yea tomorrow im stalling a 75cc kit wit a 20mm keihn carb, HRC Roller bearing cam, Uni pod air filter and kitaco rev box.... jus wondering if anyone out there has this set up? will i notice a gain? i also heard a 20mm carb is to big and that even 88 kits dont run 20s but 18s

 

well i gess u already bought the kit but look on twobros.com they have all sorts of **** ive riden allmost all the differnt 50s big bores i say go with 88cc superhead kit its the most reliable kit plus its a pretty big difference from sock youll can just throtle up a wheelie in 2nd

 

will you notice a gain fuknaright,,,,, you better be prepared for a **** load more torque....just ask swifty50 about his first ride on a big bore.....crash------------

 

well today i get my head back from the shop, they installed the cam n valve springs... so ill let u guys no how it performes when i install it

do u mind telling us swifty? lol

 

i have a 75,rev box, uni, stock carb half choke,and 15tooth sprocket and its realy "torquey" ~~~is that right??

i love it and everyone who rides my bike loves it a 88 with the big head is nice but for stuntin its overkill

my boy has one ported and polished and the frt wheel will come up easy all throttle at mid 3rd gear

if all you are doing is stuntin its perfect anything bigger than a 75cc and your putting to much money into your fiddy my opinion

 

holy **** :O.... my bike runs like a rocket :O:O:O but the thing i dont like is when im at a dead stop idling.... iwhen i jus full throttle it ... jus like crach it wide open it jus dies.... my stock 75 never did that :|:|

 

i recommend movistars setup to anyone that wants to modify their 50,i like to ride stock and have rode alot of different 50s,but his piece has torque out the *** and has a very smooth usable powerband,makes circles easy

 

tune yer carb brother

 

im thinking i might have to adjust the air fuel mixuter screw or maybe down size the jets? i dunno any ideas?

 

dyno tune that beotch you a big baller

 

i agree with fab
now you get to learn how to do jetting
and by the way if its cold today and hot tomorrow
tomorrow youll have to do it again

 

Which 75 kit do you have? I'm trying to decide which cc kit I want for my fiddy.

 

88 light bore stock carb air filter and pipe

best bang for your buck

 

Stock air filter and stock pipe too??

 

88s run 20 and 18 mm carbs,
20 will be too much with that 75, im thinking maybe you could get by with an 18

 

actualy i thot about it and for racing use a 16 or if you on street use an 18,

the 16's are on ebay all the time,
here is one

yup makes the most usable power for stunting

if you put a bigger carb just makes you go faster on top

 

Cool bro, I learn somethin new every day.

 

The carb should be fine, but it will be setup for more topend
