CB750 / Re: Compression Advice Please
« on: April 05, 2017, 03:26:16 PM »
Dave, You're getting double the compression of my bike and mine will not start as a result. I would test it again after putting a few miles on it.

Sorry Hairy Git. lol.
All of the cylinders are between 65 and 85psi. with the choke off and the throttle open.
The bike has run on all four briefly a couple of weeks ago, then only three then maybe one, then two, its all over the place.
Last night i tried starting it and only one cylinder was running, so i thought thats it!!! I cant keep blaming the carbs or the timing so its a complete strip down and rebuild.
I have already bought a gasket set and new valve stem seals, some lapping paste etc.
Plus with the engine out It will allow me to restore the rest of the bike.

Just need to see the size of the pistons to get new rings etc. 
Oh well, just adds some time to the restoration.

Thanks Graham,
Ive done most of that.
I cant do the redex thing as it wont start, or it only runs on one cylinder. it flattens two batterys trying to start it sometimes and still wont start.
Judging by the rest of the seals in the oil pump and all around the rest of the bike it would benefit from valve stem seals etc so I think I'm just going to go for it.
If i'm honest, I am sort of looking forward to getting into it.
Thanks for the advice though buddy.

Been struggling to start my 750 K5, refurbed the carbs, changed leads, plugs, points, timing is spot on, etc etc. Thought I would check the compression. only 65 PSI per cylinder.
I suppose thats what you get for buying a bike that hasnt turned a wheel since the 80's. (USA Import)
So engine out, valve relap, stem seals, piston rings and honing I suppose.

I've had the same issue with my indicators on the K5 USA.
I just replaced the relay with one like this and no more beeping.

Thatb truly is a beautiful bike, you should be proud.
My experience of the American ideal bike would be to take something as beautiful as that and put a gordy king and queen seat and ape hanger bars on it. so probably best not to ask Chris. LOL.

Thanks all, I will get in touch with them in the morning.

Hi All,
I havent long moved up to the midlands so do not have a network of suppliers/mates to help out with my "projects" yet.
I need to get my wheels vapour blased and rebuilt.
Does anyone know of anyone in the Solihull area that can supply and fit spokes and rims and vapour blast my hubs please?
I would take this on myself but would like it done properly on this bike.
Ive spoken to Central Wheel Components and they wanted £500.00 to do the pair. i'm sure I didnt pay this when I lived down south.
Thanks in advance. :D
