Expected speed from my setup

[eran_kTopic starterBerichten: 52]

Hi everyone,
With my Si, i reach the end of the km teller (60 km/h) and dont know my max speed.
From your exprience what speed can i expect with my setup:
Piaaggio Si montecarlo electronic kickstart

Motor: DR43 with stock head,ports matched to case,inlet enalrged and drilled to 13mm,13.13 carb with #74 jet and hi flow filter
Exhust: Proma circuit
Variomatic: Mallosi Multivar,7.5 gram rollers, 100mm rear pulley,rear spring still stock (got the yellow spring but not installed yet)

I’m on the heavy side (~115kg) so this can effect my top speed as well :bloos

thanks
Eran

I think about 70 – 75.
But like to here someone else his opinion.

[aapie90BijdragerBerichten: 823]

I think about 65 km/h

because of your stock ports (no boosterports)

[JarcoBijdragerBerichten: 2515]

I dindt see that, good question.
Is it the normal DR43 or the DR43 EVO ( with open boosters. )?

I asumed the 43EVO because you say you matched your ports to your case?

EDIT: I see it in your singnature: EVO power! 😀 So i stay with the 70 – 75

[eran_kTopic starterBerichten: 52]

Yes it’s the EVO, and i did matched the “Finger ports” to my carter as well

@ blacklisted: we have a special topic for this: the “hoe hard zal dit gaan topic”

I think the topspeed will be around 85/90

[BlacklistedBijdragerBerichten: 37]
