Exhibition weekend was last week and it went great!
We had a blast!

Here are few pics from the event










Nice to see lots of people looking and talking about my own project...


As you may have already guessed, I didn't won in any class  :D
Bike is way too unfinished, so we will have to wait until next year...

You also might note that rear cowl is looking like s**t.
I made it in one day from woodboards  :o  I thought that it will look pathetic if I don't make some kind of rear cowl.


Base is almost finished


Lots of grinding and some more grinding


This is the final shape and after that, I used filler, then some more grinding and finally put paint on it.

This will not be even close to what I'm looking for to do.



Also had a major backfire. From this picture you can see my problem


I don't have enough room for two middle pods, because rear shock has its capsule/container in the way...

Well I just bought new shock(s) and thinking of doing something uncommon... Stay tuned...




Today my friend is welding my sidestand shorter, because bike is way more lower than original, sidestand cannot be used right now.
He will also weld offset front sprocket.


Chain will be 530.
Old sprocket will go to turning machine (lathe) and it will remove all teeths from the sprocket. Also centerledges on both side will be shaved off.
New sprocket will have its one side centerledge to go.


After previous step, they will be joined together.


In two weeks I will receive my seat from upholstery. Can't wait to see it.
Next week my bike will go to mastermechanic, who will make custom exhaust for my bike. So it will stay in there about 2 weeks.


There might be a little silence in here for two weeks, but I will get back to as soon as possible  8)

I have question and I hope you guys could help me.
This might be very stupid, because I haven't done my homework/googling enough. Didn't find answer quickly...

What kind of options there is to upgrade DOHC engines eletronic ignition?
And does these thing have already electronic ignition?

Not sure about the K bikes, but the Fs have electronic ignition. It can definitely be upgraded if a lot of engine work has been done to make sure it runs as good as possible. Dyna is available but Ignitech is supposed to be even better. For the Fs one of the best and easiest upgrades is replace the coils with CBR F2 coils, which are just plug and play. Not sure if that applies to the Ks as well.

I have been looking for Dyna-kits, but everyone I have found is suitable only for SOHC engines.
I haven't put effort enough for the search and still like to here suggestions from you guys  ;)

Coils are already upgraded!

Thanks!  :)

Here's a DOHC kit on DCC (this one's with coils, didn't look if there was one without)

Bike is currently in a workshop for a custom exhaustsystem. Work will be done in mid-March.
Workshop will also fabricate plug for stopping oil spreading all over the engine from tachometercable hole (idk what it is called  ;D)

Before we took it there, we finished shorting the sidestand.


 

Shortened sidestand. Bike is way more lower than original, so it had to be done.


Welded little pin to the frame, which will stop sidestand hitting the frame. Have to buy a little rubberpiece end of it, so it will not scratch the paint




It came perfect


Friend of mine finished welding the offset front sprocket.


Looks amazing and works perfectly


Have to do minor work for the chainline. It is almost straight, but not enough yet


My seat came from the upholstery.


I'm digging it  :-*

Looks great! Donít think Iíve seen a custom welded front sprocket before, but thatís some really neat welding. I believe there are offset sprockets available from somewhere in Germany, not that you need it now.

If you know the company who makes these offset sprockets in Germany, please let know, because you never know when you need on of those  :)

That's some serious welding - I didn't know you could effectively weld hardened steel like a countershaft sprocket.  Looks like two sprockets became one?  Turned down another to use the splined section?

Too bad the weld will be invisible once installed - that's some pretty welding.
"Quality . . . you know what it is, yet you don't know what it is. But that's self-contradictory. But some things are better than others, that is, they have more quality. But when you try to say what the quality is, apart from the things that have it, it all goes poof! There's nothing to talk about. But if you can't say what Quality is, how do you know what it is, or how do you know that it even exists? If no one knows what it is, then for all practical purposes it doesn't exist at all. But for all practical purposes it really does exist."
