af18e spree vs af16 dio

[bakaracer]

thats because your friend has stock 12to1 gears

[bakaracer]

Do you think a 24mm Carb is big enough for my setup?

yeah its fine.

[bakaracer]

what exhaust are you using? what bore?

[kingkamehameha]

My spree didnt like lighter weights. Im running all 8.5s right now.

[fastplastic]

72cc to 125cc hmm maybe there would be a difference in weights

[fastplastic]

unless your port the crap out of the 82 the polini will always make more power... its just how it is...

[fastplastic]

looks like a v8 pipe good lil torque pipe.... just because the polini is 72cc doesnt mean 82cc is gonna be bigger faster better out of the box...

Your rollers weights might be too light. My friend has 50mm bore 28 carb pg long 9.1 gears and the 7g rollers are Way too light. The polini is going to rev higher than your bore. Your bore will be better off at a lower rpm. Try heavier weights.

If I am not mistaken that is a yms r1 pipe

[deuce217]

Have you checked out your spark plug? What is the gap? Nice wheels!

[fastplastic]

I belive you are correct

[Mystic]

those pipes come in 26mm or 28mm maybe bigger not sure

When i had my polini bore on the stock gears it pulled insanely hard for a scoot, but it was game over at 45mph. I never got sick of the acceleration though!

Then i put 8.44s in and it still pulls, but not as hard as before obviously.

Replaced my plug, ill check the gap when i get home. I think his just pulls so much harder cause of the gears. He's on stock gears right now. So is the r1 pipe any good? r1 sounds familiar now.

that pipe is fine. whats your jetting at? do you know if the boost port is matched to that bore?

[bakaracer]

I'm not sure about the porting. I'm running a 120 main and a 44 pilot. Pretty sure I'm too fat up top. I'm tempted to pull it apart and slap a poling kit on it. I don't know how it was broken in, or how the porting was done. Throttle response is awesome, its real snappy, it just seems like it should accelerate better. Accelerating at 2/3 throttle is the same as full throttle.

Have you done a plug chop? find out first if the block has been ported to match the bore your using before you buy a polini. yeah the 50-51mm bores are mainly more for mini stroke crank setups. there are some that is for stock stroke but most I see now are for mini stroke cranks.the only way to know if yours is for a stock stroke is do a port map of it. the numbers will tell.
