Are there any ways to mod the stock carb for increased flow & performance.

I guess the title says it all.

I here of peeps boring out carbs on there banshees and 250r, so I would think it could be done to these carbs also but I don't think a stock or close to stock motor would benefit from it

You can bore the carb and shave the butterfly shaft to be slimmer and more airodynamic

 

['00 WO-YA!]

Hmm, the boring doesn't hardly sound worth the investment but maybe slimming the butterfly shaft, idk. I don't want to invest a dollar in this thing, wanna get my junk together & get myself an FCR but I thought if there were any free mods for it I'd give em a shot!

clicker spring instead of stock spring on the accel pump, little better throttle responce. there is a few threads about it

 

['00 WO-YA!]

Done, lol, as a matter of fact when I 1st pulled my carb apart it didn't even have a spring so the clicker spring became mandatory, haha!

The design of the stock carb is the problem. The best bet carb wise is to just upgrade the carb to an edel if you can get one or a z400 or a FCR carb.

FCR has my attention as you can prolly tell by my other thread but again, if there's anything that could be done with just a few tools & some time I'm game!

Remove the choke

 

['00 WO-YA!]

It has crossed my mind, I wonder if I can find any info on doing that?

 

[buzzy613]

no to jack the thread but i wonder if takin the butter fly valve out wil make more performance...

Remove the choke

How would that help preformance? I've heard before on car carbs that it does but don't understand how

 

[beastlywarrior228]

The choke disrupts air flow

 

[duneracerweston]

you could try taking the butterfly out but you would haveto leave the shaft because the accl pump and idel work off that shaft the choke on these has nothing to do with airflow there are 3 venturies in the motor side of the carb it idels off the big one and the choke is the other 3 so removing the choke is pointless on these

 

[yfmdeuce]

Any body fooled around with any porting or honeing of the carb to increase the diam and better the flow?

 

[beastlywarrior228]

Not worth it when you can just get a better carb

 

[duneracerweston]

I did it with my 38mm works ok not really worth the time and frustration tho get it right

 

['00 WO-YA!]

i might try to remove the butterfly just to see what happens.

 

[buzzy613]

any updates on removing the butterfly

 

['00 WO-YA!]
