Thanks mate, I’ll get in contact

Frame is back from the welders, stoked with how it’s turned out. 

Fitted the rear wheel and took some measurements, fitment clears the frame even with the big tyre.

Added in a bracket to mount the seat latch mechanism too, also doubles as frame strength.

Continued on with the engine build today, got the piston and rings in, everything was going great until we noticed small cracks on the camshaft where the timing chain cog fits on. Turned out to be cracked right through on both sides. Yip that’s game over for that cam.

Had a play with the headlight. Managed to order the wrong size so it’s huge haha but was keen to see how it looked with a yellow tint.

Once the smaller one arrives I think we’ll keep the yellow as it pops against the blue.

Next is the wiring, so much to do before the Distinguished Gentlemen's ride in Sept!!

Edit: man that rear tyre looks huge, thinking of down sizing as it looks a big out of proportion in the profile shot.

Carried on setting the motor up today. Kept the points instead of a CDI as there is something oldschool mechanical that I like about them.

Tensioned the timing chain at 90 degrees after tdc. Then set up the points timing and tested the coils, got good spark so she’s getting very close to starting now!

Fitted the headers and noticed there isn’t much room between them and the rearsets. Might have to make some out of 35mm ID pipe to get the clearances.

Finally kicked this thing into life this arvo. Started easy as and sat there idleing like a champ.

Stoked the motor is working as it should have. One step closer to the DGR ride!

Still have so much to go, mainly wiring as the indicators don’t blink, starter motor is dead, rear set linkages etc.....

Indicators not flashing will just be the bulbs/l.e.d not drawing enough current from the relay. Swap it out with another one. 

Its a nice build man, tidy!

I think i have a new fav os bike build!!!!!!!

Supercheap and AE both sell solid state flasher relays which work with LED indicators. They are good even without led lamps because they make the slow flashing at idle problem lots better.

I do think your headlight is too high and vote flipping those brackets :-D (I'm also not a good judge of style. )

Thanks guys! It’s been a lot of work to get it to this stage.

I’ve added an LED flasher unit so I think it’s something to do with the wiring not being quite right. I’ll revisit the wiring once the controls arrive from AE and try to knock it out all in one go. 

Super Trapp reps should also be arriving too this week as there is an issue with the exhaust and rearset brake hitting. Probably going to make new headers to get the clearances.

Anyways she’s come a long way since the Trademe purchase that’s for sure!

Big update mostly about clearances.

Firstly the Supertrapp reps turned up and wow are they mint! Did a test fit and fired it up which sounded great, stoked!!!

Now clearances, looking at a lot of other CB350 builds I always wondered why they added aftermarket headers. With the rearsets I realise that the factory exhaust sits too high so the brake leaver hits the muffler. Also the kick start hits the rearsets too, bit of a cluster really.

Gave it a quick tune with the glass plugs, found the 70 idle jet ran too rich so swapped it out for a 68 which helped when tuning with the Air/Fuel mixture screw.

Also added in the blue titanium hose clamps round the carbs, kind dig it kinda don’t, they are quite wide so they don’t quite fit. Can see them in this pic.

The push button controls turned up for the handle bars too; again quality and feel is immaculate so far, they also did a perfect job of setting up the buttons as some were momentary and others were push on/off.

Test fitted them to check and happy with the fit/clearance. I’ll thread the wiring properly down through the handle bars eventually.

Realistically this bike won’t be ready for the DGR ride on Sunday so the CB250k is hitting the ride again this year with the DGR headlight stickers to support men’s mental health.

Lastly found the winged Honda badges I brought ages ago to stick on the CB350. Factory colour is to fill them in white but I reckon black could be the go. 

Thanks for looking!

Carried on shaping and sticking on the badges, originally for the early CBs with the square shape tank but I liked them so much I picked up a replica metal set and stuck them on. 

Was going to paint the badges but like the raw alloy look so gave them a coat of Matt clear to keep them crisp.

Drilled holes in the clip ons and feed the wires through for the controls, now on to the major wiring to make sure everything works like it should.

Fitted up the gear linkage I got from AliExpress, so mint! A tad short which was completely my fault as a don’t know how I got the measurement wrong but hey it works!

Next is to build an exhaust which doesn’t hit the rearsets!!
