Re: Gasket or not?

Doug Hele came up with a fix using shims to reduce movement of the damper piston and reduce the rattle. AN may still have some, 48.0263 Shim .005", although there's a strong chance they'll need cleaning. I hadn't heard of that before......you are right, AN do have some in stock so I'll order a few,...

Gasket or not?

Hi all, I took my Classic out for a 30 mile spin to the pub and back last night and it is running like a watch, super smooth and responsive, it would be near perfect if the forks didn't chatter evil ......but that's an incurable issue as I understand it and not the subject of this post. One of the a...

Update on my carb saga; I've just done twenty miles and it's a different bike Very Happy ......it's lovely now, I was pretty much convinced it was fixed from the moment it started, it just sounded so different, the spitting and hesitation is all gone, once she is up to temperature the idle is a rock...

Re: Wiring route

Found it......(obvious once you spot it) a little cut out just underneath the mounting bolt, routes the wires away from harm nicely...... I still wish they were sleeved at the point where they pass the metal cover plate......but problem solved in any event.

Hmm......that's a shame as mine has a very slow leak and I have the Suzuki parts......there are many XS750 fuel taps and overhaul kits on ebay, you could try asking one of the sellers for the dimensions of the seals.

Re: Starter Sprag slipping

I was looking at the starter today as I have the right side carb off.....on the face of it, it looks reasonably easy, one of the bolts is a bit hard to get at, but then I had a look at the other side and it looks like it can't be withdrawn without dismantling half the bike........lets hope that is o...

Re: Starter Sprag slipping

Now if it were the starter motor that needs replacing, that's very character-building.
That must be the issue I had at the back of my mind.......lets hope the starter motor is an exceptionally good quality reliable part.... wink

Re: Carb adjustment

what is important are good O Rings in the outer part As mentioned previously I have had a couple of issues with these O rings, they seem to swell, lose all their tension and no longer do the job, so this time I'm trying a generic nitrile rubber O ring that seems to be a good smooth fit and is suppo...

Re: Carb adjustment

As a (hopefully) last word on this subject, looking at the starter valve body, it has a smooth internal surface and the valve spindle turns inside that, but although it's a smooth fit, it is by no means a perfect smooth fit, there is play, so I wonder how it retains the fuel that passes through it. ...

Do you think this jet has no function then despite the fact it does connect to the venturi of the carb?

Re: Carb adjustment

In discussion with another ex-Norton technician, we came to the conclusion that the brass plug/jet only blanks of a passageway, the rectangular hole being one open end of that passageway. Hi Richard, that's interesting.......are you saying that 'jet' is placed there simply to block the passageway a...

Re: Carb adjustment

Thank you for that, I haven't removed the enrichment device, mainly because the previous owner replaced the O rings just before I bought it.....however, no amount of spraying carb cleaner (as best possible) into that jet seems to produce any flow elsewhere, it seems to be a cul de sac. I will try re...

Re: Carb adjustment

Following on, I have adapted a gasket which was simple enough, however, before I put this back together I would like to be certain of something concerning the idle air mixture; I can see where it is drawn through the void created by the 'flat' in the outlet housing and thence into the idle tube, but...

Re: Carb adjustment

I did wonder if I'd got the 'wrong end' of the stick so to speak.......and having looked at my parts book it shows a cut out in the gasket for the left side carb and comments that it's for twin rotor idle. I'm pretty sure the gasket will have come from Norton as part of an overhaul kit, and looking ...

Re: Carb adjustment

.check the gasket between the carburettor and its inlet casting. Original Norton ones were symmetrical but the Burlen ones can be fitted upside down, blanking off the air passage to the vacuum chamber. That really screws up the carburation. Hi Richard, as suggested I've had a look at these gaskets ...

I believe the only way around the ethanol issue (at the moment) is to use the high octane unleaded fuels which form what I have read usually don't contain ethanol whereas the basic 95 will always have the ghastly crap as part of the mix.

Re: Fuse Block

That's an M8 thread whereas the Norton part is M6.
Sorry, that was just me being lazy, when I looked at these a while back they did lots of variations of this fitting in stainless, possibly brass etc, I suspect they will have an M6 version.
