Hi BHQ members. Decided to set up the degree wheel again to make sure it was zeroed in correctly and came up with the same figures.
Exhaust ports open at 84 deg ATDC
Transfer ports open at 122 deg ATDC ??
As for the port mapping, placed the barrels on a flat surface deck down( no head studs ). Cut paper to suit bore diameter, pushed down to be flush with deck and taped in place,then shaded over the ports.Removed paper and measured ports to deck.
As some said it would be pipey, and it is, it's all top end.
This motor was built for me by a builder in Australia for motor X years ago.Now I ride just for fun. Thats why I would like some stock barrels that havn't been played with and have them ported by a reputable builder in the US, to suit what ever combiation ,pipes,carbs stroke, etc I'd like to run.
It's great to be able to communicate with people that know more than me as the ATV market is tiny over here. Appreciate everybody's input and advice.
P.S Mopar1rules- Where did you get the computer software and what's it called?
