Re: Gear Ratio with Predator 212cc and jackshaft
It's not so much the torque of the engine. I have a Honda 196 that I run with a TAV-2 transmission and a 50t sprocket. That's an overall starting ratio of 1:13.4. Yes, geared higher than tiny engines, but still reasonable for smooth takeoff. I would say that a 1:5 ratio would probably cook the clutch quickly. It's like being able to take off in third gear. Yeah, it's possible. Yes, you can get a higher top speed in 3rd, but you risk burning out the clutch if you use it to start. Doesn't matter if you drive a Viper or a Civic.
Never stop wrenching
