We’ve been running that combo and a 650 for the last 13 or more years..
Just freshened the 650 three weeks ago with new carbs. Found 16 foot lbs, probably 18 hp or more and it picked up vacume too.
We have a baseline pull 5800 to 7500. All gains show up without pulling to peak..8300.
Can’t wait to bolt those carbs on the 637.
Nice little find!  How long will you have to wait to test it on the track?
