VESPA 200cc O-TUNING light | FMP-Solid PASSion |

116kmh gps topspeed, reving 7600rev now = +1000revs! & same fuel consumption! OPTIMIZING the original px 200 cylinder with 1 real and 2 closed fake ports is fun as there is quite some potential hidden. this LIGHT version is simple: just porting WITHOUT cylinder timings measuring & calculation! so no worries ;o) its easy peasy! check the pics and copy it, you will be amazed, trust me.

O-TUNING LIGHT is optimizing these things:
exhaust port shape / transfer port timing / opening piston / carburettor & casing /
extending intake & flow the crank cheek

& some further tips around servicing a vespa engine
- fuel supply
- primare screw nut
- gearbox oil sucking issue
- healthy ignition

otuning LIGHT rod.experience by owner, bike has a spark plug temperature sensor and supa tuna (lambda sensor 2rich/lean indicator):
an experienced world traveller and motorbiker:

1300km (190628)
"..bikes running well 0-80 is much much faster and smoother and CHT is cooler by 10-15c which is good. "
"6.5 l/100 wot, 5.5 medium/fast, 4.5 medium/slow, No leaks etc"

4000km (190712)
"engine is running like a top 😎, a good job it’s much nicer to ride than original and a lot easier to keep in tune too."

6500km (190724)
"..it’s running well, flywheel has now slight movement, but very, very slight. This is at 6500km since rebuild now.."

9000km (190730)
"At 51,000 total now and engine is same, no issues at all. still much easier to keep in tune than the stock set up. I think the stock engine is inefficient so it masks the jetting a bit. Sure really lean or rich is obvious but it’s hard to tell difference on hot of cold days or when there are small changes.
With the o tuning I can set the jetting/mixture perfect on 30 degree day and leave it run a bit Rich (got down to 0) when it gets colder and not touch it at all! It’s just more obvious what the engine is doing now.
Really haven’t touched it much for the last 5,000km. Which is nice."

17.000km (1911) in africa:
116 gps top speed
"revs up to 7600 (original only 6600)
same fuel consumption
way more sensitive to jetting
needs 5 sizes smaller mj in higher attitude than stock engine"

after 40.000km (2021) review:
"revs much smoother, easier and faster.
Top speed reached faster, there is an extra 1,000 USABLE rpm. O tuned engine I shift at 6500 easy. Original at 5500 or it’s too strained.
O tuned u can sit in third at 6500 all day up steep hills etc.
engine also will over rev to 7600 no worries.
original is strained at 6500 - big difference for downhill overtaking ;)

Fuel consumption is the same:
4.5l at best (around town, low speed etc)
5.5l normal (village, 2nd roads etc)
6.5l flogging it hard (flat out-whole tank)
this is for 2 up with 35kg gear (165kg total)"
