Any plans to remove the airbox and mass airflow sensor?

Hi Racket sorry for my late reply.

I'm quite busy with the bike actually, first of all i'm riding it at them moment. There are major traffic jams each morning during the fact that a bridge is closed for trucks. There a some cracks found :(

This weekend I will go to Millerkustomupholsty for my seat design, leather color, stitching and so on.

At this moment i'm riding with strap-ons, however this is not very comfy at all so i'm attending to buy a super bike handlebar and mount this up-side-down on the existing handlebar holders. Still thinking of it.

Regarding the air box and flow sensor. I'm working on a solution to get rid of them and use a custom made air box (I will use a stainless steel tube) and create a mount to attach a K&N filter directly on to it. (a few people done this before) Will send some picture when I have it all cleared up. If u like it then I can help you make one yourself.

This winter the complete bike we be teard down and repaint all parts.
I'm going for a grey frame, black on black on black rims, tank, fork.
Brown seat and grips.

I made a small mount for the KOSO speedo i'm using and now I'm awaiting the BEP 3.0 to make it work  :riding:
Picture will follow.

Also I have a huge question on the footpegs. Does any one has some advise which rear sets to order or anything els.
I saw a few on a china webshop but not sure if they will fit. I'm willing to make a plate my own and add steps and brake/gear peg to it but I don't know where to start and get all together.

Cheers,
Nick

Nick,

BSK Speedworks out of the UK has a rear set specific for K-Bikes.

http://www.bskspeedworks.co.uk/k-rearsets.html

Pricey, but no mounting plates needed.

Hi guys,


I'v been out for a short because had a full agenda at work and private.
Looking back on all your response and the information gained in the time.


What happend in the last weeks?!:

Bike teardown
Cutting the frame and making the frame straght
Painting the engine
Painting the rims
Painting all the "small" parts
Painting the tank
The seat is finished by Miller Custom Upholstry from (NL)
Getting a new batt from MOTOBATT
Speedo received the KOSO DB03 + extended all wires to arrange it to the BEP
BEP 3.0 received to make the speedo work propperly
New rear spring is ordered and will arrive soon

Now i'm finishing up the frame and get it painted.

I'm make a custom airbox to fit the flow meter and ofcourse end up with a nice K&N air filter  :riding:


Any questions are most welcome !

Hi guys,

Yeah there has been some changes during the months.
First I had a problem with the rearshock, now I have the YSS shock.

Then I had a leaking oil/waterpump now fixed.

In the meantime BEP 3.0 installed with the koso speedo, got the RPM working but the speed not yet. So have to dig into that again.

Made a airhousing to place an K&N airfilter :)
Ps: making some extra to sell :yes

But then, my crazy mind decided to cut the frame again and make it a single seat instead of 2 person seat.

The crankshaft is from an SWD F240 engine (we deal/supply new and reconditioned Wartsila and SWD spare parts)

Nick,


Can you provide more details on this? Did you have to remove the stock airbox entirely? I've seen this done many times on the K100, but not on the K75.

It's fun to see your project progress as you take apart your bike and put it back together, transforming it into your vision in the process.  Having done just a little bit of work on my bike to make it roadworthy, I can appreciate all the effort, and expense, you have put into this project.

Hi all,

This quick reply window tells me that there is no post done for at least 180 day.
Again a lot has changed to make this project a real custom project.

The complete frame is chopped, the rearshock is now horizontal and the full subframe/tail has been modified.

The DGR is comming up 30th of September and I’m keen te get the bike 90% done by then.
Except for the new painting job which will be done by a painter.

Hope to get some more pictures online this sunday.

Cheers
Nick

This is a slippery slope. I speak from experience. I too chopped my frame again and kept going and at every point i thought maybe I should do more so I did and I ended up with something with no finished project in sight kinda. Bike is looking good so far though.

Hi Roland,

I’m already working on the rear shock and it works now.
Below is a short picture of it. Any tips or recommendations are welcome. Can still adjust all :)

I have a question. How did you weld stuff to the final drive? its cast so I assume the weld was very dirty, if not I would like to know what it was like? was it an easy weld and does it hold up to the stresses of the suspension? thanks. Make sure to really adjust the dampening on the shock. You can put a shock that kinda works and it will be fine but if you wanna go fast I would take the shock to a guy who knows what they are doing(unless that is you) and revalve it to go with the now progressive shock movement due to the nature of rockers. thanks for the pick. it looks real good.

No No welding to the cardan or any engine parts.
Made a bracket that can be mounted and bolted on the rear stud on the cardan (original shock mounting point) and the 2 upper bolts of the cardan on the swingarm. On the frame I welded a nice "cage" of thick metal plates which holds the upper part of the shock in place with a M12 bolt trough the needle bearing on the shock eye.

Hope this is sufficient :)

Thursday I wil get the frame back from the welder, then its cleaning time. Make all edges of the frame smooth and also the weldings. Guess I can manage to get the frame also painted. Ill drop some picture once I have them.

To day the rubber manchet of the clutch system ripped apart and all the oil is now on the floor hahaha.
Ordered a new manchet, so there is more work to do then I could image. I'm also waiting the fork seals to start rebuilding the forks and paint them also. I have 5 weeks left to finish the bike (not the tank painting, this will be done later) because I'm joining the DGR again.

Hope I will catch some eyes, because its the same bike, different looks hihi

Are you planning on using the Ohlins shock? If not are you willing to part with it?

Thanks,

Got the frame back from the welder, smoothen the weldings and sandbladted the rear part of the frame.
Saturday will be painting day for the frame, engine, custom airhousing, seat, rims and fork.

Any updates on small adjustments such as removing the relay box, relocate the relays etc will come later on.

Picture of the frame.
