AJH clone large reed kit (basically a 70cc Gila) ported.
190* exhaust timing
gila size stock 2 petal with .030 cf reeds
Low comp head
mikuni tm24 flatslide
geared at 16x40 at the moment
derestricted shortened (3") estoril
timed at 17*
4j13 needle (also tried 5n13 and 4f10) on multiple settings
It wants to 4 stroke just before it hits pipe (around 30mph) no matter what needle/setting I've tried. If I tuck on flat ground it'll clear out and blast on the main jet. This thread has some good info, but it's not working for me. Maybe I need a leaner main and a powerjet setup or a lower hitting pipe? Ports stalling? Paging Mr. CWayne?
