Ironhead Wanna build a cheap big bore stroker ?

[Ferrous Head]

The PB cams are going to make it a bear to kick start.

They are great for stock 900's. But stroking the engine to 4 5/8 ths will push your compression ratio up a long way.

I would look for a set with much later closing inlet if you can.

Unless you live on a big hill ?

LOL my right leg is actually 4 times the size of my left...

My Ebay bike has both electric and kick start now. No hills but I had a set of rollers once, might invest in another one.

I kind of like the PB cams so I'll retain them for the initial build and see where to go from there.

The "Training" program is a waste of time & money.
And always leaves you "wanting".

Build it right the first time and enjoy lots of miles.
If you build it right it will be very difficult to wear out.

I would dual plug it before installing a stroker crank, that is your best bang for the buck.

Their actually just shy of .300 taller those pistons would be way down in the hole. Some 5 inch wheels would be about. What you'd need

I prefer to call it tinkering as opposed to training. I have multiple bikes so I've always got one to ride. I wrenched for Harley Davidson of San Antonio Texas back in the 70's, and during my Naval career I wrenched at shops in Mayport, Florida and Norfolk Virginia. The single most significant improvement you can do for an Ironhead is stroke.

Some people seem to shy away from doing any work on their engines the same way I shay away from a brown snake.

But they are pretty simple engines. And if you know what your doing (meaning you've done it before) then you know pretty much what's involved and it doesn't really take that much time or effort.

Changing cams on these engines is not a big job.

But I will tell you my brother had a big gore stroker back in about 1962. I used to help him push start it simply because there was no other way to get it running. He used to bet people $5 they couldn't kick start it. He always won the money. Poor old Greg Hoffman, a big fat pig of a man who rode a Panhead was the last one to try. He walked on crutches for weeks after that and I laughed cause I hated the guy.

I do agree about dual plugs, they help a lot. And Morris is now selling mag caps already setup for the dual leads. I run duel plugs single fire but that's kind of expensive.

lol, poor guy with a 7 to 1 compression panhead learned the hard way about Sportsters.

As for dual plugs I'm not impressed. If I were trying to get a fraction of a second off my time maybe, if I were concerned about fuel economy or emissions maybe. I ran a 93ci Shovelhead set up with dual plugs and Dyna S single fire. Bike had 12 to 1 compression and was a beast, dual plugs helped with getting it started reliably.

I enjoy wrenching. I'll change cams just to look at them.

The dual plugs and single fire only go on my race engines. I am looking for everything I can get. Plus I love the way it idles in the pits.

My 66 CH on the other hand sounds just like my poor old corvette when a vacuum line has fallen off.

I spend many, many, many hours in my workshop every day.

Mind you, I'm only doing a ten minute job.

But I'm old and blind so I do have an excuse.
