suction hose vs ramair

[FurlanPx]

Hi I have a 177polini longstroke , malossi reed valve , 28 keihin, rz righthand and 23/65 with short 4th gear. I'm trying to carburate the engine, It's not simple, now I use a ramair filter, but I see in many of your vespas that you use the suction hose instead a ramair. So.. what's the difference? I remember that with the old engine (177 polini, cut crank, 28phbh with dreschrieber and a pinasco chrom) When I was trying to carburate with the ramair I can't reach good performances, instead with a suction hose I carburated it perfectly and the performances were great than the ones with ramair. But many people tell me that with a ramair the performace is better than the ones with suction hose. So..? :haeh:

The Performance is better with an Ram Air. With the suction hose the engine won`t reach the same RPM as with the Ram Air. But it can differ on each engine.

Using an 211Malossi with an suction hose you lose about 500Rpm I guess.

With an Ram Air you have to carburate it fatter to gain the same performance, that`s for sure, maybe thats why you had more power with hose than without it....
