thanks for the reply weld..15 you rekon..I hoping to about 16-18 ish, some old tricks up my sleve..
all down to flow, ignition timing, and compression. 190Psi is where i want to be.
I port some big 4T motors over the years one was quite special. A VW 1.8L head from a golf GTi, standard 112BHP, on the rollers after stage 3, 139BHP.. and with the same cam!.. yup.. same cam.
If i can get the compression up a bit, looking at the head, that might be a bit of a problem,.. you never know.
anyways.. here are some pix of today..
engine out..
head off..
then some painting.. of the zorst
rack too
and rubbed down handle bars n repainted..
and the last pics.. of when i first saw it...
