Ducati ST4s custom build

Thought I would start a new build thread on my ST4s custom now the Multistrada build is finished.


So here it is as it arrived. It’s a running bike with 22k on the clock. it’s not as tidy as it looks in the pictures, the paintwork in particular lets it down. It’s a runner, but it had some electrical issues, which were easy to trace, the loom was a mess!

progress on this build will be a little slow as we have summer soon, and a few extended holidays so garage time will be limited. I will be doing some jobs though!

I have now stripped off all the parts that I definitely know I won’t use, and these are being sold to fund some of the build. First little job has been to machine the top yoke and rough some clamps out so I can fit conventional handlebars, to make it easier for me to move it around, and so I can sell the originals.

I am not sure yet on the style this will end up, but it needs to be reasonably easy to ride, no clip ons! I am also going to make a tank in alloy this time, and work is already underway designing and making an English wheel which I am quite excited about.

I took the Multi out yesterday for its first short ride and was REALLY pleased with the way it run on the new ignition and carbs... and that got me thinking... I don't think anyone has done a 996 engine on carbs...(most will say why the hell would you!!) I like the idea! So I have sourced a pair of nice flat slide 48 mm carburettors! Watch this space!

I have decided to give the keihin 48mm CV flatslides a go... these are off a Honda VTR, and apparently they are some of the biggest carbs fitted to a bike... unless you know different of course! they have come up really well...

a little bit of progress, I have made the first manifold out of plate and tube, its came out quite well... I have managed to mount the carb at the same angle it was on the Honda VFR it came off.
