Facebook is for 'me me me' stuff, real things that might have (or need to have) some longer value shouldn't be anywhere near it.

I agree with Simon whole heartedly. I`ve never seen the need for Facebook.

Re: 4G Grease Dashpot 464261

Paul, To refresh my memory I have removed the knob of the dashpot and left the main part screwed into the mag/distributor. There is a wire in the knob. There are two machined grooves or channels on the inside of the grease cylinder of the main part. When the knob is screwed onto the main part the en...

Re: 4G Grease Dashpot 464261

Paul,
If I remember correctly there is supposed to be a wire spring clip that prevents the dashpot knob from unscrewing on its own.
I can`t make out from your photos if your original dashpot has the clip or not. I think this is an important part of the dashpot.

I haven't yet had any dealings with Brightspark but I have a magneto sitting on the shelf with the same problem as yours and intend to use one of their condensers to repair it when I get around to it.

Re: Nh 350

Re: 1948 Iron 4G Coil Ignition

BUT how do I check the Distributor Timing, to be sure the spark is at 8mm BTDC ? Can`t you put a couple of centre-punch marks on the end of the front crankshaft, one for TDC and one for fully advanced? This can be done by putting a stick or wire down the plug hole. Remove the rocker box lid to make...

Re: My 4G Restoration Blog

So it looks like I have the correct original washers for '39 type girder forks with auxiliary springs but I haven't found any other photos on the internet of bikes with these washers. As expected, these 1/8" washers are also listed in the W/NG Parts Book, but can I find a photo of a W/NG with ...

Re: "That hasn't happened before . . ."

When I was putting together my Sq4 I discovered that a previous owner had attached the sprocket to the hub with bolts of the wrong thread. I forget if they were metric, UNF, UNC or something else. The threads in the hub were not totally ruined so I installed the correct CEI bolts with Loctite but, b...

Re: 1955 NH gearbox oil change

How much oil is required? Hello David, Mr.Haycraft says: "All 1952 and later Burman boxes have an oil level plug located also on the kick-starter end casing; to top up the gearbox to the maximum permissible level, it is only necessary to pour in engine oil through the filler-cap orifice until ...
