Looking through my pile of old brass from the CB550 and CB500 carbs i used to rebuild the Scruffy Racer, i see that i have two types or air bleed screws the original set from the CB550 carbs are solid brass, the ones from the CB500 have drillings the carb rebuild kits contained air bleed...

The title says it all really, is electronic ignition worth fitting to my cb550? are there actual running / performance gains over well maintained points? if so what units are best for the sohc 4s? should i also replace coils? 5ohm or 3 ohm? TIA ! steve

Hi guys building up a 1980 dohc cb750 motor with +1mm ie 63mm pistons and have twisted a piston ring it still goes in the piston groove ok but is a bit tight for my liking so ideally need a replacement it is the middle ring that i need, or a single piston set. i believe this is the 425 type...

Hello sage ones! Scruffy, my cb550 project bike, is getting a set of big bore pistons as part of Phase 3 ‘make it go!’ i’ve read that the cb650 sohc camshaft offers a performance increase, probably at high revs? is this true and if so what’s involved with the change? does the cam fit straight...

Covid Lockdown gave me the time for my Scruffy Racer project, but also helped me crystalise my thoughts on work : I dont want to work any more ! so my work here is done. i’ve signed up for a voluntary redundancy package and my last day is 30/9 meantime i’ve ridden my GS850 down to Denia to...

I need a replacement tank for my 1976 CB550 project, the one i have is more collander than tank ! as i’m going for a ‘scruffy racer’ look i’d be happy with a solid but tatty looking tank, am happy to clean and seal it etc. Most of these will be in the USA, i’m happy to pay postage but as i’m...

Following the success of my CB390 project and likely to be bored self-isolating for a while I’ve bought a fresh in from the US CB550 project i’ll document here how i’ve sympathetically restored it to running order with some subtle upgrades to brakes, electrics etc. for today here’s how it...

Hi folks! After a couple of years enjoying my CB390 i sold it last summer to part fund a Ducati Superlight itch. the Superlight is indeed fabulous, but i was missing the little Honda..... so next Tuesday a project CB550/4 is being delivered ! not fully sure what the plan is yet..... Steve...

Hi folks, seeking some carb setting advice. My cb360/390 is running beautifully, starts well, idles well, pulls to 10k in every gear :-) I can get a solid idle at around 1200 revs too. However when the bike is fully HOT after a good blast and i stop at a junction, then the engine hesitates...

Morning all, following the resounding success of the 390 rebuild on my cb390 i’m moving on to the wiring ! I dont like there being spare wires, dont like the big bunch of bullet connectors at the headstock, really dislike the bodges put in place by the po! So the plan is to strip out the...

Hi electronic gurus ...... Ive fitted a simple digital tacho to my cb390 today Three wires for ignition, earth and sensor. Connected the sensor to points output, ie the blue or yellow wire to the coil. I’m getting very high and unstable rev readings, which i’m guessing is due to noise ? I...

Hi everyone, i’m back after a period away from messing with my 360. Have an oil weep from the head to barrels join, both sides, so am going to strip the top end down and potentially bore and install gs850 pistons. Looking on ebay there are new aftermarket pistons available, or old engines...

Out for a spin and find the petcock is leaking, makes a change from the engine leaking i suppose! Bike hasnt been used much in 15 years, but now back on the road so i guess its no surprise. I've fitted new and genuine honda 'four hole rubber' gasket thingy and new spring washer, still leaks...

So..... Am really liking the idea of upgrading the front end of my cb360 to twin disks. I want period 1970's disks not modern stuff or usd forks etc. Im thinking of using a '74 cb450 lower triple as i believe this has the same stem length as the 360? ( probably a billet upper and taper...

My cb360 is running great, but there's a slight oil leak from the clutch pushrod seal. I replaced this when the engine was out, so am surprised/disappointed. On inspecting i see that the pushrod is bent! Theres clear daylight when its rolled on a flat surface, guess this is the problem as the...

Following the axle spacer and stuck float valve incidents the little Honda 360 Cafe is running great. However I'm experiencing a slight 'twitch' when turning into a slow corner/junction. Bike is fine at speeds over about 40mpy but at 15-20 mph there is an instant of instability upon initial...

Hi guys I think my cb360 is getting a little fuel in its oil The bike was off the road for a decade, and the po bought some used ' refurbished carbs from somewhere..... I cleaned them out and the bike runs well, but I think the oil level has gone up a little and the oil smells slightly of...
