CB750 / Wheels mis-aligned!
« on: June 12, 2016, 04:07:23 PM »
Hi all, took the K7 for MOT yesterday and it sailed through except we couldn't get the wheels aligned (got soaked to the skin in to the bargain >:()  Tester was using two straight lengths of ally. We had to adjust the rear wheel miles out on the chain adjusters.  Hopefully you can see from the photos that the chain side is adjusted out about 5mm more than the brake side. As far as the tester was concerned it wasn't a failure as long as the wheels were aligned so the bike passed.

When I rebuilt the bike the right, front brake lever side, fork leg was found to have a small bend in it.  My question is, if the bottom yoke is twisted due to the same impact would it kick the front end out that much?

Cheers, Jamie

CB750 / PD carbs oddity!
« on: June 10, 2016, 10:05:09 AM »
On my K7 the non adjustable slide for balancing purposes is on number three cylinder.  My understanding is that you count the cylinder numbers from right to left sitting on the bike.  Am I correct?  The manual states that the idle screw is between numbers 1&2.

If someone has split the carb bank and reassembled in the wrong order I guess it doesnt make any difference but wondered if anyone had any differing opinion.  It does seem to be a bugger to balance the carbs, even with tappet and timing settings bang on; getting a lot of clutch rattle.

Thanks all.

No, that's with everything connected.  The more I think about it the meter must be at fault. Ill borrow another meter to double check.

CB750 / Battery reads 15.4V
« on: June 09, 2016, 07:52:01 AM »
Hi all, thought i'd check my battery voltage yesterday and got the above reading.  Battery is a year old and visually looks good, Dave Silver 'MF' from memory, spent the winter being plugged into an optimate for 24 hours once a week and insulated against the cold.  I instantly though dodgy meter, so I checked my beemer battery which has been maintained the same way (its an odyssey) and it gave a similar reading.  Went and checked my van battery and it read 13.4 volts. 

Anyone had similar experiences?  Could the optimate be on the way out and both batteries are toast?  :'(

I guess electronic ignition units are only as good as the loom/charging system.  Cant see the problem with using the existing advance and retard unit as long as it is in good condition, particularly the springs.  I fitted a DS unit and haven't had any issues; I felt it was re-assuring to eliminate timing issues when setting the bike up.

Before completely giving up on the can, give S.E.P. in Kegworth a call. I gave seen them repair cranks that look like ploughed fields by submerged argon arc welding the journals, then grinding back to original spec, and the crank is then good for many years to come. Chances are the journals on your cam may respond to the same treatment, and may prove easier and cheaper than trying to source a replacement.

+1 sending to SEP, they will provide the shells too.

CB750 / Re: Indicators not flashing
« on: May 22, 2016, 04:55:53 PM »
Are you using the original indicator switch?  I had exactly the same problem, tried all sorts and it turned out to be that the switch arm was travelling too far across the contact bar because the mechanism was worn.  I restricted the travel by spacing out the housing and the indicators have been perfect ever since.  I might add that the switch didnt feel particularly loose or wobbly.  Might be worth a try, but fiddly taking the switch apart...... ;)

CB750 / K7 Tacho needle sticking.
« on: April 03, 2016, 08:18:20 PM »
Hi all, my tacho needle is sticking.  It will go up normally to about 4 thou and then it jams.  A good couple of slaps on the top of the case will make the needle return.

Any advice on how to fix or is it time for a second hand replacement?

Cheers!

How very sad..I bought a set of forks off Ralph a couple of weeks ago and we shared some laughs, be it over the internet via email etc.

I can only send my condolences to his family and hope that the knowledge that he was a real gentleman to me can be of some comfort.

R.I.P Ralph

So after a couple of hundred miles post rebuild I noticed an oil leak which I put down to a pattern head gasket, but seems like the head has 'settled' onto the barrels and consequently the head bolts are now loose  :'( - like finger tight.  Now I know all you lot will be scoffing and querying my torque wrench or mechanical prowess, but I can assure you everything was torqued as to honda spec with a snap on wrench.

Is this a common issue or does anyone think that the nuts or threads could be worn?

Anyway...off to the garage tonight to get the lump out.
