Cylinders exhuast port size ?

Does the size of the exhuast port effect my performace as my port hole is very small compared to my mates as i have a cheap 50 cylinder unlike them who have an original one. My speeds are alot slower yet i have more upgrades? I was just wondering if the exhuast port size effected performace?

 

alright mate as said in the other thread them cheap 50cc cylinders are very badly made and have a poor port layout and yes the exhaust port will make a difference but in all honesty your better off getting a yamaha/doppler/malossi/polini cylinder

 

ok thanks i thought it might and i am looking to buy the doppler s1f cylinder or maybe the airsal aluminium 50. Which one do you think is the better buy?

 

give me the links for both and i can have a look for you

i recommened the doppler 1 for the good price and the reliability remeber though if you buy it to run in properly afterall its cast iron

 

ok thanks alot this should sort my problems out and ill get back to you when its hooked up

 

Might aswell get a 70kit?? A polini sport 70 costs what.. 5 maybe 10 quid more than one of those souped up 50 kits, and much more powerful.

 

my dad wont let me even though my bike is ilegal for my age already and he lets that, he just wont let me break the 50cc 16 year old limit :cry: :L

 

Then dont let daddy know?? An aftermarket 50cc kit is still Illegal!!　So you might aswell just get a 70kit fitted!

 

:L you really think if i could i wouldnt get a 70 ? of corse i would .. i have a brother who would tell him stright away -.-

 

beat him up that'll keep his gob shut !
