Joe, personal opinion here, but, I don't trust plug color on today's pump gas for anything other then maybe long range overall condition, to many additives in pump gas. I have many times seen EGT numbers reading low 800-1000, which usually would say Rich, but actually was too lean. I've seen this mo...

I'm not sure which SD pistons he used, Haven't had a chance to find him yet, but I will. I know ARIES, Wisco and J&E have made custom pistons for karting, not always cheap but its not really hard for them to make and they will do it. I just need time to tear a few things apart here and measure. ...

I have dealt with LA sleeve before, good guys. I haven't measured the sleeve I have yet nor have I tracked down Perry to see exactly which piston he used.. Need to get past the opening of the kart season here first. Were supppose to be in Savannah Ga this weekend for a race, but, the first 4 weeks i...

Thanks guys We have a sunnen hone, a mill, and lathe,ect but build small racing 4 strokes for a living, been quite a while since I've done big sled engines. Mostly I was wondering what came stock, I see now what I have didn't. Many years ago, when we raced I had a friend that raced these engines He ...

Bought a '83 several months ago. Seller said he had new cyls and pistons installed but couldn't get it to run.. Looking threw the plug hole and ex port, this appeared to be true. Both sides pulled 150 psi. Cleaned carbs and got it to run, with in 3 min. idling I heard it start to loose power. Look u...

Your killin me Joe, been bike riding for a month................. not by choice

Wow, I guess Jeff types much faster then me

It might make it easier to understand if you relate your sled to a car. The clutches are the transmission 3,4,5,6, speed. The gears are like the rear end, a completely different thing. Our clutches don't have gears, but are constantly variable going from a low to a high and some overdrive. Gears wil...

Once again, thanks for the help. Bob

Is there any place I can find spec'sfor these engines? I have 1to 1 1/2 th on the side that scuffed and 2 - 3 th on the other side. Does anyone know what it calls for on piston to wall for these engines?

They do make a rectifier, many old sleds had them to charge batterys or I think its a standard elec shop item. Mine actually came off my 71 Evinrude. Its about 1 in sq, and 1/2 thick, 4 wires hook to it, 2, 12v ac and a + and - 12 v dc come out. I use it on my '81 SRV to power a neon light which doe...
