ROOKY EVO RnR
I own a 1994 roadking 1340
it has 187000 miles, and began knocking.
I intend to rebuild it over this upcoming winter
Want to get power and lots of miles out of this rebuild.
I've rebuilt chevy 350 and lawn mower engines.
this will be my first motorcycle rebuild.
any and ALL suggestions and advice will be accepted and appreciated

If you can read a service manual and rebuild a Briggs engine it's not that hard. If you are looking for reliability and power leave it 80ci. Contact Scott at hillside cycle. He knows the engine well, does all the machine work needed, and can get you parts cheaper than I have found them anywhere else.
I should get my top end job back from him maybe tomorrow. He suspects I should be somewhere around 90hp and 95ftlbs.
Use good accurate torque wrenches and follow the tightening sequence the manual calls out.

With that many miles AND a knock, you're looking at a full lower end rebuild. I don't know what sort of equipment you have access to, but that goes beyond most garage shop capabilities.
Call Scott at Hillside and talk it over. He'll get you set up.

If the knock is a crankshaft bearing, rebuilding that is a skilled job. The main rod bearings can be honed and re-used with larger OD rollers, which is cheaper than new on the one hand, needs an expert on the other! Cylinder honing also needs special kit and a competent shop, so 0maha's advice is tops!

This is what I've learned when I tore my top end apart.
1.I bought a Cometic gasket kit for the top end and ended up using the base and head gaskets out of it. The Rocker gaskets were too stretched to fit in the grooves and I had to buy HD gaskets which fit perfectly.
2. Buy a good quality torque wrench.
3. I'd recommend buying the Rocker box wrench, it makes life easy.
4. Check your intake flanges and rocker covers for warping. Don't waste your money on the JP's Intake flanges if you have to replace.
5. Take your time putting the intake back together. I'm still fighting a vacuum leak.
6. Take your time assembling the Rockers. It's easy to knock the gaskets out of the grooves or not square them up and then you'll have an oil spray or leak. Either way, it sucks having to tear it apart again.
7. Assemble the Rocker Arms in the Rockers FIRST, before installing the rockers.
8. Pay close attention to how the push rod tubes come apart and go back together.
9. Get a good lift or jack and a comfy chair.
10. You'll need a 12pt socket for the head studs.
11. Take lots of pictures, take your time and enjoy. I did mine in a rush and wasn't happy about it. Neither was my back, see #9.
Watch plenty of Youtube videos. This one helped me a lot.
