CB750 cafe racer build

[jonbuoy]

Cheers,

I have thought about a big bore kit, problem is from what I understand I'd be needing a decent port job as the standard heads are pretty restrictive, then carbs to make the most of the port job and then a higher lift cam which would need stronger springs oversize valves, and then I'd be needing rods, big end bearings & primary chain, to handle the extra power. I know a few guys on the SOHC forum have been getting close to 90BHP from these engines, I just can't justify the cost which would probably be close to $10K for an extra 15-20BHP. Would be cool to give the odd 600 rider a fright, till the first corner when I'd be the one getting the fright

My choice AND MINE ALONE, its a "Cafe" racer, not a "Road" racer, if it looks good...it must be. DONT bankrupt yourself, or take ten years building a FUN good looking bike. Get it on the road and ENJOY. See ya out there

Hey thats looking sweet, did you make the mold of the seat yourself?

[xwhatsit]

Yeah I want to know about the seat Having trouble tracking down a cheap seat/cowling.

That looks great.

[Duc]

I got the seat from Malcom at EconoHonda. He took a mould off it before he delivered it to me so maybe he has them available now.

BTW -I have another seat cowling for sale - cheap. Might suit you X....

Nice work guys!
Getting the urge to do anothery. What do you reckon about an XS750 triple? For me it's not about performance, it's all about looks. And sound!

[jonbuoy]

750 triple sounds like a great idea. Got the motor up and running and its now a fully rolling chassis, Cycletreads sorted out the chain which was good quality and almost new but bizarrely too short when I bought the bike. Needle bearings in the swingarm , wheels and oil tank painted, braided oil lines. Number plate is the original but was black on white. I stripped it back polished the aluminum and masked and sprayed the rest. Might go for a smaller one later, it looks vintage so I'm happy at the mo.

Exhaust took a while to fit - chrome is pretty shabby but it will do for this riding season anyway.

Motor up and running on Sunday - spent half a day trying to prime the oil pump using starter motor pouring oil in various places. In the end I fired it up with the cam cover caps off and kept spraying oil the old fashioned way into the cam and rockers till I could see oil squirting out. Fired up first time and runs nicely considering I only bench synched the carbs and set the timing by eye.

Brakes Rearset linkages, gas tank sealer, exhaust and final tank adjustment, wiring up the idiot lights is pretty much all thats left to do. Then its off to the warrant station and on the road

[Goblin]

That looks Stunning!! Have really enjoyed watching the progress. Well done!
Cant wait to hear it. Bet it sounds sweeeet!

[deanohit]

Dude, that is looking awesome!!!
Good work.

Hey there.. was stoked to find this wee thread. Am in the strip down stage of a CB650C chop down to a bobber style rebuild. Would like to see how far you've come with the build.
I do have a question re the machining you got done.... what did you end up handing over and how much did the work cost..

Did you do a complete strip down of the bottom end or clean it up with transmission intact?

[xwhatsit]

What a mint idea, inverting the plate colours I've half a mind to do the same with mine once I get the tail sorted, looks very classic. I know you can order new plates for very cheap ($20 or so, `it fell off'), but can you specify which shape you want? My existing one is long and thin, not so good.
