u can actually hear it when the idle jet setting (and/or the mixture screw) is too lean, get a feeling whats too lean and whats healthy. too lean means dangerous, cause the engine will definitely die if u go outside the city and trash it :D :P

new REED valve si carb version:
   • vespa IDLE JET setting:  2lean & HEAL...  

setting the carb like this is a good basis for a testride where u can fein adjust the setup, no worries nothing will happen.

onroad behaviour of a well set ide jet engine
   • vespa ONROAD BEHAVIOUR #1/2: vespa S...  
   • vespa ONROAD BEHAVIOUR #2/2: vespa S...  
   • Vespa/LML si carb ONROAD BEHAVIOUR: ...  


how2start:
1) healthy engine
(no oil sucker, no false air, no blowback) ((see vid guides to each issue))
2) proper fuel support
3) meqsured main.jets (guide!)
3) warm engine

wondering why air filter is missing and what will change if u add it and the air bellow (see small guide btw how2 mount it)?!?

u are on the safe side! the naked carb runs leaner as it gets more air, so if u start setting it up without, the setup will get richer when u add filter/lid/bellow.

no, its absolutely no problem.to drive without airfilter/lid/bellow. no worries
tried also taking videos while driving
but enginw sound is too quiet and Vibrations to high (video pic gets wobbly)


NOTE: the idle jet is the reason for most engine killing and NOT the main jet. actually the engine cools down at full throttle, it gets really hot while cruising at the 050% throttle range. and an engine with power is mostly moved around 25% only original engines with no power need full throttle to get moving.

hope this prevent a lot of unneeded seizing!
drive safe mates :D
cheers
