i have a 114 kit and 18" and 19" tires what is a good setup for hare scrambles or mx we do both but more woods riding

I would go up a tooth on the counter sprocket with the 18 inch tire, thats what I did with just a slip-on and a small bumpstick and the engine pulls it fine, not sure about a 19 inch tire but its worth a try with the extra CC's, Steve

18" snowhogs or true 18" tires. Snowhogs are not true to size. We usually ran a 14/48 combo with a good running 114cc. 14/50 will give ya some more torque but 14/48 seemed to be good for us, enough torque but yet more top end too. We ran rears that were closer to a true 18" diameter

[atvnmark]

yes there true 18"rear and 19" on the front.

We ran an 06 TRX in hare scrambles with a 14/48 114CC Kit.Once we went to a 125CC kit we switched to 15/48. Pick your longest straight and gear it for that. We were limited to using the centrifical clutch due to rule restrictions so I can not help you there.
