Gas already has plenty of additives... best thing you can do for your jets is ride...

I let mine sit, then ran it, then let it sit,, Id have to put it on prime, cuz the gas had evaporated outta the bowl, Decided to drop the bowl,, it had green goo in it. Not oxidized copper green goo, but some residuedoo from the evaporated gas. If youre parkin it for a while, drain the bowl, & For Sure, change the bowl screws to allen head SS & use antiseize. If youre gonna keep the bike, carb service can be expected once in a while. At least till ya figure out how to avoid needin any..
Im pretty fond of the Spark PLug door mod, too. Pullin the tank to get the plug just irked me. Of course, once the thing is all sorted out, that kinda stuff just isnt so important. The guy that got mine got a very "REady to ride" machine.
