I’m looking at an 11 Arrow AX9, but I have a concern. Seller told me the guy he bought it from cut out the third bearing on the rear axle to mount the motor. Is this common? Seems like a big red flag but I wanted to get an opinion from some people running the class. TIA!
Arrow does not supply a bearing or cassette for the 3rd bearing on 4 cycle AX 9″s. I recently refurbished an AX9 4s and removed the third bearing mount and a few other pieces I knew I wouldn’t need on the kart from my previous experience with this model. My all time favorite kart by the way!
There are some chassis that have a 3rd axle bearing and welded on seat struts that are really hard to mount a LO 206 on. Often times they have welded on seat struts that get in the way of the clutch and chain. Removing this seat strut and replacing it with a bolt on strut usually solves the problem. In fact removing the other seat strut makes your life a whole lot simpler since you can now put the seat wherever you need to to get the motor clearance and weight distribution.
I bought an Arrow AX09 from KartSport last August with a LO206 on board. They used a jackshaft to get things right without cutting things up. The third bearing is held in place with zip ties so it can run loose. It has worked very well for my son running LO206 Jr ( Gold slide ) at Gopro as well as Carolina Motorsports Park.
No offense Pat but keep in mind that adding additional shafts and chain consumes horsepower. Personally, that’s not something i would want to do with a LO 206. In my opinion jackshafts are also kind of pricy.
