1983 indy 600

Hey there I got a few questions about this 600 I picked up the other day. first off what is the fuel ratio to mix it at? what size carbs are supposed to be on it? I got this thing home found one of the crank case plugs in the bottom of the sled. so I ripped the fuel system off and had to rebuild the fuel pump. rebuilt the carbs adjusted them and everything. so put it all together started right up ran perfect. we took it out to a field to run it, and had a few good runs on it so then just tooling around a little bit and the motor locked up. what could have gone wrong?? my first assumption is that the oil mixture was wrong?

sounds like the motor siezed. i agree i think that motor should be oil injected. look for an oil reservior and make sure there was oil in it. probly gonna be a lost cause if it ran tight.

IT has a hole down on the bottom of the block where the pump looks like it would go like on my 94 600 but it doesnt look like there are spots for bolts and I put my finger in it and it feels like it is just a dead end I cant feel anything in the hole. there was no resevor either but I think it has been around a while so who knows what someone did. I dont see any evedence of oil injection anywhere but it could of all been taken off I guess. why would someone do that??

I guess some people make an oil injected sled pre mix just to have assurance that the oil pump wont doesnt go out and their motor dont blow up.

I have done some more research and this motor is not oil injected. so that being known it should have been good unless i mixed the gas wrong right? does anyone know what the ratio should be.

I would run it more rich than lean. 50:1 doesnt have that much oil and i would run more of a 40:1 mixture. Thats my opinion though, if i had a premix sled, id rather have it run a little more rich than lean.

id go about 35:1 till you start fouling plugs then start running leaner like 40:1. Plugs are much easier to swap than if you start off to lean and blow the motor
