1999 Sporty Chop/Cut/Rebuild
It was a 1999 HD Sportster 1200 Custom, but not anymore
When I get done with it you'll have a hard time figuring out what it was and it should have about twice the HP & Torque

more pics
I found an old school peanut tank for it and a fat bob fender. Now I'm working on getting rid of the chrome, rust and dirt.
The cylinders were so outta round from the factory that the rings never seated and most all of the original cross hatch is still visible even after 13,000 miles! I'll be selling those 1200 P/Cs off and replacing with a nice set of aftermkt 1250 jugs.

Not a lot of fund to ride as it was set up, but when I'm done cutting it up it will weigh about 100lbs less and have ported heads, bigger valves, bigger pistons, bigger cylinders, bigger cams and a new ignition. Shooting for about 100HP and 90Ft-Lbs of torque

Good luck. I have a friend who raced a Harley-powered Buell (XB9?) and he told me he spent about 100 hrs on the heads alone (welding, cutting,....). While he did eventually get some semi-decent power out of it, reliability went down the tube.
You may want to look at getting some Buell heads for it as apparently they are different and much more efficient (as a starting point).

As far as reliability they should be bullet proof with new OS stainless valves, high performance springs, titanium retainers, 10 degree locks, and bronze manganese valve guides.

Keep us in the loop bud
Sounds interesting.
P.S. While I must admit to despising most everything Harley builds or has ever built, I have a real sweet spot for the XR1200 (put an engine like the one you`re building in it and woohoo!!!!)

At least one of those pieces of junk will be no more.
I love harleys, if I could afford one I would have one. My cousin builds early 1900s board track racers for Fred Lange (google it), that is the kind of Harley I would give both ********* for. That said, I despise sportsters with a passion. The ironhead was a damn joke, I don't know why people even like them other than they are affordable.
Keep us updated, custom projects rule.

Crankshaft run out & end play
End play & run out are well within spec, so I'll split the cases tonight and give everything a good cleaning and relubing and start putting this puzzle back together

Peanut Tank Painted
I laid the base color on the tank and it looks pretty good. It's a Porsche paint called Grand Prix White from 1981. I like the fact that the white is not real bright. I had no idea how it would turn out, but it will work well as part of the old school Martini Racing color scheme and the theme for this build.

New Mikuni HSR42 Flatside
Well looky what came in the mail today
I'm replacing that old tired 13 year old stock CV40 carb with a big dawg that will get me over 100hp...yep you heard me right that's 100hp on a Sportster, but that's not where the fun is...the fun will be the 90 Ft-Lb of torque

That style of bike is what I'm making over the winter time, but with a Superhawk engine. I purchased the engine and wire harness about a week ago. Should be a fun project, and the wife will ride on the back of it. She simply does NOT want to ride bitch on my Superhawk, so that reason is a great reason to build a Superhawk chopper!

Looks awesome have you figured what you'll be running for exhaust yet? I've always loved the xr style high pipes supertrapp makes but I don't know if they'd go with your bike. Anyway looks great.

Honestly man might be the path I take next, woman left me about a month ago, and sold the superhawk to a new forum member on here, he's all spun up and reading, but waiting on my new job to start so working construction right now. Has me getting better with my hands and thinking I may go with the same type of build as you. If I do it I'll put it on here as well
