Springzilla Verdict. 1979 AMF Harley-Davidson XLH1000 Ironhead Sportster

The beast has been unleashed! Every single foot pound of torque that little engine can muster now hits the road as God intended. You need fingers like an English bowman at Agincourt to operate the clutch, and it drags like a bastard so get in neutral before you come to a halt and you should be fine.

I've read that people that tried the single spring would switch back. Now a satisfied owner to start the day on a positive note. Happy it worked for you.

Everyone's different, but I hate it when the clutch can't keep up with the engine. It pulls like a train now, and I can live with the drag. There's no drain for the gearbox oil if I went to a dry single plate clutch, so it would mean stripping down to the bare crankcases again to drill and tap one. Don't fancy that right now; it always takes way longer than it should.

@@ImminghamIronhead You probably didn't buy it to practice disassembly and assembly, you seemingly have enough practice doing that. If the new spring works I would tend to call it good. Besides if you are right handed it will build your left forearm to match. ☺ My sporty got set aside while I tend to a problem on the panhead and they are both waiting for warmer weather. I got old and don't willingly funtion below 50 degrees Fahrenheit. Keep up the good work, you are an inspiration and I learn from your travails, thank you.
