Check everything over and go back to HSN .25 in from flush and LSN 1.5 in from flush.... Also you might like to remove the HSN needle and blow out the HSN needle seat.Let us know how you get on
Thanks, well in theory I sealed everything just before race, even made new o rings (Grizz style
), tank is quiet new, tried pressure test was ok...
Yes good idea, will check hsn seat.
If I put 6.5mm insert, will it affect much HSN settings or it will stay anyway at around .5 in?
Today we have bank holiday, so definitely afternoon will go to get that 5port back in life
P.S. Just got my new Grenade engine(99% 5port Go
) and grenade pipe, does somebody tried to compare grenade pipe VS 086, as I was happy with 086 , but maybe to give a try for grenade pipe, before I run in new engine?
