Misc / Open / Re: What do you own 2019? (Main bike only please)
« on: March 16, 2024, 01:17:49 AM »
I am greedy.  I have 11 of the things.  Different sorts, Single, twins, triples and 1 inline 4 and a rotary.  All collected over the last 45 years or so.  And 1 more recently.  All rebuilt, some a complete rebuild and some just a good recommission with new tyres etc.
I don't really have a favourite.  They are all different.  All that matters is that when a dry day arrives I can still pull one of the machines out and spend an afternoon riding about in the country or further.

One day it will all be one of those things you USED to do....

If the front wheels are the same diameter the drive box will be the same, is this Suzuki GT or Kawasaki GT
I was not brave enough to assume that.  But having just checked the part numbers for a 1974 gt750 and most years of a gt550 the drive box numbers are all the same.
Now, if I was really keen I could nick the speedo off the gt550A and tape it to the 750 and see if it still reads ok.

How precise would you expect the speedo to be calibrated? They are not that precise from stock.
Both the cb360 & cl450 show about 40mph in a 40mph zone (in those areas that show your speed).  The Suzuki shows 50+.

It's the right clock for the bike.  It's a gt750.  I have had the bike for many years and don't remember if the speedo issue has always been there or has got worse over time.  What could be a problem is if the speedo drive/wheel (front) is off a gt550. I think they are a different gearing.
I have been quoted 150 quid to check the speedo.

I will ask "Kent400" to look at a cb550 clock, which I have had from new.  It's slow to rise in mph and slow to fall back to zero.  This time I know the clock used to be ok.

All these things are getting on for 50 years old.  Did they ever expect them to be working all these years later.

So I need to get one of the speedo's recalibrated.  Its showing 85mph+ at 70.  I have put up with it for years but have decided to get it sorted.

Just wondering what is a good price for such a bit of work.  The clock is in goodish order...... just a not so accurate.

It's off an **750.

The Black Bomber Board / Re: Bits of metal found near inlet valve
« on: January 02, 2024, 02:28:54 PM »
Well, I have pulled the cam chain tensioner out and expected to see some problem with it.....
For good or bad, it seems to be ok.

It would be better to find out what's wrong without pulling the engine apart.  It's not been apart before, and I would prefer it to stay that way.

The Black Bomber Board / Bits of metal found near inlet valve
« on: December 31, 2023, 12:25:58 PM »
Hello, I have owned the bike for over 11 years.  Its done at least 5k miles and has had several oil changes.  I decided to do a general service and check all the usual things.  Its been running ok, but it's winter time so never a better time.

I thought to check the valve clearance on all valves, so off with both the covers.  On the LH inlet side, there were some metal bits around the valve stem.

and a pic of the bits of metal.  A solid ring of sorts

I am wondering if the cam chain tensioner has started to break up.  The cam chain is not as tight as I expected.
Is it possible to remove the lower cam tensioner (below the carbs) without taking the head off.

Has anybody else found bits like these.

Misc / Open / Re: Keihin carb fuel pipe fix
« on: December 03, 2023, 10:36:49 AM »
These carbs are off a cl450k5.  I had to change the fuel lines to more resilient E10 proof fuel lines,

There does not seem to be any sign of soldering, either on the carb or the brass? fitment.  It looks like nothing except a push fit.  Is there a slight taper in the carb body?.

I would prefer to solder the thing back in, but don't want to wreak the carb body.  I only have a "hobby" soldering iron.
I could heat up the brass fitment to be very hot and push it into the carb and apply flux & solder.

Some adhesive does seem the safest route.

The brass? bit

Hello, Just managed to pull the Brass fuel pipe connector out of the Keihin carb.  See pic.

Does "super glue" work to hold these things back in.  Not sure if "soldering" would work.

Misc / Open / Re: Nuts on inner tubes
« on: September 30, 2023, 10:27:58 PM »
One nut in, the other out has worked well for years.  Or has seemed too.  The only flat tyres have been due to nails/screws etc. 
I have seen other ways of securing the valve or using the two nuts.  Example below....

I had not seen the alternative way or had it mentioned......

The new setup that failed was on a 750 parallel twin with loads of torque, which used two tyre locks to keep the tyre in place.  Maybe they failed.  I dont know.
I will try the 2nd pic method and check that those tyre locks do actually grip and hold the tyre.

Misc / Open / Nuts on inner tubes

You would have thought that after many years of changing tyres and tubes I would not need to ask the question.....
In the pic below .......

Does one nut stay inside the rim and the other outside.  I have done it like this for years, but doubt has crept in.
Last week, I put a brand-new tyre and tube + rim tape on a rear wheel.  Within 35 miles the inner tube failed for some reason.  Not at the valve but within 15 cm.  The tyre seems ok.  I was still running the tyre/tube in.

A good carb bench sync costs nowt.

That's what I have always done.  If all the carbs do the same thing, it's a starting point.  For some reason, I have the urge to see how "balanced" they really are.
I think the 2 single carb bikes are free of sin.
4 of the Suzuki triples might show something of interest.
4 of the 4 stroke twins are ideal for a look at...... except they all don't have take off points for carb balancing
the only in-line 4 is an ideal candidate.

I need to check how many of these bikes actually can be carb balanced.  The xs650 and cl450 dont have the necessary bits.  I thought they all did.

Misc / Open / Carb Balancer kit
« on: September 20, 2023, 02:44:38 PM »
I am finally looking at getting one of these carb Balancer kits.  One of the 4 gauge ones.

It seems that there are a few sets of 4 gauge ones on "that" auction site.  Starting at 25 quid.

So my question is..... Is there much difference between the 25 quid sets and the 60 quid ones.  I guess the more expensive ones are more accurate?.

Or are the cheaper ones good enough.

SOHC Singles & Twins / Re: Any good for a first project?
« on: September 20, 2023, 02:32:40 PM »
I have the same model in blue.  The front drum brake one.  Easy to sort out.  Cheap(ish) to restore.  The 360 is far better than the 250.  Easy engine to repair.  Best if there are no rattles/smoke from engine, but can be sorted.  Looks like a good starting point - not that expensive if engine ok.

CMS  has 3 original ones 16022369004 but guess what £135 plus postage.

But there is a difference between there being no alternatives and a painful replacement.

At least the pain goes away over time - or just gets replaced with another.

Final report.
Spare carb diaphragm was ok and fitted.

Bike now back to its rampant best. 

Good to see that DS has spares.

Thanks
