I bought a 1980 1100E for next to nothing back in December. Among other things, it was missing the carbs, airbox, and the title. The fella that I bought if from hadn't done any work on it, and he didn't have the title. So using the resources and suggestions on this site, along with the factory service manual, I got her running by March and was riding around by May.
Around the time that I first fired her up, I was able to track down the title holder and got the title so the bike could be registered in my name. This previous owner told me that the bike was his "go-fast, hot-rod" and it was built with a bunch of performance parts. He also told me the reason that the carbs were missing when I bought it was because he had some smoothbores for it that he had pulled just before he got rid of the bike, and he offered to sell those to me on the spot. I declined the offer for the carbs, got the title, and left.
I've ridden this bike around for probably 500 miles on a set of stock BS34SS carbs that I bought and refurbished from a member on this site. I am also running a stock airbox, which I bought from another member. The exhaust is a badass 4-1 with a Kerker K2 muffler. This exhaust came with the bike when I bought it. I get a mist of oil from the valve cover gasket when I am going much faster than highway speed. Also, the shift return spring needs some attention because I have to slip my toe under the shifter just before downshifting. So I decided to pull the engine and address these issues while also checking out the internals of the engine.
The obvious go-fast parts, external to the engine, are:
the 4-1 header and Kerker K2 muffler
3 ohm green Dyna coils
Lockhart oil cooler
Now onto the engine. I need some help identifying some of these parts, so I took lots of pictures. The cams appear to be Megacycle drag race profile cams. 6 dot 3 and 8520 are stamped right up next to the sprocket on both exhaust and intake cams. This matches up with the 385-20 part number, which is a hardfaced cam with .390 lift and 252 degress of duration.
The sprockets are the stock ones but the intake sprocket kinda looks like it has been slightly slotted.
Here is the intake cam:
And here is the exhaust cam:
With a rocker ratio of 1.52, the intake lift is (1.380-1.124)*1.52=0.389 inches, right? And so then exhaust lift is (1.372-1.116)*1.52=0.389 inches.
Here's a pic of the cam chain. DID 219 FTS endless chain. Is this stock or HD?
Valves are stock diameter - 23 mm exhaust and 27 mm intake. I pulled two intake valves and the heads are worn. I unfortunately did not snap any pictures.
