porting

That's not right. Might have to tear it back down and check piston to wall clearance

 

[DUALSTROKE]

Check your squish. Curious to hear what that number comes back at.

well I was expectinv it to be a lil low because the dome is 23cc

 

[mud runner]

im really happy with the porting it pulls wheelies in 3rd gear now

 

[Blaaster]

What sprocket ratio are you running, and is your swing arm stock?

 

[mud runner]

I think it is 12 40 and yes it is stock

 

[Herpderplol]

12-40 ?? that would give you more low end right away, and less top speed

stock is 13-40

 

[mud runner]

use to it wouldent it would pull up in 2nd but not 3rd

What did you do to correct the issues you had before?

 

[mud runner]

when I sanded the dome in the head It raised the cc's and lowerd the compression

 

[Blaaster]

How much did you cut out of the dome?

 

[DUALSTROKE]

Sanded the dome and it made a difference? I am not buying it. You either sanded till your fingers fell off and changed the dome shape or one of my legs is longer than the other.

I sanded it down with 400 gritt till it was really smooth and I polished it till I could see myself in it heres a pic after 2 months of being on the bike

 

[Blaaster]

It looks like you sanded the squish out of that head!

 

[mud runner]

it looks the same as a stock one and I couldent tell a difference between this one and a stock head that wasent polished
