The pipe was designed to give a wider range but at a slightly higher rpm again.
This may in fact not be possible with the transfer geometry it has, and it may need to be lengthened a little to put it back in synch with the porting.
The timings are spot on, but for sure the scavenging regime isnt a RSA copy.
The belly starts at 66% of TL, but has 3 sections of bend within it - and another at the junction of the rear cone - that is why it looks that way, I was copying the centreline shape of a pressed pipe..
Every pipe is timing critical, this design is no more or less sensitive in that it will need the retard slope moving to the right if it forces the peak power up a few rpm.
Ive got a thing thats unique and new.To prove it I'll have the last laugh on you.Cause instead of one head I got two.And you know two heads are better than one.
