The new project......

Post by sharky » Sat Dec 10, 2011 6:54 pm

Decided to go way back to the days when streetfighters were just beginning to appear...

Image

Big aircooled japs...rigid frames...tuff as f#*k......No fancy paint or pretty bling....just down to earth 'fighters..

I'll be using a stock XJR frame and grafting in the swing arm from an XVS650 Dragstar
Using this instead of the harley arm as its designed to pivot in the conventional place( compared to softails pivotting a lot further back)

Image

The cast ends will be replaced with steel plate and have the axle slots/chain adjusters etc added and a new front spindle tube welded on.
Using a mix of parts I'll mock up a front end to match the length of my R1 USD's and will use a 17" R1 rear wheel to get a roller.
When the time comes, and this is gonna be quite a way off...like a year or 2 at least, it will be stripped down, powder coated and my current motor,f/end etc fitted to it.

This should minimise 'off the road' time for me.
Plan is to end up with something like this....

This is just a rough mock up to see if it works in theory...next stage is permit to mod frame/arm etc...easy job, just paperwork.
Currently its siting 130mm over stock...will probably drop to about 100mm over.
With the arm at stock bike length its too stubby..

So...first step...to fit this arm into the XJR frame...

Image

Front tube needs to come off and be replaced with one that matches the stock XJR frame.
Once this is done the exact pivot position can be determined...either stock mount or moved back..depends on overall look...The lines are important as it has to mimick a hardtail.

Then the axle plates are coming out and some nice new 8 or 10mm water cut ones made...

To do all this properley a good mate has been busy with some wicked material for the jig...and making a damn good job of it too..

Ok....so after going to my old club site (to leave RIP's to 2 good mates) I found this as the Galleries main pic...
Image
This got me thinkin.....and after a long chat with the vehicle mod bloke in Qld ( good bloke...knows his bikes) I found that to do a twin shock to mono conversion plus subframe was almost as much paper work, inspections etc as doing the custom ICV.....

So a quick mock up...
Image
Seeing as I already have the 'Permit to build' I just have to apply for the changes to the design...ie new swingarm/monoshock and subframe.

First thing was to get the correct position for the swing arm pivot...so using the spare stock frame a simple jig was made connecting 2 engine mount points and the pivot...
Image
This is then just transferred over to the custom...easy.
Having a finished road bike of same allowed me to then measure ground to engine mount points and use these to set up the frame.
End result is the frame sits 30mm lower than my current ride but as that has 150mm of ground clearance I have room to play.
Image
This now sits at 1570mm wheelbase, stock is 1520mm...so not much over.
Next up is an adjustable rod to allow s/arm travel...and thus get a seat height....

Next up is making the dummy shock...max and min length to set up travel, seat height etc.....Got a bit carried away...
Image
Thought I might as well 'copy' the shocks as I will be mounting them 'Vincent' style. Spoke to Gazi shocks..no probs with angle..obviously spring rates will need to be sorted but thats the easy bit.

Seat height is approx 600mm...Looooooow

Good to see some humour.

Dad had a Rapide. the fact that it could comfortably do 100mph was quite a thing in the 60's. I got to ride it a bit but she had a tricky two stage clutch and was very high and heavy for a short young bloke... plenty of poke though and handling was better than most thought. Blokes on their fancy Jap bikes used to look down on her, but once again the old boys have the last laugh. Same rear suspension now on a lot of bikes and BMW even did a girdraulic front set up. My cousin now has it. I would love to take it for a ride and compare with my shovel.

YOur bike is loking good, but gee... needs a bit more rake I reckon.

Yeah...not sure about more rake...currently its within a gnat's of stock...I'll see what the final wheelbase ends up as...don't want to create something that won't corner..
I know a drag frame builder that could do the rake...mates jig isnt set up for headstock work.....we'll see....
Going to offer up my late model stock XJR tank....don't really want to use harley/jap cruiser style one......may do a custom tank or a fuel cell with cover....
