In my efforts to find a speed sprocket for my sons Arctic cat 90 I found that arctic cat actually has a speed sprocket it is a 44 tooth part number is 3301-497 the pitch on the chain is 428 stock, I can get a 30 series sproket from Rebel gears, I was also told that the predator hub assemble will bolt in place to utilize those gears also.

When you say semper fi and it says your from Jacksonville I would assume your stationed at either Lejeune or New River. If I am correct do you race at any of the local motocross tracks in the area.

 

Jacksonville Florida. we ride in Ocala national forest, GNCC at gainsville, and palatka. North Florida Motorcross track in Hilliard

 

OK wrong Jacksonville, I was thinking of the one in North Carolina.
