I have a 3.09:1 fist gear transmission, that coupled with 3.23 ring and pinion is about equivalent to a 3.73 gear. Not super deep, but not really tall either. The narrow LSA creates stronger pulses down low due to higher cylinder pressures.
Yes it does and I am a fan of tighter lsa's but it only goes so far if the gear ratio is not a good match kind of more of a fine tune in my opinion.but with 373 ratio should be good to go.
