Topic: What did you do to your bike today ?

[chewbacca5000]

I rode ole Blue around Onedia Lake and stopped at bike night at Sylvan Beach and he was the only old Honda in a sea of identical looking Harley's and one old 4 cylinder indian.  I parked next to a 65 Triumph that was leaking oil and gas everywhere!

It was fun having hearing all the old timer who rode in on their Harley's say I used to have one of those years ago and rode all over.  It really made me appreciate how lucky I am to own such a cool bike.

Modern bikes just don't do it for me.

Been busy in the garage getting this finished:



Should be on the track in October, which means I can make space for my next Honda CB project, another F'ing F.

WOW...nice!   What is it??

It is a CB450, built in the style of the Bob Hansen racing CB450's of the late 60's.

@retrorocket - I was going to clothe it but it just looks so darn good naked, so this is how it stays.

I may yet put it on the road...

[Jerry Rxman Griffin aka MuthaF'er]

That's nice! Great job.

Very impressive!  Tell us a little more. Stock motor?  What's that bottle on the side??

[maduncle]

Okay Stev-o, short version on my CB450 build.

The CB450 motor was stripped down, cleaned, barrels bored out and re-sleeved, then the new sleeves were bored out to take 74mm pistons., making it 497cc. Head was ported and polished and fitted with race valves and megacycle race cams. Capellini oil pump fitted and external oil lines delivering oil into the cams. CR33 carbs fitted. Starter motor removed and blanked off.

The frame was modified with the centre brace removed and extra bracing put in to match the Hansen bikes of the 60's. Suzuki GT750 4LS brake drum into an 18" rim on the front, CB450 rear drum modified from rod actuated to cable actuated brake.

Honda CR450 replica tank made in India because UK suppliers would not answer my emails. Davis motorsport seat and rear sets. I made the brackets for the Davis motorsport fibreglass front fender.

The silver bottle is the oil catch can, with both cam cover breather tubes plumbed into it, required on the track.

Progressive springs and emulators in the CB500T front forks, YSS rear shocks (locally made and good quality).

I used an aluminium tank, left the kick start spindle in and made up a side stand that bolts on and off, so that I can convert this bike to road use later on if I want by adding headlamp, brake/tail light, speedo and handlebar switches. If I do this it will be made up as a 'plug and play' system that can come on and off the bike as required.

Now it is finished I am ready to do another Honda SOHC4, I have sourced a CB750F1 and hope to do a careful resto-mod as has been shown successfully here by Tweakin and others in the past.

Now you see why the 450 is the most impressive Honda ever made Stev-o !!!!!!!!!!!!!!  Seriously though, the 450 is one of the best vintage foundations for the cafe racer format.


Excellent work maduncle...Larry

I know someone who would sh!t himself if he saw this gorgeous bike  Maduncle, that is an absolutely stunning little ride! Sounds top notch and looks equal to the performance side of things. This would definitely be in my garage!

[Jerry Rxman Griffin aka MuthaF'er]

Decided to get the front end in the air. Mock up continues in lieu of the rear end. Gets slow when you have to find and clean every nut, bolt, part etc. Looks like a 77/78 F swing arm is needed to solve that problem. Will need to have the shock mount lengthened though.



I'm getting real happy with this but won't be able to wrench again until Tuesday. I'll preview the colors Tue or Wed.

[n9viw]

No pics, sorry. Drained the gas tank, cleaned the filter, removed the carbs and cleaned the jets, then reassembled everything and took it for a spin. For the full tale of woe, I just posted it under "Help me SOHC4 Kenobi... " etc. Sunny days driving a 4-ton diesel pickup SUCK.

I like the blue with the gold wheels Jerry, that'll be a looker when its all done {and you didn't have to marry it !!} ...

Love that tank graphic too - might be "borrowing" that for my future F build.

More pipes to the people!
4-4 fits very well. (Thanks Yamiya!). After a year they finally find the place on bike.
 I know now that OEM rear foot pegs are a must for correct assembly. The cheap aftermarket is too thin and too small hole. 12mm, 14mm needed. The foot peg mount must be several mm thick and shaped that fits the exhaust. Ordered a complete set from Yamiya together with new OEM mirrors.

I hope a friend that has plenty of CB750 parts have a set of pegs over so I can run it this weekend.

"Rat stopper" removed from bike when it cannot be healthy for the flow to block the pipes almost completely. Ok for stopping rats but not the power! Look like beer bottles 

[Jerry Rxman Griffin aka MuthaF'er]

Stock tank Uncle.

Went buzzing around town running errands on her. It's funny how much attention that these old girls get.

They do look like beer bottles PeWe!!! I never heard anyone call them rat stoppers but I guess that's a good description. I think the bike sounds much better without them as well.

Actually started assembling my motor.

I hope it will sound OK and not too much. The "rat stopper" for the motor vehicle inspection every 2:nd year when the bike is a veteran. Without the fiber mat. I'll spray the inside with black rattle can heat resistant paint.

Whats the inside coated with?

Or is that just a reflection?

[calj737]

Glyptal. It's an oil shed coating. Prevents any pooling of the oil and helps promote lubrocity.

[PeWe]

Got the 4-4 on with correct rear foot pegs. Important to get the pipe on the spigots on head completely before mounting the rear bolt. Not possible to force pipe on spigot afterwards when it will become locked due to the spigot angle.
Risk to damage the pipe too. Especially number 1 made some additional work. It must be wiggled on without any rear bolt in.

I started the bike without the diffusers (baffle). Not too loud on idle anda little revving outside my garage. Rain stopped a test ride. Hopefully tomorrow. The carbs need to be adjusted again when the idle is more D-D-D-D-D again. Before RRRRRRRRR spinning like a smooth machine.
Hopefully fuel screws only. Closer to OEM look. I have ordered new OEM mirrors from Yamiya. Today Z1-900 mirrors (cheap copies not as good as my old real ones)

[joeyvans]

Great looking  bike, PeWe! What brand/specs steering damper are you using? And, do you like it?

[PeWe]

The steering damper is an old one from the early 80's. It looked old back then when new too
It make a huge difference. I do not want drive without one.

I have always the hardest setting. Helped a lot during touring with 2 people (slimmer and younger) and luggage that made the center of gravity to move backwards, easier to get front wobbleuphill or when twisti ng the throttle.

It must be this model that Yamiya has except for the frame clamp. I use a cheap exhaust clamp. I might order a new with better clamp when my damper is leaking a little (old and dry seal).

I guess the quality is not that good. It must be crap, but who knows???

[mcpuffett]

Filled my KO tank with gas ready for my next ride  cheers Mick.
