Jim, fwiw I received an order from Frame Crafters for a set of pipes on a H1R with reversed cylinders. He was planning on modding an existing kit of mine but I was thinking I might be able to nip 2 in the bud. I'm confident I can make a design that works well on both motors. I thought you'd appreciate these shots of his project. Interesting frame but a long shot from an H1r.
I will be trying to get my pipes to look similar to the shape of header pipes used on the original H2r. (see below)This is North's H1r frame.H2r header pipes shown here with the steep angle near the exhaust ports then strait down and then close to the frame to leave room for the full fairing.

The pipe layout makes sense Jim.
Also, he never claimed it was a replica, just that a H1 was going in it... Actually, his design looks more efficient than the H1R side by side. I should ask him about the weight of it.

If I was doing a custom frame I wouldn't bother with reverse cylinders. It's a lot of extra work. Like 860's project with Dennis's frame. Looks great and all custom. No replica look there.

Are you referring to the down tubes just aft of the steering head? If so, this is the part I like about the frame, they shorten the backbone and will help quite a bit actually.

I'm referring to the engine cradle down tubes. They can be made to fit the stock cylinder configuration or if it's to be "similar" to a H1r or H2r the outer cylinders must be reversed as you know. 860 choose to use the version of Dennis's frame that fits a stock engine and saved himself a lot of work on the cylinders. What I was saying is I simply don't see why you would build a frame that requires the cylinder reversal if it were not meant to look like a H1r or an H2r. There are several proven race frames out there that do not require the reversed cylinder configuration. LittleGuys is a good example where he used a frame built by Lou Zeman and again no exra work to reverse the cylinders.

I can't answer that anymore than why someone would make a HR replica without reversing the cylinders? Maybe just to make a more rigid frame and cool factor? He does make custom frames for a living.

Here's an update on the H2r. This is where it is now. Still a lot to do but it's on hold till I get the work done at my house and time to setup a workshop.
