A quick update on the XL1250, its paintwork was collected from the painter this week, should be on the dyno in the next couple of days.. I like how the hole in the side panel for the ignition barrel have been incorporated into the Hammer and Tongs design .. a v old symbol used by the Army Royal Engineers.

Rubbish pic, but the XL1250 was finished (for now) just in time for a local bike show. Goes on the Dyno soon, be interesting to see what it makes.

Here's a better photo of the XL1250 taken by the River Mersey today. Its been run on the dyno using ''guestimate'' jetting where it made only 65 bhp. Once the jetting is corrected it should make more, but still not as much as it could, as its still running the original 883 cams and CV carb. Then again the aim is lots of low end torque rather than top end power..

Can't you set it up to 1200 Buell 'Lightning' spec?
That makes  as much 106 bhp when set up right (friend had one, I liked it  ;) )
Modified 883 heads  work great as the smaller port can be shaped to work right on a 1200 (better than stock 1200 head) but, if you can't DIY them, after-market works out cheaper

The heads have been flowed and a bigger inlet (I think) fitted. I'm sure its the standard cams that are holding it back. My mate owns the local bike shop, complete with dyno. They usually work on Jap and Italian superbikes, but I'm sure they can get plenty of power out of this if they wanted.

My home made alloy swing arm, which has become a mini project in itself, got welded today. It all went ok with no distortion etc. Still to decide if its getting the under bracing of the original steel version its copied from, and what finish it having. Polished, powder coated or maybe anodised?

Its half the weight of the original (17 Vs 34 lbs), still heavy for a sports bike swing arm, but pretty light for a Harley Softail..
