It's been a while since my last post here...

Yesterday i received the last parts needed to get the bike running again. Some fresh pictures to start off:

I have to admit i actually like the look of a stock seat, side covers and duo shocks better these days. Maybe an idea for the next project...

I would rather have the shocks on the outside and easy to adjust, and to change.
also the swing arm is supported better. Equal on both sides.

Just my opinion.

looks good for what it is! def. detracts from the "classic" look, but it's well executed! i'd say that it will be a fun ride!!

nice looking bike

I recently bought a new frontend for my cbr900rr. You can guess where the old one ended up... It was a quite easy fit.

The footpegs moved. I like an aggressive riding position but it was to much. They were to far back to keep the weight of the bars. I definitely wanted to keep the kickstarter functional so the pegs ended up in a nearly stock position. This also gives me more room to mount passenger footpegs.

I also bought a stock airbox and it looks like it will still fit (the carbs are mounted incorrectly). This is very nice because i don't like pods. Been there, done that, got the t-shirt...

As i posted earlier on, i am changing the direction of this build a bit. I really like the look of the House Rockers Cb750's.

Next on my to-do list: track down a fender, taillight and some sidecovers. I'm sticking with the monoshock (for now at least).

That thing looks sick!

sander · « **Reply #131 on:** September 30, 2012, 06:12:12 AM »

Thanks!

I found a fender of an old kawa kz750 and it fits this bike perfectly. It is even wide enough for the 180 rear tire. Mounting the fender was a bit of a hassle because i had removed the back part of the frame for the cafe seat.

I also got a cb500 taillight which i think is the same as a cb750's but smaller? It's nice and small anyway.

My brother, who is a graphics designer, is making me a new faceplate for the tach. Can't wait to see what he comes up with!
Does anyone know if you can place the needle back on the shaft in any position or is it fixed? I want the redline on 12 o'clock...

754 · « **Reply #132 on:** September 30, 2012, 08:45:42 AM »

All Honda used that taillights from 68-71. Just rotate the tach to get redline up top.

sander · « **Reply #133 on:** September 30, 2012, 11:00:05 AM »

Did they get bigger after that period?

I just took the tach apart and now i'm sure my plan is going to work. I can just press the needle back on to the shaft at another angle and match the new faceplate.

754 · « **Reply #134 on:** September 30, 2012, 06:28:18 PM »

bigger till 77/78 then maybe shrunk a bit..

time to paint or powdercoat that swingarm!

Hi all! I'm Sander from the Netherlands, new to this forums.

As my wheels were all wobbly, i thought i might as well put some modern wheels on my bike. Well you can guess the rest, plans got bigger and bigger...

So i bought myself this:
-cbr900 rearend (incl. monoshock)
-cbr900 wheels and brakes
-cbr1000 frontend (same inner bearing sizes, only a little longer

Sander

What year of cbr stuff did you use

sander · « **Reply #137 on:** October 03, 2012, 08:24:11 AM »

It's all from the 92-95 model (sc28).

dangerdan408 · « **Reply #138 on:** October 04, 2012, 09:18:26 PM »

Awesome buildup, really wish I could do something like this.

sander · « **Reply #139 on:** April 20, 2013, 12:39:05 AM »

Hi, it has been a while since i posted... I have just a tiny update on the tach.

Nice and simple, with the redline on top. I like it a lot!

sander · « **Reply #140 on:** April 28, 2013, 07:22:11 AM »

I didn't like the look the of the stock seat/fender with the monoshock. So i decided to go back to the cafe style...

I finally soldered new ends to the throttle cables to work with the cb carbs. Changed the front master cylinder to one with an integrated reservoir (of a cbr600f). I also sorted out the wiring of the new reg/rect of which i lost the wiring diagram.

Things left to do: replace some cracked fuel lines, set the Dyna S timing, final check wiring, fit airfilter, charge battery and see if it will fire up...
After that: make bracket for tach and oil pressure light, fit brake lines with correct length, and make a seat pad.

This bike has a great stance. Hope it handles as well.

sander · « **Reply #142 on:** July 19, 2013, 10:08:27 AM »

It runs!! I'm still waiting on a new chain and then i can road test it...

sander · « **Reply #143 on:** July 20, 2013, 03:38:44 AM »

dusterdude · « **Reply #144 on:** July 20, 2013, 04:55:05 AM »

Damn!!,i like that

sander · « **Reply #145 on:** August 04, 2013, 08:24:05 AM »

The new chain is fitted, this means i can go and ride this bike. I still have a few issues though...

The oil pressure switch is stuck in the open position, so it will need to be replaced.
I also came to the conclusion that the bottom part of the airbox won't fit because of the monoshock construction. I am yet to decide whether to cut only the rear part of the airbox or to cut it down completely so it will only seal up the filter. I will order new rubber stacks as the old ones have shrunk to 36mm inner diameter! I think i will order repro sidecovers too, i like the look of them and used ones are hard to find here.

sander · « **Reply #146 on:** August 05, 2013, 02:40:48 PM »

Great news! The airbox does fit, after repositioning the external shock reservoir. Luckily i didn't cut the bottom part of the box yet...

sander · « **Reply #147 on:** August 07, 2013, 01:17:17 AM »

The carbs are 086a's, the engine is a k5 and the airbox seems to be a 76 f model. So i'm guessing 105 main jets would do the trick, with the needle on 4th clip from the top and 40 pilot jets?
I have 130 jets in the carbs at the moment, as a result of messing with individual filters, and lost the original ones. I never got it to run great.

sander · « **Reply #148 on:** August 22, 2013, 10:24:39 AM »

New rubber stacks really do make a difference!

The carbs are set as stock and the oil pressure switch was replaced. Then, I finally got to ride the bike again after 5 years... It starts first kick, runs great and pulls strong from low rpm's without missing a beat.
I was also pleasantly surprised by the handling. The bike is very nimble but without feeling nervous at all. I will try to make a video of me riding the bike soon.

The almost finished product (it still needs padding on the seat and side covers would be nice):

Looks great! Looking forward to seeing how the bike performs - video would be great.

Keep the updates coming!
cheers
Andy
