Thanks a Bunch, I'll try those for now on the front.
Then work on the back.
I think I remember somebody modding the rear so the LT160's would fit, but I'll never find it again.

 

Hey guys lets be careful not to get Mr. Moore in trouble again, I 'd hate to have him gone again.
Hey also what size drill bit drill bit do you drill out the rollers with?

 

Did you get those pictures?

 

As long as I don't solicite, I'm in good shape. [img]i/expressions/face-icon-small-smile.gif[/img] But thanks.
We drill to get a certain weight. A generic answer would be a 5/16 bit, but many sizes have been used to get the roller weight where the motor wants it. ie:: 5/16-3/8- R-Q sized bits.
Tell me what your running now (rollers) and what you want to achieve and I'll see what drill size I'd recommend.[img]i/expressions/face-icon-small-smile.gif[/img]

For the topic starter,
If your rider is riding full throttle and bored, you need a motor.
If your child is far from that level but needs a lil more, Remove 2 of the rollers and have the head shaved .030. Lower the main jet to a 90 and go have fun.[img]i/expressions/face-icon-small-smile.gif[/img]
