Porting!

while we are on the topic of porting thought I should ask what grinding / cutting bits most of you guys use?

I decided it was time to start to play with porting stuff the other day and opened up, cleaned and partially smoothed a alloy intake manifold the other day and put some decent wear on my grinding stones (Silicon Carbide stones I think). I am looking at buying some more gear but am unsure if I should get more of these stones as they worked fairly well but just wore out quicker then I had hoped or if something like Carbide Burs Cutting Tools
would be much better suited and should last.

I have used normal carbide burs before and they do tend to clog up fairly easily with alloy but a quick once over with a wire wheel and they are like new again.

yer it would be but i never use and BVH cos they no good on an 125 and gives less performance so dont get to court up in the moment

and im sure of this cos flow benchers are more right the mack in his shed wif his die grinder

If you have a dremel get the 60 grit sanding rolls. They'll chew through alloy very fast and leave the finish you want. Save the stones only for grinding down the steel guides.

fair enough
how do you normally go about going around bends like in intake manifolds? The straight bit was easy.. but the bend was a bit more of a challenge to get it down how I wanted it. Wasn't helpful to find out that the manifold didn't even fit in the end..... ohh well needed the experience

So u droped 5k on daytona head hoping and wood flow less so you can build big HP 125???
I'm confussed...I got all rong, I better stop wif 30/24 valve Lifan heds....

the sanding roll will just easy go round the bend you will see. Finish the bend by hand to make perfect. You will feel imperfections easily with your finger.

i did this befor i got mi 119cc and the only reason i didnt use an BVH was becase there no good in and 125cc motor. '

also i didnt make and high HP BVH motor was because i race in an 125cc class and wat the point in cheating it jst no fun....

yer u mustav misundastand me cause wot i say is ...u sayd big flow no gud on 125, but u put daytona on ...confussed mor now

hahahahhahaha
I absolutely pissed myself reading that Mack
I could never really understand Corey and most of the time just guessed what he was saying, but don't tell me you are going the same way, who will I turn to for help now?

they daytona can handle more air it run an 14:1 comprestion ratio and the values in it are not big at all i thin they like 21/19 not sure but.

and the first thing c'mon man u cant compare an $10000 jap motor built for racing only to an $300 ish motor use for evey day life
