Topic: First serious build ever - CB750 K7 Café

Alright, progress. The triples are on their way to get powder coated, which motivates (forces) me to make a solution on widening the front. Going to make a new wheel axle. The spacers are extremely easy to make for CBR1000F as it uses two spacers stock (which are about 10mm and 22mm in width) so I'll just make two new ones and add 10mm to these.

It should be somewhat easy to make new brackets for the calipers as well, but that's a later headache. I want to get the thing rolling before I start working on the brakes.

[cb750tr]

Easy part done. Awaiting triple to get back from powder coat and I can assemble it.

[cb750tr]

So far, so good!

[cb750tr]

Updates in real time! Making some spacers for one of the calipers!

[cb750tr]

I'll take it!

[budman]

Nice!

[cb750tr]

Started on the other side. It's a lot more complicated since the caliper bracket includes another cylinder that engages one of the pistons in the rear, and I'm not going to use that, so I do not have anything to mount it to on the other side. So have to make a custom adapter bracket.

I started with changing the offset 10mm by milling that much off the lower mounting point and making a spacer, which seems to work fine.



That's as far as I got today, took a lot of thinking and setting up to be able to do it right.

looking good 

[cb750tr]

Almost there!













Everything's lined up and in place, the only thing I have to do is to mill a flat adapter bracket to mount the other side of the caliper bracket.

Stoked!

[cb750tr]

Boom. Front end complete.

[cb750tr]

Lost count of how many times I've done this.

Needle bearing for caliper mount?

It had three of them stock. I have no idea, never seen it before.

It's awesome to have a new workshop dedicated for just my projects, just a few minutes away from home. I can go and tinker for just an hour or so, when I want to have some time to myself instead of dedicating my entire afternoon like before.

I really love how the front end and top triple turned out. The bike has another stance, and I absolutely adore these rims on the CB750. So far the project is going to plan.



Got the last milling done of the brake adapter yesterday. So now the front end is completely done, just waiting for the cylinder to arrive from China (I'll take my chances with it).



Also got the carbs cleaned and assembled again. The rust from the tank had clogged quite a bit. Especially the fuel lines and the needle valves (or whatever they're called). Fortunately they weren't damaged, and are once again sealing properly.

I'll go with a bottle for a tank until my new tank arrives... From which I've stopped getting e-mails from the guy making it, so I'm starting to get a bit scared about that. I hope he hasn't decided he doesn't want to do tank and seat anymore. That would be a bummer...



Also removed the intake rubbers from the airbox. One of them is really, really stiff (think plastic). Going to give it a try with soaking in some oil and see if I can mend them, or if I have to try to find another set. Hopefully not.

A blend of Wintergreen oil and water, boil the intake boots in it, softens them right up.

Will try this, thanks Cal!

Is it Methyl salicylate you mean by Wintergreen oil, or is it a specific product called Wintergreen oil?

[calj737]

Here's the standard "process" used by many:

- "Put ~2oz of wintergreen oil into a pan with enough water to cover a set or two of carb boots (maybe 1/2-3/4 gallon depending on pot size).  Put a screen in the bottom so they don't touch the pan, and heat them to near boiling (when those little bubbles start forming on the boots) for about 30 minutes.  When they dry they're like new again.

Make sure ya do it outside unless you want your house smelling like a Wint-O-Green lifesaver for a month."

Yep, same stuff, Professor Chemistry

Awesome! Thanks very much. I'll return with the results, but I don't see why this wouldn't work!

I also ordered an M-unit now from your recommendation! Cheers

[calj737]

I am sure you will like it.  Now you just need to pony-up and get an M-Lock too 

I looked back and didn't see any mention of it, but while your forks were apart, did you service the oil, seals, and/or upgrade the springs?

I ordered their new unit, that comes with a Bluetooth connection to enable the ignition button as far as the motorcycle is in range. So, I won't bother with an M-Lock

Yeah, new oil, new seals, new bushings. Stock springs, as the CBR1000F has quite a bit stiffer ride stock. I'll evaluate (or rather, let someone who's a lot better at riding than me evaluate) and see how it is.

They've got a new M-unit soon launching, with Bluetooth built in. It comes with some new nifty functions, tracking distances, turning on / off the alarms and getting logs etc. But the best part for myself was using your smartphone instead of the key. Even if you've got an ignition lock, you can use the phone without needing the key (if I understood it correct).

Any details on this new version of the M-Unit from a website, email or other source.  Sounds interesting, but I haven't seen anything about it on the Interwebs.
