    In the meantime, my mini sub project to make a replica swingarm in alloy is making slow progress....

    The alloy swing arm is progressing surprisingly well (touch wood).... 15 hours of machining so far, and this is how its looking.

    Harley parts aren't known for being lightweight, and sure enough the original swing arm of my aftermarket chassis weighs a hefty 34lbs. My target is to half that with this new alloy copy, so far with all components it weighs 20lbs, but there's still a pound or two to lose, so the target is possible. 17lbs is still a boat anchor in sports bike terms but its better than 34lbs.

    Note the 'V' shaped grooves machined into the arm where two pieces are bolted together. This is where its going to be welded, as the groove allows for a neater stronger weld.

    You may wish to visit the ecosse site. http://ecossemoto.com/ definitely motorcycle porn.
    For a small fortune, you too, can have a titanium frame, ohlins goodies and etc, on your Harley with a Patrick Racing engine.

    I've seen those before, doubt they've sold many. I prefer the French Avinton models..

    Nice!
    But, not so sure about the draw through system

    I think the turbo is a one off, I didn't see it offered on their website.

    The new electrics are now all done, must say I'm impressed with the Moto Gadget components, despite the expense. The workshop charged me £1065 for the work, though more than £600 was for parts, which isn't too bad. With the changes to the swing arm (£140 for welding and powder coating) and another £140 for the new Speedo/tacho, in total all the mods came in at £1445, which is a bit less than I expected.

    Now just waiting for the spring to arrive to get some miles under its wheels. In the meantime my never ending Guzzi project is going to have the same Moto Gadget M Unit and switchgear fitted soon.

    The alloy swing arm is making good progress, with the adjuster slots now milled into the two spars, and some weight lost by milling out the inside of those spars. Next is to make the axle adjusters, then the various pieces which are just bolted together can be welded together. A quick guestimate says it should end up weighing a bit less than half the steel original (17 lbs Vs 34lbs)

    Good and interesting thread. Didnt ever think i would be interested in a 'Harley' type build, but i like this one.

    Since I rode the bike home, the weather has been awful here.. snow, ice and high winds... probably my fault lol.. So haven't been out on it yet. But here's the last video I made at the workshop when the electrical work was completed..




    While here's a potential new project to keep me occupied once all my other project bikes are finished..

    17lbs is a nice slice of lard to shave off a bike money spent reducing weight is always a good investment .:-)

    yep and I could lose another 10 lbs or more by switching to a Li Ion battery, which I may well do at some point.

    While this isn't one of my never ending projects, its my mates, but I did have a small part in the project, so that's my excuse to mention it.. A 1991 XL883 with a few mods... including different wheels, forks (revalved GSXR600 with KTech internals), one off yokes, oil tank, bodywork (which has just come back from the painter), Metchamex swing arm, Hydraulic clutch, VFR controls etc etc. Its taken a long time, but should be up and running and on the Dyno next week.. oh it also has a 1250 conversion with flowed and big valve heads..

    That's some very interesting and beautiful work. Oh to have access to the machine shop... and the skill and creativity to make it useful <sigh>.

    To be fair any tricky machining I leave to my mate, I have plenty of imagination but not so much skill.. However, a few weeks ago I helped another mate track down a nice Evo Sportster that he's been wanting for ages. Its surprisingly original, with one owner from new and 13,000 miles on the clock. I'm surprised how much these sportsters go for these days, it doesn't seem that long ago when a tidy early 883 would be worth around £1500 to £2000 (the last one I found five years ago was bought for £1500)... but not anymore, even really rough ones that need work go for more than £2000, while this wasn't over priced at £3000...

    Oh and the GS1000S is also my mates too, he's owned it for years, though he doesn't ride much anymore, as he's too busy working and prefers golf on his rare days off.

    Which may make you wonder why he's bought a XL883 when he hardly ever rides anymore.. And that's where things get interesting..

    The bikes are parked up in my mates engineering workshop, where he has CNC lathes and millers as well as some good old fashioned manual kit. So he can pretty much machine anything he wants, and what he wants is a Harley flat track replica. Now there are plenty of Sportsters out there with look of a flat tracker, a seat unit mostly, but they aren't really a true replica, which is what my mate wants to build. This means a lightweight chrome moly frame, but also XR style twin carbed heads. That is heads with individual carbs as per the real XR750. With the older Ironhead engines its fairly easy to play around with the heads by fitting a front head on the rear cylinder, there are a few variations, or indeed fitted real XR heads.. if you can find them.

    But fitting XR style heads to an evo isn't so easy, and I cant recall seeing it done. Anyway my mate intends to make a pair of heads for his evo, and unlike most of us amateurs he may well be able to do it. One of his customers builds racing E type jags, which my mate does the head work for, he reckons the E type and XL heads are very similar. The only thing that may get in the way is lack of time, as he so busy. But we'll see..

    Ah yes Sundance, I remember they made a black and gold race bike called something like 'Daytona Weapon' to race at Daytona a few years ago. In the links I cant see where they sell the heads as a kit? I assumed they only sell complete bikes... ? And if they do sell their heads as a kit, I suspect they'd be very expensive. Besides making stuff is all part of the fun. If my mate succeeds, I've already told him I want a pair too..

    He'll surely do pristine work on his project, but his final results would be beautiful even if starting with a rougher Sportster. There are so few unmolested original Sportsters in that condition - it's a shame to use that one for a project.

    I agree, he originally just wanted an engine, but here in the UK they are very thin on the ground, the last couple of years prices of used Sportsters seemed to have gone through the roof even for those in poor condition, this one came up close to home and the price wasn't extortionate, so he bought it.
