MrFry's CB750 Build Thread - AKA I need a hair helmet to wear on my pink bike

[MrFryMoto]

Hmmm, time to finish my end of this.

eh, you got time. I still need to get the oil tank, then comes the complete tear-down.

I wouldn't put the rectifier in the box with the battery, it gets hot

[Popeye the Sailor]

I would put the battery and the electronics in the hump

not sure the battery would fit - it's pretty tight back there
...plus i don't have the hump here for measuring

So what's the old Honda in the background. CT90/110 or what? Hard to tell. I can see the red covers over the shocks, unlike the exposed springs on the later 110s.

I may happen to be building one up here in Australia, see .

Thought so... Frame design is the same as the later 90s and 110s. We still use 'em in Australia as motorbikes for the postal service. Rebuild details in link in my sig, but that one at least looks like a runner, as opposed to my ebay-jigsaw-puzzle special I have. 3 years after getting all the bits, at least mine starts and is close to being rideable...

hah
i wish it were a runner
this is one my father had sitting in his shed for 25 years... full of fuel.
You don' know varnish until your chipping it out like rock

i rebuilt the thing probably 4-5 times now, but everytime i get it running the damn thing seizes.
i'm currently looking at selling it or finding another engine
problem is every engine i find that has the trail-gears and honda-matic transmission is something like $900

i'll probably end up posting another thread when i decided to do the rebuild (again) on that guy

Hrrm. I actually have at least 2 other good CT110 motors I need to rebuild . They're 4 speed centrifugal clutch, no hi/lo. Freight's not gonna be cheap to the states though. A fair proportion of the annoying parts to get came from the states though - mainly cause they're so freaking expensive here due to their cult status at the venerable postie bike.

I'd know varnish... I just rebuilt the carb for the one I have running. I coulda probably cleaned it out, but I just soaked the carb enough to get all the bits out and replaced them all with a carb kit.

The cb750 is a great base for a cafe project.  Here's one that a friend of mine did about six years ago.  Sorry about the small pic.

good looking bike!
i keep toying with the idea of a full fairing - but i think i'll keep it naked

looks like he's done some pretty interesting mods to that

I agree...

the pink on the fairings would be a bit much.

*shifty eyes*

fabbed up some brackets to mount the rectifier, and the fuse block last night (under the tail).
still trying to finalize the oil-tank design - it's pretty small (1.75 qts), so i think i'm going to need an oil cooler as well
