Agility 50 / Re: Factory Contra Spring?
« on: September 16, 2013, 01:28:04 PM »
Blue I originally had factory weight rollers of 7.5 gr. Take off was horriblely slow. Anther thing is I'm not sure I'm hitting power band rpm's right. That's why I went to lighter rollers! Which has helped connsideribly. BTW anyone know of a good cheap tach you can add onto a single cyl. application?
