Indian Hendee 4 valve boardtrack racer. Most overhead valve Indians were 8 valve motors but a few were 4 valve OHV
I just purchased this 4 valve top end set and plan on using them on the Hendee Belle motor.
An 8-valve Indian was a very fast bike for the early 1900's but I have spoken to several people who have ridden them and the 4 valve bikes are pretty quick as well.
Think about it...a minimum frame, no brakes, no clutch and no throttle. You set the throttle at the beginning of the race and slowed using the kill switch or retard the magneto. Pretty hairy stuff....
