Always a pleasure ya know?
Ive been doing the o-tuning thing for quite a while now: PX125,200, SS180, LD125 (my very first o-tuning as a teen), Several T5, some more I can't recollect (solex a very french passion!)... It became a second nature!
so let's get back to work and there is plenty left aside!!
Timing checked with moulte accuracy:
T:125°
E: 152°
to get 180° race-base (
http://www.race-base.com/2t-tools/steuerzeit/) says 7mm have to be removed at the upper edge of the exhaust port.
I'll stay <67% and get me a 45mm wide port
