicup and suddenly pulls harder [/B](it lost the smooth-linear response at very low throttle open degree). A similar symptom is faced also at gear change - due to this low angle throttle open non-linear response, when I change gear it has a rough transfer from 0 throttle to load."[/I] Does this hiccup thing occur at the same RPM each time no matter which gear or what speed you may be at?
