iv heard nothing but bad things about la sleeve never tryd them but thats just what iv been told. i was gonna get a 110 big bore kit for my ttr90 and every said they sucked so i went with 2bros. Hetrick Racing does great port work i had my scrambler90 done and she flys now kinda expensive though but i belive if i remeber correctly cheaper than trinity, go with wildcard or flotec they cheap and probally do great work.
