really interesting, and looks almost stock in the execution. It's really interesting that he built a shortster engine combo - likely because the sporty unit construction setup wouldn't fit, but also to get that extra 5th gear.

Certainly nothing to criticize there, but a pair of 500cc British cylinders and heads would cap it off nicely. I’ve seen a 45 with Matchless barrels and heads.... interesting look to it. There is also a fellow around here that has a 45 with BMW Rennsport ? barrels and heads. I haven’t actually seen it, but should ask the guy if I can take a photo or two next time I see him.

harley 45 engines are flatheads and a completely different bottom case.

The setup I think is really interesting is ducati 2 valve desmo heads on top of big twins.

They make pleanty of beauty covers for sporty evo heads to make them look less "modern"

Divorced transmission sportsters (or shortsters - not to be confused with the harley monkey bike "shortster") are fascinating to me. The biggest flaw with ironheads and pre 1991 sportsters are the 4 speed transmissions. With pre 1978 ironehads you are also married to the awful large rear sprocket/drum brake setup stock, but that's a different conversation. those old 4 speeds have a ratio like an old muscle car (an m20 4 speed out of a 1966 chevelle to be exact - 2.52 1st and a 1:1 4th) which is a wide ratio and on the highway the bike ends up screaming. being able to run a norton or triumph transmission means a much closer ratio gearset to keep in the powerband, or you can find an overdrive trans like a baker

Ha! well would you look at that, somebody built a nicer Harley then H-D builds and they did it with old British bike parts, awesome!

... is a little sad because I think it is/was somebody's pride and joy.

45 is different yes, but don’t see anything that would prevent British thumper barrels of some sort going on there. I would think cylinder bolt pattern could be dealt with, but HD stuff is out of my wheelhouse. That Ducati one is interesting. Always thought it would fun to make something like that, but I’m already exhibiting enough odd behaviour to get folks thinking I should be institutionalized.

There is a thread out there on the engine with Matchless cylinders, but it’s all screwed up thanks to those twatts from photo bucket.


Trials.... back in the day, nobody ( in their right mind) shed a tear when an A10 got flung onto the scrap heap.

eh...I'm not so sure, I think if ti was possible or worth it, someone would have done it. Old Ironheads aren't bad in design, aside from the shared intake and valve angle, it's a hemi head and they flow pretty well stock with a lot of potential. I have seen guys like sputhe and robinson make ther own heads based on a stock/xr750 hybrid design, and lots of home builders convert to running 2 front heads do get dual carbs, but not a lot if any running brit heads on an iron or evo sporty.

Suprised you had the brass neck to post that Cyorg, with it not being another bloody CB.

Your scrap heap maybe, our scrap yards are full of Japanese bike parts.
Seen some nice ones at vintage rallies :cool: got to ride some, anything British pre-unit is interesting to me, no idea why, just is.

Well actually there is one reason showcased here nicely, you can easy hook any kind of motor up to it and have a cool bike.

While being worth it... if one was honest with ones self.. makes a good argument not to do it. Not that it matters, but pointless exercises aside, what is there about that engine that would make it that difficult? This is one reason why I choose to remain anonymous. There are folks around my neighbourhood that would drop off a set of Harley cases in the middle of the night just to screw with me.

This one is a WLA

All the time I spent in your part of the world and never heard that expression. Same with bell end... sorry not supposed to mention him.

While I confess there are a couple of Honda motorcycles that I wouldn’t mind owning.... that’s likely as far as it will ever get.
