upgrade carb tips?

[colescustom]

Have a bit of motor work done to my blaster, and looking to upgrade the carb. bored .20, ported, with some other goodies. I was thinking of porting the stock carb (26mm) or should i buy a larger one (28, 30mm etc)

I have tons of jets, and new carb kit with stock carb. And im able to do the work myself.

Should i work on the stocker? if not anyone in a smilar situation recomend a good upgrade?

The stock carburetor (Mikuni VM26) is a decent carburetor and a "regular" engine can be made to run decently on it but if you start to tune for more top end, it will run out of steam shortly....

A better "waste" of your time and energy would be to fit a larger carburetor on your engine. A PWK28, OKO 30, or larger bore Mikuni can fit into the stock intake boot and only requires a replacement throttle cable (the throttle cable "for TORS delete") and some work on the intake "snout".

Jetting help for Keihin is going to be more plentiful than jetting help for a Mikuni but Mikuni does make some decent carburetors.

The 30 would work good for a mild to mid modded motor.

id be wary of porting a stocker, you havnt got much material to work with. Go to a PWK 28

PE 28 is a 4 stroke carb

Crap.... will this still work on the blasty?

It can, but they're really finicky

Is it any better than running the stock carb? Finicky as in hard to jet?
