Move sprocket or make jack shaft?

[Gokartoldfart]

Hey all just joined the page to get some help on me and my sons go kart build!, we bought a cheap rolling frame build a roll cage as well as some other metal fab but I need the axle sprocket to move about 6 inches over or to figure out a jack shaft , it’s got a 420 cc predator clone motor as well as a 40 series torque converter. What would be the suggestions of the group as I’m no go kart specialist ( I plan to mount motor much lower it’s just heavy af and easier to move back and forth to guesstimating what I should do here ) I’d like the Motor to sit center if possible and if I place it between shocks I cant get motor far enough over anyhow to align sprocket which is where it’s eventual home will be

That swing arm looks awfully short. Your driven is on backwards and needs to be turned around to function properly. That’s number 1. Slide the sprocket over to line up Also the axle sprocket should be a 60 tooth sprocket. 10 tooth sprocket should drive it along with all being #40.

Thank you for the imput I will rectify those issues

Slide the sprocket over to line up with what exactly??

That would be the driver gear on your torque converter.

Sweet done now that it is still misaligned with the rear axle sprocket should I move it over on the sprocket or should I come up with a jack shaft ??

Denny says slide the sprocket, the only reason you would need a jackshaft is if your rear sprocket is too small, how many teeth does it have? We’re looking for 60.

The axle sprocket hub is welded on. That needs to go away. Does the axle have a keyway along it's entire length?

There are 40 but I’m sure I could order a 60 teeth sprocket

Then make your own with a dremmel. I see now that you have a 40 series plate kit so you will have to leave your clutches as they are. Just make spacers to go between the small sprocket and clutch and bearings. You could just cheep out and buy a new axle. Be cheaper than a jackshaft and new bearings. Easier too!
Yes, you must have a 60 tooth axle sprocket!

I have a 1 inch shaft and bearings already if you think it might be cheaper to have the shaft keyed and buy a couple sprockets

Yes, you would be better off!
