Porting vs. reeds

[BGATZ]

have a couple of questions:

i have a 2004 blaster and i want to do some mods. i either want to port it or add vforce 3 reeds. right now the only motor mods i am running are a toomey b1 header and exhaust. i also have the airfilter from toomey on with the airbox lid removed. and the jet they provided in the package.

if i were going to port it, would it have to be rejeted? also would it be eaiser for the motor to blow?

for the vforce3 reeds ,would you need to rejet for that as well? also i have seen that you have to cut some part off, is that process tricky or does it bolt on with no modification?

whenever you do a modification where u are going to be giving the engine more/less air you need to rejet.. EVERY TIME. you cant compare reeds to porting, porting is by far the biggest gain you can do to these little motors. i say do both I:I I:I

For the reeds does something have to be modified for them to fit

for the vf3's yes i think you need to trim the back of the intake manifold. not hard to do at all. i think there is a diy on it somewhere

I'd do the porting , then reeds after that . Until you open up the ports and mAke them bigger it won't flow any more air/fuel .

Simply put...the power difference you felt from going from stock exhaust to Toomey will be a less drastic change in power than a port job (depending on port layout)...gitr ported. And yes rejet

Here is a link to the cutting of the reed cage, if you are using a normal intake manifold you will need to cut the crescent piece that extends into the reed cage
