I made the original comment about my wifes cb400t, let me clarify. It will do 120km all day, but its topped out give or take 5-10km. If She's in a tuck going down hill it'll hit 130 maybe, if she has to pass or get out of dodge it aint happening. I just dont think going through all the work the OP did for a 400cc twin is worth it and I fully appreciate the work that went into it, he did a great job.
