Yep. Just wanted to show that you'll be able to blend the kawi motor with the older parts and it will come out cool in the end if they can take a modern scout lump and makd it look like that.  Cheers

MT - yep, all down to careful use of styling cues and disguise ! The colourways will play a big part too. I'm pretty well settled on a light coffee with yellowish tinged cream [ Buttermilk ]

The stash is slowly growing !  ;) By the end of next week I should have all the major parts in stock - and quite a few of the small items.

The Weber KZ motor will definitely be the one for this project - I'll make it look the part !

Meanwhile I'm arranging to collect the late KZ motor from a pal at the end of the month for the Glemseck bike - also probably a complete spare bottom end.

POC time .......... yes - the Bantam forks will work with the XLR front wheel. The wheel spindle slot just needs opening up a tad to take the Honda spindle [ which just needs shortening ] and tyre clearance is OK.

I think the fork legs need to be a couple of inches shorter [ cosmetics ] - AND I wanted to get that Motobecane "banana" fork look. Again, what worked in my head looks like a goer. Unfortunately I ran out of sufficient garden hose [  ::)!! ] to mock up the complete banana shape - but at least you can see where I'm going with it ..... bit of imagineering required. Who needs cad-cam ! ;)

I'm going to use a couple of seat springs [ see pix ] at the top to give the illusion of suspension, and to a degree they will add some additional springing. ALL parts are available to refurb the Bantam forks - and not expensive.

Scratch the Motobecane styling cue fork legs. :'(

Yes I can get them to work with the basic Bantam forks - but that leaves no clearance for the bars to turn without the springs hitting the tank ! In the old days we'd put a couple of nice indents to accommodate that [ eg. Manx clip on depressions ]. NOT on my 110 year old NOS tank - oh no. !  8)

Oh well onto the next thought - H-D style hairpin springer ..... except they are fargin fugly. Well, we can make it less agricultural looking, just leaves the attachment and supplementary suspension / dampening. Yes - BSA neglected to put any hydraulic dampening in the Bantam forks ::) - well there was a bit of rubber tube [ !!?? ].

Cunning plan # 6 or is it 7 ? Use a RAMSHOX unit and use the 6262 alloy body as the means of fixing ! That eliminates any possible bending / pivoting of the hairpin as it moves up and down [ parallel ] with the Bantam fork leg. AND gives me 4 1/2" of travel with finite adjustment of spring platform and dampening. Effectively that renders the bantam forks as cosmetic. And the shock is mainly hidden so it won't look too out of place. A chrome spring and maybe a Black anodised body might add to the deception.

Needed to get a few things clear in my head - so a little shade tree "cad-cam" to the rescue. ;) 60" w/base and the forks will be a little more raked - still debating with myself what angle to use.

And final thought for the day - I got a quote for the Bantam fork stanchions to be refurbed [ hard chromed ] 175 - 200 for the pair :o  !!!! And that's only the 10" or so of actual contact area. Fuck that. So solution - some thick wall stainless tube machined to suit the bushes and with the original spring locators welded in. Material cost 30, labour - 30 ?


Major health assessment coming up next week - everybody cross yer fingers.

Yes - Chinabay again .............. I'm going to run a trans brake off the final drive sprocket [ hopefully ] to supplement the Honda XLR250 drums [ self preservation ]. Mini brake and caliper kit from Chinabay 7.00 delivered ...... YES THAT WAS 7.00

The special RAMSHOX unit arrived today  ;D..... based on a BMW Oilhead  front unit.

The plan I have is valid, but I need a shock with a 2" longer [ thread ] body and a 35mm instead of 55mm bottom extension. That's a stock base unit so essentially off the shelf for next time I go down there. That gives me 4 1/2" of travel and as much adjustment as I need.

Once the shock unit was in hand - immediately alternative methods became obvious. ::)

So the obvious is to mount the shock the other way up using the bottom yoke platform as the rigid attachment to the H-D style springer hoop and a simple bracket at the top end. That way the springer / shock becomes a rigid unit and can only move in a vertical and parallel motion.

We will need a shorter top mounting extension  [ which is a stock item ] and relevant length spring and we're GTG.

Then I thought - why not use a rigid pin for the top mount ? That way the shock is locked and can only move vertically.

New shock variant ordered 4.00pm yesterday - arrived 8.30 this morning ! Good to have mates. It arrived with additional collar and the correct length spring. Rates yet to be determined, but at least this will serve for the setup.

Reminds me of a push rod front end I once saw on a GT competition VW Corrado (might have been a Shiracco). They had to retain the McPherson strut arrangement to comply with the rules, but the strut was comprised of a large tube and a slider, meanwhile the dampers and springs were inboard. Your design is basically the motorcycle equivalent. Neat! You could even do a rocker at the top and a push rod from the lower and get rising rate.

Thanx for the input ..... yes well pleased with the outcome. I just have to get the parts made now . That means CALLING IN FAVOURS - or paying top dollar.

I had contemplated rising rate as you suggest - but to be honest a Boardtracker is never going to win any races around the twisty bits ! It's really the overall "look" I'm going for. I would have given a testicle or two for the Motobecane banana forks - but not to be. I'm fortunate inasmuch as I'm totally familiar with the RAMSHOX [ my baby ] and will have an adequate [ more than ] of adjustability. Another stroke of good fortune - the Honda XLR250 wheel spindle is only a gnat's bigger than the  fixing in the Bantam fork bottom. Literally a quick wipe with a round file and job done. Oh, except the spindle has to be shortened by about 3" and re-threaded. Even the brake anchor aligns with the Bantam mount !
