Hej Lars! Så skulle du jo have købt det J topstykke jeg havde liggende der passer på de gamle 900/1000'ere ;)

But, isn't the PSP Stage 1 porting still with the standard size valves ? With the 1426cc kit don't you need bigger valves or another head to use all of its potential ?

They only way to get full use of 1428cc and Z1 style head is Turbo I have a few 1428s out with full blown Z1 style heads you just cannot feed it the air it wants.
1984 750 Turbo

Is there a link for a thread of your original build? Looks like a nice bike.
