Looks like I will keep tothe later style.

Hi,
Does anyone know whether the oil tank from the K series bikes can be fitted to the F1? I can see that the oil lines come out of the tank differently, but not sure if that procludes putting on the earlier tank.
Thanks

Hi all,
I've just purchased a cb750k2 USA import, the CB was my dream bike ever since I made an airfix kit of one when I was a kid.
I also run a 1962 BSA super rocket and to compliment that a 1964 Vespa GS160 so it's nice to ride a " modern " bike at last.
Can anyone recommend someone in the Essex/east London area who services these machines so he can give it the once over for me
Thanks in advance
Hi, I can recommend https://sanddmotorcyclesltd.co.uk/Its near Brentwood. They look after my CB750. The owner learned on Honda's and has a love of them. Good luck!

Hi John, no need for a fuel additive, Honda designed the engine/seats to run on any fuel the bike was likely to encounter back in the 60's, luckily that means that they are able to cope with the ethanol laced rubbish that we are sold in the U.K. now.
Although I'm answering a question that was not asked.. whenever I know that the bike is not going to move for a while I add a fuel stabiliser to stop the hydroscopic ethanol separating from the petrol.

Thank you!
In that case I will save my tokens for other things. I'm really enjoying the bike at the moment. A switch to more modern rubber that is at least round rather than square in cross section (!) has really improved the handling. I'll put up some pictures after I next take it out.

Hello,
My '75 F0 has recently been treated to a weisco 836cc kit and is running much better now (its still running in). Its much more lively! I'm not sure how much of the benefit is coming from the extra capacity, how much from the extra compression and how much from the fact that pressure is not just leaking past the pistons - it smoked a lot!
I know that the later F2 head has larger valves than the one on my bike. I see from the dynoman site that they have developed a weisco kit for the F2 head that makes use of the extra space and means that you won't lose compression.
My question is, given the development I've already done would an F2 head be a bad idea?
Thanks

RE BHP I used a big bore kit on my my DOHC 750, taking out to 823cc + cams + flowed head and carb mods. Gave 95 BHP at rear wheel after proper dyno set up at TTS. Big percentage gain over 78 BHP ish (at crank) for stock I think?
Keeping in mind you are talking SOHC / 8v, therefore poorer breathing and less output to start with, something less than the 95? Not very scientific I know....
It did transform my bike both in terms torque and top end but yes to get all the bits working together it is a big expense to consider....
Thanks. My engine was not performing very well to start with, if an 836cc bore with standard head and cams can get me anything above the stated standard output then it will feel a huge improvement.

Well the more I've looked into it the more it seems costs would get out of control for little gain.
I'm having the heads inspected and since I've already had new valve seals if the valve guides are okay I will probably just fit the existing head with the 836cc pistons. Once I added up gas flowing the head, potentially fitting new valve guides, a new cam, stronger valve springs, it starts to add up to silly numbers!

Thanks, point taken.
I didn't say what I was after. I'm not after performance at the top end, a bit more go at the bottom end would be welcome, but I'm fitting the pistons because I'm currently burning oil and have pretty poor performance, so thought I might as well go the whole hog. I'm going to have a word with Kent cams to see whether they can suggest a re-work of the existing cam.

Hi,
I would be interested on member's thoughts on my SOHC rebuild. I'm having a set of Wiseco 836cc pistons fitted along with a copper gasket. The head is also being flowed, although the valves will remain standard size and I am sticking with the original carbs. Since I'm having the engine apart to this extent would it be a good idea to go to a different cam, along with stringer valve springs etc, or could I just have the existing cam re-profiled or left alone? Some of what I'm reading suggests a cam is necessary to get much benefit from the slight displacement increase, but there are plenty of builds where the standard item is retained.
Many thanks

Truly inspiring stuff here!
I love the tank especially. Can I ask where you had this made?

I'm in the process of having a 836cc kit fitted to my F1. I'm going for the Boyer system.

According to the mechanic who has worked on my CB750 its the bike I should have bought!
