[bansheeboi]

just want to know if you have you cylinders stroked and ported for t5's and down the line you change to cpi's would i have to go back and have them reported for those pipes or just rejet my carbs an im fine please enlightend me on this thanks

the bike will still run good with mismatched port/pipe combos but it will run better when it is setup up as a whole.

 

if you know you are going to get CPI's, port for CPI's. If you already setup for T5's, just throw some CPI's on there and re -jet.

X2. If your going to get CPI's just port for them. Not really sure what a difference it would make running a different pipe....

 

I had Wildcard port for my CPI's and it rips hard

here's how i feel about it...

 

you can run the same pipes on the "drag### port" that a cpi ported cylinder would use. the t-5's just wont rev as high as the cpi's and you will definatelly feel the brick wall effect the t-5's have in higher rpm's. BUT the t-5's will have a tad more lower end than the cpi's. the cpi's are much better suited for a high port number.. long time ago t-3's t-4's were set up on cylinders with a very very high port number (200 -205's) and they worked ok...

 

vice versa the cpi's wil also work ok with a lower port number thats suited for a t-5.. BUT the cpi will pull more rpm's with the same cylinders i just wish the cpi's fit better!! its all in really what you are wanting out of your motor. and be honest with yourself about how you ride it.
