Honda-SOHC

I have had a bike from him in the past, the guy's a gentleman, he is not a dealer but a collector.
Can't get to see bike online at present due to sporadic Internet connection, but I found that he will answer any query, he used to do walk round videos as well.

Like most bikes make sure you ask the right  questions.

They are different inside - the removable end caps/baffles are a lot different. The HM300's have a longer removable baffle where as the 341's have more of an end cap. As the 300's are noisier, I assume they are less restrictive and so in theory, would affect the running on 1 & 2 compaired to 3 & 4 I would imagine?

Thank you for your help.

I thought I would take a look inside so I took the end caps/baffles off to see the difference and, lo and behold!, all four are the same, short ones, possibly the long ones were changed over.

I was looking at exhaust sets on internet, pricey, but may need to be an option if I don't think the bike is ok with these exhausts. I also noticed, reading various comments on the forum, that quality and fitment vary greatly, with people mentioning DS, and CSML, I also found Predator do a set but couldn't find much info on them. Possibly trying to source two nearside ones would also be an option, but that leads to ensuring they are good and solid.

We will see how it goes, if I need to get others I suppose I will need to bite the bullet.

I am looking for a bit of advice please.

I am doing a bit of cleaning and fettling on a recently acquired Cb750K5, I turned it on without starting it the other day and noticed the oil light didn't come on, previously it had came on with the ignition switch.

I checked the bulb, ok, then disconnected the wire from the switch, and checked for continuity from the wire switch end to the bulb holder, again ok. I removed the switch gave it a good clean out and wired it with a test light and using a air compressor gave it a few blasts, every time the air went in the light went out which indicated to me that the switch was working; anyway I put it all back together again and it now seems to be working, quite possibly just some crud in the switch or maybe the connection was not too good previously.
However, just in case it isn't going to last I would like to buy a new one to have as a spare, I got the part number, 37240-P13-013, and looked it up, over £50 which took the wind out of my sails a bit, especially after I bought one for my now sold Guzzi 1000S for £10.

On the CMSNL site, when you click on the part it gives you a list of vehicles that that part number and part would fit, and, along with a large  number of Honda bikes it also fits Honda Accords. I know some car pressure switches can actuate at lower pressures but I was wondering, if the part number was the same surely the actuating pressures would be the same?
 Typing in the part number for Oil Pressure Switches for  Accords brings up a number of items for about £10, which is a lot better than £50 if I wasn't going to need it and it was just going to lie in a drawer.

Any views on getting the part for an Accord, as I mentioned the Honda part numbers are the same, so surely the operating pressure would be too?

Thanks

Hi there, motors are definitely capable of mega miles as long they are maintained well.  Regular oil changes are a must! In reality you'd be lucky to buy a 37 year old bike without having to do something to it - I actually bought my 750 to fettle as I enjoy the challenge and would rather be in the shed than watching the brain numbing drivel on TV :-)

In my honest opinion, if you want something to ride day in day out get something newer, but if you want something that will require regular attention and repay your input with bags of character get the CB!

Good luck!

Thanks, I also  enjoy working on my bikes, I have a 1965 BSA A65 Lightning Clubman which I totally rebuilt, and a 1992 Moto Guzzi 1000S, both which are keepers. I just wanted something a wee bit different from the twins I usually have and was thinking of the CB750, as I've never had a four before and they have a good reputation. It doesn't need to be a 'K' model as I also like the F1, I know a lot of people prefer the K with it's 4 pipes and original looks, but I'm lucky I like the look of both!
You are right in the respect that, for day to day running I could/should go out and get something  new or a few years old, that may yet happen, but since I retired I don't do half the mileages I used to and tend to use the bikes when the mood takes me so that was part of the reasoning for looking at the 750. It has a reputation of being reliable, good looking,(both Ks and the F1 in my humble opinion), good for spares, and they are not all that common on the roads.
Thanks for your opinion, that is why I asked , to get other's opinion to help me look out for a good one and what to look out for.
Cheers

Thanks to all,

Hi I am going to look at a 1970 CB750 K0, UK bike, quite close to me, I have only seen a picture so far and was not sure if it had the correct style of rear light and bracket for that model as I have seen some pics on the internet with 2 differing styles.
Are they both correct but for different markets?

The one on the bike in the advert has a black bracket ,similar to the one in the picture which has a support piece going towards the seat direction, basically shaped like an inverted "L", it has a rectangular rear lens with straight ends, is the bracket correct for year, should it be chrome, and is the lens correct?, I have also seen a pic with a lens that is rectangular but has rounded ends.


The other one I have seen is chrome with just a vertical arm, like pic below, this one seems to be more widely fitted.


Any help appreciated ,
Thanks

I may be wrong on this so invite others to comment.

I thought many of the original exhausts for this era were double skinned where they leave the head so making it slightly more difficult to repair effectively, mainlt to stop them going blue at the highest heat point.

Hi, No you are quite correct it IS double skinned and I realise I either go for a double skin repair, weld a piece in then another on top, or a single thick piece, I think it might be worth it as the pipes are in really good nick apart from that and the silencer is solid, also I like the look of the routing of the pipes.

Hi,  a quick hello as I have just joined the forum having bought a  Cb550 F2. It was registered in 1979 but I'd imagine it's a '77 bike. The bike was described as  in excellent condition by it's previous owner, however on closer inspection, our descriptions must differ greatly, quite a lot requiring doing!

It has come with a motad exhaust system on the bike but I did manage to get from him a full original system with the silencer totally solid although No.1 pipe has been hit by something and torn between the head joint end and about 3", there are no scratches/ road rash on the pipe so it's not been down the road, I'll look into getting a repair and rechrome.

I have a couple of  other bikes a Guzzi 1000s and a 1965 BSA Lightning Clubman.

Although having numerous bikes over the years I have never had a four cylinder engine, this may prove to be fun!!!, always thinking that a twin was enough to be contending with for working on, (although I did have a Thunderbird Sport), my vacumn gauges are just a pair so maybe need to get a four set.

So here's hoping the ownership will be enjoyable, now onto the CB550 forum with some questions.

Chere
