I have some notes for a track we use to run flat heads on and trying for figure out how much I need to go up on the clutch for a clone.
Your asking how much bigger front driver ?I have some notes for a track we use to run flat heads on and trying for figure out how much I need to go up on the clutch for a clone.
You might be correct Al but I think he's asking about gearing comparison.I think most would agree, the clutch stall RPM, on any engine, on any track should be set to the engines peak torque RPM.
Something you might try; place an analog bathroom scale between the front of your kart and a strong wall. The clutch stall RPM that produces the highest readings would be best.
Yea we ran a 14-63 on flathead and I was thinking a 15-63 for clone. I may have to change the clutch when I get there but I’m trying to get a starting point. Haven’t ran there in 20 years and just got back in to Karting in January and none of my gear notes have been helpful.Your asking how much bigger front driver ?
What was your flathead gearing ?
Do you know track size ?
Most always 1 bigger your thinking correct should put you real close to start provided your close on tires as well.Yea we ran a 14-63 on flathead and I was thinking a 15-63 for clone.
