Re: How do I get started? I want to give it a try!

Jeremy, it was great meeting you yesterday. Jake asked me several times who's red car is that! Drop me an email or give me a call if we can help out. I do have used and new ones in stock as we discussed yesterday.

Thanks,
Mark

Re: Rotax question about RPM's after power band.

Alex, there could be several things that could cause this. The most common are jetting and gearing. By looking at your kart and the MyChron I can narrow it down and help you get over that "hump". Just give me a call if you'd like help and we can discuss the details.

Thanks,
Mark

Dick, I asked a few people and they said a 10x80...plus or minus a tooth should get you in the ball park.

Feel free to give me a call if you have any questions..

Thanks,
Mark

I would ask anyone that has an interest in Minimax and wants to voice their opinion, then show up and vote at the rules meeting Saturday! This is open to all club members.

I can go either way on the gearing, but having to change tires for rmax and club. NO FUN!

Guys the tire choice for NTK is ultimately up to the club. The tire choice is made at the rules meeting January 20th. Each tire manufacture offers the club a certain kick back for picking their tire as the “clubâ€

Guys I agree on the gearing and I think we can make it work at all the local tracks but Waco. The thing I don't want to really see is the Mojo tires. Jake and I tested Mojo's a month before Florida and ran them almost the entire time at NTK before the Nationals. For what ever reason the Mojo's just ...

Most important is to make sure your tire pressure isn't to low. I just looked at my notes and we bent those while practicing with Mojo's! You can also make or purchase a sprocket protector for the bottom of the chassis.

MINIMAX Gear change??**Please Read**

This is a poll to see what Minimax drivers and crews think about changing the spec gear at NTK. Currently the spec gear is a 12x80 and is in place to regulate the speed. Reasons to possibly change this gear. One is that all new rotax motors come with a 13t driver so there would be no need to purchas...
