Hi I have a cast iron polini 177 just bolted on with a revolver exhaust not got it on the dyno yet but what spocket do you recommend for the clutch I think I have a 20th cog in it and can you give me An estimate on jetting please
My 03 Vespa came with a DDR 177 kit, it kept playing up, so eventually had a Malossi 180 Kit fitted sadly my Fly Wheel Bearings went which apparently caused the rod to push down at the wrong angle and it scored the Piston head, it sounded so bad not even a year I had to change it, due ti the high fuel prices I went for the Polini Sport which came with a smaller Carb. I've complete 200 miles at 30mph but here is where it gets confusing as I'm being told different things, what speeds do I do next and for how many miles? really can't afford to wreck this kit.
Hi just vary the throttle position ,don't keep it fixed at a certain revs for too long ....its run in after 200 miles ...use all the throttle now it's less likely to go wrong at wide throttle opening than pottering around at 1/4 throttle 👍
@@shinyred Thank you for the quick reply, she's killing me finally but I love her very much have got the bug big time lol, just can't beat that feeling of me the Scooter and an open road.
Got a dr 180 kit the barrel needs reboreing for the new oversized piston but are the dr180 kits any good or not thought i would ask before getting it rebored cheers
its a fine tune adjustment for the idle jet ,there is no correct setting it depends on so many variables .........start at 2 turns out...let the engine tick over in neutral then snap the throttle open ......if it bogs down then revs ..turn the idle screw in half a turn ..if it gets worse turn it out one turn .....keep adjusting half a turn at a time till it revs cleanly and instantly ....thats the correct position...hope that helps
@@shinyred I hear you! but should be enough for a local town runner I have heard of the drawbacks, but get what you pay for I suppose - Thanks for the quick response!
the carb was standard and she made good power ,dont think you would see much gain from going larger on carb though ....only in fuel bills lol what exhaust do you have thanks for commenting James ;)

At last someone in the scooter world that actually knows what they are talking about . Top bloke shiny. Great work.
Thanks Nick ,appreciate you commenting ;)

Was this just a bolt on kit
Does the cast iron 177 polini kit got the same result as the aluminium kit
No it's less power, totally different kits
Got a dr 180 kit the barrel needs reboreing for the new oversized piston but are the dr180 kits any good or not thought i would ask before getting it rebored cheers
I would change it for a polini like in the video so much better power :)
DR - Inferior kit, don't bother.
Hi folks what size main jet do i need for a standard vespa px125 with a revolver exhaust and polini induction kit cheers
How many turns out is the fuel air mixture screw supposed to be on a standard carb and engine cheers

Cheers for advice
What you want is an instant pep and no bog or rev hang.
have you ever had the pleasure of dyno-ing DR 180 (tuned) with a malossi piston? if so, is it a good dyno? Thank you!
Yes a few, not the most powerful kit out there though 👌

@@gracchi132 they are a good kit compared to the standard they give a real gain 👌
@@shinyred I completely agree, after the scoot is on the road and the world is more lax, be awesome to see the dyno of the little beast! take care :)
@@gracchi132 ride safe and thanks for commenting ✨
is it plug and play or the port has been matched? what is the intake n exhaust duration of the cyl?
just plug and play ,i didnt time the barrel for durations......just fitted as per instructions .
you do some great work up there buddy..
Thanks Pete ;)
what carb did you use
26 mm standard type carb
@@shinyred cheers
wanted to get i vespa,but now i realize my 70cc runner is just as powerfull, and goes the same top speed :/
was there much difference between the two kit's
yes, the polini is in another league performance wise and its ali with a nikasil lining instead of iron ;)
shiny red Cheers what carb are you using i was thinking of using the 26-26 delorto
the carb was standard and she made good power ,dont think you would see much gain from going larger on carb though ....only in fuel bills lol
what exhaust do you have
thanks for commenting James ;)
Scorpion exhaust stainless steel
@@shinyred i use a 20;20 with the polini carb upgrade. tried a 24 and 26 but around town the 20 seemed best
