Supermono build on the go

So the build has begun.

I thought I would start a post on my exploits whilst building a Husaberg 650 engine Supermono. Any advice / hints / tips from anyone would be much appreciated.

First off here’s the background. I raced in the nation endurance series for a couple of years with a bit of sponsorship from the RAF here in the UK. It was good fun but going round a circuit for 45min sort of “playing it safeâ€

Cheers Taff, Had a good old study of the galleries as well as anything else i could find on the net.
The biggest thing on my mind at the moment is how to go about mounting the front of the engine. Its a fair distance to bridge.

Well things ain't gone that well now. With having the house flood from the shower and the insurance company sending in Muppet's to repair it all (the Muppet's have since been told to put there tools away and leave my house before they mess anything else up) work on the bike has been slow.
The past week or so when i have had time has mainly been spent measuring/lining up/measuring/removing/measuring/re-fitting/measuring etc etc
Final plans for the front engine mount have been drawn up and wheel spacer's and engine spacer's are on there way.

Taffy i read this as you needed help with a rev counter; Obviously i miss under stood.
A tacho is low on the list of things to do with the project.

On another note at some point in the new year I'll be wanting to get the engine checked over by a pro. If you are up for it would you need it running in the frame or out. And the big one, how far are you from Nwales?


PS Many thanks to Dr_C, Looking at his Gallery gave me the best option for mounting. (hope you don't mind me using your idea as a basis)

i'm 4 hours from home at betws so i guess you're another hour. i'm at soham in cambridgeshire just north of the A14 at newmarket. you'd go A5, M54, M6, A14, A142 to soham. i don't mind looking at it but that's a bit of a misnoma isn't it?

don't attempt to RACE the bike without a rev counter.

Hello Dave and thanks for your email!
Good to see the creativity blossoms in North Wales!
The upper end of my front engine mounts incorporate the bushings from a Peugoet 205. This reduces the vibrations on the frame. As aluminium is quite sensitive to fatigue cracking, rubber bushings was chosen. The downside is that the exhaust system will get all the vibrations instead, which calls for a very flexible design of piping and mounts. I have sorted it out by now, but that was a lesson learned. The upper mounts were CNC-machined and welded against the frame.

I saw your sketch of the front engine mount. I would recommend you to avoid the "T-joint" between the horisontal tube and the both vertical tubes. This design is very susceptical to fatigue cracking. From the pictures it looks like you have excellent possibilities to use the existing upper mounting holes on the frame. You can bolt an alu-plate directly against the frame and use a rubber bushing between the alu-plate and the tubes going down to the front engine mounts. I have seen this solution on more than one Supermono. If you use rubber bushings too close to the engine you will increase "leverage" from the engine moving around, which will increase the forces to the rubbers, or even let the rear mount take all the stress. It's better to keep the rubbers further away from the engine to reduce the force on them. I'm not good at explaining this so I depend on you being equally creative when interpriting my english!

You asked about the tank. I used the stock RS250 alu gas tank, but cut it out and fabricated a new inner "shell". Little tricky with the air ducts coming straight through. The welding was done by a local TIG-wizard, but I have gained the possibility and training with the TIG myself nowadays. If you prefer to work with glassfibre, you can fabricate a dummy, and use a more square shaped fuel tank underneith.

Good luck and let me know if i can be of further assistance!
