Trying to Oval Race a 1987 Phazer. The tracks are about 3/16 of a
mile. Pretty short runs in the straight aways. I would like to gear
down from the std 17/29. Several people running exciters have said
they run 15/31 or 16/33.
Do you think I will need to change my primary spring? Softer or stronger?
I am wondering if you can suggest a list of primary clutch springs that I
should trial?
The exciters are running 7000 rpm peak. Is that where the Phazer should run too?
