Thinking of upgrading to a corsa 70 kit

Ok i currently have the setup below and am thinking of getting a polini corsa 70 for more power. The things concerning me atm are that it will be a standard crank (4000miles), it has a 17.5mm carb dont no if i shud get bigger and finally says capable of 140kph is this with a gear up kit plz tell me what you all think thanks alot

 

any 1 plz?

 

yes you would need a new crank, and dont go for the corsa mhr rep is about the same price and its much better, 17.5 carb would run it but you wouldnt get the best out of it , try having a look round first before you aski bet this has been covered loads of times

 

i have tried looking round the search things is not to good lol and i thought the corsa had more power and was better so the mhr rep is better then and a new crank bollocks i dont have enough money

 

i chose an MHR-rep kit over the polini corsa

get a rep mate, you wont regret it...my scoot is flying

 

what do people think about me needing a new crank or is a new aerox crank fine

 

a new low mileage crank should handle it ok...

but it will wear out quicker

 

as dave said, also you are losing out on primary compression with a stock crank.

 

well is that cheap motorforce pro crank any good if so it will be that and the mhr rep wheelie fun :w00t:

 

Why not go for a doppler crank or something?
If its a case of waiting a week extra for the cash to have a better crank thats what id do.

 

I've got the corsa kit mate (Y)
and id recommend you getting a crank i got a stage 6 one
cost around 100quid but its worth it . just make sure u look after it =]

 

to be honest ive never used motorforce products,

so im not really qualified to comment on them.....

but why not have a look at the BGM cranks on scooter center, thats what ive got
and it seems more than up to the job

or as already suggested by eski007, The stage 6 cranks seem very popular on the euro scene, i notice a lot of set ups much wilder than a corsa/rep using stage6 without problems

 

Thanks loads i will go for the stage6 crank, corsa 70 and a 21mm carb from my 17.5mm cheerz

 

just looked on scooter-attack and all the cranks are out of stock apart from this: CRANKSHAFT COMPETITION TOPPERFORMANCES, LONG STROKE:As above, apart from a longer stroke of 40.2mm. Gives slightly longer port opening durations and increases capacity by about 1.5cc. what do u think about it

 

mate listen to us, the mhr rep is better than the corsa all round but the 21mm and stage 6 crank are a good idea.

 

oh ok then mhr rep it is then and wt about tht crank

 

like you said mate stage 6 would be a good choice or as dave said bgm pro evo

 

ok i am on scooter centre now is this all i need quick reply plz i am on checkout now

Bearing set BGM PRO incl. oil seals Minarelli 50cc Scooter

1x carb kit -POLINI- Dell Orto PHBG 21mm for Minarelli with horizon
1x Crankshaft bgm PRO EVOLUTION Minarelli 50cc horizontal 12mm
1x Zylinder 70cm³ Malossi -MHR REPLICA- Minarelli horizontal LC

is it a 12mm crank or 10 cheerz

 

id say definately a 21 mm dellorto and buy a new crank may aswell get it done all at once or else a few weeks days months down the line the crank will fuck up and ull be in the shit. it will do 140 with primary AND secondary gear up i imagine.
