Always listen to the voice(s) of experience.
Word, it definitely is.
Psuffix, though you may be a little lean, Kymco ships with a 78 in the carb and with the oem exhaust, you aren't (or at least shouldn't be) doing any permanent damage. Apparently at some point in their existence prior to 2011, they would send as a part of their derestrict kit with the smooth boss an 85 jet. When they changed it to 82 my dealer asked them why and their reply was that in their testing they couldn't really tell a difference.
Now, I am going to admit some stupidity here: in my haste to get started on the fine tuning of my cvt (and because I am a cheap bastard), I ordered a set of minarelli fly springs. Partsforscooters was waiting on their shipment with the qmb springs and I didn't want to wait, nor did I want to pay somebody else's price plus shipping. They are currently installed, but will get swapped out tomorrow when the new set arrives from pfs. I write this, psuffix, so you don't make a similar mistake. (Fortunately, I'm only out 10bucks and a little bit of around town use won't kill my clutch or pop the springs). Make sure to order correct parts the first time.
And for the record, my dealer/mechanic basically said the same thing about a torque spring when I started inquiring. I don't know if it's that they haven't tried such a thing, or if they don't want the hassle of helping tune. In my case, I kind of lean toward it being the latter, especially because it's a little shop attached to a dealership whose new scoot business has been almost outgrowing the size of the work area. They have been taking delivery of quite a few new crated scoots this year and it was only around January that they hired a second mechanic.
All that being said, psuffix, if you haven't already gotten some, get a bottle of Seafoam (walmart or your local auto parts store) and add an ounce per gallon of fuel when you fill up. That stuff is worth it's weight in gold as far as keeping the fuel system clean. I don't remember if in your post you had already gotten some, but figured it wouldn't hurt to put the info out here.
