    Have you considered beefing up your swingarm?

    Hi Indianaslim

    Not really thought on these lines but like the picture is this something you have any experience of ? I guess its depend how much power is being put down.....

    Getting into a stride now... ok a brisk walk

    Finished off the battery holder used the ali solder again really like this stuff.

    Then after the cock up on the valve hole couldnt wait for the replacement tube to turn up ( so impatiant) so stuck the tyre on the wheel just to take a look - the drag tyre with soft sidewalls was so much easier then the front to get on. So as this was only a tempoary fit its not 100% conclusive however the clearances to the swing arm look good and there is ample room to restore a gusset arrangment to the spindle area.

    Next up we had bought a universal set of rearsets quality was good and they have the ability to move the actuation point about which look as if it might be handy, the plan was to use the origonal rear peg locations to bolt these up but its never that simple. The fixing bolt which fiited within the peg was not even close to being a good fit so we made up a spacer

    New tube has arrived so this was fitted this morning and then we were on 2 wheels, tyre to swing arm tube now we have some air in there is a bit close for comfort so looks like the grinder is coming back out for some action.

    The forks have been fitted but without the new bearings so very much jury rigged for this trial, forks went through various iterations as we experimented with ride height. At this stage all we wanted to acheive was the desired ride height so the faring could be mocked up and then look at making mounting brackets so dont take too much notice of the forks at this stage as the day progressed we have come up with what we hope will be the final solution just need to sort out the springs.









    So that fairing.... we started by pulling it passed the barrels and then spent ages getting the right stance bits of wood and boxes....ready to mark up the section which would be cut round the barrels we would keep these as small as possible at this stage and look to do teh final fitting when all the mounts are in place





    Next up the front mount was made up using some already tapped holes in the headstock.



    Cut outs for the barrels



    And sort of mounted to the bike

    Also remember that rear tire will "grow" when it gets hot. Look at a video of a drag car and you can size the tire increase in diameter.

    Under power the rear of a BMW "jacks up", which may give that rear tire more clearance.

    Dexter, my experience is all '73-'77 BMWs. In the search for better handling the things I've done were:
    billet top clamp and fork brace to firm up the forks
    frame braces to reduce flex
    swingarm brace to reduce twist.

    In your case maybe the swingarm brace is the one that may have the most value.
    Thank you for posting all of this, I'm digging it!

    Thanks for your thoughts, the swingarm brace may well be an option as this has to have gussets and final welding done so may be an ideal time, will see what tube i can line up for bracing duties and se how we go

    Hope to have the tyre growing covered with additional clearance being on the list when the swingarm comes out next - looks like that swingarm is really going to have a number put on it...............

    Thanks for the input

    Almost too nice to cover with a fairing

    Hi Buknekk4d

    Not really sure its going to be linked to the gearing which is a guess at the moment and then sourcing a bevel box which is closest time will tell

    Got a load more work done over the weekend

    More fairing stuff, so not the best photo but these are the 2 tubes to secure the top of the rear fairing section better photos to follow - fixing bolts will be bespoke, the design has been drawn up just got to make them..... The concept is to design fixings so they can stay in place on the fairing when its removed and use R clips to locate these fixings to the mounts on the bike ( i know what i mean but hopefully some further photos will help)

    [IMG][/IMG]

    Next up was making the mounting for the lower section of the fairing, the mounting point ends up about 150mm back from the wheel center line and will suport the main weight of the fairing. These are constructed from thin wall 18mm box tube with tubes welded into the place and using the motor bolts as the fixing points so good and strong - althought the fairing is pretty light.

    [IMG][/IMG]

    And then welded up

    Thanks for the kind words and here is today's progress.

    More faring action.......

    First up were the lower mounts using 2mm alloy folded to shape round the trusty argo bottle.

    [IMG][/IMG]

    Once the holes had been drilled with a piolt drill these were opend up to take the m6 threaded inserts.

    [IMG][/IMG]






    For final assembly the screws can be cut down to lenght and we will use a thin rubber gasket type material between the brakets an the fiberglass

    Next up the stays that support the top of the rear section needed some mounting bobbins.

    [IMG][/IMG]

    [IMG][/IMG]

    These were joined together with the ali solder...these will get a final finish to blend radius.

    [IMG][/IMG]



    Final assembley will be with the same gasket material.

    Got some time and progressed the front fairing stay into the instrument holder....

    So we started off like this

    [IMG][/IMG]

    And then this happened

    [IMG][/IMG]

    [IMG][/IMG]

    [IMG][/IMG]

    [IMG][/IMG]

    And finally riders eye view with the idea that both should have the needles pointing to the top when in anger.

    [IMG][/IMG]



    Frame will have some lightening holes added, been on the phone to RM who is sourcing the -3 hose from the pressure gauge to the engine and the plug leads as part of the origonal engine build now we have confirmed the length.

    You like ? they were Ebay specials from China good price and the quality was excellent, we liked the multi adjustment so hopefully when this thing goes down the track we can find the best position for comfort... and speed.

    Cluster looks unbalanced - needs a boost gauge on the left side.

    Man you have a turbo fixation but seriously thanks for the feedback........maybe one day if I really get the bug bad.

    Take your mind off turbo's and have a look at this weeks work

    Made up the rear brake bar, it will use a rose joint at the lever end, should have some pics making up a fitted bolt.......



    Silencer, we were going to make one but having been down this road before and seen how much work goes into making it from scratch this came a long at a very good price it even fits with the measurments RM has specified, some bends have been bought this week to add to some pipework left over from a previous project so its exhaust weekend coming up.....



    Next week we take a pile of stainless pipework and try to turn it into some headers...
