Harris Magnum 4 W

[Spike]

I think the wheels suite the line of the tank and seat unit.
Curved lines.
I also have a set PVM's 6S, but rather put these in my upcoming 1100ET.

 

[Spike]

Does anyone perhaps have some pics, drawings or measurements of engine mounts for a Slingshot engine? 

[Swirl]

Cracking looking bike that, looking forward to what you do with it.

So many projects, so little time...

Decided to swop the W-engine for a proper oil-lump.
So the bike went on the bench for a hart transplant.
It'll have a tuned engine with 1201 Wiseco's, ported head and some RS38's or FCR39's.

Further more swapping the swingarm.
Standard one is gorgeous, but always loved the Benelli TnT ones in the frames.
Problem is, I hate excenters!
So cut them off and replaced them with some slots.
Still have to "clean" them up and make some nice adjusters.
But the carbon Dymag looks great!

Are the W mounts the same as for oil cooled engines?

[Spike]

Needed the 750W front for an other bike.
So time to put the WP front in.
It has a carbon Dymag wheel ,8-pistons Spieglers and PT pumps.

[Spike]

Still had the double headlights on, but thinking on putting on one of a KTM.
Have a small Over fairing lying around, so might going to try that one swell.
I'm a great fan of the little Martek style seat units, so swap the Harris one.
That'll go on the Harris Magnum 2 in the near future. Same as the Mag4 swingarm.

[Spike]

Thinking of powder coat the frame red and keep the rest in carbon...

The frame is the same.
Mounting points are a few mm off.
Wasn't that hard to make the 1127 lump fit

Enjoying the build on this. Magnum 4 is my favourite Harris. Going to watch this and see how it builds up

[Dezza]

Can't go wrong with a Harris frame . Personally, I prefer the original Harris swingarm over the Benelli item. Their welding and fabrication skills are second to noone but it's your bike and the whole point is getting it the way you want it.

I think the tnt arm suits the frame really well bud, I like the seat unit and the red frame aswell .

Quess to many projects the reason it took so long you took the water boiler out 

 

Looking good man

Hi @SpikeI do like that seat unit. I know you say its a Martek unit but where are they available from ?

Bought it a while back at Fighterama in Germany. I believe you can still find them on eB*y. Made copies of it, so have a few… 

[clivegto]

This one looks nice as well bud. 

[Wagola]

Seat or swing arm ? Or both ?

Great find , I know of another magnum 4 that had a gsxr w engine . It was sold recently the guy worked at harris and his was the only one made with Reynolds 531 tubing as he had kept it for his bike .

 

Lovley find . Be good to see you put your own stamp on this build 

[BasilBrush]

Always liked the old magnum 4. Used to have the mags when Specials of Glasgow (?) and PB mag built the first one. Showed all the mock ups of the tubing etc. Lovely bike . Looking forward to seeing your build. ready for Summer ?

[Swirl]

Very nice, love a Mag 4 

[baldrick]
