here are some pictures of my 81 srx that is almost finished. it has a freshly rebuild motor in it with all new gaskets, new cylinders, pistons, piston rings, brand new oil pump and new carbs and all new fuel line. i also polished the ports in the cylinders and also polished the manifolds. so here are some of the pics that i took.
i will put more up when its all finished.

The Prefix Number RT499 on the Cover. Or if you name it as Pump Drive - Gear indicate the 499cc 8R9 SRX 500 Motor.
as Chrisrider63 told you be careful with the SRX Crank. Very Very hard to find spare parts for it if you blow it up

No that RT499 bottom end is a rare collectors item and i would not be using it as only there are 15 srx 500's out there and only a few people from this site have one.

It is worth what someone is willing to pay. I am sure there was a time that it was worth $2000+ Given that those machines have gone for $10,000+ with an original engine.
Someone with more knowledge with the SRX 500 may know what todays prices would / could bring. I know that i wouldnt run it in anything unless it was in a SRX 500 chassis. Lower ends and cases for the 440 and 540 are easy to find. It would probably be best to preserve that bad boy.
