CB750 scrambler project
-
Here's a totally random and probably going to take a long time project.
I bought a chassis with v5 very cheap.
yzfR6 front end
Longer cognimoto steering stem. + Top yoke
Continental tkc80 tyres.
Custom tank.
Seat will probably be changed again.
Currently restoring the carbs.
Frame is at the Powder coater after cutting and welding for the seat hoop and tank mounts.I'll get the rolling chassis built up, then custom fenders, battery box, install brakes, controls, lights etc.
If I see a really good bargain on the parts I have just bought them and started cleaning (carbs, look, CDI, )
Going for satin black with some shiny features, modified exhaust and custom intake airbox.
Probably Bitten off more than I can chew so I'll be doing it whenever I get a chance.

woow, looking great.
your bottom forks what you used? powder coating?
-
Yes yes yes yes yes!
Looks like an awesome project!
-
@Calum thanks, it's a bit of a crazy one. Time consuming too.
Still need the engine but looking for a decent at a good price -
@pedrobatista10 which part?
The front forks aren in good condition.
Swingarm is powder coated -
@Louis-DT-WR i mean where the calippers mount on the fork. that black is original? it looks great thats why i asked. i may need to do the same on my rs250 forks.

@Louis-DT-WR A twin disc set-up sweettttttt!!!!
-
@NINJA yes indeed, it's the R6 front wheel
-
@Louis-DT-WR Are you building this for off-road on on-road use, or a bit of both?
-
@NINJA road and gravel tracks but mostly for the fun of building it.
The bikes too heavy for off-road and the suspension is too hard and not enough travel.It's a bit of a madmax/walking dead type of bike
-
Together they look like this.
Brat style
-
Frame is now powdered
New tapered headset bearings installed.
Front end half on
New top bushes for the rear shocks to make it compatible.
Here's a little mock up.Just waiting for my new bike lift to come.
I've got some pod filters on order + crank case vent filters.
Rejetted carbs using an online calculator (I will fine tune but as a starting point for the intake and exhaust mods)I have a slightly nicer/longer seat now which will suit my stealth appearance.
It's very hard to visualize in your head but I think it's looking more or less like how I hoped

After a bit of haggling I got an engine from a 12k mile bike (running) with warranty. I believe that is genuine, I will remove sump and cam cover to inspect+ comp test. And flush the lubrication system.
However the seller advertised it as a CB 750 nighthawk 1992 to 2003. It looks identical apart from what I couldn't see in the pictures.... It has No clutch arm!. Meaning it needs a hydraulic slave cylinder.
Also the electrics are not compatible with my loom, the cbx750 engine has loads more wires for shift lights, selector drum position etc.
I've now got to get the pulse generator sorted, source the main generator+ cover, starter motor+ cover.
The CBX has larger valves, maybe just exhaust?
Both engines have pros and cons.Right enough spending for a bit
luckily selling some old DT parts has really helped.
A bit of elbow grease and this engine really came up .... I haven't even painted it
Thinking about mounting the lights to this and using the slots for height adjustment.

@Louis-DT-WR loving the build so far. I fell in love with honda back in the late 90's after owning an nc30 for a couple of years. I must say for a "probably going to take a long time" project, (your words) lol. You have sure progressed quickly enough. At this rate you'll be riding it within the next week or two.
