25ml carb help!!! Please

Hi all i have a 172 runner currently which has a 25ml carb. i know the bike is not running as good as it could i have played around with the jets etc :msn1: but i still no it could push more out of the carb then what it is at the moment.

Please if anyone could help or even give me there set up so i have a rough idea of which set up i should be goin with i.e needle atomiser pilot jet??

I am running a 108 atm with a 266 atomiser 45 pilot 2nd cup from top on a m30 needle but i know it can push more. please reply guys imp:

Cheers all Dan :beer:

 

not sure bout the atomiser never known any 1 to bother changing it but ive heard mainly people using 105 main jet 55 pilot jet and needle clip at the top

 

Thanks for that. I'll give it a shot tomorrow in the morning when its light outside. Anyone else with any advice is welcome to post imp: Cheers

 

What shall i do PM you?? Cheers Dan

 

Ok then no problem here is the list of things... I have a 172 bore 25ml carb polini evo reed block polini manifold malossi variator 13.5 g rollers polini clutch and clutch bell BGM EVO 52 crank and a KB Racing billet head.

Thanks for all the help :beer:

 

Alright then so what your saying is i need to use 2 base gasgets rather than one am i correct there? Which will higher the exhaust port a little as you said making the mixture burn more better than what it is at the moment. As for the rollers jetting i will be doing this one at a time and not changing loads of bits all at once.


Thanks for all your help Minor

looooool

 

lol ur funny

yh when im ready to post pics i will my bike aint done yet wait for the finished artical if you dont wanna help m8 thats cool what your not willin to do sum 1 else will

 

Re: lol your funny

'read all above posts' - he explains what is a good setup to start working around, no-one can tell you the right setup, it is purely dependant on the bike

 

Yeah the runner is going well at the moment.
I also forgot to say that i have changed the original slide (30) for a (40) slide as the cutaway area was larger than the 30 there for it will let more air in.
And that i have a airfilter on it aswel.

Cheers
