gilera RUNNER 180 CVT Service | SKR TPH Hexagon Piaggio | FMP-Solid PASSion |

how to service the variomatic / exchange the belt

pretty easy, just 2 things to be carefull:
1) the screw above the oilpump cog wheel, use the SHORT one, the long one blocks the cog wheel
2) before tigthening the v belt pulley, squeeze the belt into the clutch / driven pulley, then block it, then the you can properly put the v belt pulley onto the crankshaft stump, so the thick washer sits on the toothing of the stump

AC = air cooled
LC = liquid cooled

rest is easy peasy

i liked this setup, near to original status:

original exhaust no cat
dayco 834x22 kevlar
malossi cvt
14,5gr 19!!x17mm rollers PIAGGIO not malossi they are always damaged very fast, just adjust the weight by sandoapering the metal inside the rollers
outer cvt disc, 0,5mm distanced to the outside

intake area flowed
cyl foot removes, which blocks the intake
exhaust port widened a bit, but original timings
air filter box optimized with malossi soonge and additional small intake tubes in the top back
boyesen reeds
mikuni 180 carb of the early runners
its oval, and has a bigger area at low slide openings = more power

sebac fork
bitubo shock at the back
best tyres of course ;)
250mm oversize disk at the front


give DR PULLEYs a go, with the original cvt, cause watch this:
   • PULLEYs faster than MALOSSI MHR cvt ?!? / ...  
Never tried pulleys in a runner.
